Vegetables· Asparagus officinalis
Asparagus is a perennial vegetable that can produce spears for 15-20 years from a single planting. It requires patience, as the first full harvest is not taken until the third year, but well-maintained beds are among the most profitable long-term vegetable investments.

Do not harvest any spears in the first year and only lightly for 2 weeks in the second year; this builds root reserves for decades of production.
End harvest when spear diameter drops below pencil-width and allow ferns to grow all summer to recharge the crown for next spring.
Apply 5-10 cm of mulch annually to suppress weeds and maintain soil moisture; asparagus does not compete well with weeds.
