I live in a seasonal climate. Frost , no problem. Only 2 - high uv kills with sunburn, summer rains make them rot. Rain doesnt bother them much in autumn or spring, neither does snow.

Semps really need bright light, and they look etiolated in these pics- they were likely weakened and not growing well, and succumbed. They can take frost and snow, so keep them outside in direct light if you can. Succulents should also be watered thoroughly and then allowed to dry completely- the water was likely not reaching the entire pot and parts of the roots could have died off, so when there was water it couldn't be taken in. What was the root situation when you dismantled it?

They both look like they need to go outside. This appearance is them indicating to you that they need to be outside.

And yes, too little water can cause them to rot because the roots die and when they are exposed to water again, they don't have any roots to take it in and just soak in it.

That's great news! I hope they do well for you outside. I know you've told us before but what is your general location in the world?

Oh I just looked at your profile. Florida! Just keep them in a big pot outside and they should do well for you, so long as you don't water them while it's too hot.

What is your general location and/or growing zone? Did you just put them outdoors directly into much better light? What did you pot them into- soil?

Biggest mistake ppl make is trying to grow Semps well indoors. These are generally very easy succulents to grow but as all plants - in suitable conditions. I see them for sale in GH without any suggestion that they are hardy...They should have winter rest, and they will grow happily outdoors.

Anyone who thinks they know everything is a fool. There's always more to learn. I learned with Semps the hard way.

Semps are alpine plants and do just fine outdoors. I have them growing outdoors on rocks and pieces of wood - and I never water them. They get what the skies offer, in terms of sun and moisture. Hard conditions produce some amazingly dwarfed plants.

There's definitely a learning curve when growing succulent, they want almost the opposite of any other house plant. When I started I couldn't keep any alive over winter but now I grow most of mine from seed. Semps are very forgiving outside and looks like lots of good advice has been given. Here's one of mine in my yard putting on a good show last year, right now it's under 4ft of snow with probably 2 months left before it gets temperatures above freezing over night.

If you are using common garden soil be sure to mix a 50/50 ratio with sand for really good drainage. Then only water them once to settle the soil around the roots. Mine are in a pot out of the driveway and the rain takes care of them. Just treat them like a cactus.

FWIW - garden soil + what we commonly think of as sand = poor drainage. Even horticultural sand, which is like BB-size gravel, + garden soil = poor drainage ....... unless the BB-size horticultural sand is overwhelmingly the larger fraction of the soil - as in 85-95%.

Chad, thats a saxifraga. Close due to relation, but not a sempervivum. Flowers are a dead giveaway.

Ahhh gotcha. Thanks for the ID. I've got so many different ones scattered around the yard I never bothered to figure out what they all were, I just assumed they were sempervium.

Semperivivum has several related genuses, which look closely alike, but are still distinct in some aspects. These are jovibarba, rosularia, orostachys,promethrum. Some of these are rare though.
