The species is a perennial plant which bears biennial stems ("canes") from the perennial root system. In its first year, a new stem ("primocane") grows vigorously to its full height of 1–3 m, unbranched, and bearing large pinnate leaves with three or five leaflets; normally it does not produce any flowers the first year.
Depending on the species, many temperate plants can be pruned either during dormancy in winter, or, for species where winter frost can harm a recently pruned plant, after flowering is completed. In the temperate areas of the northern hemisphere autumn pruning should be avoided, as the spores of disease and decay fungi are abundant at this time ...
Blackberries are perennial plants bearing biennial stems (called canes) from their roots. [8] In its first year, a new stem, the primocane, reaches a full length of about 3–6 metres (9.8–19.7 feet) trailing on the ground and bearing large palmate compound leaves with 5–7 new leaves; it does not produce any flowers.

Often extreme winter weather sets in before fall pruned roses are fully winter hardy. The rose will likely suffer stem dieback to near ground level or the whole plant might not survive. Bottom ...
Tip-bearers should be pruned lightly in winter using the regulatory system (see above). Any maiden shoots less than 25 cm (10 in) in length should be left untouched as they have fruit buds at their tips. Longer shoots are spur pruned to prevent overcrowding and to stimulate the production of more short-tip-bearing shoots the following year.
The blackberries, as well as various other Rubus species with mounding or rambling growth habits, are often called brambles. However, this name is not used for those like the raspberry that grow as upright canes, or for trailing or prostrate species, such as most dewberries, or various low-growing boreal, arctic, or alpine species.
