Remove all weak, diseased, and damaged canes at ground level in March or early April. Leave the most vigorous canes, those approximately 1/4 inch in diameter when measured 30 inches from the ground. After thinning, the remaining canes should be spaced about 6 inches apart.Īlso, prune out the tips of the canes which have died due to winter injury. Cut back to live tissue. If the canes have suffered little winter dieback, remove the top 1/4 of the canes. Cane-tip removal or "heading-back" prevents the canes from becoming top-heavy and bending over under the weight of the crop. The growth and fruiting characteristics of fall-bearing red raspberries are slightly different. Fall-bearing varieties naturally produce two crops. The first crop is produced in late summer or early fall at the tips of the current season's growth. The following year, a summer crop is produced on the lower portions of these same canes. After the second crop, the canes die.Ī number of yellow raspberry varieties are also available. With the exception of fruit color, the growth and fruiting characteristics of yellow raspberries are identical to red raspberries. The shoots of purple, black, and summer-bearing red raspberries are strictly vegetative during their first growing season. The following year, these same canes flower, produce fruit, and then die.

The growth and fruiting characteristics of the raspberry plant are rather unique. The plant's roots and crown are perennial, while the stems or canes are biennial. Each spring, purple, black, and red raspberries produce new canes from buds located at the base of the previous year's growth. Red raspberries also produce new shoots from buds located on their roots. The individual canes live for 2 years and then die.

Proper pruning of raspberries is essential. Pruning produces higher yields, helps control diseases, and facilitates harvesting and other maintenance chores. Pruning procedures are based on the growth and fruiting characteristics of the plants.
