temp in mid 80s here
My RM 18s are in full sun
If I didn't water daily( in absence of rain ) they would die
You cannot over water them in east texas
Find what works for you , expect to kill a few trees on the way, and don't give up
" Chestnuts aint' easy to love and they're harder to grow"...

Sawtooth,live oak,white oak ,DCO,chinkapin oak
All had radicles
