I have a three-leaf, four-node cutting of Hoya Caudata 'Sumatra' that I hope to root. Yesterday evening when I got it, I popped one end in rooting hormone, then planted it in a nursery pot of moist soil inside a plastic bag. It's with H. Fungii and H. Carnosa Krimson Queen.
Should I
1) store the plastic bag in light or darkness?
2) root the cutting in Leca or pumice instead of a potting mix?
3) do something else?
Regards,
Lisa
