Raspberry - Planting and Care Guide
Raspberries grow best in cool climates, and tolerate a wide range of soil types from sandy loam to clay. The most important requirement for the berries is that the soil be deep so that the roots are not restricted. Raspberries should not be planted in an area following the cultivation of tomatoes, eggplant or potatoes. Diseases that affect these plants may remain in the soil and damage the berries. Plants can be grown in hills or in rows.
Red raspberry plants should be set 2 to 3 feet apart if planted in rows. Before planting, cut the tops of the plants back to six inches. Set the plants into the hole so they are 2 to 3 inches deeper than they were in the nursery. Water after transplanting.
Raspberries should not be planted in areas where eggplants, peppers, potatoes, or tomatoes have been grown within the last three years because they are susceptible to verticicillium wilt with is associated with these plants. Raspberries should also not be planted in areas where previous raspberries have been planted for 7-8 years due to possible root rot disease. Plant new canes in fresh patches, well draining soil.
Summer Fruiting Raspberry Plants - floricane-fruiting
The majority of raspberry plants are summer fruiting and bear fruit on the previous year's growth - so you will find that you will not have fruit the first year after planting. Once the cane has fruited, in its second year, each cane should be cut to ground level. Remove the old canes, and then examine the new canes, looking for the biggest and strongest canes, about four to eight per plant. Prune out the others which will encourage the plant to put all its energy into producing fruit rather than vegetative growth
Autumn Fruiting Raspberry Plants - primocane-fruiting
Autumn fruiting raspberry plants produet fruit in the first year of planting - starting in August until October in a warm year. These cultivars are very popular as they begin to fruit as the other canes finish. Prune all canes to ground level each February to make way for the new season's growth.
To get maximum yields from raspberries, apply fertilizer every year in the early spring just as new growth begins. Manure works well as does a commercial 5-10-5 fertilizer. Apply this as a top dressing at the rate of 8 ounces per plant, or spread in a wide band no closer than about 6 inches from the crown around each hill.
