Hmmm... you've got me thinkin! I've never done worms yet but that might be a good way to go! Our garden project for the spring is to convert our in-ground garden to raised beds. We have really bad clay soil so thought we'd try the square foot gardening method. I'm hoping our yields will improve over last year and that when we get ready to sell our property, it will be a selling feature to have raised beds in place...Beekissed said:I'm also planning to build in some soil boxes in this greenhouse and keep some worms going in the soil. How does it sound to plant my lettuces right in the worm boxes? How much better can one get in the way of soil fertility than to have your food growing right on top of your worms? Any trimmed leaves and salad scraps could get replaced right under the mulch layer to feed the worms.
