Flowers are Dying of Heat

It looks like the Heat is finally getting to my Plants as today I saw some of the Flowers just literally burnt out. I have been watering the plants twice a Day once in Morning and once in the Evening so I really thought that would be good for the Plants. But apparently, I was wrong as the Flowers are Burning out. They are not Sulking and Falling but they are Burning out and this looks bad. I will have to take some precautions so that the rest of my Flowers don't Burnt Out and Die.
