Becky,

That's a shame! There are cold-hardy succulents and cacti, but the majority of them, as you found out too well, are not.

Do a visual check, and if there are no bugs, no treatment is necessary. As to the diminishing light, I can't say - mine are put inside with access to some sun. I try to clean them up too, as needed, but other than that, no, nothing to do. I don't think the weaning them off light is something needed, you just want to do so when they're drying - I wouldn't put a plant into dormancy while it's been watered. Winter's late this year- I'm still bringing them in myself.

You also may find out what you have in your collection - even in the winter and with low light levels, many succulents will grow (some even have winter as their primary growing season) during the winter.

Thanks cactusmcharris! We are also still having unseasonably warmish weather: 70s daytime and no lower than 40s at night so I'm not even considering moving them yet. But if I needed to start doing a sunshine withdrawal this would be the time to start. Some of these are heavy pots so I'm pleased to hear I don't have to be moving them around.

So if I wait till it starts hitting 30s at night before bringing them in for the winter that should be ok? What should I plan about watering?

As for what I have - I have no idea. In the spring I went around to places like Home Depot, Lowe's, grocery stores, etc and bought tiny little things I liked the looks of. None of which were labeled with more info than "succulent" ;-) Nothing in bigger than a 3" pot. I chose them based on shape, color, etc. and potted them up. No consideration for individual needs. Some have way outgrown their pots but I'll wait till spring before repotting. If they do as well under indoor winter neglect as they've done in the summer neglect I could have a serious repotting effort ahead.
