Grow More 0.2-0-0 EDDHA Iron Chelate for Greener Plants, 1lb Water Soluble
This water-soluble EDDHA chelated iron is engineered for problematic soils like caliche and adobe where pH exceeds 7. It delivers rapid greening by making iron readily available in alkaline conditions, outperforming other chelates in high pH environments. However, its 1 lb size limits its use for larger citrus groves, and it requires water application, making it less convenient for quick foliar feeding. Compared to DTPA options, its specificity for high pH soils makes it less versatile but unmatched for targeted correction in tough soils.
Pros:- Excellent in correcting iron deficiency in high pH soils
- Fast-acting, promotes lush green growth quickly
- Easy to dissolve and apply in water
Cons:- Limited to 1 lb packaging, less cost-effective for large areas
- Specific to alkaline soils, ineffective in acidic conditions
- Requires water application, not suitable for foliar use
Best for: Growers dealing with highly alkaline soils needing fast iron correction
Not ideal for: Gardeners with acidic soils or those seeking a larger quantity for extensive use
- Weight:1 lb
- Formulation:Water soluble

- Fast-acting:Yes
Our verdict“A highly effective choice for quick correction in alkaline soils, best suited for small-scale or targeted applications.”
Chelated Iron for Plants – Liquid Iron Supplement to Fix Chlorosis, Restore Green Leaves & Support Chlorophyll Production, 8 oz
This liquid chelated iron from TPS NUTRIENTS supports healthy, green foliage by providing an easily absorbed form of iron through roots. It’s ideal for regular maintenance in landscape trees and ornamentals, helping prevent chlorosis when used consistently. While its liquid form simplifies application, it may require frequent reapplications to sustain the lush color, especially in severe deficiencies. Compared with granular or solid options, this formula offers convenience but at a higher application frequency, which could add up for larger citrus groves.
Pros:- Supports vigorous, green foliage in various plants
- Easy to apply as a liquid, suitable for foliar or soil drench
- Made in the USA, ensuring quality
Cons:- Requires repeated applications for sustained effect
- May be less effective in severe deficiencies without frequent use
- Best for ornamental use, not large-scale farming
Best for: Home gardeners and landscapers seeking easy, regular iron supplementation
Not ideal for: Large-scale citrus farms needing bulk solutions or soil-specific formulations
- Brand:TPS NUTRIENTS
- Size:8 oz
- Application:Root and foliar
- Made in:USA
- Supports:Chlorophyll production
- Absorption:Efficient
Our verdict“This liquid chelate offers a straightforward way to maintain greening but demands regular use for best results.”
Bloom City Chelated Liquid Iron Supplement for Lawns & Plants, 8 oz
This chelated liquid iron is formulated to quickly restore green in lawns, gardens, and ornamentals, making it a flexible choice for diverse plants. Its liquid form ensures rapid absorption and visible greening within days, especially in iron-deficient plants. However, like other liquid forms, it may need frequent reapplications and proper dilution to avoid overfeeding. Compared to DTPA and EDDHA, this product is more suited for routine maintenance rather than correcting stubborn deficiencies in challenging soil conditions.
Pros:- Effective at restoring green color quickly
- Easy to apply, suitable for routine use
- Supports healthy growth in multiple plant types
Cons:- Regular reapplication needed for sustained greening
- Less effective in very high pH soils
- Requires proper dilution to prevent overfeeding
Best for: Gardeners seeking an easy, fast-acting solution for multiple plant types
Not ideal for: Large commercial citrus operations or soils with very high pH where DTPA or EDDHA are preferred
- Brand:Bloom City
- Model Number:liquid-iron-8-fba-upc-0323
- UPC:841401126209
- Unit Count:1
- Application:Lawn, garden, ornamental
- Best Sellers Rank:#3,535
- Made in:USA
Our verdict“A versatile, quick solution for small to medium gardens needing rapid greening with minimal fuss.”
Greenway Biotech Chelated Iron DTPA 11% – Water Soluble Fertilizer for Alkaline Soils, Corrects Iron Chlorosis, 1 Pound
This DTPA-based chelated iron excels in soils with pH up to 7.5, offering a versatile and effective solution for correcting iron chlorosis. Its 11% iron content delivers quick greening within 7-10 days, making it suitable for both foliar and soil applications. Unlike EDDHA, which is limited to very high pH soils, DTPA works well across a broader pH spectrum, providing reliable results in most garden conditions. The main tradeoff is that precise measurement is necessary to prevent overapplication, and repeated treatments might be needed for ongoing deficiencies.
Pros:- Effective across a broad pH range up to 7.5
- Quickly restores green leaves
- Versatile foliar, soil, and hydroponic use
Cons:- Requires careful measurement for application
- May need multiple treatments for persistent deficiencies
- Less effective in very high pH soils (>7.5)

Not ideal for: Soils with pH above 7.5 or for those seeking a long-term, slow-release product
- Iron Content:11%
- Application:Foliar, soil, hydroponic
- pH Range:4.0-7.5
- Weight:1 Pound
- Water Soluble:Yes
- Made in:USA
Our verdict“A dependable choice for quick correction in most garden soils, especially when pH is below 7.5.”

Factors to Consider When Choosing Best Chelated Iron For Yellowing Citrus Leaves
Choosing the right chelated iron for your citrus trees depends largely on your soil pH, application preference, and the urgency of greening. Understanding the differences among EDDHA, DTPA, and liquid forms can help you match a product to your specific needs. Here, we break down key factors to consider: soil conditions, application method, and how quickly you want to see results.Soil pH Compatibility
For soils with pH above 7, EDDHA chelates are usually the most effective, as they remain stable and available in alkaline conditions. DTPA is suitable for slightly lower pH ranges but still offers versatility for general use. Liquid iron supplements are best for routine foliar applications but may not suffice in highly alkaline soils without soil amendments.
Application Method and Convenience
Water-soluble powders like Grow More are excellent for soil drenching, especially when quick correction is needed in small areas. Liquid formulations such as those from TPS or Bloom City provide ease and speed, ideal for regular maintenance. Consider your garden size and how frequently you’re willing to reapply when choosing between these options.
Speed of Results and Longevity
Products like Greenway Biotech DTPA and Grow More EDDHA are designed for rapid greening, often within a week. Liquids are convenient for ongoing care but may require frequent reapplications. Slow-release or long-lasting formulations aren’t typically available in this lineup but are worth considering if you prefer less frequent dosing.
Frequently Asked Questions
How quickly can I expect to see results after applying chelated iron?
Most chelated iron products, especially DTPA and EDDHA formulations, can produce visible greening within 7 to 10 days if applied correctly. Liquid products often show faster results, sometimes within a few days, but consistent reapplication may be necessary for sustained color. Soil conditions and severity of deficiency also influence the speed of response.
Can I use chelated iron on all types of citrus trees?
Yes, chelated iron is generally safe for all citrus varieties, provided you follow application instructions. However, the method and frequency should be tailored to the severity of deficiency and soil pH. Always avoid overapplication, which can lead to nutrient imbalances or leaf burn.
Is chelated iron safe for the environment and beneficial insects?
Most chelated iron products are considered environmentally friendly when used as directed. They pose minimal risk to beneficial insects or soil microbes, especially when applied properly. Organic growers should look for products with certified organic inputs, although these specific options are generally safe for typical garden use.
Should I prefer foliar or soil application for citrus leaves?
Foliar applications provide rapid greening, especially in urgent cases of chlorosis, but often need to be repeated. Soil applications deliver nutrients to the roots for longer-term correction. Combining both methods can be effective, particularly with liquid formulas that are easy to spray and soil-drench products for sustained health.
How often should I reapply chelated iron during the growing season?
This depends on the severity of deficiency and the product used. Generally, soil drench or granular products may need reapplication every 4-6 weeks, while liquids might require weekly or bi-weekly treatments for ongoing maintenance. Always follow the specific product instructions for best results.
Conclusion
For citrus growers with high pH soils or persistent deficiencies, Grow More EDDHA offers speed and effectiveness in small applications. Those seeking a versatile, fast-acting solution across various soil types might prefer Greenway Biotech DTPA for broader pH range coverage. Home gardeners and landscapers aiming for easy, routine fertilization will find Bloom City Liquid Iron the most convenient, while larger-scale citrus farms should consider application logistics and may need to combine products for optimal results. Matching the product to your soil conditions, application method, and urgency of greening will yield the best citrus health outcomes.
