Routinely pruning your trees every three to five years is not necessaryistock/Orchidpoet
But it is a good idea to prune a tree with dead wood—especially when the dead branches are more than two inches in diameter.
These signs mean your tree might be in big troubleistock/Nikita Petrov
If you see mushrooms or other fungi growing on your tree, or if a big limb breaks off during a storm, have me out for a tree inspection before it’s too late. Those can both be signs of a bigger problem. If the branches of your tree are dying back from the tips, especially at the top, your tree is probably already a goner. Another bad sign: The tree goes straight down into the ground like a telephone pole, instead of flaring out at the bottom.
