I normally do any potting up in spring onwards not at this time of year. I was forced to dig some plants out of my garden due to them being in the way in a new project I am doing. I have dug up Erysium bowles mauve and other perennial wall flowers and some alpine perennial ground coverer's. I wondered since I potted them up if I ought to trim back the wallflowers particularly(perennial ones) . I have put them inside the greenhouse since its late in the year. A good amount of leaf growth is still on them but its dying away from it now I've put it in a 3 L pot. Do you think I should cut back this years growth 'only' back to the main stems so the plant can focus on rooting a bit before winter. The Uk is currently an average of 5-7 degrees C in November at night. Thanks for your help.
