Asparagus
Asparagus is a permanent spring vegetable grown from crowns for tender spears that return year after year once established. It takes patience to build a productive bed, but few crops offer the same sense of early-season reward from a long-lived planting.

Care tips
Keep asparagus beds meticulously weed free so shallow crowns are not crowded, and do not rush harvesting from newly planted crowns before they have built strength. After picking season ends, let the ferny top growth mature fully so the plant can recharge for next year.
Common pests
Asparagus beetle, slugs on young spears, rust, crown rot.
