OK, I'm in Yuma AZ. It's hotter than hadies. 110 right now. I have nine hibiscus planted along the back north facing wall. the soil is sandy and the ground is muched. They do not dry out and are getting plenty of water. right now I'm trying watering twice a day because of the heat. This is the second summer for the plants. they made it threw last summer OK; but now two of them are dieing. The leaves are shrivalling up and the plants look terrible. they are not really dropping leaves and they are not turning yellow. but the leaves have lost that bright green luster and like I said, are shrivalling up.

Can anyone help. I am thinking it is just to hot. So I am thinking about building a shade over them that will keep the direct sun off them.
