    Many annuals begin to get a little leggy this time of year. Try cutting about a third of the legs back by half. When new growth begins, cut another third and so on. This should rejuvenate the looks of your petunias.

    There are a couple of possiblities. Your plants may need thinning because they've put too much energy into spreading, or your plants have become sterile. Try thinning them out.

    If you have a lot of heat and these are in full sun, they will struggle. While petunias are a great early season plant, for those of us with hot, dry summers )?_, they usually poop out. I have some friends who have good luck here with Wave Petunias but I don't. If you want to try to save them, shear them back to four inches or so. Water well and make sure they do not dry out too much. Baskets are hard to keep wet enough. Only after watering well and while soil is wet, fertilize with a good water soluble fertilizer per directions. Do this every two weeks. They may come back and give you another flush of blooms. I just consider them "worn out" and replace them with something that can take the summer conditions.

    You can deadhead petunias to encourage more bloom. Just gently pluck off the spent blossoms.

    It is possible that the soil became dried out. When this happens, some potting soils can actually start to repel water. You have to soak the pots underwater for 10 minutes or so to rehydrate the soil. I suspect that this may be what happened, which resulted in the plants not getting enough water and dying.

    Overwatering certainly sounds like your problem. You should always allow plants to dry out some between waterings. Check the soil beforehand by inserting your finger and if it's moist or wet, do not water. If it feels fairly dry, give it some water.
