How to prune moonflower

Tip pinch in early growth (spring); annual removal at season end (or late-winter cut-back in frost-free gardens). Pinch the main tip at 15–20 cm after planting to promote branching. Guide stems up a trellis or fence. In frost-free gardens where the plant persists, shorten all stems by half in late winter to refresh growth.

Pinch growing tips at 15–20 cm to encourage branching and more of the fragrant white blooms. No deadheading or structural pruning is necessary. Remove the plant at season's end. In frost-free climates where it overwinters, cut back by half in late winter.
