How to Make a Good Compost Tea Ratio


Experienced gardeners with thriving gardens are usually familiar with compost and the benefits of amending the soil with organic materials. A compost bin with organic ingredients decomposing is the mark of a gardener who knows how to put yard and household waste to good use. Brewing and making compost tea for use in the garden is another effective way to give plants the nutrients they need to grow strong. Make a good compost tea ratio to create beneficial tea for the garden.

Step 1

Fill one bucket with cool water and let the water sit for at least eight hours to allow the chlorine to dissipate. Chlorine in the water may affect the bacteria that must form in the compost tea.

Step 2

Place one part aged compost in the other bucket. Cover the compost with between five and eight parts water. Use less water for a stronger compost tea and more water for a weaker compost tea.

Step 3

Cover the bucket and allow the tea to sit for between three days and three weeks to ferment. Optimal fermenting temperature is between 59 F and 68 F.

Step 4

Cover the top of the second bucket with cheesecloth and pour the compost tea through the cheesecloth into the bucket after the fermenting period elapses, to strain the tea.

Step 5

Apply the compost tea to plant foliage or plant roots as soon as possible after straining it. Compost tea contains the most nutrients when it is fresh.
