Preparing greenhouse beds for spring planting

Sometimes the greenhouse is the only place where a person can get much gardening done in the winter, especially when the ground outside the greenhouse is frozen. One thing that I should add to what I said in this video is that it is real important to keep some of the rough and woody materials from the old dirt and from the new manure that you are mixing in and resist the temptation to weed that stuff out or make the ground more smooth. The rough stuff–stems, root pieces, twigs, wood chips, etc.–help to keep the soil loose and provide feed for the helpful worms, insects and micro-critters who keep the soil in good health.
