Transplanting Asparagus

Asked September 25, 2014, 4:17 PM EDT

- I Just saw the answer in another post I did not see before posting. I have a three year old asparagus plant, that has been growing well over the three years and we have been patient on picking the asparagus in the spring per the recommendations on the site for asparagus. Here is the question...We would like to move the location of the asparagus in the garden, what is the best time and method for asparagus transplant. Thank you for your time.

Early spring is the ideal time to transplant asparagus although the fall is acceptable as well. When an asparagus bed is well established, it is often recommended to start with new crowns rather than trying to dig up the established roots of the old ones. However, since your plant is only three years old, it should be easy enough to dig up. I have also included some addition info on general asparagus care. Soils – Asparagus tolerates a wide range of soils as long as they are well drained. It prefers soil high in organic matter, and full sun (eight hours/day minimum). Fertilizing – Asparagus is a heavy feeder. Fertilize in spring as growth starts and again in mid-summer after the harvest period. Mulching – Asparagus competes poorly with weeds and other crops for water, nutrients, and space. Organic mulch is recommended. Mulch also provides winter cold protection for the roots. Harvesting – The asparagus bed can be weakened or destroyed by over harvesting. The harvest period for an established bed is only four to six weeks (May into mid-June). Harvest only larger spears. Stop harvesting if spears decrease to pencil size or smaller. Leave the ferns (foliage) to grow until fall or let stand through the winter, finally cutting before new growth begins in spring. Planting – Extra efforts in plantings new beds pay off with increased production. 1.Thoroughly work in four inches of well-composted and aged organic matter through the soil to a 12 inch depth. 2.Before planting, soak roots in warm water for a couple of hours. 3.Dig a trench four to five inches deep and wide enough to accommodate the spread-out roots. Space roots, typically 18 inches apart, covering with only two inches of soil. 4.Add additional soil during the growing season, as plants grow. Asparagus roots are easily smothered if initially covered too deep. (Many texts talk of planting six to eight inches deep for better protection form cold winter soil temperatures. However, this deep planting will decrease yields.) When planting from seed, start seeds indoors 12 weeks prior to transplanting outdoors. Harden off seedlings before transplanting outdoors.
