My Japanese maple tree is not doing so well. Three summers ago the cicadas were out so I covered the tree to protect it. Last summer I added onto my deck, right over the tree. At the beginning of this
spring we had warm weather than it was freezing weather for two weeks. Now, all the leaves are droopy and some of them are shrivled. Needless to say, this tree has taken a beating. What can I do to revive this wonderful tree?
