variegated/turning green, Rosa sinensis
I work at Tucson Botanical Gardens. We have a variegated hibiscus, Rosa sinensis that receives a good amount of filtered sunlight throughout the day. The leaves are green with splashes of white. It's in a large clay pot. I read another post related to my question but would like further information. The newer leaves are emerging green with no white splashes. The previous post said that lack of sunlight and too much nitrogen could cause this. So, right now it's 110 in the shade and I'm afraid to move this plant to a sunnier location. Full sun exposure in most places in the U.S. is entirely different than full sun here in Tucson. Also, what type of fertilizer should we be using on this plant to encourage more variegated leaves? Any help would be greatly appreciated.
