We have just moved into a house with a proper garden for the first time. It's an enormous, but overgrown mature garden. I had read that the buddleia should be cut back in early March so I expected to be able to be moved in in good time, but everything is growing already. There's new growth on all the plants, some of the trees are already in blossom. Will I kill them if I cut them back in a week or two?
Thanks from a bit of a newbie!
