My petunias start dying out after it starts getting hot here in the valley. Is there anyway to make them last longer?

This is common but avoidable. Increasing water will help and many people also choose to prune back their petunias by 1/3-1/2. This encourages the plants to start to bush out again.

If they are in containers, try moving them to a shadier location and also definitely increase watering to 2X a day.
