It only hit 85 here today and we got .10" of rain. Wow a good sprinkling!
But surprisingly it wasn't that humid.
I shade plants, I rig awnings, so that the air flow underneath is still good, so they don't overheat. Also be sure to water them well when the temps are that high, likely needed every evening.
Hubby goes through and trims out all low branches on trees to make a wind tunnel for us.
Talk to your plants.... If your plants talk to you... Run!
