Do You Deadhead Summer Flowering Clematis?

Clematis bloom whether you prune them or not. Deadheading – removing dead flowers – makes some plants more floriferous, but only those that are fertile. A number of clematis hybrids are sterile, which means that deadheading has no effect on their production of blooms.

How do I keep clematis blooming all summer?

Usually, the problem isn't lack of fertilizer, but too much, which may produce lush foliage and few blooms. As a general rule, clematis benefits from a handful of 5-10-10 fertilizer in the spring, along with a layer of compost. Apply a water-soluble fertilizer once or twice during spring and summer.

Should I deadhead summer flowering clematis?

Deadhead spent flowers for another series of blooms, though they will likely be smaller than the first, as these appear on new growth. When deadheading the first blooms, as much as 12 to 18 inches (31-46 cm.) of stem can be removed. This rejuvenates the plant and is often the best means of pruning clematis vines.
