The best organic fertilizers match their nutrient blend and application style to the plants you grow, rather than relying on one formula for every job. I’d put Dr. Earth Organic 5 Tomato, Vegetable & Herb Fertilizer in the overall lead for its clear edible-garden focus, while Jobe’s Organics All-Purpose Granular Fertilizer suits gardeners who want a broad-use granular option and Alaska Fish Fertilizer offers a liquid choice for feeding plants through watering. The main tradeoffs are targeted versus all-purpose formulas, granular versus liquid application, and convenience versus the need to measure and reapply. Organic products can also vary in nutrient concentration and odor, so the label matters as much as the word “organic.” Read on for how all 15 picks differ and which one fits your garden.

Key Takeaways
- Dr. Earth Organic 5 stands apart as the clearest specialty choice for tomatoes, vegetables, and herbs; its focus makes more sense for an edible garden than a single all-purpose blend.
- Jobe’s All-Purpose Granular appears in both 4-pound and 16-pound sizes, making it easier to match the same broad-use formula to a small garden or a larger planting area.
- Alaska Fish Fertilizer and FoxFarm Big Bloom represent liquid feeding, while most other picks are granular; liquid formats suit watering routines but call for more frequent measuring and application.
- True Organic Blood Meal is a targeted nitrogen amendment, not a complete substitute for a balanced fertilizer, so it fits a specific soil or crop need rather than general feeding.
- Miracle-Gro Organic Indoor Plant Food is the lineup’s indoor-specific liquid option, while plant foods such as Plant-Tone and Back to the Roots are broader choices that may be less convenient for houseplant-only care.

More Details on Our Top Picks
Jobe’s Organics Granular Vegetable and Tomato Fertilizer, 4 lb
For a gardener focused on tomatoes and vegetables, Jobe’s Organics Granular Vegetable and Tomato Fertilizer offers a targeted alternative to the broader 4-4-4 formula in Jobe’s Organics All-Purpose Granular Fertilizer, 16 lb. Its 2-5-3 NPK ratio places more emphasis on phosphorus than nitrogen, making it a distinct pick for a dedicated edible garden rather than a single feed for every plant around the yard. The granules are straightforward to measure and spread, and the product is OMRI listed for organic gardening. The tradeoff is upkeep: it calls for repeat applications every four to six weeks during the growing season, so it takes more routine attention than Dr. Earth Organic 5, which is described as feeding for several months. Choose this when crop-specific formulation matters more than long intervals between feedings.
Pros:- Formulated specifically for vegetables and tomatoes
- OMRI listed for organic gardening
- Granular form is easy to measure and apply
- Description says it is safe for use around children and pets
Cons:- Requires repeat applications every four to six weeks during the growing season
- The vegetable-and-tomato focus makes it less versatile than a balanced all-purpose fertilizer
Best for: Home gardeners growing tomatoes and vegetables who want an OMRI-listed granular fertilizer with a clearly stated nutrient ratio.
Not ideal for: Gardeners looking for one fertilizer for a mixed landscape or fewer seasonal applications; its crop focus is narrow and it needs repeat feeding.
- Brand:Jobe’s Organics
- Form:Granules
- Weight:4 lb
- NPK ratio:2-5-3
- Target plants:Vegetables and tomatoes
- Application frequency:Every 4–6 weeks or as needed during the growing season
- Organic certification:OMRI listed for organic gardening
Our verdict“Pick this for a dedicated tomato or vegetable garden when a crop-focused, OMRI-listed granular formula matters more than longer feeding intervals.”
Organic Plant Magic Fertilizer and Plant Food, 1/2 lb
Organic Plant Magic Fertilizer and Plant Food is the flexible pick for people feeding a changing mix of houseplants, herbs, flowers, vegetables, and fruit. A half-pound of powder makes 32+ gallons, so one container can serve many pots and garden beds without storing a bulky bag of granules. Unlike Jobe’s Organics Granular Vegetable and Tomato Fertilizer, it is not limited to a specific crop group: mix it into water and apply it to soil or foliage. The formula also lists beneficial bacteria, mycorrhizae, and trace minerals. That versatility comes with extra prep, since each application needs mixing, and its nutrient percentages are not provided. Compared with Dr. Earth Organic 5, which is positioned for tomatoes, vegetables, and herbs, this is the more adaptable option—but buyers who want a transparent NPK ratio may prefer a labeled granular fertilizer.
Pros:- One concentrate is suitable for a wide range of indoor and outdoor plants
- Makes 32+ gallons of plant food
- Includes beneficial bacteria, mycorrhizae, and trace minerals
Cons:- Must be mixed with water before every application
- Nutrient percentages are not provided in the product description
Best for: Plant owners who care for a varied collection of indoor plants and outdoor edibles and are comfortable mixing a water-soluble concentrate.
Not ideal for: Gardeners who want a ready-to-spread product or need a stated NPK ratio to match fertilizer to a specific crop.
- Form:Powder
- Weight:8 ounces (1/2 lb)
- Coverage:32+ gallons
- Mixing ratio:1 tablespoon per 1 gallon of water
- Application method:Mix with water; apply to soil or foliage
- Suitable for:Bonsai, herbs, vegetables, flowers, fruit, trees, gardens, and indoor plants
- Pack count:1
Our verdict“Choose this concentrate for a mixed indoor-outdoor plant collection if broad use matters more to you than a published nutrient ratio or ready-to-use granules.”
Dr. Earth Organic 5 Tomato, Vegetable & Herb Fertilizer, 4 lb
When frequent reapplication is the main frustration, Dr. Earth Organic 5 Tomato, Vegetable & Herb Fertilizer has a useful advantage: its product description says it feeds plants for several months. That sets it apart from Jobe’s Organics Granular Vegetable and Tomato Fertilizer, which calls for feeding every four to six weeks, and from Jobe’s Organics All-Purpose Granular Fertilizer, 16 lb, which is intended for use every two to three weeks. The granules are aimed at tomatoes, vegetables, and herbs, with beneficial soil microbes and mycorrhizae included to support nutrient availability and plant performance. This makes it a strong edible-garden choice for gardeners who want fewer feeding reminders. The tradeoff is a narrower use case than an all-purpose formula, and the provided product details do not state an NPK ratio or a precise application schedule.
Pros:- Described as feeding plants for several months
- Formulated for tomatoes, vegetables, and herbs
- Contains beneficial soil microbes and mycorrhizae
- Made with 100% organic and natural ingredients according to the description
Cons:- Product details do not provide an NPK ratio
- The description does not specify an application schedule
- More crop-focused than a general all-purpose fertilizer
Best for: Vegetable and herb gardeners who want a granular organic fertilizer described as feeding plants for several months rather than requiring frequent applications.
Not ideal for: Buyers who need a published NPK ratio, a detailed application schedule, or a single fertilizer for ornamental and edible plants alike.
- Brand:Dr. Earth
- Model:704P
- Weight:4 lb
- Unit count:64 ounces
- Form:Granules
- Target plants:Tomatoes, vegetables, and herbs
- Organic ingredients:100% organic and natural ingredients, according to the description
- Feeding duration:Feeds plants for several months, according to the description
Our verdict“Choose Dr. Earth Organic 5 for an edible garden if fewer feeding rounds matter more than a stated NPK ratio or all-purpose coverage.”
True Organic Blood Meal Fertilizer, 3 lb
True Organic Blood Meal Fertilizer is the specialist in this group, not a stand-in for a balanced organic feed. Its 12-0-0 NPK ratio makes it the clearest choice here when the goal is vigorous leafy growth in heavy feeders such as spinach, broccoli, and corn. That sharply contrasts with Jobe’s Organics All-Purpose Granular Fertilizer, 16 lb, whose 4-4-4 ratio supplies a more even mix for varied plants, and with Dr. Earth Organic 5, which is targeted to vegetables and herbs but is described as a broader plant food. The blood meal can be used in beds or containers and covers up to 104 square feet per bag. Its limitation is equally clear: with no listed phosphorus or potassium, it is not a complete nutrient solution for gardeners seeking balanced feeding.
Pros:- High-nitrogen 12-0-0 formula supports leafy vegetative growth
- Suitable for in-ground and container plants
- One 3 lb bag covers up to 104 sq. ft.
- Made with organic inputs and produced in the USA
Cons:- Provides nitrogen only in the listed NPK ratio, rather than balanced nutrients
- The listed application schedule is spring and fall, which may not suit gardeners seeking more frequent, adjustable feeding
Best for: Growers of leafy vegetables and other heavy feeders who want a high-nitrogen organic fertilizer for in-ground beds or containers.
Not ideal for: Gardeners seeking one balanced fertilizer for fruiting crops, flowers, or a mixed garden; its 12-0-0 formula is specialized for vegetative growth.
- Brand:True Organic
- Form:Granules
- Weight:3 lb
- NPK ratio:12-0-0
- Coverage:Up to 104 sq. ft.
- Application:Spring and fall
- Suitable for:In-ground and container plants
- Made in:USA
Our verdict“Choose this for a leafy-crop nitrogen boost, but use a balanced fertilizer instead if you need one product for a mixed garden.”
Jobe’s Organics All-Purpose Granular Fertilizer, 16 lb
For gardeners feeding several kinds of plants, Jobe’s Organics All-Purpose Granular Fertilizer, 16 lb is the broad-coverage pick. Its balanced 4-4-4 NPK formula is designed for vegetables, flowers, trees, and shrubs, unlike True Organic Blood Meal, which is a high-nitrogen specialist, or Jobe’s Organics Vegetable and Tomato Fertilizer, which focuses on edible crops. The 16 lb bag suits a larger planting area or a gardener who wants one formula across mixed beds. It is also OMRI listed and granular, so measuring and spreading are straightforward. The compromise is a demanding feeding rhythm: the product calls for applications every two to three weeks during the growing season. That is more frequent than Jobe’s vegetable-and-tomato formula and less convenient for anyone prioritizing longer intervals between applications.
Pros:- Balanced 4-4-4 NPK formula for varied plantings
- Suitable for vegetables, flowers, trees, shrubs, and other plants
- OMRI listed for organic gardening
- Granular form is easy to measure and apply
Cons:- Requires repeat applications every two to three weeks during the growing season
- The 16 lb bag may be excessive for a small garden or a few containers
Best for: Gardeners with large, mixed plantings of vegetables, flowers, trees, or shrubs who want a single OMRI-listed granular formula.
Not ideal for: Small-space gardeners or people who prefer infrequent feeding; the 16 lb bag may be more than needed, and applications are recommended every two to three weeks.
- Brand:Jobe’s Organics
- Form:Granules
- Weight:16 lb
- NPK ratio:4-4-4
- Suitable for:Vegetables, flowers, trees, shrubs, and other plants
- Application frequency:Every 2–3 weeks or as needed during the growing season
- Organic certification:OMRI listed
- Item type:All-purpose granular fertilizer
Our verdict“Choose this for a larger, varied garden that benefits from one balanced organic formula, provided you are comfortable with frequent applications.”
Back to the Roots Organic All-Purpose Plant Food (5 lb Value Size)
I’d choose this for gardeners who want an organic, plant-based formula for a mix of crops and ornamental plants. Kelp, alfalfa meal, mycorrhizae, and rock phosphate give it a broader ingredient profile than the single-purpose focus of Farmer’s Secret Fruit & Bloom Booster. Its 2-3-3 NPK is a mild, balanced option, and the no-burn formulation makes it approachable for newer gardeners. The tradeoff is that this powder must be mixed with water, so it takes more preparation than Miracle-Gro Organic All Purpose Plant Food’s granular, longer-feeding format. Its lower nitrogen level may also be a limiting factor for heavy-feeding plants that need stronger leafy growth. The five-pound size suits gardeners feeding a varied collection rather than just a few pots.
Pros:- Vegan, plant-based ingredients with no animal waste or synthetic chemicals
- Suitable for a wide range of garden and houseplant types
- No-burn formula is approachable for beginners when used as directed
- Includes mycorrhizae alongside kelp, alfalfa meal, and rock phosphate
Cons:- Powder must be mixed with water before application
- The 2-3-3 NPK provides less nitrogen than some heavy-feeding plants may need
Best for: Gardeners seeking a vegan fertilizer for a varied mix of herbs, vegetables, flowers, shrubs, and houseplants.
Not ideal for: Growers of heavy-feeding, leafy crops who want higher nitrogen or gardeners who prefer a ready-to-apply granular product.
- Brand:Back to the Roots
- Weight:5 lb
- NPK ratio:2-3-3
- Form:Powder
- Key ingredients:Kelp, alfalfa meal, mycorrhizae, rock phosphate
- Mixing ratio:1 tablespoon per gallon of water
- Target plants:Herbs, vegetables, fruits, flowers, shrubs
Our verdict“Choose this five-pound plant-based blend for versatile, gentle feeding across a varied garden, but look elsewhere for a higher-nitrogen formula or granular convenience.”
Miracle-Gro Organic All Purpose Plant Food, 3 lb
This granular option suits outdoor gardeners who would rather apply fertilizer to soil than mix a liquid feed at each use. Its feeding period of up to three months means fewer repeat applications than Alaska Fish Fertilizer, which is suggested every three weeks during the growing season. It is also made for both in-ground beds and containers, with separate guidance for garden coverage and a six-inch potted plant. The OMRI Listed status gives organic gardeners a clear-use credential. Its main limitation is scope: this product is intended for outdoor plants, unlike Back to the Roots Organic All-Purpose Plant Food, which also targets houseplants. I’d favor it for a vegetable or flower bed where a long interval between feedings matters, not for indoor collections or gardeners who want a liquid they can dose while watering.
Pros:- Granular application avoids mixing fertilizer into water
- Feeds plants for up to three months
- Suitable for outdoor in-ground beds and containers
- OMRI Listed for organic use
Cons:- Intended for outdoor plants, so it is not a fit for indoor plant feeding
- Granules are less convenient than liquid concentrates for dosing during routine watering
Best for: Outdoor gardeners who want a granular organic feed for vegetables, flowers, and container plants with fewer repeat applications.
Not ideal for: Indoor plant owners or gardeners seeking a liquid fertilizer for flexible, frequent dosing.
- Brand:Miracle-Gro
- Form:Granules
- Weight:3.1 lb
- Feeding duration:Up to 3 months
- Coverage:Approximately 20 sq. ft. per 3/4–1 cup
- Container guidance:1 tablespoon per 6-inch potted plant
- Organic listing:OMRI Listed
- Use:Outdoor in-ground and container plants
Our verdict“Pick this for outdoor beds and pots when extended feeding intervals matter more than indoor versatility or liquid application.”
Alaska Fish Fertilizer for Plants, OMRI Listed, 5-1-1
Among these choices, Alaska Fish Fertilizer is the clearest fit when I want a nitrogen-forward liquid feed for a broad range of garden plants. Its 5-1-1 ratio contrasts with the milder 2-3-3 blend in Back to the Roots Organic All-Purpose Plant Food, making Alaska the more targeted option for gardeners prioritizing nitrogen. The formula is OMRI Listed and can be used on vegetables, fruits, flowers, shrubs, trees, and container plants. It is designed not to burn plants when used as directed, but the routine asks for mixing with water and reapplication every three weeks during the growing season. That makes it more hands-on than Miracle-Gro Organic All Purpose Plant Food, which feeds for up to three months. Choose Alaska for repeat liquid feeding, not for low-maintenance schedules.
Pros:- 5-1-1 NPK offers more nitrogen emphasis than the balanced Back to the Roots blend
- OMRI Listed for organic gardening
- Suitable for vegetables, fruits, flowers, shrubs, trees, and container plants
- Designed not to burn plants when used as directed
Cons:- Requires dilution with water before application
- Suggested application every three weeks means a recurring feeding routine
Best for: Organic gardeners who want a nitrogen-forward liquid fertilizer for a range of outdoor crops, shrubs, trees, and containers.
Not ideal for: Gardeners who prefer infrequent applications or want a granular fertilizer that can be applied without mixing.
- Type:Liquid fish fertilizer
- NPK ratio:5-1-1
- Organic listing:OMRI Listed
- Application:Mix with water
- Suggested frequency:Every 3 weeks during the growing season
- Suitable plants:Vegetables, fruits, roses, shrubs, trees, and container plants
Our verdict“Choose Alaska for regular, nitrogen-focused liquid feeding across varied plants, but skip it if you want a fertilizer that lasts for months between applications.”
FoxFarm Big Bloom Liquid Plant Food, Organic Fertilizer, 1 Pint
FoxFarm Big Bloom is the most specifically oriented choice here for gardeners tending flowering and fruiting plants through different growth stages. Its earthworm castings and bat guano set it apart from Alaska Fish Fertilizer’s fish-based formula, while its low 0-0.5-0.7 NPK makes it less of a general-purpose source of major nutrients than the 2-3-3 Back to the Roots blend. The concentrate can be applied with a watering can, sprayer, or drip irrigation, which gives it more application flexibility than a simple pour-only routine. It is OMRI Listed and CDFA Organic Input Material certified. The tradeoff is a dilution rate of four tablespoons per gallon, plus directions recommending use every other watering; that is a more involved schedule than Miracle-Gro Organic All Purpose Plant Food’s extended feeding period.
Pros:- Made with earthworm castings and bat guano
- Designed for flowering and fruiting plants across growth stages
- Can be applied by watering can, sprayer, or drip irrigation
- OMRI Listed and CDFA Organic Input Material certified
Cons:- Must be diluted at four tablespoons per gallon of water
- Recommended use every other watering can create a frequent feeding routine
- Low 0-0.5-0.7 NPK makes it less suitable as a sole source of stronger general nutrition
Best for: Gardeners growing flowers or fruiting plants who want a liquid supplement usable through multiple growth stages and application systems.
Not ideal for: Buyers seeking a simple, broad-spectrum fertilizer with a more substantial NPK ratio or a long interval between feedings.
- Brand:FoxFarm
- Product type:Liquid plant food concentrate
- Volume:16 fluid ounces (1 pint)
- NPK:0-0.5-0.7
- Ingredients:Earthworm castings and bat guano
- Application rate:4 tablespoons (60 mL) per gallon (4 L) of water
- Recommended use:Flowering and fruiting plants; all growth stages
- Certifications:OMRI Listed; CDFA Organic Input Material certified
Our verdict“Choose Big Bloom for flexible liquid feeding of flowering and fruiting plants, but not as the simplest or strongest general-purpose fertilizer in this group.”
Farmer’s Secret Fruit & Bloom Booster Fertilizer, 16 fl oz
Farmer’s Secret is the most season-specific pick in this group: it is aimed at fruit, vegetable, and flower production, especially in late summer and early fall. That focus separates it from Back to the Roots Organic All-Purpose Plant Food, which is designed for a wider mix of plants and routine general feeding. Its concentrate goes a long way by the stated dilution—one teaspoon per two gallons of water—and it can be poured or sprayed onto plants every two to four weeks. The narrow timing is also its main drawback: gardeners looking for an all-season, all-purpose fertilizer may get more flexibility from FoxFarm Big Bloom, which is recommended for flowering and fruiting plants across growth stages. The supplied product details do not specify an organic listing, so I would not treat organic certification as established from this data alone.
Pros:- Very concentrated stated mixing ratio of 1 teaspoon per 2 gallons of water
- Targets fruit-, vegetable-, and flower-producing plants
- Can be applied by pouring or spraying
- Recommended application interval is every 2–4 weeks
Cons:- Formulated especially for late-season use, limiting its fit as an all-season option
- Requires dilution before application
- The supplied product data does not specify an organic certification or listing
Best for: Gardeners supporting fruiting vegetables, fruits, and flowers with a diluted feed during late summer and early fall.
Not ideal for: Buyers seeking a verified organic-listed product or a single fertilizer for broad, year-round plant feeding.
- Brand:Farmer’s Secret
- Product type:Liquid fertilizer
- Volume:16 fluid ounces
- Item weight:1.4 lb
- Mixing ratio:1 teaspoon per 2 gallons of water
- Application method:Pour or spray
- Target plants:Fruit-, vegetable-, and flower-producing plants
- Recommended timing and frequency:Late summer and early fall; every 2–4 weeks
Our verdict“Choose Farmer’s Secret for concentrated late-season feeding of fruiting and flowering plants, but pick another option if organic listing or year-round versatility is a priority.”
Jobe’s Organics All-Purpose Granular Fertilizer, 4 lb
Jobe’s earns this spot for gardeners who want one organic granular formula for a mixed planting rather than a product tailored to a single crop. Its 4-4-4 analysis provides balanced nutrients for vegetables, flowers, shrubs, and trees, while beneficial microorganisms are intended to support soil activity as organic material breaks down. Compared with Down To Earth Organic Vegetable Garden Fertilizer, which is specifically framed for edible beds, Jobe’s gives up that vegetable-focused positioning in favor of broader use. The 4-pound bag is also easier to manage for modest gardens than the 16-pound Jobe’s option elsewhere in the roundup. The tradeoff is limited guidance in the supplied product details: application frequency and detailed directions are not specified, so buyers should check the package before applying.
Pros:- 100% organic formula
- Balanced 4-4-4 analysis suits a broad range of plants
- Contains beneficial microorganisms intended to support living soil
- Granular form is less prone to splashing than liquid feeds
Cons:- Supplied product details do not specify application frequency
- Does not offer the crop-specific focus of Down To Earth’s vegetable garden formula
Best for: Home gardeners maintaining a small mix of vegetables, flowers, shrubs, and trees who want one balanced organic granule.
Not ideal for: Gardeners who need clearly specified feeding intervals or a fertilizer formulated specifically for vegetables and herbs.
- Brand:Jobe’s Organics
- Form:Granules
- Weight:4 pounds
- NPK ratio:4-4-4
- Intended use:Gardening
- Target species:Plants
- Model number:09526
Our verdict“Choose this 4-pound Jobe’s bag for balanced organic feeding across a varied garden, but check its package directions if you need a defined schedule.”
Espoma Organic Plant-Tone 5-3-3 All-Purpose Plant Food, 4 lb Bags, Pack of 2
Plant-Tone is the fit for gardeners who prefer slow-release granules and want a two-bag supply for several kinds of plants. Its 5-3-3 analysis with 5% calcium differs from the more evenly balanced 4-4-4 formulas in Jobe’s All-Purpose and Down To Earth Vegetable Garden Fertilizer; the added calcium and higher first number give buyers a distinct nutrient profile to compare against those options. Espoma also provides ready-to-use directions: apply to soil and water thoroughly, with no mixing step. The pack contains two 4-pound bags, which is more stock than a single small bag but may be excessive for a few pots. Feeding intervals vary by plant and season, and thorough watering is part of the application rather than an optional convenience.
Pros:- Slow-release formula for gradual nutrient delivery
- Ready to apply without mixing
- Suitable for flowers, vegetables, trees, and shrubs
- Includes 5% calcium and Espoma Bio-tone formula
Cons:- Application frequency varies by plant type and season
- Requires thorough watering after application
- Two 4-pound bags may be more supply than a small garden needs
Best for: Gardeners with multiple flower, vegetable, tree, or shrub plantings who want slow-release granules in a two-bag pack.
Not ideal for: People caring for only a few houseplants or anyone who cannot water the soil after applying fertilizer.
- Brand:Espoma
- Fertilizer analysis:5-3-3
- Calcium:5%
- Form:Granules
- Pack size:2 bags
- Bag weight:4 lb each; 8 lb total
- Application:Apply to soil and water thoroughly; no mixing required
- Organic gardening status:Approved; registered Organic Input Material
Our verdict“Pick Plant-Tone if you want a larger supply of slow-release organic granules and can follow plant-specific timing and watering directions.”
Miracle-Gro Organic Indoor Plant Food, 8 fl oz, 2-Pack
This is the lineup’s clearest choice for houseplant owners who want measured liquid feeding instead of spreading granules across soil. The smart-dose cap gives a straightforward squeeze-based routine: one squeeze for small pots, two for pots larger than 6 inches, or two squeezes diluted in a quart of water. Its 94% plant-based ingredients and 1-0.5-1 analysis set it apart from the stronger 4-4-4 granular options such as Jobe’s All-Purpose, which are aimed at broader garden use. Miracle-Gro also lists flowers, vegetables, and herbs among suitable plants, so it is not limited to indoor foliage. The tradeoff is modest volume: two 8-ounce bottles can run out faster across a large collection, and the description recommends a separate potting mix for best results.
Pros:- Made with 94% plant-based fertilizer ingredients
- Smart-dose cap offers pot-size-based directions
- Can be used for houseplants, flowers, vegetables, and herbs
- Liquid form can be diluted with water
Cons:- Two 8-ounce bottles provide limited volume for a large plant collection
- The product description recommends a potting mix sold separately
- Lower NPK numbers than the 4-4-4 granular options in this roundup
Best for: Houseplant owners who want a liquid organic feed with a simple dose guide for small and medium pots.
Not ideal for: Gardeners feeding large outdoor beds or anyone seeking a granular product that can be worked into soil.
- Brand:Miracle-Gro
- Form:Liquid
- Pack size:2 bottles
- Bottle volume:8 fl oz each; 16 fl oz total
- Plant-based ingredients:94%
- NPK:1-0.5-1
- Target plants:Houseplants, flowers, vegetables, and herbs
- Application:1 squeeze for small pots; 2 for pots over 6 inches, or dilute 2 squeezes in 1 quart of water
Our verdict“Choose this Miracle-Gro liquid for convenient, measured feeding of indoor pots, not for covering a large garden bed.”
Down To Earth Organic Vegetable Garden Fertilizer, 5 lb
Down To Earth is the most clearly targeted pick here for gardeners tending vegetables, herbs, and greens. Its slow-release 4-4-4 granules can go straight onto soil or be mixed into garden beds, giving growers two practical ways to work it into a planting routine. That focus separates it from Jobe’s All-Purpose 4-4-4, which covers shrubs, trees, and flowers as well as vegetables; if edible crops are the priority, Down To Earth’s positioning is more direct. The 5-pound bag also offers more product than Jobe’s 4-pound all-purpose bag, though the supplied details do not specify coverage or feeding intervals. Its chief limitation is scope: unlike Espoma Plant-Tone, it is not presented as a broad-use choice for ornamental plantings, and it is not a general-purpose lawn fertilizer.
Pros:- Slow-release 4-4-4 formula
- Designed for vegetables, herbs, and greens
- Can be applied to soil or mixed into garden beds
- Suitable for containers and raised beds
Cons:- Not presented as a general-purpose lawn fertilizer
- Product details do not specify coverage or application frequency
- More narrowly positioned than Jobe’s all-purpose formula for mixed gardens
Best for: Vegetable and herb growers using garden beds, raised beds, or containers who want slow-release organic granules.
Not ideal for: Buyers looking for a single fertilizer for lawns and a mixed collection of ornamentals, shrubs, and trees.
- Brand:Down To Earth
- Model number:100532059
- Weight:5 lb
- Form:Granules
- NPK ratio:4-4-4
- Application:Apply directly to soil or mix into garden beds
- Suitable for:Vegetables, herbs, greens, containers, and raised beds
Our verdict“Choose Down To Earth for edible beds and raised planters; pick Jobe’s All-Purpose instead if you need one formula for ornamentals too.”
Burpee All-Purpose Organic Granular Plant Food, 4 lb
Burpee stands out for gardeners who value a stated feeding window: its granular formula starts releasing nutrients immediately and feeds for up to three months. That duration gives it an advantage over the products here whose supplied descriptions do not specify how long feeding lasts, including Jobe’s All-Purpose. It is also OMRI Listed and intended for vegetables, flowers, herbs, and containers, with calcium and beneficial microbes included in the formula. The stated coverage of 213 square feet helps buyers estimate whether one bag fits their planting area. Those strengths come with a practical caveat: granules need careful placement to limit mess, and the product details stress following application instructions. Unlike the liquid Miracle-Gro Indoor Plant Food, Burpee is better suited to soil-based application than measured feeding of individual pots.
Pros:- OMRI Listed for organic gardening
- Feeds for up to three months
- Suitable for vegetables, flowers, herbs, and containers
- Lists coverage of 213 square feet and includes beneficial microbes
Cons:- Granules require careful application to limit mess
- Results depend on following the product’s application instructions
- Less suited than Miracle-Gro’s liquid feed to measured dosing for individual indoor pots
Best for: Organic gardeners who want a granular feed with a stated duration and coverage figure for vegetables, flowers, herbs, or containers.
Not ideal for: Houseplant owners seeking a liquid, pot-by-pot dosing method or buyers who prefer products with fully supplied application directions.
- Brand:Burpee
- Weight:4 lbs
- Form:Granules
- Coverage:213 square feet
- Certification:OMRI Listed
- Feeding duration:Up to 3 months
- Suitable for:Vegetables, flowers, herbs, and containers
Our verdict“Pick Burpee if a stated feeding duration and coverage figure matter more than liquid-style precision for individual pots.”
How We Picked
I compared the 15 products by intended use, nutrient focus, and application format, then considered how clearly each product fits a real buying need. A fertilizer for vegetables and herbs should be judged differently from a bloom booster, a nitrogen-focused blood meal, or a liquid formulated for indoor plants. I also weighed pack size and versatility: larger bags can make sense for established beds, while a small container or a narrowly targeted formula may suit a more limited task.
The ranking favors products with a clear use case and practical fit, not a claim that one formula is right for every plant. Broad-use granular products rank well for gardeners feeding several kinds of plants; specialized options rank higher for the crop or feeding job they serve best. I also account for tradeoffs such as liquid measuring, potential odor from animal-derived ingredients, and the risk of using a targeted amendment as though it were a complete fertilizer. Product labels should guide application rates and confirm whether a formula suits a particular plant or growing method.

Factors to Consider When Choosing Best Organic Fertilizers
Before choosing from this lineup, I’d start with the job the fertilizer needs to do. These broader factors can help prevent common mismatches that product descriptions alone may not resolve.
Match the Nutrient Goal to the Plant
Start with the plant’s growth stage and any soil-test findings, rather than choosing by the word “organic” alone. Nitrogen supports leafy growth, while phosphorus and potassium play different roles in plant development; the N-P-K numbers summarize those nutrients but do not describe every feature of a formula. A nitrogen-focused product such as blood meal is not a stand-in for a balanced feed, and a bloom-oriented product should not automatically be used for every crop. Applying a nutrient the soil already has can be wasteful and may upset nutrient balance. When the need is unclear, a soil test and the product label are more useful than guessing from leaf color alone.
Choose Granular or Liquid Around Your Routine
Granular fertilizers are generally spread into or over soil, making them convenient for beds and larger planting areas. Liquids are mixed or diluted for watering, which can suit containers and gardeners who already feed plants during watering. The formats are not interchangeable by schedule: follow each label’s directions instead of assuming a liquid needs daily use or that every granular product lasts the same amount of time. A common mistake is to apply a concentrated liquid without measuring, which can deliver more than intended. Pick the format you can use consistently and safely, not just the one that sounds faster.
Size the Package to Your Planting Area
A large bag can reduce repeat purchases for a substantial garden, but it may be a poor fit if you only fertilize a few containers or one raised bed. Smaller packages also make sense when you are trying a formula for the first time or have limited dry storage. Compare the label’s application rate and coverage guidance, not just the package weight, because products can call for different amounts. Keep granular fertilizer dry and sealed as directed so it remains practical to handle between uses. If the product has a narrow purpose, avoid buying more than you can use for that job.
Check Organic Claims and Growing Context
“Organic” can describe ingredient sourcing or a product’s eligibility for certain uses, but it does not mean every fertilizer is approved for every growing system. If certification or use in organic production matters to you, check the exact product label and the relevant listing rather than relying on general packaging language. Also confirm whether the fertilizer is intended for outdoor beds, containers, or indoor plants. Some products contain animal-derived ingredients that may have a noticeable smell, which matters near patios or in indoor spaces. A formula that fits your principles still needs to fit the plants and setting.
Treat Specialty Amendments as Specific Tools
Targeted products can be useful when they address a known need, but they are easier to misuse as a universal feed. Blood meal, for example, focuses on nitrogen; a bloom booster has a different purpose from an all-purpose plant food. Before adding a specialty amendment, check the plant’s requirements and, when possible, soil-test results. Avoid stacking several fertilizers with overlapping nutrients unless their labels and the plant’s needs support that plan. For a mixed garden with no clear deficiency, a labeled all-purpose product is often a simpler starting point.
Factor in Handling, Storage, and Application
Consider where you will apply and store the fertilizer before settling on a format. Granules can be simpler to portion across beds, while liquids require mixing equipment and careful measurement; either can be inconvenient if your routine or storage space does not suit it. Follow label directions for protective handling, application timing, and storage, and keep products away from children and pets. Do not assume that a natural-origin fertilizer can be applied without care or that more will produce better growth. Paying for a format that is easy to use correctly can be a better choice than buying a larger package you are reluctant to handle.
Frequently Asked Questions
Can I use one all-purpose organic fertilizer for vegetables, flowers, and houseplants?
Sometimes, but check the label for every plant and growing setting you have in mind. An all-purpose formula can simplify care across a mixed garden, while a crop-specific blend may better match vegetables or flowering plants. Houseplants also have different container and application needs from outdoor beds, so an outdoor product should not be assumed suitable indoors. Avoid feeding every plant on the same schedule just because you use the same product. Follow the label’s rates and adjust for each plant’s needs.
How do I choose between granular and liquid organic fertilizer?
Choose based on where and how you feed plants. Granules often suit garden beds and gardeners who prefer to apply fertilizer directly to soil, while liquids fit people who want to feed through watering or care for containers. The product’s directions determine how often and how much to apply, so the format alone does not establish a schedule. Liquids require careful dilution and measuring; granules need even application and suitable storage. If consistency is your main concern, pick the method you are most likely to use correctly.
Is a high-nitrogen product like blood meal enough to fertilize a vegetable garden?
Not necessarily. Blood meal is a targeted nitrogen source, so it may address a specific need but does not replace a balanced fertilizer in every garden. Too much nitrogen can encourage leafy growth at the expense of other growth goals, depending on the crop and conditions. Use a soil test and the product label to decide whether nitrogen is needed and how much to apply. If you are unsure what the soil lacks, a specialty amendment is a poor substitute for finding out first.
Does an OMRI listing mean a fertilizer is the best choice for my garden?
An OMRI listing can help buyers who need to check whether a product is permitted for use in organic production, but it does not tell you whether the nutrient profile suits your plants. You still need to match the formula to the crop, growing medium, and application directions. Listing status also does not mean a product is automatically suitable for every certification program or use, so verify the relevant requirements. For home gardeners who do not need certification, plant fit and ease of application may matter more. Read the product label rather than treating a listing as a complete recommendation.
Should I buy a larger fertilizer package if I have several types of plants?
Only if the formula suits those plants and you can use the package according to its directions before storage becomes a problem. A larger size can be practical for sizable beds when the product is genuinely broad-use, as with the 16-pound Jobe’s All-Purpose option in this lineup. It is less compelling if you mainly grow indoor plants or need a specialty nutrient for just one crop. Compare coverage guidance and application rates rather than package weight alone. Keep unused fertilizer stored as the label directs.
Conclusion
For most gardeners focused on edible crops, I’d start with Dr. Earth Organic 5 as the best overall fit because its stated use is specific to tomatoes, vegetables, and herbs. For broad-use granular feeding, Jobe’s Organics All-Purpose is the best value-style pick when you choose the package size that matches your garden; its 4-pound and 16-pound options serve different scales. I’d call Espoma Organic Plant-Tone the best premium-leaning choice for gardeners who want an established all-purpose formula in a two-bag pack, while Back to the Roots Organic All-Purpose Plant Food is a straightforward option for beginners seeking a general-purpose product. For specific needs, choose Miracle-Gro Organic Indoor Plant Food for indoor plants, Alaska Fish Fertilizer for a liquid feeding format, or True Organic Blood Meal only when a nitrogen-focused amendment fits the job. The best pick is the one whose label, nutrient purpose, and application routine match your plants—not simply the one with the broadest claims.
