I have several leaves waiting to root, but have not a baby grown yet, so I cannot offer you my experience, RioSeven. I know loads of people here will be able to give you advice. It sounds to me that you are doing right so far, just giving half a teaspoonful at a time. I will watch the answers with interest.

In the meantime, maybe you can start few more leaves. How long do you say it took for ir to grow? Is it a 'regular' green jade? I have so many cutting I don't know what to do with them! Also have some of variegated one...

RioSeven, it has taken my Break Dancer leaf quite a while to grow a new plant, also. I was given a leaf last Summer. It has taken most of last Summer to develop a plantlet and then kinda sat there until the last couple of months. I think some leaves produce plantlets quicker than others in my experience. I watered mine as usual when it gets dry but my pot size is not too big. Of course, I tend to do what some may consider not good for gardening.

It may be from a regular Jade or a compact one, I kinda got mixed up because I tried to propagate about 8 leaves from both a regular Jade and a compact Jade. All the leaves rotted (I guess I watered them too much). One survived, probably because I realized that watering the leaves was a mistake and I stopped watering the one that lived.

Literally, it took 6 month to grow a tiny plant. But the conditions were not ideal. The leaf was sitting in front of a south-facing window during a very cold winter.

Oh, I was thinking about watering after plantlets develop.

I spritz it with water if it's just a leaf every couple of days or so depending on the temp. I don't water until I see new growth.

I think it is a "plantlet." I did manage to get an okay photo. Sorry it is not very good but I think you can get the idea.

It looks like you got it in the right mix with all that perlite. I have some leaves propagating now from other plants and I have a bad habit of not watering them enough and they die because I can go up to two weeks between waterings when school is overwhelming. In general, I think a little spray every 5-7 days is good. I've been remembering to do that and my little plants have been doing well. Two from my topsy turvy seem to be bouncing back. I think you are doing the right thing. Keep it up and just keep an eye on it.

I spray mine maybe once a week if I can remember. Just enough to get the top of potting mix a little wet.

I also have too many green jade cuttings than I know what to do with but I can't bring myself to throw them away. I'll probably start giving them to neighbors!
