Do not cultivate in the fall. This tends to stimulate new growth, which is susceptible to winter injury. In late November, cover plants with straw or leaves to a depth of 6 inches. In spring and summer, maintain a 4 inch mulch layer to reduce soil moisture loss and aid in controlling weeds. Mulching partially reduces the need for cultivation and can also help increase yields.
Irrigation is necessary.
Manure from a stable, if available, is a good fertilizer for raspberries. Apply the manure dry and at the rate of 1 pound per square foot. For the commercial fertilizer, apply 2 to 3 pounds of actual nitrogen per 100 feet of row. Apply fertilizer in the late fall after growth has stopped or in early spring before growth begins. Harvesting Raspberries, depending on the variety, can be harvested from late June through September.
