Petunia yellowing

Hi, one of my petunia's in my hanging basket, leaves are yellowing slightly. Wondering what's causing it?

How often do you feed it?
There's quite a bit crammed in there - it's going to need feeding and water often
Looking lovely though

Knowledge is knowing that a tomato is a fruit.
Wisdom is not putting it in a fruit salad.
Thanks for your reply. I feed the basket about once a week, should I do it more often? ?
Looking at the leaves, probably. Try every 4-5 days with a tomato food or e.g. miracle grow for a few weeks.
If you have any epsom salts, 1 teaspoon in a litre of water would probably help. It would only need this once, but not at the same time as you feed it.
Petunias don't like to dry out, geraniums do like to dry out a bit - always a problem when planted together - as I do too. If the petunias dry out too often they get mildew and look horrible, so best to keep it slight;y damp, but not wet
