Did you graduate it to the new area? That is quite a jump, like taking one from indoors directly to full sun outside...would never dream of it myself.
Can you place a lawn chair or some other form of diffusion over it?

At the time I moved it, it couldn't have been much of a shock. It was early spring and days were a lot shorter. It was getting some direct sun before, now it's getting a lot more, but it's had plenty of time to adapt by now. I'm noticing some other aloes that look like they'd rather be getting more shade, particularly the kind that's called a desert lily or something like that.

I'm beginning to suspect aloes are not the best choice for spots that get unrelenting California sunlight. I have some A. ciliaris in deep shade that look healthier than the ones on my hillside.

Looks to me that the roots have dessicated or rotted, dig up and check. I would keep it in a pot till it gets bigger or throw a piece shade cloth over it till it recovers. Majority of Aloes can handle full sun as long as they have root systems to keep them hydrated.

Without a doubt caused by a lack of water. A.ferox is a full sun Aloe-not sun shy. The pic is a little blurry,but the soil looks like death valley cracked. Figures a tuft of weed grass is hanging in there with a deep root though..

You are so right, they grow in hot African sun on hillsides full of rocks. Follow the above advise, these gals are good. When the leaves curl up it is giving you a message. It may not be getting water all the way to the root ball, perhaps the soil is bad, Young plants will not adapt that quickly. Location is every thing. Soil is the next best thing and don't forget the proper water regime this time of the year. That plant is depending on you. Use a pencil/chop stick for a water meter. Norma

Thanks for the advice all. The soil IS horrible but I don't know what I can do to improve it on a steep hillside. The slope also makes water run off quite fast as well. Some of my succulents don't seem to mind that at all, but others are not growing half as fast as I expected. I'll try to get more water up there, but the aloes may just have to hold out for winter rains.
