It was 103 today and my plants seem to do just fine in the heat. I have new leaves coming out all over the place, with no sunburn.
I use drippers for good soil saturation and drip sprayers for bringing down the heat and bringing up the humidity. I'll run the sprayers for less time (about 30-45 minutes @ 4-6 gallons per hour per sprayer) and the drippers for a couple hours (1 gallon per hour per dripper).
My drippers and sprayers are on 2 different supply lines, with 2 different valves, limited to 35 psi. I'll run the sprayers once every day, and my drippers every 2 days when this hot and every week if under 90 deg.
I don't have a lot of sandy soil so it stays more moist even if I miss a day or two. It seems to be enough for the bananas...
My Ensete Superbum (which I thought was dead) came back with
no water since the middle of October...in a container...in my garage with only a shoplight. It didn't start to grow til it got to 90 degrees in my garage and then pushed out some new leaves. I stripped off all the dead outer leaves, and they had wet mushy rot in them despite the severe lack of water.
