Pruning clematis is easy too – that’s true! Once you know our easy-to-remember circumcision tip, that means…read on. If low-maintenance flower-covered vines sound like something your garden needs, then let’s dive into the complete guide to growing clematis! Clematis is a genus of perennial flowering vines in the Ranunculaceae or buttercup family. Numbers vary, but there are an estimated 300 to 400 known species native to Asia, Europe, Oceania, and North America with thousands of cultivars available. Most are climbers with fast-growing, woody vines that scale, spread, and trip over anything that gets in their way. But there are also some upright (i.e. non-climbing), herbaceous shrub species such as C. recta and some that make excellent ground covers such as C. praecox.

How do I grow
Clematis can be planted in spring, summer or fall. If planted in spring or summer, it is best to occasionally pinch out the growth tips during the first growing season. They like a cool, deep, and moist root run, and a little extra time and care invested in creating the ideal planting location will ensure the best possible performance. The vines prefer loose, loamy soil with good drainage and a slightly acidic to neutral pH of 6.0 to 7.5 in full sun. Before planting, soak the root ball (in its nursery pot) in a bucket of water for about 15 minutes. Create a large planting hole that is 18 to 24 inches wide and deep.
