This is the first time I have ever had succulents, this past summer for some reason I seen these plants and had to have them. I have them planted in huge planters outside, and some in the ground and so far they are great. But winter is here, how do I keep them alive over the winter? Will covering them with plastic or a blanket on freezing nights enough? Or do I need to bring them inside?

Unfortunately, none of those plants are frost hardy. A sheet of plastic will cause rot. Maybe you can devise something that doesn't lay on the plants, like a little tent, that you can put a light bulb or a candle in. The light will have to be a halogen light as LED and CFL lights don't heat well.

I agree with Daisy. I'd just take cuttings of the ones you want to save, and grow them indoors for winter.

I agree with the above. However, the succulents in the last photo will probably die down and regrow in the spring, including the purple heart plant. The aloe will die if it gets frosted or frozen. You may want to dig it up to bring indoors. (I keep mine under lights in my garage).

Depending on how cold or much frost you get in your area, you may be able to keep the pot under cover (porch, wide eaves) and cover with a blanket at night. If you have precipitation, place a piece of plastic (old shower curtain) over the blanket.

Surprisingly, most succulents can survive cold temps, as long as the roots are not wet. Over the last couple of winters, I've kept frost cloth over mine which are sitting under the wide eaves of my rooftop. If it gets colder, I'll place a moving blanket over it. But if temps get into the lower 20s or even teens, I'll have to place them in the garage until it warms up again. BTW, you can grow them under lights in a garage, if you're not able to bring them indoors.

I have brought my purple heart in a container inside to winter indoors. You can cut off starts or dig it all up, I really enjoy how big it gets over the winter. Next spring I will repot it with some pink verbina to make a nice big basket. I think the aloe is your most fragile, but it looks so nice, I would sure try to save it.

Thanks for all the info, we have had a few 32 degrees nights in the last few weeks, and they are fine. Looks like I will be digging them up and bring then inside, I have daylilies seed and seedlings in my spare room under some lights so I can find a spot for them in there.
