Last summer wasps built an underground nest in a flower bed. This spring, two trees close to where the nest was built appear to be dying. Is this due to wasp damage and will they rally or should they be written off?
how big are the trees? Anything more than a tiny sapling would be unaffected by a wasps' nest, they're not that big and don't expel poisons. Only humans do that.
what are the trees? can we see a photo?

Sounds as if it must've been quite dry down there.
As (I hope) you can see from the photos, the photinia on the right (In the second picture) has plenty of flowers but virtually no leaves while the one on the extreme left of the picture has abundant leaves. The first photo is a close-up of the photinia plus a small berberis (extreme right) which also appears to be suffering leaf loss. Wasps (the underground nest was between the two affected shrubs/trees) or just nature?
I think you need to look elsewhere for the cause. A wasps' nest couldn't harm a shrub like that.
Thanks for your input. I guess it's just one of those things and the tree might have to come out.
It's quite a narrow part of the bed ....... maybe they dried out last summer and autumn - I can't imagine wasps nesting in a damp area ... and we've had a dry spring too.
