How long will harvested castings keep in an open tub?
I am far off from harvesting castings from my week old worm factory but have been trying to read up on how I want to proceed.
I shouldn't have any problem separating out the worms but what about unhatched cocoons? I was thinking about dumping the harvested castings into a separate tub and let them hatch naturally. I could then pull those new worms out after they hatch and use the castings without loosing any worms.
If I was to do this ...
(1) How long would I have to wait until the last (or most of the last) of the cocoons have hatched? I'd hate to wait so long that the first batch start laying more cocoons.
(2) How long will the beneficial organisms in the castings remain viable in an open tub for use on my lawn, trees and flowers? Would you spray it with water to keep it from drying out?
