Tips for Using Compost Tea on Plants: An Essential Guide

Compost Tea

If you are into gardening, then you must know about compost tea. It is a liquid fertilizer that is made by steeping compost in water. The process extracts beneficial microorganisms, enzymes, and nutrients from the compost, creating a potent solution that can nourish your plants.

Compost tea is not only easy to make but also inexpensive compared to other fertilizers. Plus, it is an eco-friendly alternative to synthetic fertilizers that can harm the environment.

Why Use Compost Tea?

Compost tea has several benefits over other fertilizers. Firstly, it improves soil quality by increasing microbial activity in the soil. The microorganisms in the tea break down organic matter, making it easier for plants to absorb nutrients. Secondly, it enhances plant growth and yields by providing essential nutrients such as nitrogen, phosphorus, and potassium. Lastly, it helps to prevent diseases by boosting the plants' immune system.

Now that you know why compost tea is great for your plants, let's dive into some tips on how to use it effectively.

Tips for Using Compost Tea on Plants

1. Choose Quality Compost

The first step to making good compost tea is to choose high-quality compost. Avoid using compost that smells bad or has visible signs of mold. Instead, opt for compost that is dark, crumbly, and has a sweet earthy smell.

Tip:

You can make your own compost at home using kitchen scraps, grass clippings, leaves, and other organic matter.

2. Use the Right Water

The quality of water you use to make compost tea is crucial. Avoid using chlorinated water or water that has been treated with chemicals. Instead, use rainwater, well water, or distilled water.

Tip:

If you have to use tap water, let it sit overnight to allow chlorine to evaporate.

3. Brew Compost Tea Properly

Brewing compost tea properly is essential to get the best results. The brewing process can take anywhere from 24 hours to a week, depending on the recipe you are using. Follow the instructions carefully and avoid over-brewing, as it can harm your plants.

Tip:

You can add molasses or sugar to the mixture to feed the microorganisms and speed up the brewing process.

4. Apply Compost Tea at the Right Time

Timing is crucial when it comes to applying compost tea. Apply it when the plants are actively growing, preferably in the morning or evening when the temperature is cool. Avoid applying it during hot weather or when the soil is dry.

Tip:

Apply compost tea every two to four weeks during the growing season for optimal results.

5. Dilute Compost Tea Before Applying

Compost tea is potent, and using it undiluted can harm your plants. Always dilute it with water before applying it. A good rule of thumb is to dilute it 1:10 (one part compost tea to ten parts water).

Tip:

You can use a watering can or spray bottle to apply compost tea to your plants.

6. Use Compost Tea as a Foliar Spray

Compost tea can also be used as a foliar spray. A foliar spray is when you apply the liquid directly to the leaves of the plants. This method allows the plants to absorb nutrients more quickly.

Tip:

Use a fine mist sprayer to apply compost tea as a foliar spray.

7. Store Compost Tea Properly

Storing compost tea properly will help to maintain its potency. Always store it in an airtight container and keep it in a cool, dark place. Use it within a week of brewing, or it may lose its effectiveness.

Tip:

Label your container with the date and recipe used for brewing.

8. Test Your Soil Regularly

Testing your soil regularly will help you determine if your plants are getting the right nutrients. You can test your soil using a home testing kit or by sending a sample to a lab.

Tip:

Adjust the amount of compost tea you use based on the results of your soil test.

9. Be Patient

Using compost tea is a long-term solution for plant care. It takes time for the microorganisms in the tea to establish themselves in the soil and working their magic. Be patient and consistent, and you will see the results over time.

Tip:

Keep a record of your plants' growth and health to monitor the effectiveness of compost tea.

10. Use Compost Tea in Combination with Other Fertilizers

While compost tea is an excellent fertilizer, it is not a complete fertilizer. It does not contain all the essential nutrients that plants need. Therefore, it is best to use compost tea in combination with other fertilizers, such as fish emuon or bone meal.

Tip:

Consult with a gardening expert to determine the best combination of fertilizers for your plants.

11. Use Compost Tea on Indoor Plants

Compost tea is not just for outdoor plants. You can also use it on indoor plants to improve their health and growth. Apply it using a watering can or spray bottle.

Tip:

Use a fine mist sprayer to apply compost tea as a foliar spray for indoor plants.

12. Use Compost Tea on Seedlings

Compost tea is an excellent fertilizer for seedlings. It provides the nutrients they need to grow strong and healthy. Apply it using a watering can or spray bottle.

Tip:

Dilute compost tea to half strength when using it on seedlings.

13. Use Compost Tea to Revive Sick Plants

Compost tea can help revive sick plants by boosting their immune system and providing essential nutrients. Apply it using a watering can or spray bottle.

Tip:

Apply compost tea every week until the plant shows signs of improvement.

14. Use Compost Tea on Lawns

Compost tea is an excellent fertilizer for lawns. It improves soil quality, promotes root growth, and enhances the overall health of the grass. Apply it using a hose-end sprayer or a backpack sprayer.

Tip:

Apply compost tea in the morning or evening when the temperature is cool.

15. Use Compost Tea to Attract Beneficial Insects

Compost tea can attract beneficial insects to your garden, such as ladybugs, lacewings, and hoverflies. These insects prey on harmful pests, such as aphids and mites, helping to keep your plants healthy.

Tip:

Apply compost tea in the evening to avoid harming bees and other pollinators.
