I have some locust I took down that have been laying on the ground in the way for a few years. I don't know if this is just the sap wood rotting off or if the post will be trash for a fence post or fire wood ahead suport in the future. Befor I have the boys cut them up to get rid of thought I would ask here first.

Saw the end off one, and check out the heartwood...You really need to get them off the ground quickly to cure after cutting, and take the bark off them within the first year, it usually falls right off or doesn't need much coaxing.

Build a hot fire and char 3 ft on the end to be put in the ground before fencing, and you have a 100 yr fencepost...The natural oils within black locust act as a preservative.

If you end up burning what you have for firewood, watch the smoke as it is somewhat toxic, and makes some people sick who are sensitive to it.

Yup, for best life it needs to be ricked up off the ground with plenty of airflow and protection from wet to fully air dry.

Black locust or honey locust?

Its Black, honey seems to rot fast.
