Based on where you live, here's how to get cold-sensitive South African succulents---like crassulas, euphorbias, senecios and aloes---through a North American winter.

Coastal CA from the Bay Area south

Your climate is more similar to South Africa's than anywhere in the US. You banana-belters don't get frost, and winter humidity and rainfall are low, so simply make sure your succulents get good drainage during storms.

CA Inland

Welcome to my own imperfect climate! At 1,500 feet in the foothills NE of San Diego, frosty nights follow rain. When temps are forecast to drop below 32 F, I drape succulents with frost cloth or floating row covers.

You'll need to overwinter all but hardy succulents indoors---perhaps your basement---or inside a climate-controlled shelter.

Frost hardy succulents Most sempervivums, many sedums and a few other types of succulents (generally not from South Africa) are frost-hardy down to -20F (Zone 5). Use them to add vibrant colors and winter interest to rock gardens, containers and more.

Desert Southwest

Keep your South Africans on a covered patio, and embrace (well, not literally) succulents better suited to your region, such as cacti, agaves, dasylirions and yuccas.

Southeast

Plants from dry regions don't like damp, humid climates. This excerpt from Designing with Succulents (2nd ed.) explains those suitable for your area.

    Hi Deborah, I have some deep purple/black spots on my Pachyphytum Oviferum and I can’t figure out what is wrong.. The leaves are plump and firm but this discoloration seems to be spreading. The plant gets lots of morning sun. It’s been anywhere from the high 20s to 40s at night but not under 28 so I thought it would be ok? Now I wondering if this is happening because we’ve had some severe shifts in weather where it’s low 40s at night and then 78 in the day. The newest growth looks great. Because the leaves are so plumb and firm I don’t think it’s a watering issue. You can see pics on my Instagram account. PS – your mealy bug post was great! Thanks!

      Hi Tracey — Black spots that originate from the stem of the plant (i.e. from internal causes) are usually rot. If black spots are on the surface of the leaves and not near the stem, they could be caused by a number of things, but from your description, I’d guess sunburn. Pachyphytums, from Mexico, do best in an annual temperature range of 50 to 80F. The good news is that each healthy leaf contains all the moisture and nutrients needed to start a new plant. To start them, gently twist off the leaves and lay them atop (dry) potting soil out of direct sunlight. From the stem end, new little threadlike roots and beadlike leaves will grow. Once they drain the leaf and it withers, plant them.

        I am a little confused because your video with Tom Jesch said that Pachyphytums aka moonstones did well with both high heat and low temps…but ok, I’ll go with this latest info. Thank you.
