Misting in extreme heat
I live in the Phoenix area where it is HOT and have two rapidly growing plumeria in pots under a south facing pergola where they only get partial or filtered sun. I notice that the leaves that get the most sun, burn and get dry (crispy) to the touch but the plant seems to be healthy, has plenty of leaves and is flowering. I usually water every morning when it is over a 100 degrees. We recently installed a misting system to give them some added humidity. My question is, when is the best time to mist? I've read that you should not mist when the sun is out because it causes the leave to burn but I already have leaf burn and I thought the added humidity would help. I also read that you should not get the flowering area wet as it will damage the flower buds. Any ideas on how best to mist my plumeria without causing any damage?
Early morning or early evening would be the best time.
