Some folks think it's strange that I should go from writing about houseplants to compost, but at my house they are very much connected!
Example: One of the ways I'm satisfying my gardening addiction during the gotta-wait days of late winter is by making vermicompost. The bin I started in a cat litter jug two months ago is working nicely now, so I set up another one this week.
The vermicompost I'll harvest in a couple of months will be rich in plant nutrients and humic acids, so it will be a stellar fertilizer for houseplants. Right now I'm using a batch I made and stored last fall to get a balky begonia in a blooming mood. And a light sprinkling goes into the soil I'm using to grow veggie seedlings, too!
The bins will bear more than great compost, because well-fed captive earthworms produce cocoons as well as castings. I borrow my worms from the garden, then return them after they've finished a tour of bin duty. It's a cushy job - no cold, no drenching rains, and all the food you can eat. Makes me wonder if I'm working for the worms, or are they working for me?
