Trellis Systems
The home garden environment provides some unique opportunities for trellising. Consider growing thornless blackberries along a split-rail fence, or use thornless blackberries or black raspberries as a screen on a 6-foot fence. You are limited only by your imagination!
Trellis systems generally do not affect the type of pruning a plant receives. In other words, black and purple raspberries still require summer tipping, but the trellis determines the height of tipping. Trellises allow plants to support more surface area for fruit production. Several trellises have been experimented with successfully. See Figure 7.3 for possible trellis designs.
