Garden FAQ: Wild and Backyard Raspberries

Question:
We are planning to plant backyard red & black raspberries and some wild black raspberries which grow around our rural home. Will the plants mix up from cross pollination and will wild berries planted in same areas diminish the domestic varieties fruit size or flavor.

Answer:
Wild raspberries and should be kept 300 to 600 feet away from your new backyard red and black raspberries. Not because they might cross pollinate, but because wild berries can be a source of Verticillium or other virus diseases. It would be better to not plant the raspberry plants in the same area where tomatoes, potatoes and eggplant have been grown for the same reason. Raspberries are self-fertile, but studies have shown that cross-pollination with other backyard raspberries does increase fruit yield.
