Worm castings can be mixed into planting beds or used as a top dressing. For every square foot of planting area I try to use at least one cup of castings. Sometimes I don’t have enough on hand – a little is better than nothing. Here’s how I make worm casting tea: Worm tea is easy to make. It doesn’t stink and fortifies the soil with water soluble nutrients and organic matter that makes microorganisms happy and productive. Find an old crew sock and fill it with worm castings, secure the end and use it like a tea bag in a big bucket of water. Two cups of castings works great in 2 gallons of water. That’s the size of a large watering can. Add the sock directly to the watering can. Let it sit for 1-3 days, stirring well once a day, and use that solution to water your plants. For larger containers and beds, I like to water the garden first before applying the compost tea to ensure nutrients can travel easily. If I’m not in the mood to bag up the castings, I simply put the stuff in the bucket and add water. I dump everything out, castings and all. If you’re in a hurry or can’t find a pail, put some worm castings in a bag with a small hole in the bottom. Add water and drizzle the liquid around your garden. Works for me!
