Set raspberry plants in early spring. Prune the canes to within six inches of the ground at planting time for best results. For home garden plantings, a single hedge row at one end or along one side of the garden is desirable. Space new plants 3-4 feet apart in the row. They will fill into a solid hedge row when cultivated on both sides of the row. Raspberry plantings should be cultivated thoroughly and frequently. If weeds and grasses get a start, they are difficult to control.
Raspberries are extremely hardy, so no special protection is needed except in the coldest mountain and plains climates. Where winter temperatures stay extremely low for long periods, and winds add to the chill, you should protect your plants in the following manner: Lay canes of the current season along the row or trellis, pinning portions that arch upward. Be careful not to snap them. Where mice are not likely to be a problem, cover the canes with straw or sawdust to a depth of several inches, and then cover the mulch with poultry netting to hold it in place. If winter mouse damage is probable, bury the canes under 2″ of earth.In spring, uncover the canes before they begin to leaf out, just as the buds swell. If the buds break white still covered, they will be extremely tender to even light frost.
