Hello,
I live in Phoenix, AZ. My adenium is placed where it gets about 4-6 hours of full sun daily and I've been watering it about once per week. Lately, I've noticed the leaves are curling on the edges and growing upward. I left the plant on my patio for about a week during some rainy weather and the leaves relaxed and straightened out. It was only getting about 2 hours of late afternoon sun then. It looked better, but it's my understanding that these plants require and thrive with A LOT of full sun. So I'm confused about why more sun = upward growth and curling leaves. Any guesses? I've tried doing some online research without much success. I've attached photos for reference. These were taken on 9/3/18. Ten days later, it looks about the same. It's continuing to get new leaves though and nothing is turning yellow.
Thanks for the help!
