Clematis that flower in early summer (May and early June) and have large, showy (and sometimes double) flowers are in Pruning Group 2. This means that they need some light pruning in late winter or early spring, then again after flowering in summer.
More on growing clematis:
In February or March (depending on the severity of the winter – check that you can see green buds beginning to swell), remove any dead or weak stems. Then cut back the remaining stems a little, to a healthy pair of buds. This will ensure that you enjoy flowers at eye level, rather than them all appearing at the top of the plant.
After the first flush of flowers in summer, prune back to a pair of buds halfway down the stems. This should encourage a second flush of flowers in late summer.
Pruning Group 2 clematis isn’t essential, but it will ensure evenly spread flowers, and a second flush.
Here are 10 beautiful Group 2 clematis to grow.
