i have petunia hanging baskets and the the foilage has gone a yellow colour can you help me

Have you been feeding? Hanging baskets particularly want a lot of feeding, at least once a week (I do mine twice a week and use the birdseed type granular pellets in the soil as well)

Plus lots and lots of water

Definatly lots of water, them being higher up mkaes them tend to dry out quicker. I used water retaining crystals in mine but still water reguarly
