Raspberry plants have perennial crowns and biennial canes. Most varieties grow from the second-year canes, but some late-harvest types grow from first-year canes at the end of the growing season. Plant raspberries in rows and construct a trellis for support, or plant them next to a fence or lattice trellis. Raspberries need full sun and loamy, well-draining soil. Plant the crowns in the spring after the last severe frost has passed. Raspberry plants produce for 10 to 20 years with proper care and attention.
Turn over the soil in the planting area with a garden fork or shovel. Mix in 1 part seasoned manure to 2 parts soil. Prepare the planting bed three to four weeks before planting.
Dig a hole 3 inches deep and 12 inches wide. Place the raspberry crown into the shallow hole and spread out the roots. Cover the crown with soil and pat down the area firmly with the flat of your hand. Space multiple plants 16 to 18 inches apart.
Cut the canes down to 1 foot tall immediately after planting. Make a clean cut just above a bud, suggests BBC Gardening. Water each plant until the soil is damp to a depth of 3 inches.
Water every three to four days for a total of 1 to 2 inches of water per week through the growing season. Water less to compensate for rain or damp weather.
Fertilize in the early spring at the beginning of the growing season with a balanced 10-10-10 fertilizer. Check the package for appropriate application. Mulch the area around the canes with seasoned manure to provide additional nutrients and keep the weeds down. Spread mulch 2 to 3 inches think and keep it at least 1 inch from the base of the canes.
Prune off second-year canes at the end of the harvest season. Use a sharp pair of shears and cut them at the ground. Second-year canes are distinguished from first-year canes by their woody bark; first-year canes are green and springy.
