Keep in mind:
There are lots of flowers that stop blooming when temperatures reach over 95. Don't worry, blooms will return when it gets cooler.
Rain won't take the place of watering your pots. While it's hot, water everyday. Hanging baskets might need to be watered 2 times a day.
Fertilizer will make a huge difference especially with heavy feeders like petunias. Use a slow release as a backup and a water soluble weekly.
Hang in there, cooler weather is coming!
