Avoid all these problems to produce straight, marketable spears. It will increase vigor and decrease risk of infection by fusarium. Apply water, at least for the first 2 years, if possible. Female plants are less productive and have a shorter life because the plant's energy is allocated to seed production in the fall.

Summary Choose a planting site in full sun that has not been in asparagus previously.
