The stems can be chopped down and re rooted and the individual beans can be poked in and will also root. Make sure if you chop the stem it has no rotted portion on it, it needs to be green all through. I chop mine down each year to gain another pot full........

However, your mix looks a bit too chunky to me, I don't think the beans would root easil onto it. I tend to use horticultural grit, perlite and an already gritty compost for my Jelly beans and in equal parts. Best if all the ingredients are more or less the same size as each other., you appear to have a wide range of sizes pieces. Your plant is also stretching for the light, it needs a sunnier spot so it can grow tighter leaves. How has it got the rot, have you watered it too often?

I just got it not too long ago. It was a gift from a friend. I hadn't watered it at all. So I suppose they did too much! It's sad, because I love jellies! I'll put it into my usual mix after I chop it :)
