Diseases that affect these plants may remain in the soil and damage the berries. Plants may be set in hills or in rows. Red raspberry plants should be set 2' to 3' apart if planted in rows. Before planting, cut the tops of the plants back to six inches. Water after transplanting.
Blackberries do best in deep well drained soils such as sandy loams and loamy sands.
They should be planted in January or February but definitely by April 1. Space the plants 3.5' apart in rows. Space the rows 8' apart. Water after transplanting. They can be staked or tied to a trellis.
