I don't know what it is worth, but I've got a Rubbermaid box with mum cuttings. I sterilized the planting mix in the oven: sand, perlite, and bark fines.

I ran out of mix before I ran out of cuttings and 2 of the cuttings went into 100% perlite.

I haven't lost any of the cuttings yet, but the ones in 100% perlite are the ones that look by far the best.

If these little guys root, I'm not quite sure how to transplant a baby with only perlite without having the entire root ball fall apart.
