How to propagate this cutting?

#Hoya
2ā€ pot without drainage

@Eric hello and welcome to the Greg family.

Propagation

The best way to propagate Hoya is to take cuttings that have two nodes. A node is a place where the leaves emerge from the stem. Either place them in a vase with water or into a jar with moist sphagnum moss. Check on them every few weeks. When you have a good root system, pot them in the same soil mix described above.

This is a mix of everything from perlite, sphagnum moss, orchid bark , horticultural charcoal and Iā€™m not sure what else. I have it in a humidity container and I was very surprised at how quickly it started growing roots. I check it every 3 to 4 days and also the mix of the soil that I have to propagate in when it gets dry use water that has been set out for about 72 hours and I put it all in the mixture and of course I take the plants out first. I also had my humidity container sitting on a heating pad made for Plants. Iā€™m not really sure what one Hoya is, but I believe the other two is a variegated Wayetii and a black margin.

Cuttings with Little Viable Stem

For cuttings that have little viable stem, I place what is left of the stem and leaves into a shallow dish of water.

As long as the entire leaf is not submerged it won't rot. I leave that cutting in the shallow dish of water until I have roots that are more than one-inch long. I had an IML 0738 H. acuta where all but one-half of an inch and two leaves had died. It took me around two months to root this tiny bit of plant, but it did root and I have successfully potted this plant. In this case I filled a small pot two-thirds full with perlite or ceramic pellets, then placed the potting soil mix on top of that, creating a small, raised mound in the middle of the pot. I planted the rooted cutting up on the mound, so that the leaves are not shoved down into the pot leading to potential breakage. This method does, however, require one to be vigilant in watering to make sure that that raised root area doesn't dry out too much.

Troublesome/Difficult Cuttings

As for troublesome cuttings, these are cuttings that, because of root-rot or trauma, have withered somewhat and leaves are showing signs of stress.

For these problems I turn, again, to good old-fashioned water.

The first thing I do is get a nice deep bowl of water and Superthrive and submerge the entire cutting in the water. I leave it this way for a couple of days, then I rinse the Superthrive infused water out of the bowl and continue to keep the cutting submerged for a few more days until I feel the leaves begin to thicken/harden up to normal.

At this time I decide what portion of the plant will continue to be submerged (including leaves), and keep that section that I wish to develop roots submerged in the water (make sure to change-out the water every couple of days). I often lose a few leaves in this process (they get waterlogged), but for the most part even the leaves that are submerged maintain a healthy look.

Eventually I get roots long enough (about one-inch) to pot up ā€“ and I take advantage of the several inches of stem that has roots, by potting the entire section of stem with roots on it into a pot (this time potting in more of a horizontal fashion, rather than vertical), which will ultimately create multiple shoots of new growth, and I once-again have a happily-growing plant.
