Don’t pack away your secateurs for the winter just yet!
If you have any Caryopteris, Perovskia (aka Russian Sage), or woody-stemmed Salvias – such as Hot Lips, Royal Bumble, Midnight or Blue Monrovia – now is a good time to cut them back by half.
These hard prunes encourage bushy regrowth and prevent them from looking straggly and scruffy as they mature.
You will find much disagreement over whether autumn or spring is the best time to prune lavender, but whenever you do it, make sure you cut off the top few inches of leaf as well as the old flowering stems. This stimulates fresh growth lower down the plant, which should reduce problems of a woody, straggly appearance.
