Select raspberry vegetative, or leafy, tips that are still green yet firm during the spring or before dormancy in the fall. These tips should not be woody.
Cut the tips off of the mother plant with sharp, disinfected pruners about 6 inches from the tip of the cane. Remove any leaves from the 2 inches of the cutting nearest the cut.
Dip the stem in rooting hormone. Use a pencil to make a 2-inch-deep hole in a small planting container filled with damp potting soil. Gently set the cutting into the hole, being careful not to scrape off the rooting hormone in the process.
Firm the soil lightly around the cutting. Set it in a location with dappled or partial sun, preferably indoors near a window. Mist the leaves daily with a water spray bottle and keep the soil moist but not soggy until roots form. This should take up to two weeks. Transplant the rooted cutting to a garden location in spring.
Remove a sucker from the mother plant with a sharp knife where the sucker meets the mother plant. Suckers generally originate from the roots near the trunk of the mother plant.
Plant the sucker in rich, well-drained soil in a sunny location. Stake it with a bamboo pole at least 3 feet tall. Bury the pole 8 inches to a foot in the ground, then tie the sucker to the pole with arbor tape.
Water the sucker thoroughly, and make sure the ground is lightly moist while the sucker establishes. Protect the developing root system from temperature and moisture extremes with 3 inches of mulch.
