We have 2- 3year old red delicious apple trees that haven't started pushing out leaves yet.also, we have a 3 year old ornamental cherry tree that hasn't started pushing out any leaves yet. We live in Rocky Point, NC and had 2 frosts since easter. The small branches, especially on the apples, are brittle with a few live bigger branches. Should we worry or just wait until our warmer weather arrives ? Please let us know. Janet L.
