shade cloth is quite cheap.
i'm sure that cheese cloth (3$)might work the same, or even an old screen , or just cut some tree branches off and use those with the leaves temporarily, i don't know
if you rig it up until foliage covers the ground, the roots may set in enough to combat the heat drought drying the soil and killing the plant
as for wind you could build something to protect it.
maybe hammer in posts and put up a ripped down piece of plywood
if heat gets worse, try supplying silica.
there's a method of making it organically, called Horestail tea. Search RIU for that and you'll get the recipe; i think it's by Cann or someone
also you could end up buying some, or analyzing your soil to see if silicates are already there.
research into silica and read about how it helps with transplants, heat and drought stress, and makes the plant stronger and more flexible.
if moisture retention is a problem, there are lots of things you could do.
just a couple suggestions! I wish it was warm like that here!
