can a female locust tree be sterilized to prevent seed pods?
There is a chemical called dikegulac-sodium that can be applied to reduce or eliminate seed pod production in locust as well as other trees. Several products may be available, though availability may vary by state. Here is more information about managing nuisance fruit:
i have been taught that a problem with very mature locust trees is that they can become a safety hazard. there is much dead wood in the one growing about 25 feet from our house, had a friend years ago that the city made her take her tree down as it was at the curb in a city block. should i be worried?
Black Locust Trees can be an issue.
The trees are used infrequently as landscape trees for a few reasons. First, although the wood is strong, branches are brittle and prone to breakage in high winds. The trees also have thorns. Black locust trees are very susceptible to attacks by the locust borer, which often prove fatal. The trees are more often used to control soil erosion or as a timber tree.
I had a large Locus tree cut down and ever since, these little ones keep popping up all around my yard, in the same places. I keep spraying, they die off and pop up again. Please help.
If you didn't poison the cut stump immediately with a systemic herbicide that kills the entire root system, then the tree has gone into survival mode. The growth popping up in your yard is probably suckers off of the lateral roots that are still alive.
At this point there is no easy way to eradicate the suckers. you have to chase them weekly as they appear and cut or spray them, probably for a couple or three years until they don't come up anymore. Don't let them grow at all or they will photosynthesize and feed the roots.
The only other way is to dig out all the lateral roots.
In SW New Mexico. Our small locust tree if eight years has a trunk that has gradually grown black!
No photos came through so can only provide best guess. It could be natural color of black locust, or it could be sooty mold growing on honeydew secretions from an aphid infestation. The mold is not harmful, but the aphids are sucking insects that can weaken the tree.
I have 4 young locust trees all the same age and treated the same. One lost all its leaves and I thought it had died for some reason. Then it started sprouting all new leaves and appears fine?
Some type of physiological stress like water deficit could be the cause.
I hope someone can help me identify this tree, even though this is a gardening site. Is this a "Honey Locust" or a "Black Locust"? I am adding photos. I do not see thorns on the trunk, but some on very small branches. Also, I have included a photo of leaves
It does appear to be Gleditsia, but not the Honey locust. Probably a more ornamental cultivar with a low thorn count.

We have been required by our landlord to pull up or destroy the black locust suckers in our yard, but I would like to save some of them by transplanting to a container. Is that possible? Please advise. Thank you! (Below is link to one I've pulled up that is still connected to the tap root:) https://photos.app.goo.gl/TuJAiuxAxjYijZz78
Sure, you can grow trees in containers. This one will need a very large one, but it can be done.
