There's a young tree in my in-laws garden, I'm 90% sure it's a peach/apricot. As you can see in the pictures, it doesn't look healthy. Can someone point me to what may be wrong with it? A couple of notes, this is in eastern/central Europe, temperate climate, hardiness zone 6-7-ish. There's another peach tree in the same garden planted at the same time, it's already bearing fruit.
