A S, Most of my well established plants are all in my Patio. We have pretty much the same temps. My plants all do generally well, but I'm now more concerned about the heat with high light than the cold. They show stress colors in the night, but as the day warms up, they do fine.

So far, I've burnt mostly my Crassulas, some echeverias, and forst 1 Crassula Jade. We had a freak frost weather a few weeks ago, and that was the threshold for my plants. I think as long as it doesn't go into freezing point, the plants should be ok.

Now all my plants has shade, so I don't fuss with them so much, other than keeping them well hydrated because my mix are generally on the drier side.

I am surprised your plants burned - is the sunshine so intense already in your location? - I am sure you acclimatized them.

Hi Rina, yes, I guess they are also on a high level by the patio. I burnt a few of my Echeverias and couple of my jades, including my Hummel, Gollum. The shade helps a little, especially from the rain, but sunshine is probably very intense during the heated afternoons.

Wow that's crazy that they got sunburnt already!

I think to be on the safe side, I will wait until temperatures stay around 50s for lows. Hopefully that will only be another week or so!

What about cuttings? Do you guys think putting them out around same temps is okay? Or should I leave in warm room inside until I can see plant let's forming?

We have similar temps now too. About 3 weeks ago, when the temp still dipped to 40 and occasionally below, I bought a portable greenhouse for my collection.

I put a heater with a thermostat in there too. It's located on a raised patio with sliders, so it's easy to get to. I also use an old fan to keep the air moving.

I also put a digital thermometer in the greenhouse, I got it at Walmart for about 10$ There were 2 parts to this thermometer. There's a sensor that stays in the greenhouse and the 2nd part is a little box that tells me the current temp.

I set the heater for 55 degrees at night, & open and roll up the shade fabric, zippered door during the day.

My issue is also the sun. Burned my superbum right through the thick plastic shading of the greenhouse. A couple of others were sunburned also but after having identified the hot spot, I've moved a few of them around & now it's all good.

Before the greenhouse, I lost 5 of my largest Jade trees to frost. There was a freak 25 degree night time drop & it caught me off guard :(

I move the thermometer sensor around the greenhouse to get an idea of the average temps in there. I want no lower than 50-55, but no higher than 70 if I can help it until we have no more threat of frost. Then, out in they come!!

I am sure you'll be safe with 45-50*F overnight. I would keep them all outside if I had a GH - at this time of year, I don't think plants will get a cold damage while in GH. But I also think they should be acclimatized not to only light, but temps - especially if they were kept warmer indoors. Crassula ovata is supposedly hardy to temps in 30*F range - I never tried that low :) Most Haworthias - supposedly down to about 40*F. But they need to have really good drainage - cold & wet will do them in. I overwintered all succulents in about 48*F for 2 winters, and none of them died of cold - def not jades :)

Many of these tender succulents can tolerate freezing temperatures. I don't recommend leaving them out in temperatures that cold, but all of my succulents have experienced temperatures around freezing with no damage, however the temperature jumped rapidly in the morning so they weren't exposed to too much cold. This was actually a couple of weeks ago.

45-50 is warm enough for them to be outdoors.
