For various reasons, mostly painting and decorating in the house, I am behind with what should have been autumn pruning. Of particular concern are Phlomis, Cistus, Helichrysum and Santolina. They are all looking pretty miserable as we have had a run of sub zero temps. Even the Euphorbias look as though they would like to expire. I am seeking advice as to whether I prune now when there may be more cold ahead, or should I wait until the plants come alive again and start to grow.
