I found a four foot tall jade tree completely destroyed sitting in a broken pot on the side of the road in my town in the summer. The trunk was snapped in five places branches broken off I took the main plant home and gave it away to someone that knows more about them but i kept 6 petals that had fallen off to root for myself. All of them rooted no issue each one has their own stem with petals growing from it except.. one.. it's rooted into the soil it gets the same water and sunlight as the rest but there isn't a single shoot growing from it at all why? What do I do about it

Welcome to the Garden Forum!
I'll assume that you are sprouting jade leaves, not flower petals?
You've done very well if five out of six are growing!
Once in awhile they will fail, it's hard to say why.
It may have been smaller/weaker/older than the others, more dehydrated, or just not happy for some other reason.
If the sixth one is still green, I'd just leave it and see if it eventually sprouts. It may be busy growing roots, and waiting for longer days/warmer weather to send up a stem.
I'd just leave them all alone until Spring. You've really done well to sprout five leaf cuttings from an abandoned plant .

"..... it's rooted into the soil it gets the same water and sunlight as the rest but there isn't a single shoot growing from it at all why?" Let me preface my post by saying stem (meriSTEMatic) cells are capable of differentiating/dividing to form any plant organ tissue. When your propagule (cutting) includes a part of a stem or branch from the start, it already has meristematic tissues at every node and at the branch apex (apical meristem) where primary growth takes place. When you start a leaf cutting which has no meristematic tissues, the only way it can grow a stem is if the species of plant you're propagating is capable of dedifferentiation followed by redifferentation to form meristematic tissue. Most plants are incapable of this process, making it imperative that you include at least one node to ensure success. Many plants incapable of dedifferentiation and redifferention without a node are perfectly capable of growing roots from leaf stems, but incapable of forming a stem. These are most often referred to as 'blind cuttings'. Schefflera is such a plant.

As you know, your plant is capable of forming a stem from a leaf cutting, but there are several factors that affect the rate at which this can occur. How much stored energy the parent plant has at the time the cutting is taken is a big factor, and several other factors come into play insofar as how they affect stored energy. A cutting that came from the sunny side or top of the plant will nearly always have more stored energy than one taken from low on the plant where it is shaded by overhanging branches. Leaves or cuttings from branches oriented vertically as opposed to horizontally will also have more stored energy, and it takes energy to drive the process.

It doesn't sound like the propagule you asked about was a 'failure', so just be patient. You know the jade leaf propagule is capable of forming another complete plant, it's just not occurring at the same rate it occurred in the other propagules.

Yes I did mean the leaf lol sorry I was typing this all up before I headed off to work and didn't quite check anything I'm glad you understood. Thank you for the quick responses. I've given away a few and I still have three left I will most definitely leave it and wait and see. It has some definite roots and has rooted itself firmly into the soil. I've posted a picture of the ones that have started stemming I'm glad it's going well I wasn't sure what to expect

It's common for some jade plant cuttings to develop slower than others. If the non-shooting cutting is healthy and firm, it might just be focusing on root growth first. Ensure it's not overwatered and has enough indirect sunlight. A bit of patience is key, as sometimes these cuttings take time to show visible growth. If it looks unhealthy after a while, it might not be viable, but if it's still firm and intact, there's a good chance it'll eventually start growing.
