When should I prune ipomoea purpurea?
Pinch seedling tips in late spring after transplanting. Pinch or snip the main growing tip just above a leaf node when the plant is 15–20 cm tall to promote lateral branching and a fuller, more floriferous plant.
How often does ipomoea purpurea need pruning?
Once at establishment; otherwise as needed to manage spread. Ipomoea purpurea (common morning glory) is a fast-growing annual that rarely needs pruning. Pinching out the growing tips when seedlings reach 15–20 cm encourages branching and more flowers. Beyond that, simply let it climb. As an annual it dies at first frost, so no long-term pruning program is needed.
