    1. Unfortunately there’s not a lot you can do once the bark has already been damaged. Be sure the trees have plenty of water over the summer, as the bark damage will inhibit their ability to move water up from the roots to the branches, buds, and leaves.

  2. A deer just broke the main stem of my apple tree about 2/3rds of the way up from the ground. The tree stands about eight feet tall. I attached a splint since the branch was not completely broken. What should I do?

  3. I just planted about 6 8 ft Norway spruces and some of them are beginning to get brown-yellowish at the tip of the needles. We have quite a harsh winter this year as temps have been consistently in the single digits and negatives. Are these trees going to make it? Lookin for any advice I can get to save them. Thanks
