Growing Berries in Your Backyard
See more detail in the pdf of Figure 16.1, linked below.
Plant raspberries from late fall through early spring. Dig a shallow hole wide enough to accommodate the roots. Prune off any damaged root parts. Spread the root mass and set the plant so that the primary roots are no more than 1 to 2 inches below ground level. If the primary roots are planted much more than 2 inches below the soil surface, the roots may not have enough energy to push shoots up through the ground. Cover the roots with soil and press firmly to remove air pock¬ets. Water the plants to settle the soil. Cut the canes on newly set plants to 6 inches long. In a hedgerow system, red raspberry plants are spaced 2 to 3 feet apart in the row, with 8 to 10 feet between rows. Allow the new canes to grow and spread along the row, but prevent them from spreading wider than 12 to 15 inches (or the top of a raised bed) by removing the suckers that grow outside the row. Space black and purple raspberries 3 to 4 feet apart in the row, with 8 to 10 feet between rows. Remove any suckers that grow outside to row.
