Yeah, have experienced our share here a week ago at 105F, so ahead of time I have moved some close to the house, still getting some light but not too much direct sunlight. It does help. I also water/spray the root zone very early in the day before the sun hits them. I usually do a very thorough watering once a week, it is just too bone dry, right now our humidity is so low at 12%.
And summer is just about to come..
