Getting the mix right.
Plants that flower and fruit are hungry, so give them more. Everything else does great with less. And since castings can't burn roots, erring on the high side is fine.

Use compost tea fresh
Compost tea is alive, so it's best the day it's brewed. Spray it on leaves or pour it around the roots.
Keep your castings alive
They're full of living microbes. Store your bag somewhere cool and out of direct sun, keep it slightly moist, and don't seal it airtight.
When in doubt, add more
There's no such thing as too much. A little goes a long way, but more never hurts.
