I got a 5 yr old Korean hornbeam that was dormant when I purchased it. As it has bloomed I notice there are a few limbs that look dead and nothing has come from them, no sign of buds at all. I have seen other trees with what appeared to be dead limbs with new growth at some point. My tree has a good many leaves and some buds continue to appear, but not on the limbs I am speaking of. I would think something should have shown on the limbs by now. Should I just wait and see if something comes out later? Or are these dead looking limbs, "dead weight"? and need to go.

Thanks,
ML
