Greenhouse: Over the weekend and yesterday we finished preparing the soil. The chickens have been in it since mid July. We put about more than a dozen wheelbarrows of old donkey dung as well as about 9 barrows of seagrass. After removing the chickens, we dug out paths about 12" wide with beds 30" wide. The raised beds are now covered with cardboard weighted with logs in the paths. I planted lettuce and spinach I cut holes in the cardboard and planted the seeds mixed with old donkey dung.
