This article will show you how to make an self-irrigating pot from an ordinary PET bottle. You don’t have to be a professional DIYer. PET bottles can be recycled.

DIY Self Watering Planter – Make a Self-Irrigating Plant Pot with A Pet Bottle

Create a self-irrigating plant pot with a pet bottle

A PET bottle is all you need to make a self-irrigating container. Cut the bottom of the bottle. Next, make a small opening in the middle of the lid. Next, insert a piece or nylon tape or rope through the hole in your lid. Finally tie it to a bamboo stick or another long rod.

Finally, fill the bottle with water. Place it next to the potted plant. The water will slowly seep from the bottle into the soil, giving your plant a steady supply. This simple DIY project will ensure your plants have water even while you are away on vacation.

Watering Plants Often Is Guesswork

Watering plants can be considered an art by many gardeners. Every plant is unique and requires different amounts of water, depending on the season and weather conditions. Water plants can feel like a game and it can be hard to decide when to give them water.

  • Because not everyone is a professional plant geek, they don’t necessarily know the exact amount of water that your plant needs.
  • While the surface layer might be dry, the deeper earth beneath is moist and has decaying roots.
  • The weather can affect how hot or cold a plant needs watering. Your plant will need more or less water, depending on the weather.

A moisture meter can help you eliminate the guesswork from watering your plants. This simple tool will help you determine the amount of water your plants require based on current conditions. A moisture meter can help you ensure that your plants get the right amount of water. Moisture meters can also help you avoid overwatering which can cause root rot.

Is self-irrigating beautiful?

Algae growth within water reservoirs can not only be unsightly but also pose a risk to human and animal health. There are many factors that can contribute to algae growth. However, the most important factor is the presence and concentration of nutrients. By acting as a buffer between soil and water, lawns can prevent nutrient runoff.

Well-managed lawns help keep nutrients in the soil. Lawns also slow down water flow, giving the soil a chance absorb it before it goes away. A well-maintained lawn can help to prevent algae growth in water reservoirs.

Are all plants suitable for self-irrigating?

There are many answers.

  • Yes. This is true for plants that don’t need water or those that are in constant moisture. It also applies to ornamental uses. What is the difference? Because the plant only draws what it needs.
  • Not for all sizes of plants: A plastic bottle isn’t very large and if the plant grows too tall, it may tip over.

Self-irrigating plantsers have one of the biggest benefits: they reduce water waste. Self-irrigating plantsers prevent overwatering by storing water in a reservoir, and then delivering it to the roots when needed. Self-irrigating plants can also help improve plant health by maintaining a steady supply of water. Some plants may not be able to take self-irrigation.

If a self-irrigating poter is used, plants that are water-starved, like succulents and cacti, can suffer from too much moisture. Self-irrigating plantsers may not be necessary for plants that live in wetter areas. It is best to speak with a professional nurseryman or gardener if you are uncertain if a self-irrigating poter is the right choice for your plant.

Even though it is often overlooked, pots used to grow plants can have a major impact on their health. It is crucial to select the right pot size for your plant. Too large a pot can cause roots to spread too far, and too small a pot can hinder the plant’s growth.

It is important to consider the material of the pot. Although plastic pots can be inexpensive and light, they may not offer adequate drainage and break easily. Clay pots, on the other hand, are more heavy and fragile. However, they can withstand more moisture and allow it to escape. There is no perfect pot and each plant will have its own needs. However, it can make a huge difference in the long-term health of your plants if you take the time to choose the right pot.

The advantages of self-irrigation

Self-irrigation has the advantage of providing a steady water supply for the plants. This is especially helpful for plants susceptible to drying out such as succulents and cacti. These plants can be self-irrigated and watered up to once per week, or once per month depending on how big the reservoir is. This is less frequent than traditional watering which can be done daily, or multiple times per day.

Self-irrigation can be used for all kinds of plants, including succulents and cacti. Many plants thrive with regular water supplies. The roots absorb nutrients better and stay healthier when they are continuously supplied with water.

Hydroponics or soil cultivation can both be done by self-irrigation. Hydroponics allows you to add a special hydroponic fertilizer to each watering. For soil cultivation, this is not necessary as the soil will be kept moist by the self-irrigation system.

  • It uses constant water supply so there is less chance of it drying out.
  • Regular watering is essential for plants to thrive, especially during the hot summer months. Hand-watering can also prove time-consuming. This problem can be solved by using self-irrigation systems that deliver water directly to your plants’ roots.
  • It saves time and can help reduce water waste. The water will evaporate less before it reaches the roots. Self-irrigation is also a good option to prevent root rot because the roots don’t have to be constantly soaked in water. Self-irrigation systems have many benefits for you and your plants.
  • You may water less often: Depending on the size and climate in your garden centre, you might water once per week or less.
  • It is suitable for many flora types, including succulents and cacti as well as marsh. Access to water is essential for succulents and cacti to thrive.
  • Hydroponics or soil, the substrate type is irrelevant as the wick moves water to the roots. Hydroponics hydroponics hydroponics: Add hydroponic fertilizer each time you water.

Self-irrigation has many advantages over traditional methods for watering plants. It reduces water waste, perhaps the most important benefit. Self-irrigation means that plants only need water when they are needed. It is not a schedule. This is particularly important for areas that are drought-prone as it can help save water. Self-irrigation can also help reduce disease spread. Self-irrigation reduces the moisture available for fungal diseases by watering roots directly rather than wetting stems and leaves. Self-irrigation is a great way to keep your plants vigorous and healthy.

Self-irrigation drawback

Self-irrigating pots can be a great way for plants to stay hydrated and healthy. However, there are some potential drawbacks. The first is the need to refill the reservoir every few days. This can prove tedious for large plants.

You may also risk your plants drying out if you don’t refill the reservoir. Self-irrigating pots can weigh a lot when they are filled with water. Make sure you place them on a stable surface. Self-irrigating pots can be a great choice for people who want to ensure their plants have enough water. However, they do require some attention and care.

How do you water self-irrigating pots?

Self-irrigating pots are easy to water and require no effort. This means you won’t have to worry about your plants ever again. Just lift the pot, fill the reservoir with water and let it sit until the cap is just below it. If you forget to water your plants, water the soil and substrate the first time. You can ensure that your plants get enough water and no soil is leaking into the reservoir by using the cap. Self-irrigating pots can be used while you are on vacation or at work.

Self-Irrigating Materials

  • A PET bottle is different from any other container in that it was used to hold a beverage. Because they can be used to contain a beverage, PET bottles are safe for food and plant growth.
  • You can use a pocket knife such as a Buck or Gerber knife to help.
  • You can break the glass with your fingers and then pry it from the frame using a box cutter or a Stanley knife.
  • Tape a tuna can or chicken can with duct tape to keep pests away. The foul odor of decaying flesh can be detected within hours if the tape is not removed.
  • You can choose to use soil, coconut fiber, expanded clay pellets or any combination thereof.


  1. Cut a PET bottle in half using a knife or scissors.
  2. The water reservoir is located at the bottom.
  3. The substrate and plant will be kept in the top portion of the bottle. This includes the bottleneck.
  4. Use a knife to remove the cap.
  5. To reach the reservoir’s bottom and reach the roots at the top, cut a length from nylon rope.
  6. Once the bottle cap is closed, thread the wick through the hole until it is fully threaded.
  7. Place the cap back on the bottle.
  8. Although a cap is not necessary, it helps to prevent soil from seeping into the water tank.
  9. The container should be filled with your growing media (soil and coco fibers, expanded clay particles …).).
  10. Place the plant in the container and fill it with the remaining substrate.

The plant is now complete. Place the pot on top.

The reservoir should be filled at least halfway with water. Next, lift the pot and fill it up to the top. The substrate and wick are moistened by water from the above. After that, water will rise through capillary action.
