Dormancy is when trees or other plants have gone to rest as you see in the picture above. These plant don't exprience this in summer, fall, or spring. These plants are not dead they are just at rest, so the next time you see a dormant tree dont worry. Dormant trees have absolutely no leaves. Don't ever cut down any dormant trees because you think it's dead, like I said it's not dead. Remember dormant trees are just inactive.
