They look fried by the Arizona sun. There's a couple things you could do:).

First one is repot and put in a place with no harsh Arizona sun just lots of bright filtered light. Like you've stated your porch is a good spot for them. I have lots of succulents on my porch. The ones that just aren't the biggest fans of my summer sun;). It's always best to acclimatize your plants. As you now know.

Second idea is to block them from the sun. Put a pot or other plant in front of them.

Here's an example of what I mean by putting a plant or whatever in front of the burned plant. The sempervivum is getting sun now, but once 1pm comes around the cactus will block him from the harsh afternoon sun.

1. Is definitely a Pachyphytum. Maybe P. viride:).

2. I'm not sure tbh. Could be a Senecio. I'm thinking S. mandralis:). Did they have a blue hue when you purchased them?

Watering three times a day will kill them in any climate, but they'll rot exceptionally fast in 115 degrees. Excessive heat and water are a potent combination. Bacteria and fungus live to be wet and warm, and plants won't be actively growing, so they 'll quickly rot.

I agree with Kara about the pot. Not all deserts are the same, and the Sonora desert is inhospitable to many succulents from other parts of the world. It'll take it a while to replace the leaves that are fried, but once it's vigorous again,you can gradually introduce it to more sun if you like so that you can eventually plant it in the ground. There are better species for your climate though. Native species would be your best bet if you want a xeric landscape. Most Phoenix nurseries can help you with that.

Watering will depend on several factors: temperature; whether its in active growth; humidity; growing medium; pot size, etc. Unless it's planted in straight grit like granite chips, daily water is way too often. In a standard Miracle Grow-type cactus soil, assuming full shade and some recovery time from the sunburn, watering once in 10 days is probably adequate- you must check for dampness before watering again. Wait until soil is almost dry. When it's established and growing, it'll use more water. When in doubt. Don't water.

Jessica, I think now is the absolute worse time to put them out. Aside from the record-breaking temperatures we are experiencing now, they need to be acclimated to the Phoenix temps and sun.

It is warm enough here all year round to set them out in late February maybe and let them adjust and prepare for the summer. I've found that the succulents and cacti that have survived outside (in the shade) for me end up shedding, for lack of a better word. That is, they drop a lot of leaves and pads and then regroup and produce new stronger ones that can cope with the heat.

but, I have limited experience with outdoor succulents here. In any case, right now, it would be dangerous to put anything out. The amount of water it would need would kill it before it could be helpful....

Very easy common mistake:). Lots of people think these things grow in the desert so they should be fine. Not all succulents grow in hot arid climates.

Most succulents are born and bred in greenhouses. Which block out some sun. I've been in some dirty greenhouses where I bet those dirty greenhouse panels block out lots of sun;). Then they get shipped to the store, and you buy them. You put them out in full sun, and bam they're burned. I don't mean you like I'm pointy my finger at YoU. I'm just using your scenerio as an example. It's a very common mistake.

There are lots of succulents that don't really do well in all day sun. Especially your all day sun. Even the hardiest cactus could burn if not acclimated.

Even I know better and still make the mistake;).

Whoops. This was just one day I forgot to move it in 100F weather. This plant is making a slow turnaround. So if this charred plant can do it. I'm sure yours will:).

They would be fine coming in the house on those hot days:).

Honestly as long as your porch doesn't get beat by the sun where they're in shade when it's like 110F. They should be fine there.

It's been hot here too. The weather forecast says 93F, but my outside thermometer says 103F. They lie those weather forecasts!

Best of luck, Jessica. It's definitely a new challenge growing things here:). At least you weren't silly enough to put a regular houseplant out there in the sun, like some people I know:).

Lauren did the houseplant just turn white or shrivel into nothing:)?

There's something else to consider, as well -- time of day. Jessica mentioned "5 hours of direct sun". But what time of day are we looking at here? Even here in the north, there is a significant difference between direct sun from 7am-noon and noon to 5pm. (Even greater difference if the plant is under a tree or other shade source such that the plant receives direct sun early in the morning and again later in evening.) So in addition to hardening off the plants, placing them where they will be shaded during the hottest part of the day can make a big difference as well.

Paul: there is no such thing as shade or time of day when the sun is hottest right now in Phoenix. It stays hot all day into the night and the sun is ferocious. this is just not the time.

even after the sun starts going down, it is oppressively hot. I mean, my dangling earrings burned the side of my face hot. Like, you can't even touch your own car door hot. Like, you can die within 30 minutes of being outside in the shade hot.

hot. Really damn hot. I couldn't even pick up the quarters in my side tray to put them in the machine for air for tires yesterday. Then couldn't touch the air screw cover thing to hook the hose up to the tire. Then burned hand on hubcap.

I am ranting now. I just want people to understand how hot it is here right now.

I lived there 30 years, Lauren. I feel your pain. I remember one summer when the intersection of Indian School and...something had to be closed because the asphalt had softened so much in the heat that cars were misshaping the roadway. And people in the East will say, "yeah, but it's a DRY heat!" LOL. They just can't imagine it. Godforsaken climate. Your overnight lowes right now are what, about 90-95?

I bailed out, and only ever returned when I had no choice, like caring for my dying father.

And the monsoon and 60% humidity are coming soon! And it won't cool off substantially until October.

You can come up here to the PNW, Lauren. Nobody owns air conditioners. The clouds didn't clear this year until 2 days ago, and we're having a mini heat wave of 93, 100, 93 and everyone thinks the world is ending. Clouds are scheduled to return on Tuesday. ;-)

Oh, and there's some nut job here in Eugene who drives around in an entirely chrome Magnum- chromed instead of painted. Can you imagine a chrome car in Phoenix? It'd be like some kind of death ray machine.

Oh Kwie, God bless you for that message! Lolololololol! Somebody understands!

You know, all of the natives and older folks are saying that this is pretty exceptional heat in these past two years. Our overnight lows here in the center city are about 97-99, slightly lower in the foothills.

things are melting randomly and people are acting weird, weirder than normal. Lol.

How I would love to visit your lovely clouds and temperate weather. But, to add insult to injury, the planes are no longer flying out regularly because it is too hot to fly. Yikes.

Too hot to fly? That sounds like something made up by the city council to keep everyone from fleeing the city. ;-)

Hahaha, I read where they grounded the planes because it was too hot. Last year when it was 100 plus or minus a degree of two, over nearly a week, I thought my tires were going to melt. I didn't like driving in it.

Kwie, I want to move to the PNW!!! I would love cloudy rainy days. I'm allergic to the sun, lol.

I used to love cloudy, rainy days too, but the PNW has them like Phoenix has heat and sun: a relentless, mind-numbing monotony of them.

Still, I wouldn't trade this tedium for the misery of a Phoenix summer.

Yes, Kara, it was really too hot to fly! But what you said makes sense, because truly, most of my colleagues leave for the summer (as do I). Add in the visitors at Las Vegas who don't know what the hell hit them, and people would be crowding the airports trying to leave!

They would be at the airport counters like, "I don't care where. Somewhere cold. Just pick a cold place and give me a ticket to there."
