I could have written your post as I did the exactly same thing, moved it outside to brighter light thinking it would be ok. When I saw all the yellow leaves, I brought it in and watered well, and it seems stable for now but lost a lot of leaves. The photo shows it now, but it was much nicer before.

As I was reading your post, I thought, "This sounds like me!" Then when I saw the black metal table top in your photo, I really wondered if I had posted this in my sleep or something.

Haha, I saw that and did a double take. Adenium in a terracotta pot on black mesh table! But for a slight difference in shape of the pot and the caudex.... OK, so I am not the only who thinks heat couldn't hurt an adenium.... Luckily, the weather has cooled so I couldn't give it too much sun too soon even if I wanted to. The conundrum is we don't have long enough of a summer to afford to waste a few days of sun exposure willy-nilly. It would never bloom otherwise.

Many thanks, Kara. Will do.

I repotted mine very recently. I got it from HD and it was in a 6 inch plastic pot in a mix of peat and perlite, mostly peat. Luckily, the roots were pretty healthy. I moved it to a much smaller 4 inch terracotta pot with lots of perlite added to some of the previous mix, and added some lava rock and some bark. I water only when the bottom of the terracotta pot does not feel damp. I have lost a few adeniums to rot so I am just not brave enogh to risk watering generously. I do fertilizeavery few weeks.

Is it doing better, not having yellow leaves?

Yes, the pics I posted were after all the yellow leaves except a couple had been removed. Those yellowed and fell off within a day I think. Since then it has had new growth and no further yellowing. I will post a pic in the next post. I am giving it high phosphorous fertilizer intermittently in the hopes of inducing buds. Greedy me..

Here it is. It hasn't been very long since the incident so I doubt the growth is noticeable but it appears to be a happy plant imho.

My first thought when I saw the above pics was ”WOW!”, your Adenium looks noticeably happier😀.

You didn’t ask, but in about a month or whenever the temps start cooling down, keep by a warm sunny window and dry till spring.

I used to be really intimitated by Adenium obesum, but I think I’ve figured out what they like and don’t. My first Desert Rose was about a 10 yrs ago. I bought it from QVC because they’re beautiful plants, and the host and guest made it sound like they’re super easy to grow. Well that poor thing froze to death that winter. Definitely not cold hardy!

Goodluck!

Kara, I remember seeing “desert rose” on QVC years ago too. I never got one through them. I think they were at least $30, maybe more. Saw one at a C/S store for $15 and jumped on it, so thats the one I have.

Getgoing, glad your plant is recovering. Looks great, so green. Mine is recovering as well, tiny bit of new growth after potting up and raising up as per Kara’s suggested treatment. Also more water. I guess adeniums aren‘t as forgiving about water as succulents/cactus. I brought it back inside. No blooms this year but thats ok, I’m just happy it is alive.

Socks, good that you repotted it. I have mostly kept it indoors in the sunniest window. It hasn't been very warm outdoors for very many days and it can get much warmer indoors at least next to a closed window. Don't give up as yet. Has it bloomed before. Mine is anew acquisition from HD so I don't know its history but it seems mature enough to bloom. Keeping my fingers crossed. I did kill my previous one that I bought bare root and several seedlings so I am also glad to have it alive but then it hasn't been very long in my care. :)
