Another thing I'm going to do this year is buy some nightcrawlers and
set them loose into the garden soil. Everything helps.
Yes the mushroom compost would be rich and make a good tea.
I suspect that is the worm here, they are big and 6 or 8 inches long, I may have lost them now, but they were here in the past.
I am only 25 miles from Lake Mohave, so there are fish in the area and the little store here in the valley, 30 years ago sold nightcrawlers to the fishermen.
