Asparagus

Asparagus is the twenty-year commitment, crowns planted once in April and spears cut every spring from year three on. Six weeks of April-to-June picking pays for eleven months of leaving it alone.

Growing

Plant crowns in April in a permanent, weed-free bed with real depth; this is a decades-long tenancy, so fix the soil before, not after. Cut nothing the first year, take a light two weeks the second, and harvest in full from year three, snapping spears at soil level from April into June. When spear diameter drops to pencil size, stop cutting and let the ferns rise; from July through October the ferns feed the crowns for next spring, so they stand until fully brown. Cut the dead ferns down in late fall and top-dress the bed with compost. All it asks in between is sun, drainage, and weeding. Water it like any new planting for its first two summers; established beds run on rain except in real drought.

Varieties

Millennium has become the Northeast planting of choice: all-male, cold-hardy, productive for decades. Purple Passion adds sweeter spears worth eating raw.

Pests

The common asparagus beetle overwinters in old fern debris and chews spring spears; sanitation, meaning last year's ferns actually removed, is half the control. Finger patrols do the rest, though the beetles drop the moment they sense a shadow. The gray, slow larvae wipe off the summer ferns easily.

In the kitchen

Steamed or seared within the hour, because asparagus loses sweetness off the stalk faster than nearly anything. The skinny late spears go raw, shaved, with lemon.
