Blackberries (Rubus family) are also called dewberries, boysenberries, marionberries and loganberries. Their dark, juicy fruit can be expensive or difficult to find in stores. Growing your own blackberries in Kansas is easy to do, and with proper care the plantings may be productive for 10 years or longer, according to Kansas State University.
Choose a site that is well-drained but retains moisture, such as a sandy loam. Do not use a site where potatoes, tomatoes, pepper, eggplant or strawberries have grown within the past three years, according to Kansas State University, because the fungus disease verticillium wilt may exist in the soil and infect your plants through the roots. A site located away from strong winds will help reduce cane breakage and increase fruit production, KSU says.
Add humus to sandy soils before planting, and place a handful of compost in the bottom of each planting hole.
Keep your plants in a bucket of water during the planting process to keep roots moist. Place your plants 4 inches deeper than they were in the nursery row; look for a dark gray line on the lower stem area, KSU says. Spread the roots out within the hole, and backfill the soil. Tamp down firmly to remove air pockets, then water deeply.
Cut your blackberries back to about 6 inches immediately after planting.
Mulch your young plants only in the late summer, after plants are established. Water weekly if there has not been adequate rainfall.
