Pruning Clematis Montana
I am replacing a leaky old shed with a potting shed in the Autumn.
When we arrived at my present house 7 years ago, I disguised the old shed with two Clematis Montana and sure enough they have covered it, beautifully.
The usual pruning time I believe is after flowering, which I don't do as the birds like to nest in the clematis during spring and summer. I usually just tidy up the end growth late in the year.
So my problem is that the stems are quite thick near the base and I want to retain the clematis and train some leaders around the sides(away from the window) and over the top of the new shed if possible.
Would this kill the plants? or should I replant with new specimens? Yes I know that clematis are not planted in the same area as before or is this untrue?
Thanks in anticipation.
This is what the RHS has to say on pruning established clematis in Group 1, which includes Montana.
You will find you don't have the flowers next year, but it may solve your problem. Montana is usually quite tough. I would have thought it would survive a prune now even though it's late. There is time for it to make some new growth by autumn. You could leave the stems you want as a framework and shorten them.
I have a clematis I think its henry.I dont know what group it is.I have had it for years .I dont prune it because it always grew on old wood, this year it grew on the top and nothing on the bottom.Should I cut it way down and see what happens ,I dont want to kill it its so pretty.It has big white flowers and is growing on large arborvites
When does it flower Debra?
Clematis Henri is group 2, Light prune. You can prune it halfway after the first flowering and lightly trim back to healthy buds in the spring.
