We added 40 asparagus plants to the garden this year. Asparagus is a perennial so we won’t be moving it from bed to bed, nor will it have anything else planted in its beds. We used one 8×8 bed and one 4×8 bed. Each bed should be productive for about 15 years! Each crown/plant can produce a half pound of spears when mature.
Asparagus needs light, loamy, fertile, deep and well drained soil. We used compost, peat moss, manure, and sand. Then we top-dressed the beds with lime.
We can’t cut any asparagus this year and only a wee bit next year. Each year after than we can cut spears every three days until the third week in June. Then we let it grow until fall. In the late fall we are supposed to cut the ferns and muck the bed well.
Harvesting
Harvest asparagus by snapping 7 to 9 inch spears with tight tips. There is no need to cut asparagus below the soil with a knife. This may injure other buds on the crown that will send up new spears. The small stub that is left in the soil after snapping, dries up and disintegrates. A new spear does not come up at the same spot, but comes up from another bud that enlarges on another part of the crown.
As the tips of the spears start to loosen (known as “ferning out”), fiber begins to develop at the base of the spears, causing them to become tough. The diameter of the spear has no bearing on its toughness. When harvesting, the asparagus patch should be picked clean, never allowing any spears to fern out, as this gives asparagus beetles an excellent site to lay their eggs.
The year after planting, asparagus can be harvested several times throughout a three-week period, depending on air temperatures. Research shows there is no need to wait two years after planting before harvesting. In fact, harvesting the year after planting will stimulate more bud production on the crown and provide greater yields in future years, as compared with waiting two years before harvesting.
When harvest is finished, snap all the spears off at ground level. New spears will then emerge, fern out, and provide a large canopy to cover the space between the rows. Once a dense fern canopy is formed, weed growth will be shaded out.
