Plant These Once and Cut Your Own Asparagus for Twenty Years

From seed, asparagus takes four years to first real harvest; two-year crowns cut that to two. All-male Jersey hybrids put energy into spears instead of seedlings - no volunteer thicket - and ten crowns become a family's spring supply. This is the one bed where buying age is unambiguously worth it.

Plant once, correctly: full sun, and nowhere the bed will be in the way for 20 years.

Crowns plant in a trench over a ridge of enriched soil, and what goes under them is what those roots eat for years - composted manure worked into the trench floor is the classic and correct extravagance. Asparagus is a heavy feeder on a twenty-year lease; furnish the apartment before the tenant arrives.

Composted, never fresh - fresh manure burns crowns and breeds weeds.

Snapping spears works, but the forked asparagus knife cuts an inch below the surface for the full white-to-green spear and no drying stub at the crown - and out of season its true identity is the best dandelion weeder ever designed, which is most of the year's use.

Harvest nothing year one, two weeks year two, eight weeks from year three - patience compounds.

Asparagus's year ends with ferns feeding the crowns till frost, then a straw blanket over the cut-down bed - weed suppression for spring (the ONE serious chore an asparagus bed has) and freeze-thaw buffering for the crowns. Spears punch through the straw in April like it isn't there.

Cut ferns only after they brown fully - green ferns are still bank deposits.

The asparagus bed cannot rotate away from encroaching grass like the annuals do - it stands in one place for decades while the lawn probes the frontier every June. Tall steel edging sunk deep is the permanent treaty line, and it saves the hour of edge-weeding a month that otherwise never ends.

Six inches down minimum - quackgrass rhizomes are limbo champions.
