Stem Cuttings

• Cut a 6-inch piece of stem from a newly growing cane. Select stems that are green, healthy and still tender, rather than woody. Remove the leaves from the bottom half of the stem and dip the tip in rooting hormone. Plant the bottom portion of the stem in a pot in a mixture of perlite and peat or peat and sand. Mist the plant frequently to keep it moist, but not soggy. Plant it in a larger pot containing potting mix in three to four weeks, when the stem has grown small, white roots. Transplant the cutting outdoors when it stands 12 inches high.
  
  

Root Cuttings

• Dig the soil under the blackberry stand to reveal the roots. Cut off several 6-inch lengths that are at least 1/8 inch in diameter. Bury the roots in soil, covering them with 1 to 2 inches of soil. Keep the area watered so it is evenly moist. Plants from the root cuttings will emerge somewhat unevenly the first year. By the second year, the plants spread and fill out.
  
  

Suckering

• Raspberries and blackberries produce suckers that may emerge several feet from the mother plant. Sever 1-year-old suckers in spring before the weather turns hot by cutting them with a sharp spade or scissors. Plant them in their new location and keep them well watered. Newly emerging suckers are less reliable transplants because they lack a strong root system. They often dry out and die when transplanted.
  
  

Tip Layering

• Follow Mother Nature's lead by tip layering to produce a few new plants. Bend a healthy stem to the ground and cover a small area of the branch in 3 to 4 inches of soil, leaving 4 inches of the stem's tip exposed. Eventually the area covered in soil produces roots. Allow the new plant to continue to grow in its current location, or snip it from the mother plant and move it.
