I have used worm compost several ways this summer.
I have planted successive crops such as lettuce in my raised beds. If I’m replanting the whole bed, I will mix 1 cup of worm compost into each square foot of soil. If I’m just planting a few plants, then I will mix 1/2 to 1 cup in the backfill.
If you have an established bed that needs some nutrients, you can just “top dress” by adding a small shovel full of worm compost around the base of each plant.
If want want to make a liquid fertilizer then you can use the worm compost to make a “worm tea” – to water your plants.
