Training and Pest Control Unlike Latham and other standard raspberries, Heritage and other everbearing raspberries do not have to be trained to a trellis. The primocanes are erect, sturdy and rarely require support. Heritage suckers prolifically and will form a mature hedge in about 3 years. Hedges should be contained by cultivation, discing, or rototilling. Hedges are generally maintained at 2-3 feet wide.
Wider hedges yield smaller berries and are harder to pick.
Cultivation will control most weeds within the alleys. Because raspberries have relatively shallow roots, cultivate no deeper than 2 inches. Annual weeds within the hedgerow can be controlled with preemergent herbicides. Information on registered herbicides for use on raspberries can be obtained from your county Extension agent. Perennial weeds should be eliminated before the planting is established.
