Trace the long wippy growth from last summer back towards the main framework of the plant. Make an angled cut, pruning back to a couple of fat buds leaving a spur of about three or four inches.
A couple of hours later and the winter prune is done. Depending on your soil you may want to beef up last autumn’s mulch with some light, garden compost to promote spring growth. Now leave the rest to nature and hopefully it will develop like this.
