I have a lovely shrub white flowered hebe, and have had a few success with cuttings. Am I too late to prune them. They finished flowering approx a month ago, and already show signs of new leaf growth. Picture 1 is the established Hebe - nicely bushy but with a few yellow leaves and plenty of new shoots.Picture 2 is one of the cuttings - 18 months old, but quite straggly. I don't want to cut off the next flowering stems, but feel that this plant should be more compact. Recommendations please.
