- Once brewed, remove the bag and your compost tea is ready to use!
Aerated Method
The aerated method produces a more microbial-rich compost tea using an aquarium pump.
Materials Needed:
- A 5-gallon bucket
- A mesh bag or old pillowcase
- Quality compost
- Dechlorinated water
- An aquarium air pump with tubing and air stones
Steps to Brew:
- Fill the mesh bag with 2 cups of compost and place it in the bucket.
- Fill the bucket with water, allowing the bag to fully submerge.
- Attach the air stones to the pump and place them in the bucket, turning on the pump.
- Let it brew for 24 to 48 hours, keeping the pump running to aerate the solution.
- Remove the bag, and your compost tea is ready for use!
How to Use Compost Tea
Now that you have your compost tea brewed, it’s time to put it to good use! Here are some effective ways to apply it:
1. Foliar Spray
Using compost tea as a foliar spray can provide immediate nutrients to the leaves. Simply dilute the tea with equal parts water and spray onto the leaves during the cooler parts of the day to avoid scorching.
2. Soil Drench
Applying compost tea directly to the soil helps deliver nutrients to the plant roots. Use it liberally around the base of plants, avoiding stems to prevent rot.
3. Seed Soaking
You can also soak seeds in compost tea for a few hours before planting. This helps kickstart the germination process and provides an initial nutrient boost.

What is compost tea and why should I use it in my garden?
Compost tea is a nutrient-rich liquid fertilizer made by steeping compost in water. This process extracts beneficial microbes, nutrients, and organic matter from the compost, resulting in a potent brew that can be used to water plants, nourish soil, and promote healthy plant growth. By using compost tea, gardeners can improve the microbial diversity in their soil, leading to enhanced nutrient availability and improved plant health.
Using compost tea not only provides essential nutrients to plants but also helps in suppressing plant diseases and pests. The beneficial microorganisms in the tea can outcompete harmful pathogens, creating a healthier environment for your plants. Additionally, it can help improve soil structure and moisture retention, making it a valuable addition to any gardening regimen.
How do I make compost tea?
To make compost tea, start by gathering high-quality, well-aged compost. Use a non-treated, breathable bag to contain the compost, as this allows the nutrients to leach out while keeping the solids contained. Fill a bucket or container with water and place the bag of compost in it. Let it steep for 24 to 48 hours, stirring occasionally to aerate the mixture and allow for better microbial activity.
After steeping, remove the bag and use the liquid tea to water your plants, ideally within a couple of days to maximize freshness. Remember to dilute the compost tea with water if it appears too concentrated—typically a 1:1 ratio works well. With proper aeration and regular applications, your garden will benefit from the nutrients and microbes provided by this organic solution.
How often should I apply compost tea to my garden?
The frequency of applying compost tea can vary depending on your garden’s specific needs, the types of plants you are growing, and the overall health of your soil. Generally, applying compost tea every 2 to 4 weeks during the growing season is beneficial, as it provides a consistent supply of nutrients and beneficial microorganisms. However, keep an eye on your plants and adjust the frequency based on their growth and health.
In addition to regular applications, compost tea can also be particularly effective when used after heavy rain or extreme heat, as it can help replenish nutrients washed away in the soil or support plants during stress. Always observe your plants for signs of nutrient deficiency or growth issues and modify your compost tea application schedule accordingly.
Can I use compost tea on all types of plants?
Yes, compost tea is generally safe and beneficial for a wide variety of plants, including vegetables, flowers, and shrubs. The diverse nutrients and microorganisms present in the tea can support the healthy growth of many plant types. However, it’s always advisable to test the tea on a small area or a single plant first, especially for more sensitive species, to ensure they respond well to the treatment.
While most plants will thrive with compost tea, it’s also important to consider the specific nutrient needs of your plants. Some plants may require additional nutrients or specific amendments beyond what compost tea can offer, so it’s always good practice to observe how your plants respond and assess their overall health regularly.
What materials should I avoid when making compost tea?
When making compost tea, it’s essential to avoid using any sort of contaminated or non-organic materials, such as synthetic fertilizers, pesticides, or herbicides. These substances can harm beneficial microorganisms and introduce toxic elements into your tea, negatively affecting your plants and soil. Additionally, avoid using materials that are not fully decomposed or that may contain pathogens, such as diseased plant material or fresh animal manure.
It’s also important to refrain from using chemically treated water, as chlorine or other chemicals can kill beneficial organisms in the compost tea. Instead, consider using rainwater or tap water that has been left to sit for 24 hours to allow chlorine to dissipate, ensuring a healthier brew for your garden.
How should I store leftover compost tea?
Leftover compost tea should typically be used as soon as possible for maximum effectiveness. However, if you have extra tea, store it in a sealed, non-opaque container to protect it from sunlight, which can promote the growth of unwanted algae and diminish microbial diversity. Keeping the container in a cool, dark location will help preserve the tea’s nutrients and microorganisms for a short period.
It’s essential to use stored compost tea within a week for the best results; after this period, the beneficial microbes may begin to die off, and the nutrients can become less effective. If you notice an unpleasant smell or significant changes in appearance, it’s a sign that the tea has gone bad, and it’s best to discard it rather than risk harming your plants.
