Hi,
My hydragea is looking really good except some of the top leaves are starting to wrinkle. It looks almost like there's a thread in the leave that is being pulled and it's forcing the leave to become gathered (you sewers can picture what I mean). I noticed the same thing on a fusia plant which is out of the sun and on the other side of the house. I also saw tiny green aphids on the fusia but I'm not sure if that is related. Help!
