Young Silver birch still dormant?
I've planted 3 Silver Birches at the bottom of my garden a few months back. They are approx 7ft young trees still reddy brown in colour. 1 of them has seeded and now growing small leaves and foliage but 2 remain dormant. Could this be due to the late spring and they may burst in to life still or could they simply be poor plants and not going to bloom?
Any advice much appreciated thanks!
