How to Prune Florist Kalanchoe
When is the best time to prune?
Florist kalanchoe blooms in response to short days, so pruning after the bloom cycle in spring gives the plant a full growing season to set new buds.
Why Should I Prune My Florist Kalanchoe?
Florist kalanchoe is one of those plants people often toss after the flowers fade, but with a little pruning it will bloom again. The key is removing the spent flower stalks so the plant redirects energy into new growth instead of trying to set seed.
Once the flowers are done, cut each flower stalk back to where it meets the main stem. Then look at the overall shape. If stems have gotten tall and leggy, especially from low light during winter, trim them back to a leaf pair about halfway down. This encourages branching and gives you a fuller plant next time around.
Kalanchoe is a succulent, so it handles pruning well as long as you let the cuts dry out. Don't water for a day or two after trimming. Use clean, sharp scissors or pruners since the stems are soft and crush easily with dull blades.
To get your kalanchoe to rebloom, it needs about 6 weeks of long nights (14 hours of darkness) in fall. Pruning in spring gives it the whole summer to grow new stems that will carry next winter's flowers.
