I don’t have a bunch of Jade, but there are other succulents that grow aerial roots like Aeonium. Some say it’s from the plant wanting more water from their surrounding environment.

They do it for stability also.

I’m sure there are other reasons, but those are the two I can think of. I personally don’t think it’s much to worry about.

Is your Jade a cutting or has roots?

Aerial/adventitious roots are quite common on many succulents. As Kara said, some plants grow them to anchor plants, like Aeoniums which have otherwise quite shallow root system. Those are much sturdier roots - they get much hardier/woody with time. Some plants grow air roots that are thin and wiry - see Adromischus cristaus for example. Kara also mentioned that some plants may grow them if they want some more moisture, and I also believe some grow them if there is more humidity around (but not absolute sure). Those plants usually do not grow air roots, and the roots are short, softer to begin with but eventually dry up. I usually leave them alone.

So reasons could be just a normal development - for example strawberries; or a response to stress conditions, such as flooding, nutrient deficiency, and wounding and some more.

Other plants grow them too, not only succulents. Example would be Ficus tree that grows very thick and sturdy roots - see photo from net:

Do you mind if I ask what you mean by:..."which i got from the wild"... ?

wild meaning that i got from a road in California and not a houseplant

should i water the plants then?

Is that same plant as in your other post?

yes
