Early Autumn - Before planting clear ground of weeds; dig a trench one spit deep by three spits wide and add a layer of well rotted manure to the base. Fill in with the top soil and add balanced fertilizer.
Construct support – three strands galvanised wire 50cm apart between stout posts about 2m tall. Posts 3-5m apart.
Plant bare rooted certified canes when dormant (November to March). Shallow rooted so only plant 7-8cm deep. 40cm apart in rows 1.5m apart. Cut canes to 30cm immediately after planting to encourage new canes to develop.
Pruning – summer fruiting types fruit on previous years canes; autumn fruiting on this years. After fruiting cut out fruited canes. Retain the strongest 5-8 un-fruited canes per plant for summer fruiting types and tie in to the wires. Cut the tops 15cm above the top wire.
Watering – shallow rooted so need regular watering in dry weather.
Feeding – sulphate of potash in January; superphosphate every third year; sulphate of ammonia in late March, then mulch.
Raspberry beetle – the grubs tunnel the fruit and make it inedible. Control – use a pheromone trap to detect the problem and a pyrethrum based spray from beetle emergence until first flowering.
Birds – net or cage the crop.
Grey mould ( Botrytis cinerea ) – grey fluffy mould on leaves and fruit. No approved chemical control – improve air circulation and remove and destroy infected canes (or individual leaves etc if mild problem)
Cane blight - Serious fungal disease that enters through damage to canes. Canes wilt and die. Remove and burn affected canes; control by copper fungicide spray.
In early Autumn clear ground of weeds. Single dig and incorporate well rotted manure. Add a dressing of balanced fertilizer.
November to March, plant bare root bushes in a hole large enough to take the roots spread out to the same depth as it was planted in the nursery. 1.5m apart (Cordons planted 50cm apart against a framework of wires and posts or against a wall and tied in) and 1.5m between rows.
Feeding- balanced fertilizer and sulphate of potash in February. Mulch with well rotted manure but do not let it touch the stem.
