4. Improves Soil Structure
5. Eco-Friendly Solution
6. Cost-Effective
7. Easy to Make

Overall, the benefits of using compost tea are so numerous, it’s silly not to give it a try.

Will Full Strength Compost Tea Burn My Plants?

Compost tea is pretty light and shouldn’t burn your plants. Here are a couple of tips to ensure you use your tea safely.

• Don’t spray foliage during midday when your plants are in direct sunlight.
• Test a small patch of your garden, or just one plant to be sure your tea isn’t too strong.
• You can always dilute your compost tea by adding more water.

Is Making Your Own Compost Tea Complicated?

No, making your own compost tea is not complicated. Basically, use broken down organic matter. Let it soak in some water, and stir it occasionally. 

What’s in Compost Tea?

Compost tea is a liquid solution made from compost, which is used as a natural fertilizer and soil amendment in gardening and agriculture. The main components of compost tea are:

1. Compost: The base material, which provides a rich source of beneficial microorganisms, nutrients, and organic matter. This can be made from a variety of organic materials like vegetable scraps, leaves, and manure.
2. Water: Used to extract the soluble nutrients and microorganisms from the compost. Typically, chlorine-free water is preferred to avoid killing beneficial microorganisms.
3. Aeration: Oxygen is introduced into the solution through continuous agitation or by using an air pump or stirring by hand. This encourages the growth of aerobic microorganisms, which are beneficial for plants and soil health.
4. Molasses or other sugar sources (optional): Sometimes added to provide an additional food source for the microorganisms, helping them to multiply more rapidly.
5. Fish emulsion, kelp, or other nutrient boosters (optional): These can be added to enhance the nutrient profile of the compost tea, providing additional minerals and nutrients for plant growth.

Is Compost Tea Better Than Compost?

Compost and compost tea complement each other rather than compete. For the best results, you can use both: compost to build and maintain soil health over the long term, and compost tea for quick, targeted nutrient delivery and microbial inoculation.

Where to Source Compost

We have no shortage of posts on the topic of making your own compost right here. Whether you choose to keep an official hot compost bin or your own compost pile that you’re perpetually adding to for a cold system, using what you have saves money, time, and resources.

You can purchase bagged organic compost from your local farm store as well. 

Using Worm Castings in Your Compost Tea

Using worm castings in compost tea, making a worm tea, enhances the tea’s nutrient profile and microbial diversity, as worm castings are rich in beneficial microorganisms and essential nutrients. This can improve plant health and boost soil fertility by providing an immediate source of nutrients and beneficial bacteria. 

You can also produce your own worm castings by creating mini worm farms to work with your composting systems at home. This is absolutely on my list of goals to accomplish this year.

To use worm castings in compost tea, mix 1-2 cups of worm castings per gallon of chlorine-free water. Aerate the mixture with an air pump for 24-48 hours, then apply the tea as a soil drench or foliar spray for optimal results.

How Long Does Compost Tea Last?

Compost tea has a relatively short shelf life, typically lasting about 24 to 48 hours after brewing. The viability of the beneficial microorganisms in the tea diminishes rapidly beyond this period due to a lack of oxygen and nutrients. 

For best results, compost tea should be applied to plants or soil immediately after brewing to ensure the highest concentration of active microbes and nutrients.

If you’ve forgotten the tea, you can revive the life of the brew by feeding it with sugars and more plant life. Don’t forget to stir it a couple of times a day if you don’t have a pump.

How Long Does It Take to Brew Compost Tea?

Brewing compost tea typically takes about 24 to 48 hours. During this time, the compost is steeped in aerated water, which helps to multiply the beneficial microorganisms. It’s important to maintain continuous aeration throughout the brewing process to keep the microbes alive and active.

Since we’re on the subject of how to make compost tea WITHOUT A PUMP, you’ll have to provide aeration by stirring it yourself. It’s going to take longer than the typical day or two this way.

Your compost tea will brew faster in warmer temperatures too. The microbial life that provides the soil food web doesn’t love to multiply in cold temperatures.

How Long Can I Let My Compost Tea Brew?

When your tea stops producing bubbles, it’s past the point of finished. The bubbles produced are a sign of live, active compost tea. Brewing compost tea beyond this period can lead to a decline in the population of beneficial microorganisms due to nutrient depletion and possible buildup of harmful anaerobic bacteria (bad bacteria) if the aeration is insufficient.

Is Adding Molasses To Compost Tea Necessary?

Adding molasses to compost tea is a great way to add a food source for beneficial microorganisms, encouraging their rapid growth and multiplication. The sugars in molasses provide essential energy, boosting the microbial activity and diversity in the tea. This increased microbial population can enhance nutrient availability and disease suppression when applied to plants. 

Typically, about 1-2 tablespoons of unsulfured molasses per gallon of water is added to the brewing compost tea mixture. Using molasses helps create a richer, more potent compost tea that supports healthier, more resilient plants and healthy soil.

Other ways to feed the beneficial microbes in your tea are to add plain sugar, dried potato flakes, or other carbohydrates to your compost tea.

How Do I Know When My is Compost Tea Ready?

If you’re stirring your tea frequently, your tea should be ready in 24-48 hours. Make sure that you use your tea before it shows signs of anaerobic conditions.

How to Make Compost Tea Without a Pump

Making compost tea without a pump is simple and effective if done correctly. Here are the steps:

Supplies Needed:

• High-quality compost (preferably well-matured and rich in organic matter)
• Non-chlorinated water (rainwater, distilled, or tap water that has been left to sit for 24 hours to allow chlorine to dissipate)
• A large container or bucket (5-gallon size works well)
• Unsulfured molasses (optional, for microbial food)
• A stirring stick or ladle

Instructions:

1. Add the Water:

Fill your container with non-chlorinated water. If using tap water, let it sit uncovered for 24 hours to evaporate the chlorine, which can harm beneficial microorganisms.

2. Add Compost:

Place 1-2 cups of compost into the water for every gallon of water used. You can use a porous bag (like a cheesecloth or old pillowcase) to contain the compost, making it easier to remove later, or you can add it directly to the water and strain it later.

3. Add Molasses (Optional):

Add 1-2 tablespoons of unsulfured molasses per gallon of water. This provides additional food for the good microbes, helping them to multiply more rapidly.

4. Stir the Mixture:

Stir the mixture vigorously several times a day to introduce oxygen. This mimics the aeration provided by a pump and helps keep the compost tea aerobic, promoting the growth of beneficial microbes.

5. Brew Time:

Allow the mixture to steep for 24 to 48 hours. Continue stirring periodically throughout this period.

If You Have a Pump

Now, I don’t want you to think that you need a pump, hence the “without a pump” part of the title here. However, if you happen to have a pump, you’ll save yourself from forgetting to stir, aerating your tea. You could pick up a cheap aquarium pump system with air stones attached at your local fish store or check Amazon.

Just drop the bottom of the air hose into the bucket and turn it on. To keep the air stones from becoming clogged, you may want to make a tea bag of sorts for your compost. A sock or pantyhose work well for this job. Fill it with compost, and tie the top, dropping it into the bucket of water.

How to Use Your Compost Tea

After brewing, strain the compost tea through a fine mesh or cheesecloth to remove solid particles. The tea is now ready to be used as a soil drench or foliar spray. Apply it immediately to your garden beds for the best results.

1. Drench the Soil

Pour the compost tea directly onto the soil around the base of your plants so that your plant roots are drenched. You can use a watering can, a garden sprayer, or any container that allows you to apply the tea evenly. 

Ensure that the tea thoroughly soaks into the root zone of your plants. For larger plants, apply enough tea to saturate the soil several inches deep around the base.

2. Spray Your Plants

Using compost tea as a foliar spray allows plants to absorb nutrients directly through their leaves, providing a quick nutrient boost and enhancing plant health. It helps to increase the population of beneficial microorganisms on the leaf surface, which can improve disease resistance and overall plant vitality. For best results, apply the compost tea as a foliar spray early in the morning or late in the afternoon to avoid the intense midday sun.

How Frequently Should I Use Compost Tea?

Apply compost tea every two to four weeks during the growing season. This can be adjusted based on plant needs and soil health.
