Asparagus Tips & Tricks2017-04-10T08:08:12+00:00

Plant asparagus roots or crowns in late winter/early spring (February in Texas). Prepare beds with heavy amounts of compost and organic fertilizer. We recommend using a mycorrhizal root inoculant at the time of planting as this has been shown to greatly increase yields in asparagus. Be sure to plant in full sun (at least 6 hours) and make sure that the soil drains well.

Make sure that you plant asparagus in a permanent area, so plan carefully. Dig a trench 8 inches deep and wide enough to accommodate the outspread roots (about 10 inches), then space the asparagus 18 inches apart. Leave four feet between rows. Cover the roots with two inches of soil, and continue to fill in the trench as shoots grow. Be sure to not bury the green shoots completely. The trench can usually be filled by the end of the first growing season, but if not, simply continue to work on it the second year.

Break off spears when 6” to 8” tall as they emerge in early summer. Do not harvest any shoots for the first two years.  Harvest only small amounts at first and then increase picking time up to six weeks. After that let shoots mature to fern like growth to allow regeneration of energy for next year’s crop. Work compost and organic fertilizer into the soil every spring.  Do not overwater asparagus as this may cause crown rot and loss of new or established plantings.
