I know nothing about Montreal, but all of my jade plants stay outdoors all year, and so I think they would be happy to get fresh air. They grow into large bushes here, almost like trees, if they are given the space. I grow them in full sun. I have several different kinds, and some of them I have kept in planters. They seem to grow somewhat slowly, compared to other succulents, and so it takes quite a while for them to grow into a large bush.

Agree with Lars about some jade types growing bit slower. I have about 5-6 (probably more?) different jades, and the green one grows fastest IME. All are in pots because we have cold, snowy winter - I am abt. 100km north of Toronto. I did have one Crassula ovata (green-leaved) jade that was abt. 4.5' tall and approx. same in width, always in the pot. But I have seen photos of much bigger trees - when grown in ground. They can get big in pots too, but it will probably take much longer time (50 yrs+ ???)

Ok great! So when the temperature is right just put them outside in direct sunlight ? Should it be done slowly or they will be fine if exposed right away ? If not can someone detail how it should be done ?
Thx

They should be acclimatized to outdoors sun, as all plants should be. I use a shortcut: I try to get them all out early (sun is not as strong), and I try to do it when forecast calls for few cloudy days. Sometimes it works, sometimes there are only sunny days...but I have been lucky for most of the years...I have too many plants to keep shuffling them around - if it could be avoided :) If it is too sunny, I still put them in what will be their final location for the summer, but I'll put a taller perennial plant in a pot in front so it creates some shade, and move it away eventually. Or I use a chair...or a garden umbrella...anything that works, until they are acclimatized. Otherwise they could burn.

Just thought of something? What happens when it rains and your plants are outside ? Do you have to make sure to keep them away from rain? If not wouldn’t they get overwatered very quickly and Die?

They get watered mostly if and when it rains...I do not 'protect' them at all; rain is welcomed around here :) All of my succulents are outside Spring to Fall, and get the same 'treatment'. As long as fast draining potting mix is used, and all containers have drainage hole, they are OK. I also collect rain water in large barrels to be used for watering when it doesn't rain.

I had reported my jades last September 2020 with a mix of succulent soil and perlite as this forum had suggested (50/50). The soil is currently fairly hard, I assume due to watering only every 2 weeks or so and dry winter weather. Should I be repotting again prior to putting them outside when weather permits ? When I water , i do see the soils suck it in ..

The soil shouldn't be really hard, unless there was lots of dust in perlite.. Is it possible that soil had too much peat and became hydrophobic prior to less watering? Or it may have fine sand in it? Jades don't really need yearly repotting, I have some in the same pot for years. I had a plant that had very hard soil - there was sand in it, and it was in the same pot for 5-6 yrs (?)

No sand but the perlite I bought did seem to have quite a bit of “white dust”
So no repotting? Just leave it as is? Thx
