| Prune your poinsettias in early spring after they are finished blooming, and the danger of frost has passed. Cut them back to within 12 to 18 inches (30.5 to 45.7 cm) of the ground. Pruning during growing season will produce a compact plant at flowering time. After four weeks or when the new growth is 12 inches (30.5 cm) long, cut the plant back, leaving four leaves on each shoot. Continue to pinch the plant back until the first of September. At that time stop pruning so it can develop colorful bracts in time for the holidays. |
