Boysenberries were developed from European raspberries and three different varieties of native blackberry. Boysenberry vines prefer deep, well–drained, fertile soil. Boysenberries bear fruit on 2–year old wood. Boysenberries have an erect or semi-erect growth habit and can be grown with only minimal support such as a post, trailing types need more support. Boysenberries tend to spread by tip layering so unless you want more blackberry vines cut back long vines before the tips reach the ground and root. These brambles thrive in most soil types but they do not tolerate poor drainage. Boysenberries are versatile and hardy but are not as cold hardy as other brambles. Boysenberries are successful in USDA Zones 7-11. Plant late winter to early spring. Space 2’–3’ in a row with 8’–10’ between rows. Sold by the individual plant.
