Sure, they'll survive. It will help them if they can get some root growth down as you "ease" into Fall and Winter. Sempervivums are generally considered cold hardy down to -30F. I don't think you'll have to move them into the garage for some time yet. But I really don't know the dynamics of potted plants in such cold weather.

Your biggest danger is rot which occurs not because of cold but because of moisture. Not nearly as bad as cactus though. When you transplant into the new pots, keep each plant's crown up plenty high. Maybe even raise the plant up an 1/8" relative to the new soil level. The worst danger is the bottom of the plant sitting on top of soggy soil.

Give some solid moisture at transplant time but just the tiniest bit of background moisture in the soil for new roots to establish. Excellent drainage is of course recommended. In subsequent years you will allow your pots to completely dry between waterings. But for establishing in a new pot, they need a small amount of moisture. Don't kill them with kindness.

Thanks, thats great. I have semps and know winter is not a problem (besides the wet). Its just that, I was worried if they dont have time to root, would they die of the cold. I have my own succulent soil that I grow all my cac and suc in, well draining. Lets see how it turns out. I think Ill have to cover them up whenever it snows though.

Are you getting them with roots (I would think so)? So they just need to establish themselves and don't need to start growing roots from scratch.

tcstoehr said everything I would - drainage, drainage, drainage. I grow many in all kinds of containers - plastic, concrete, terracotta and even old, glazed bonsai container. I wouldn't put them in garage, they still need some moisture and what if you forget about them? (maybe it's just me :) that does that!)

Hi Rina, ever since I moved to a house Ive lost all interest in cacti and succulents. Its actually after the spiders in my back yard that got rid of the mealies I stopped caring for my plant. Its been many months since Ive visited here.

I am hoping they have roots, Im getting mother with chicks and pups. Pups wont have roots but I hope mom does.

When you say they still need moisture, what do you mean? Should I let the pots get snowed on? This is what Im not sure about. I think the pups I got last year died because they dried out during winter. They also developed a few roots as well.

When should you stop watering them?

Rob

Thanks Rina, those semps have beautiful colours. Did you buy them online from Canada? I really wanted to plant them in the ground, but there just isnt any space here.

Rob

I hardly ever water them, seems that rain is enough. Sometimes, in the middle of summer if it doesn't rain for more than 2 weeks, I water. But almost never toward end of summer.

I never bought any plants on line, if I see one I really like, I pick it at store. And if I see some different ones at friends house, I ask - there is usually plenty of chicks to be given away. This year, I bought just one pot of semps and eventually divided ans potted them separately; they are still quite small but growing well - lots of tiny ones went 3/pot (I have at least 20 of those), some larger 1/pot (about dozen) and some in larger saucers - just snapped these, but it is dark and raining...

Here they are being washed and separated:

I found photo of saucer above, couple days after potting - chipmunk dug them all and I had to fix it. I added few larger pebbles that are visible in tonight's photo above.

Nice, so far Ive only seen the cob web type or the usual green with a bit of red, so boring. For work, I travel around Toronto and Ive seen many many houses with hens and chicks, its the same story, cob web or the green with a bit of red. Nothing like yours or a tri-coloured one. There was only one house so far that had a rock garden with Agave, Yucca and a few other varieties, I should up the pics here. I just loved it. Too bad it was early in the morning and I didnt want to knock on their door just to compliment them.

I think I need to look harder whenever Im in HD, Lowes or Rona. My local nursery is huge and good prices, they have hundreds of semp pots but again, same story, just 2 types. They had very nice agave though.

If I may ask, which nursery is it?

I don't remember where I got most of them since it has been few years. The last one was in HD in Newmarket.

Here is nice 'marbled' one...I didn't keep the name (or maybe never had it?).

Harry (hablu) has lots of beautiful semps.

Ill be getting them from US, SMG Succulents.

Hi guys, just planted them yesterday. Only a few have roots where as the rest are plugs. I did not water them either. Maybe next week. In about two days overnight low is going to be around 0c so Im kinda worried. Maybe put burlap or something over them for overnight?

For soil, I have large gravel at the bottom because Im low on mix, have my own mix (cac soil + pea gravel + lava rock) with Flourite top dressing. Most of the semps are just sitting on the soil and flourite. The mix is a little wet though, which is a cause for concern. Unfortunately, Im flying to Florida so I can ask my dad to cover them up (we need to cover the fig tree as well).

I have ordered from SMG succulents before, and I like them a lot! They are in Eagle Creek, OR, and they specialize in cold weather succulents like these. It gets very cold up there! They do a grab bag of lots of cuttings of semps and it's very very affordable with great variety, I'm guessing that's what you took advantage of, I certainly did!

I am just planting some in the ground right now in central ohio, so mine are not established at all either... I feel like the fact that these are in pots may make them more susceptible to the cold- so covering at night might not be a bad idea. But mine, just because they were so affordable- it's sink or swim!

Yea I ordered a few mother/chicks and the rest pups. I have no space at all to plant in the ground and I have terrible clay soil. So for the next few days, in the evening covering them is a must it seems.

You may lose a few but I think you'll be surprised how many make it without any issues.
