tyffanie...Probably the heat at this time...It is getting to be late enough to be out of danger from curly top...If it is the virus, the lower branches often get a weird angle and hang down. The leaves get tough and leathery too. The actual top of the plant that is curling will get sort of disfigured looking and skinny...If just heat curl, the leaves and plant look pretty much OK, just upward curling....Look closely on the stems and near where curling is happening...You should see some little thrips if curly top virus is the problem. The thrips are spread to my garden from mustard weed that is widespread in a lot of our pastures...The wind carries the thrips into my garden and the lower end has already gone down to curly top...My upper plants are so huge and thriving I am pretty confident I am in the clear on those...Generally town gardens that aren't next to fields or pastures should be pretty safe.
