I live in Phoenix and have two plumerias that have produced leavesbut they are young plants bought from Hawaii...Our heat now is over 100 degrees and next week we will reach 117 for several days...I have them on my covered patio out of the sun, and have been watering twice a week...Should I water every day? I mulched them and that seems to hp retaining water, but when the heat hit, I have a couple leaves during yellow and a couple falling off...should I bring it into the house during our hot summer? I fertilize every 2 weeks...they look healthy except losing a few bottom leaves...
