wisteria
United States 
Can anyone tell me why 3 of my 12 wisteria seem to be dying, I have had them all for many years but three of them have gone pale and now the leaves are browning on the tips and curling up. No pests, or fungi visible at all. In two casses one plant is affected and the right next to it is lush and rapant. thanks
