How to grow Blackberry, bramble
Planting
Plant in autumn or late winter against wires strained between posts, or along a fence. Allow at least 2.5 m per plant for vigorous kinds; compact thornless cultivars need less. Cut the plant down to about 25 cm after planting to force strong new canes.
Pruning
Fruits on canes produced the previous year. After picking, cut every fruited cane out at ground level and tie in the new canes that grew this season. Keeping old and new canes on separate sides of the support, or fanning new growth up the middle, makes this much easier to do cleanly.
Propagation
Tip layering works almost too well: bend a cane tip to the ground in late summer, peg it down and cover with soil, then sever the rooted plant the following spring.
Pests and diseases
Raspberry beetle grubs affect blackberries too, showing as dried patches at the stalk end of the fruit. Purple blotch and cane spot mark the canes in wet seasons. Birds take ripe fruit.
Value to wildlife
Among the most valuable garden plants for wildlife — nectar for bees and hoverflies, berries for birds and mammals, and dense thorny cover for nesting and shelter.
Notes
The species name covers a very large aggregate of closely related wild brambles that vary in vigour and fruit quality. Garden cultivars are far better behaved than wild seedlings, and thornless kinds are worth the modest loss of flavour if space is tight.
