Answer: Dig a trench 8 inches deep and wide enough to accommodate the outspread roots (about 10 inches), then space the asparagus 18 inches apart. Cover the roots with two inches of soil, and continue to fill in the trench as shoots grow. Be sure never to bury the green shoots completely. The trench can usually be filled by the end of the first growing season, but if not, simply continue to work on it the second year.
