How to Grow and Care
Chocolate Vine is a light feeder and doesn't require supplemental flower fertilizer. However, you can provide trace nutrients for vines growing in poor soil by mulching with compost or well-rotted manure.
The Chocolate Vine will climb on supports or scramble up to 40 feet (12 m). Because of its vigorous growth habit, many gardeners prune the chocolate vine back to ground level in late winter to keep it in check. You can also lightly prune the vine to help it look tidy after flowering.
Practice good stewardship of the land by not allowing Chocolate Vine to escape your landscape into neighboring woodland areas. In some areas, it has displaced native plants with dense vegetation. In addition, the vines can choke out small trees when left untended in wild areas.
