Pruning a Cornus alba 'Elegantissima'
I've got a Cornus alba 'Elegantissima' (Red-Barked Dogwood) and have noticed that the stems are no longer red near the bottom to about a 3rd of the way up. I've read that to retain the red colour you should prune the stems right to the ground, but would I be correct that it is now the wrong time of year to do this? Or should I have a go? There are leaves on the plant now.
Is this something you have to do each year?
