Supertunia leaves yellowing
I have a hanging basket of Supertunias in full sun. They get sun from around 10 am until it sets. The leaves on the plant are yellowing (with brown veining). It's not looking good. Could it possibly be getting too much sun? I water it well. It's in a coco-fiber basket and I water it at least once a day, maybe twice. I am fertilizing regularly -- could it be too much fertilizer? Thanks for any hel -- I really want to save it; summer's just begun!
