Worm Castings
This stuff
will make your plants grow like crazy. You can sprinkle it around the
top of the pot and water it in.
Mix it up
with potting soil to boost growth of your plants or make "worm
tea" by soaking the castings in pure water like a tea bag. An
old panty hose or sock will work. This makes an excellent liquid
fertilizer for all your needs. Steep overnight in a quart or gallon
container, stir occasionally. Then continue to use until water is
clear. Then the castings can still be used as a fertilizer as well.
You cannot
harm plants by adding too much, unlike commercial fertilizer.
Castings are
very light, a gallon bag will weigh about 5 lbs.
