Love that iguana story!
I got my tiny dog sort of like that. Started looking at Newfoundlands. Next thing you know, the pomeranian was approved.
I don't do those worm composts. I just have a cage and throw stuff in it. It needs to be turned over once in a while, and it should be watered - I just hope for rain, I'm lazy.
But in spring, I take a rake and separate the chunks from what's turned to dirt. The dirt is dark as coffee grounds, and that goes on whatever bed needs it. Last year it went to the zebra grass. Some times it goes to the veggies or the roses.
The stuff that didn't break down goes back in the cage. Fruit and veggies, lawn clippings, dirt from old potted plants, all that goes in. My yard was hard clay when I moved here. Now the beds are all black soil, you can sink a spade to the handle.
I hope the people who buy this house decide they like gardening. I put a lot into that yard.
