How to prune ipomoea nil 'scarlett o'hara'

Pinch growing tip once in late spring at 15–20 cm height. Pinch the main stem tip above a leaf node when the seedling reaches 15–20 cm to encourage lateral shoots and a fuller habit. Train stems onto support; no further pruning required during the season.

Once at establishment; otherwise not needed. Ipomoea nil 'Scarlett O'Hara' is a vigorous annual morning glory that needs only a single tip pinch at establishment to branch well. Beyond that, pruning is unnecessary and may delay flowering. Deadheading spent blooms is optional — the plant flowers freely regardless. Clear the entire plant at first frost.
