My ten year old myrtle tree succumbed to the heavy snow in the winter with two of its three branches keeling over, leaving one rather weedy looking upright. Having consulted Jekka McVicar aka ‘the queen of herbs’, she says that this is the time to hard prune myrtle and that it will reshoot from the base. Providing it does, I will probably keep it shaped into a low growing bush as it wasn’t really the right place for a small evergreen tree.
