Hello! I planted a clematis last Spring (General Sikorski) and was wondering if you prune newly planted Clematis – or wait a few years? What information I have is that it is Group 2 and should be pruned immediately after blooming(?) – but I wasn’t sure if this was for well-established Clematis or if I should let it grow for a couple of seasons? Thanks in advance for any help – love the new site features!
The biggest mistake with newly planted Clematis of any kind is just letting them develop a spindly shoot or two rather than first encouraging a strong root system. In late winter/early spring the first couple of years, prune the plant back hard. I can’t tell not seeing it if that means to 8 or to 12 or to 18 inches on your particular plant, not knowing how big it was when you started and is now.
You want to cut just above some strong leaf buds, and then offer the plan support regularly as it grows this year. Repeat next spring (at least).
Terrific – thank you for the response. This was about 2ft. high with some blooms when I planted it last year. I will look closely when I prune and give ample support. Thanks again!
