Hack away late bloomers
It’s hard to believe the new growing season is already started and that growth will begin in earnest in a few short weeks. It can seem a bit confusing when you read about pruning existing Clematis as they can be broken down into three groups depending on when they flower. Suffice to say if you have Clematis that will be coming into flower over the next two months leave them alone as their flower buds will form on growth that is already there; that is, if the buds aren’t visible already.
If, however, you have Clematis which flower later in the summer, these tend to be the larger flowering varieties, then take action now. Simply hack them back — and that’s being technical. They will thrive this year if you cut them back to within 25cm off the ground.
