Repot them probably, but before you do take a picture of the depotting (plants, roots and soil) and we'll be able to give you a better answer. Aerial roots sometimes mean they're not happy, it's true.

Got a shot of the soil condition? Gritty mix should be fine for winter.

I'd say under watering. Here is one of my Crassula ovatas that I've stretched watering period by a day or two, too many times:

If they do, then your problem is probably not enough water. If not, then it's probably a root issue.

Yeah there doesn't seem to be a change after watering, I've been looking for that. When I potted them all of their roots were pretty terrible, I was hoping the gritty mix would help that situation out. If I've been watering around once a week should I try watering more like every three days?

Could try watering a bit more frequently for a week or two? Hopefully will see some improvement.

If it's a clay pot, you can touch the side for a better idea of moisture or if it's plastic, try squishing the pot on the sides a little to check.

It depends so much on your exactly conditions! Temperature/light/airflow. I'm watering my plants under lights in gritty every 4 or 5 days. For the ones under natural light only, maybe weekly? Depends on species.

Hmmmm okay I'll try watering more before I go with repotting. That was my thought but I was nervous about over watering. They're currently under a grow lamp but not a very strong one. I have a pretty crappy set up for the winter... we'll see how it goes...

Agreed. Repotting would easily be 3+ weeks of your plant in recovery, so if it's much simpler than that it's a better option.

Ewwmayo, or Kevin, I think it is...(I am not one for screen names) I don't think the issue with your Jade is under watering. I do not water mine often, but do not see this condition. BTW, I do not use gritty mix for most of my Jades.

But it does look like your plant is quite etiolated.

Thanks Christopher! Yes, I am Kevin. =)

It is etoliated from long ago - the cutting came from my mother in law's Jade. Probably 20 year old plant that kept in not so optimal light (at her place of business).

Since I took the cutting this summer, it's been kept outside and inside under a fairly bright grow light until last week. That's what helped spur the additional growth at the previously empty segments.

If it's not under watering, what do you think is the cause of so many aerial roots?

Kevin

Hopefully Christopher has an idea...I just wanted to say that I think it is the humidity that causes more aerial roots - I don't know that for a fact, but many of my plants had more of them while in more humid place.

Rina

Hope so too. Humidity in my loft is 45-52% over the past 24 hours. I believe it's pretty consistent in that range throughout the year.

I think both lack of water under the soil line and humidity can probably cause aerial roots on jade and many other plants. I've definitely seen it happen to jade when there are problems down below soil level (cutting that isn't rooting, and maybe rotting) and also where there was a rotted node somewhere in the middle of an otherwise healthy plant.

I haven't seen any due to humidity, but that's probably because I'm not in a place like south florida - I can believe it could happen though.

Honestly I have no idea what the humidity in my apartment is but I watered last Saturday, again on Wednesday, and I plan on watering again today and some of my other plants are looking wayyyy better so I'm glad it was just an under watering issue for them. These three are persistently not looking so good though.
