Apologies. I've just realised that I've got the two types the wrong way
round. Ours is common walnut which is Juglans regia and as Roger says it
is Juglans nigra which prevents other plants from growing near it.

The effect is supposed to be real, but often overstated. It affects
some plants a lot and others not at all. So what else is new?

My mother had one, and lots of things grew under it, but I cannot say
what would have died if it had been planted there.
