How to Make Compost Tea for Green Onion Fertilization

by

Compost tea is an excellent organic fertilizer that can boost the health and growth of your green onions. Making your own compost tea is simple and cost-effective. This guide will walk you through the steps to create nutrient-rich compost tea for your green onion garden.

What Is Compost Tea?

Compost tea is a liquid extract made by steeping compost in water. It contains beneficial microorganisms, nutrients, and organic matter that promote healthy plant growth. When used on green onions, compost tea can improve soil health and increase yields.

Materials Needed

  • Quality compost (preferably organic)
  • Water (non-chlorinated)
  • A breathable bag or cloth
  • A large bucket or container
  • An aeration source (air pump or manual aeration)
  • Optional: molasses or seaweed extract for additional nutrients

Steps to Make Compost Tea

1. Prepare the Compost: Use mature, high-quality compost. Place about one to two cups into a breathable bag or cloth.

2. Fill the Container: Fill a large bucket with about 5 gallons of water. If your tap water contains chlorine, let it sit overnight or use filtered water.

3. Steep the Compost: Submerge the compost-filled bag in the water. Stir gently to help release nutrients and microorganisms.

4. Aerate the Mixture: Use an air pump or manually stir the mixture every 12 hours. Aeration encourages the growth of beneficial microbes.

5. Add Optional Ingredients: For extra nutrients, add a tablespoon of molasses or seaweed extract to the mixture during steeping.

6. Steeping Duration: Let the mixture steep for 24 to 48 hours. The longer it steeps, the more nutrients and microbes are extracted.

Using Compost Tea on Green Onions

Strain the compost tea to remove solids. Use a watering can or sprayer to apply the tea directly to the base of your green onions. Apply every 1-2 weeks during the growing season for best results.
