Transform Your Garden with Homemade Compost Tea

Compost tea is an excellent fertilizer for plants that you can make at home using compost and water. The resulting tea is rich in nutrients and beneficial microorganisms that help promote healthy plant growth. In this article, we will discuss how to make and use it.

What is Compost Tea?

Compost tea is a liquid fertilizer made by steeping compost in water. As the compost decomposes, it releases nutrients and beneficial microorganisms into the water. The resulting tea can be used to feed plants directly or as a foliar spray.

How to Make Compost Tea?

To make it, you will need the following ingredients and equipment:


  • High-quality compost
  • Water


  • A large bucket or container
  • A stirring device
  • A piece of cloth or cheesecloth
  • An optional air pump and air stone


  1. Fill a large bucket or container with water. If possible, use non-chlorinated water, as chlorine can kill beneficial microorganisms in the compost tea.
  2. Add a few shovelfuls of high-quality compost to the water. The compost should be fully decomposed and free of pathogens.
  3. Stir the mixture well to distribute the compost throughout the water.
  4. Cover the container with a piece of cloth or cheesecloth to keep out debris and pests.
  5. If you have an air pump and air stone, you can add them to the container to provide oxygen for the microorganisms in the tea. This will help promote their growth and activity.
  6. Let the compost tea steep for 24-48 hours, stirring occasionally.
  7. After 24-48 hours, strain the compost tea through a piece of cloth or cheesecloth to remove any solids.
  8. Use it immediately, or store it in a covered container in a cool, dark place for up to one week.

How to Use Compost Tea?

Compost tea can be used in a variety of ways to fertilize your plants. Here are some of the most common methods:

  1. Watering: You can use it to water your plants directly. Simply pour the tea onto the soil around your plants, making sure to saturate the root zone.
  2. Foliar Spray: You can also use it as a foliar spray. This involves spraying the tea directly onto the leaves of your plants. This method can help promote healthy growth and deter pests and diseases.
  3. Soil Drench: For larger plants, you can use a soil drench to apply it directly to the roots. To do this, mix it with water and pour it directly onto the soil around the plant.

Tips for Using Compost Tea Safely and Effectively

Here are some tips for using compost tea safely and effectively in your garden:

  1. Use high-quality compost that has been fully decomposed to avoid introducing harmful pathogens into your garden.
  2. Use clean, non-chlorinated water to avoid killing beneficial microorganisms in the tea.
  3. Use it within 24 hours of brewing to avoid the growth of harmful bacteria.
  4. Do not apply it to plants that are already stressed or diseased, as this can further damage them.
  5. Test it on a small area of your plants before using it on your entire garden. This will help you identify any potential issues before they become widespread.

In conclusion, compost tea is an easy and effective way to provide your plants with the nutrients they need to thrive. By following these tips, you can use it safely and effectively in your garden.
