How to Make Compost Tea


Composting is an essential practice for any prepper or gardener. It helps reduce waste, enriches the soil, and promotes healthy plant growth. While most people are familiar with traditional composting methods, there is another technique that can take your gardening to the next level – compost tea.

Compost tea is a liquid fertilizer made from soaking compost in water. It is rich in essential nutrients and beneficial microorganisms that can significantly improve the health and productivity of your plants. In this article, we will guide you through the process of making compost tea and highlight its benefits.

What You’ll Need

To make compost tea, you will need the following materials:

1. Compost: Use high-quality compost that is rich in organic matter and has decomposed fully.

2. Water: Tap water is suitable for making compost tea, but if you have access to rainwater, it’s even better.

3. A container: Choose a container large enough to hold your compost and water while still leaving enough space for aeration.

4. Aeration device: You will need an aeration device to add oxygen to the tea. A simple aquarium pump and air stone will work just fine.

5. Optional additives: You can add additional ingredients to boost the nutritional content of your compost tea. Some popular choices include molasses, kelp meal, and worm castings.

The Steps to Make Compost Tea

Now that you have gathered all the necessary materials, let’s go through the step-by-step process of making compost tea:

1. Fill your container: Fill your container about three-quarters full with water. If possible, use rainwater as it is chlorine-free and better for the microorganisms in the compost.

2. Add compost: Place the compost in a mesh bag or a fine-meshed basket and submerge it in the water. Make sure the compost is fully submerged but not packed too tightly.

3. Start aeration: Attach the aquarium pump to the air stone and place it in the container. Turn on the pump to start the aeration process. Aeration helps increase oxygen levels in the tea, promoting the growth of beneficial microorganisms.

4. Let it steep: Allow the compost tea to steep for 24 to 48 hours. During this time, the beneficial microorganisms will multiply and release nutrients into the water.

5. Optional additives: If desired, you can add additional ingredients such as molasses, kelp meal, or worm castings to enhance the nutritional content of the tea. These additives provide extra minerals and help feed the beneficial bacteria in the compost.

6. Strain the tea: After the steeping period, remove the compost from the water. Strain the tea to remove any larger particles or debris. You can use a mesh screen or a cheesecloth for this purpose.

7. Apply the compost tea: Dilute the compost tea by adding water until it resembles the color of weak tea. Use a watering can or a sprayer to apply the compost tea directly to the soil around your plants. Avoid drenching the foliage to prevent the spread of diseases.

The Benefits of Compost Tea

Now that you know how to make compost tea, let’s explore some of its benefits:

1. Nutrient-rich: Compost tea is a potent fertilizer that provides a wide range of essential nutrients for plants. It contains nitrogen, phosphorus, potassium, and micronutrients necessary for healthy growth.

2. Soil enrichment: Applying compost tea to the soil helps improve its structure and fertility. It increases the organic matter content, enhances water retention, and promotes overall soil health.

3. Disease suppression: Compost tea contains beneficial microorganisms that can protect plants against harmful pathogens. When applied as a foliar spray, it forms a protective barrier on the leaves, reducing the risk of diseases.

4. Improved plant growth: Regular use of compost tea can enhance plant growth and vigor. It stimulates root development, increases nutrient uptake, and improves overall plant health, leading to higher yields.

5. Sustainability: Making compost tea is an eco-friendly way to recycle organic waste and reduce reliance on chemical fertilizers. It promotes sustainable gardening practices while minimizing environmental impact.

My 2 Cents

Compost tea is a fantastic addition to any gardener’s toolkit. It is an inexpensive and natural way to fertilize your plants, promote soil health, and protect against diseases. Remember to use high-quality compost and follow the steps outlined in this article for the best results.

Experiment with different additives to tailor the compost tea to the specific needs of your plants. From molasses to kelp meal, there are plenty of options to explore. Just make sure to maintain proper aeration during the brewing process to maximize the growth of beneficial microorganisms.

By incorporating compost tea into your gardening routine, you can harness the power of nature to achieve lush, thriving gardens. Give it a try, and watch your plants flourish like never before!
