Asparagus

The secret to asparagus longevity is soil prep and ditch-digging. Plants will provide for decades if done correctly. Dig a trench 8 to 10" deep and 12" wide. Mix removed soil with compost, aged manure, and superphosphate. Fill trench with 3/4 of mixture. Spread asparagus roots out over mix and cover with 2-3" of remaining mix. Water in well. Resist harvest until the 2nd season. Cut shoots 1/2" below ground when they are as thick as your little finger.
