Just like humans, plants enjoy the shade in extreme heat. If you keep your plants in the heat or sun too long, they’ll cease flowering and can actually get sunburned, believe it or not. When plants like tomatoes, peppers, and eggplants are outside in mid 90° F, they will hold back flowering.
In order to prevent your plants from not flowering and getting sunburned, provide them with some shade during the peak of the heat. A patio umbrella or canopy will do the trick and trust us, your plants will thank you.
