How to Grow Japanese Wineberries

Soil & Growing Conditions

Water: Prefers moist soil (NC State Extension; University of Maryland Extension)

Growth Stages

Stage	BBCH	Notes
Planting and establishment	0	Propagate by separating runners or by tip layering (RHS); NC State adds division, seed or stem cuttings as alternatives. Usually fan-trained. Where containment matters, note that canes cannot produce seed in their first year, so cutting canes back before they mature restricts spread (University of Maryland Extension).
Vegetative growth	3	Vigorous scrambling growth, spreading by underground stems and by canes rooting where they touch soil -- medium-to-rapid, a foot or more per year (RHS; University of Maryland Extension). Long canes covered in soft, bright red bristles.
Flowering	6	Small white flowers surrounded by bristly red calyces, in dense clusters in summer (RHS).
Fruiting, harvest and pruning	8	Small, sweet, juicy fruit ripens from golden yellow to red, glossy with a hollow core when picked -- a real identification feature distinguishing it from blackberry (RHS; University of Maryland Extension). Cut old canes to the ground after fruiting and tie in the new canes.

What the research guides add

Wineberry bears sweet fruit and is easy to grow, which is exactly why extension services in the eastern USA warn about it.

• It grows as arching canes that can reach nine feet. Canes are vegetative in their first year and in the second become woody and bear side branches, flowers and fruit; each cane lives two years, but the plant sends up new canes every year. (University of Maryland Extension)
• It tolerates a wide range of light, soil type and moisture, and is hardy to USDA zone 5 (annual minimum temperatures down to −20°F). (Vermont Invasives)
• NC State describes it as thicket-forming and able to become quite weedy; University of Maryland Extension calls it non-native and invasive and says it is found through most of the East Coast and Midwest. (NC State Extension, University of Maryland Extension)
• Vermont Invasives says it had escaped cultivation and become an invasive weed by the 1970s, has been recorded in most states east of the Mississippi River, and is listed as invasive in many eastern states, even though it is still used by gardeners and berry breeders for its fruit and its tolerance of varied sites. (Vermont Invasives)
• NC State describes the fruit as edible, sweet and juicy, eaten raw or cooked, and says songbirds and small mammals eat it; Vermont Invasives calls it sweet and somewhat tart. (NC State Extension, Vermont Invasives)
