Planting and cultivation
There are two kinds of raspberry: summer fruiting, and autumn fruiting. Both should be planted between late autumn and early spring in soil enriched with compost. Plant so that the root system is about 7.5 cm (3 in) deep and the individual canes are about 45 cm (18 in) apart. Subsequent rows of raspberries should be at least 1.2 m (4 ft) apart. Feed annually in early spring with general fertilizer at the rate of 135gm per sq m (4oz per sq yd). In mid-spring surround the canes with a moisture-retaining and weed-suppressing layer of compost or peat. Weeds should be kept down with either a hoe (used carefully to avoid damaging the roots) or, better still, a chemical weedkiller.
Summer raspberries need support to prevent their falling over in windy weather. This is best provided by tying the canes to wires, strained horizontally between stout wooden posts at 1 m (3.5 ft) and 1.5 m (5 ft) from the ground. Autumn fruiting raspberries rarely exceed 1.5 m (5 ft) and can be grown without supports.
Pick the fruits when they are well coloured and are easily removed from the stalks.
Pruning and training
All newly planted canes should be cut back to 15 to 30 cm (6 to 12 in) after planting. In the first summer after planting neither the summer nor autumn fruiting raspberries require any pruning. All the canes of autumn fruiting raspberries should be cut to the ground annually in late winter. Summer fruiting raspberries are pruned immediately the fruit has been harvested by cutting away all those canes which have borne fruit. The new season’s canes are tied in to take their place. With both autumn and summer raspberries you should limit the number of canes from any one plant to six.
Pests and diseases
Aphids, and raspberry beetle (spray with insecticide when the fruit first shows colour).
