Linden has sparse new foliage
My 10 year old linden failed to shed the majority of its leaves this past winter and it is now July and I still have only sparse amounts of green leaves. The rest are all brown and shrivelled up. As new leaves come in the old ones fall off. However this is the first time I've ever seen this. Any advice?

I will need photos to get a sense of what is going on. And I will need some idea of where you are so I have a sense of what the weather and the soils are like.
