Raspberries

Remove or cut back to the ground all fruit-producing canes after the berries are picked. Raspberries, like blackberries, are biennial. Prune red raspberry bushes in late March or early April by removing all weak and broken canes, and cutting back tall canes to about 5 feet. Prune black and purple raspberry bushes twice besides after fruiting. In the spring, cut back lateral branches to 8 or 10 inches. In the summer, cut the top 2 to 3 inches of new canes once they reach 2 feet for black raspberries, and 30 inches for purple ones.

Currants

Red, white and black currants are grown in Alberta, Red and white currants bear fruit on spurs of two and three-year-old canes. Older canes bear inferior fruit, so pruning is aimed at keeping old wood thinned out and new wood growing in. The well pruned red or white currant bush will have three stems each of three, two and one year old wood. Black currants, on the other hand, bear their fruit on last season's growth. It is, therefore necessary to keep new growth coming in the old growth almost totally cut back, Ideally black currants should have 9 canes with three to four two year old canes and five to six canes from the previous year's growth.
