Mix 2 tsp. of yeast in a bowl with 1 tsp. of flour, 2 tsp. of sugar and 2 cups of warm water. Wait for the yeast to stop foaming. Add 2 tbsp. of cornstarch and 1 tbsp. of flour to the mixture and allow it to sit for two hours.
Mix the yeast mixture in a bucket with 1 lb. of fruit scraps (no citrus), 5 tbsp. of cornstarch, a handful of finished compost and 5 tbsp. of blood or fish meal. Fill the bucket with warm water. You have now made compost tea.
Place the bucket outside in a sunny spot. Mix the compost tea daily to aerate it.
Let the compost tea sit for one week, then pour it in your compost bin or over poor soil.
