There's a technical term that I cannot remember, which is applied to trees that change the soil composition where they've grown, so that even after they've been removed, nothing will grow there. Would someone please refresh my memory?
term for trees that make the soil inhospitable so that nothing can grow there after they are removed

Possibly you are thinking of allelopathy, which is a general term for plants poisoning the soil around them.
Juglone, associated with trees in the walnut family, is an example of an allelopathic effect on the soil.

If you do have a walnut and you want to grow something underneath it, raspberries tend to do well under walnut trees, even black walnuts.– EscoceSep 12, 2019 at 2:08
