Southwest Yard and Garden teaches viewers how to plant asparagus! First, in your garden you need to dig a trench that is about 8 inches deep. You should mix up some compost into this trench. Choose an asparagus that has a fern and make sure you choose a variety that is a male hybrid. These are more tolerant of other problems such as wilt. Simply, plant these 8 inches deep but do not cover them fully. Cover them gradually and cover it as it grows highly. Make sure your roots are laying horizontal when you plant them. A choice of your compost depends on what type of soil you have!
