Set the trellis posts 15' to 30' apart and run wires between them. Most red raspberry varieties are stout caned and can be planted in hills without training them to stakes. For ollalies build a 4.5' trellis and run the first wire 1.5' from the ground, the second wire one foot above the first, and so on. Only the crown and the roots are perennial. Old canes should be removed as soon as the fruit is harvested.
New canes grow from buds on the base of the old canes.
Two new shoots usually come up each year. In addition, suckers grow directly from the roots of red raspberries. The new canes and suckers should be thinned immediately after harvest. Blackberries should be pruned as soon as the harvest is completed. All wood that has produced the current crop should be removed.
