large knobs on 40+ year old fruitless mulberry
We have had a branch break off our fruitless mulberry. I know this tree is over 40 years old. The knobs seem huge. We have been in a drought for a couple years. The tree gets pollarded once a year. What can we do to keep the rest of the branches from breaking off? The tree is right next to our fence. Is it too old, or the drought, or the way it has been pruned all these years? Any ideas on what to do? This tree is at my 76 year old mother's house and I am trying to prevent any more damage.

One of the main declines in health of a Mulberry Tree is lack of water.
They are considered to be heavy water drinkers and drought can cause stress on a tree.
Mulberry decline can be seen as wilting, yellowing leaves, loss of vigor and that can cause limb damage and the eventual death of the tree.
Lack of a fertilizer schedule can also add to a trees decline. Once a tree has entered a decline, it's can be difficult for the tree to recover.
Your tree has developed a large gall and it can be caused by fungi, bacteria, insects or injury to the tree.
Your tree appears in very close proximity to structures and I would suggest you have this tree examined by a qualified Arborist to determine it's safety and if your tree is able to be saved.
