I have several clematises, and am wondering what to do with them re pruning.
Read that the montanas shouldnt be pruned but have also read that you are supposed to cut them all down to 30cm in the first year to encourage growth, regardless of what group they are in.
My query is that I have just bought some (2 are montanas and 2 the larger hybrid type) and dont know whether they need cutting back in the spring or not. They are about 18" high and look dead at the mo, but have been assured that they are not! Does this count as the first year or are they older than that?
