|I have a mimosa tree that had developed very beefy mushrooms(2)at it's base about a month ago and now the tree looks dead! I know the area has been suffering from|
|The mushrooms at the base of the tree are likely the "fruiting bodies" of a fungus that is feeding on dead wood, so once you see the mushrooms there isn't anything you can do... there are usually a sign that the tree is dead or dying, rather than the cause of death. It's impossible for me to know what caused your tree to die, so I can't say if your other one is OK or not. If it's a treasured tree, you could call in a professional arborist to evaluate its health.
Sorry I can't be of more help!
