How do I care for my potted petunias?

Do you have a issue with them?

All I do is water them often and pinch off the dead flowers. They really aren't difficult to care for at all. Good Luck!

Water and be sure to deadhead when the blooms die to keep them blooming

I deadhead almost daily and when the stems get leggy I trim one third of the stems back to about the pot edge every week for three weeks. That way you always have blooms until the trimmed stems send out new shoots and lots of new blossoms. I do this throughout the season ensuring flowers until the first frost. If you don't take off the old blooms the plant will go to seed and stop blooming. Be sure to pinch off the little stem beneath the flower where the seed pot forms.
