Just wondered - is it raining alot more than usual in your area??? Golden

My VV wilts at first, then gets going again later, though she's still only about 4 yrs. in the ground. My Asao did the same as yours as well (half and half).

Time and strength in the root system helps, and it does seem to happen after a lot of rain, when perhaps the leaves outgrow the roots' ability to sustain them, one theory.
