Leaves going black


I moved my succulents out in a little cheapy plastic greenhouse. Now a few days later I'm seeing some of the leaves going black. Even on the pothos. When they were inside, I had two different echeverias suddenly get wrinkled, dark, soft bits on their leaves – then they died 😢

The lighter colour plant (sorry, can't think of the name now) got quite etiolated in the house (I had grow lights around all of them but I don't think they were strong enough), and then when I took it out I dropped it so a lot of the leaves fell off. (It's the kind of plant that drops its leaves if you merely look at it funny, anyway.) I did gather the leaves and I put them on a tray to grow roots so I could propagate them, but they are developing the same dark spots.

Now, it is still cold at night here in Scotland (and it's due to get even colder this week, down to 2C, so I might have to move them inside again for a bit).

Could the dark bits have appeared because of the cold? Or is it some sort of disease that has slowly spread around?

My fishbone cactus and Thanksgiving cactus and a couple of other plants that have been sharing the space seem fine so far.

I'd be really sad to lose the Crassula arborescens, as it looks so nice and I've had it since it was tiny.

    They’re cooking; getting burns due to the heat and/or light refraction of the plastic cover. These plants need airflow.

    Even though succulents are desert plants, they will burn when you bring them outside. I bring mine out in april here in germany and have them under a shade cloth for the entirity of may. After that they get the full sun. I don’t think cold is the problem. I had some echeveria live in -7°C weather. Crassula are less hardy though. It helps when the plants have a roof over their heads.
