How to prune dipladenia (mandevilla)

Late winter to early spring before active growth; pinch tips throughout summer. Cut main stems back by one-third to one-half using clean, sharp pruners, cutting just above a leaf node. Pinch soft stem tips during the season to promote branching and more flower buds.
