Which pruning group is my clematis?

Tool — Answer three quick questions about when and how your clematis flowers to find its pruning group, what to do and when.

When does your clematis flower?

Following RHS and British Clematis Society advice: flowering before June on the previous year's growth means group 1 (no routine pruning, trim straight after flowering if needed); large flowers in late May to June on short shoots from last year's stems, often repeating in late summer, means group 2 (light trim to the first strong buds in February or early March, and again after the first flush); flowering from late June on the current year's growth means group 3 (cut hard to the lowest healthy buds, 15–30cm up, in February or March) – a rule of thumb, since some cultivars such as 'Jackmanii' or 'Perle d'Azur' can be treated as group 2 or 3. — Sources : Clematis: pruning (RHS)
