Question
Tree 2
Tree 2 loosing bark
AnswerTree 1 has been attacked by an insect called a borer. This insect will bore into the bark and wood and the tree will bled at the wound. Borer damage can be serious and will need to be sprayed with an insecticide called Merit. Check with your local nursery fro this product. Borers usually attack trees under stress so I would recommend that you fertilize the tree with 10-10-10 fertilizer at the rate of 1 lb per inch of trunk diameter scattered around the tree and watered in good. Fertilize just before a rain storm and you will not need to water.
Tree 2 I really can not tell what the cause of the death was. Looks to be some type of canker disease maybe Hypoxylon canker. These diseases also infect weakened trees. Fertilizer will help trees that may show some of the same signs also.
