How to Propagate Raspberry Bushes

Raspberries are perennial plants commonly classified as "bramble" for their thorny stems, or canes. The canes are biennial and produce fruit every other year, dying after the fruit is harvested the second season. The roots of the plants do not die, and produce new canes the following season. The fruit comes in various shades of red, black, yellow and purple. Propagate new raspberry bushes by dividing the suckers at the base of the parent plant.

Instructions

    • 1

      Prepare a planting site in an area of full sun with fertile and well-drained sandy loam. Raspberries prefer a soil pH of 5.8 to 6.5.

      Inspect plants for healthy suckers growing at the base of the parent plant. You can tell suckers apart from regular plant stems by a slight difference in leaf color and a lower number of leaves. Suckers also tend to grow vertically and sprout from the roots.

    • 3

      Dig down around the sucker to inspect for vigorously growing roots. If roots are healthy and strong, use a sharp spade to separate the smaller plant from the mother plant. Take care not to damage the larger plant in the process.

      Lift out the small plant with as many roots and as much surrounding soil intact as possible. Plant in the prepared site but do not plant very deeply. There should be only about 3 to 4 inches of soil covering the root area after planting. Space plants three to four feet apart.

      Water well and apply mulch to reduce weeds, maintain soil temperature and retain moisture in roots.
