Bing cherry tree, neighbor wants me to cut it down.

Question: Bing cherry tree approximately 25 feet tall.
My husband bought it about 8 years ago from grocery outlet, it was supposed to be a dwarf.
This spring 2024 we had many ripe cherries for the first time.
For the past two years we had lots of cherries but they fell to the ground before they got ripe.
The tree is 18 inches from the fence line.
My neighbor is concerned that it will lift up her cement walkway.
The cement walkway is about 4-5 feet from the base of the tree.
Also she is concerned that this tree will send up shoots throughout her back yard.
Should we be concerned about the cement walkway being damaged?
Will this Bing cherry tree spread into her backyard and sends up shoots?
Thank you,

response: Nancy: Both lifting up the concrete walkway and sending up shoots from the root system are quite possible.   Shoots depend somewhat on the rootstock the Bing is grafted to. Some are more likely to push up shoots than others. But there isn't an easy way to determine which rootstock your tree has.   Cherries often do produce large roots very near the surface. Again, rootstock varieties play a role but also the soil type makes a difference. Cherries are not fond of water-logged soil and the fairly large semi-surface root systems here in western Oregon are a response to that.   I wish I could offer you a better answer.

response: Dear Mr. Chip Bubl,   Thank you for your quick reply. Not the answer I wanted but it is the honest one. So, now I am thinking that I could cut just below the level of the fence or shorter, but anyway I would like to keep a stump. Would that be possible without making problems for neighbors yard.   Thank you for your input and advice.

response: Dear Nancy:   I wish I could offer you the hope that the tree wouldn't send up shoots but likely it will send up more after being cut!  Removing the stump down to the soil won't stop the roots from sending up shoots.   The only way to prevent it is to treat the stump surface with an herbicide right after cutting. The herbicide will  travel out to some of the root system but perhaps not all. The larger roots near the base of the trunk will generally be affected but ones further out may not be. At a minimum, it would stop the roots from getting bigger and, working with your neighbor, treating the shoots as they appear.   This month is the best time to do it as it starting to prepare for winter but nowhere near dormant yet. The person you hire to cut the tree down should be able to advise you on how to treat the stump.  It would be possible to keep the stump after treatment but it will, over a certain number of years, start to decay more rapidly. I hope this helps. Chip
