Answer: I think February is a good time to prune your Mandevillas. Most gardeners prune in late winter or early spring before growth begins. Prune by removing old, crowded stems and shortening others. Even if mandevilla is pruned almost to the ground, it will bloom the same summer on the new shoots, which develop from the base of the plants. Wait until spring, then fertilize with a 20-20-20, according to package directions (usually every 3-5 weeks during the spring and summer months).
Enjoy your beautiful plants!
