Making Organic Compost Tea
Making organic compost tea is a straightforward process, and there are two methods to choose from: aerated and non-aerated.
The aerated method involves introducing oxygen into the liquid, which can be done using an aerator or a bubbler. This process can take anywhere from 12 to 24 hours.
The non-aerated method, on the other hand, relies on the natural process of decomposition without the introduction of oxygen. This method is often simpler, but may take longer to produce results.
Both methods require a good quality compost to be used as the base, and the liquid should be strained before use to remove any solids.
Non-Aerated Compost Tea Method
The non-aerated compost tea method is a simple and effective way to create compost tea at home. It requires just a few ingredients: compost, clean tap water, a mesh bag, and a bucket.
To make non-aerated compost tea, you'll need 1 gallon of non-chlorinated water and 1 1/2 cups of finished compost.
The process is straightforward: put the finished compost into a mesh bag, then place the mesh bag into a 5-gallon bucket. Fill the bucket with non-chlorinated water and place it in a cool, dark place.
Stir the mixture every day for one week to allow the beneficial microbes to break down the compost and create a nutrient-rich tea.
The tea should be administered to your plants about once a week. It can be applied in two ways: either poured into the soil around the base of a plant or sprayed onto the leaves as a foliar spray.
Here are the ingredients and directions you'll need to follow:
- 1 gallon non-chlorinated water
- 1 1/2 cups finished compost
- 5-gallon bucket
- Mesh bag
The benefits of using non-aerated compost tea include suppressed diseases and pests when sprayed onto the leaves, and increased plant growth when poured into the soil.

Aerated Compost Tea Method
Aerated compost tea is a quicker way to make compost tea, ready in about 48 hours after brewing starts.
To make aerated compost tea, you'll need an aquarium bubbler, which adds dissolved oxygen to the solution, allowing microbes to flourish.
The bubbler requires more equipment than the non-aerated method, but it's worth it for the faster results.
However, the aerated method has a downside: the microbial community can crash if the oxygen source is discontinued.
You'll need to use the aerated tea right away after turning off the bubbler to minimize the risk of a microbial community crash.
There's no guarantee that a higher microbial count will lead to a better garden, so don't rely solely on the aerated method.
Tips for Success
To ensure your compost tea is effective and safe for your plants, follow these tips for success.
Use high-quality, mature compost to brew your compost tea, as this will provide a nutrient-rich tea for your plants.
Avoid over-brewing, as this can result in a foul-smelling tea that's best discarded and brewed again from scratch.
Apply your compost tea early in the morning or late in the afternoon to prevent leaf burn, which can be detrimental to your plants' health.
Essential Materials and Equipment
Organic compost tea is a game-changer for gardeners, and to make it, you'll need some essential materials and equipment.
A high-quality compost is the foundation of great compost tea, so make sure to use organic compost that's rich in nutrients and free of contaminants.
Dechlorinated water is best for brewing compost tea, as chlorine can harm beneficial microbes.
A 5-gallon bucket is an ideal size for brewing compost tea, making it easy to mix and aerate the liquid.
An aquarium pump and air stones work well to oxygenate the tea, which helps to activate the beneficial microbes.
If you want to give your compost tea an extra boost, you can add unsulfured molasses or kelp meal, but these are optional.
Here's a quick rundown of the essential materials you'll need:
- High-quality compost
- Dechlorinated water
- A 5-gallon bucket
- Aquarium pump and air stones
Using and Maintaining Compost Tea
Strain the liquid through a fine mesh or cheesecloth to remove solids after brewing is complete.
This step is crucial to remove any remaining solids that could clog your spray bottle or drench equipment.
Use the tea immediately as a soil drench or foliar spray for best results.
The longer you wait, the more beneficial microbes will die off, reducing the tea's effectiveness.
Strain the liquid through a fine mesh or cheesecloth to remove solids after brewing is complete, and then use it right away to get the most out of your compost tea.

Compost Tea for Growers
Eric Fisher, a permaculture orchardist, has written extensively on the importance of nutrients and their cycles in soil. He emphasizes that understanding soil and nutrients is crucial for managing it properly.
A compost tea is a liquid solution made by steeping compost in water, which can remedy many different deficits in the soil. Eric provides recipes for a wide range of compost teas in his book.
Eric's approach is to empower growers to diagnose plant disease and pest problems on their own, and then create the right remedy for the problem. This approach can save growers money and encourage others to adopt organic practices.
To create compost teas, growers can use the plants growing around them, taking advantage of aerobic and anaerobic processes. This can be a simple and effective way to promote healthy ecosystems.
Eric's book includes full-color photographs and illustrations throughout, making it a valuable resource for growers.
