If you live in a very warm climate a worm heap would be more trouble than it's worth. They need to be kept moist at all times, if they start to dry out the worms just burrow back down into the earth where they came from. Living in the uk I don't need to worry about the moist bit, our weather sorts that out!
The next most important part is to keep them well fed, otherwise they will burrow back down into the earth just like if the heap dries out. I find old newspapers, food scraps, grass and plant cuttings keep them from burrowing away. With Halloween just passing I threw on the kids (and mine
) pumpkins all chopped up.And as long as it's moist and well fed every shovel full of gunk out of it will be plastered in worms. During winter I stop feeding and they all disappear, until the next spring when I start feeding again. And the worms come a running.
