Yesterday I cut back hard a Clematis Montana (Freda) by mistake. I know they are not normally meant to be pruned. It's only a couple of years old - will it…
They are fully to half hardy. They will require a rich soil that is kept moist, but it is well drained. They should be grown in full sun, but the roots will require shade and protection from too much heat.
You can propagate the cultivars in the early summer by softwood or semi-ripe cuttings or layering.
