12 or more hours of artificial light, and temps at 70 or above will speed the rooting process.

Lisa tends to rot (for me), if I attempt to root in high humidity. I have had the most luck (in the cool months - in warmer months, rooting is a breeze) rooting on a heat mat and placing the cuttings in the same media/conditions as the mother plant. They are cut, potted up, and placed under the lights.

aurorawa Check out these aerial roots that came from the humidity.

Now they are growing into the substrate.

I said, for ME, higher humidity than the air in the plant room, causes rot. Mine all grow nice, long aerial roots, too! My ambient humidity is already quite high. Your results may vary.

I was shocked to hear that you had any cutting that rotted. Especially with the mix you use.

Humidity is not always a good thing. I am, by no means perfect, lol. And this winter is especially harsh; ambient humidity is high, but temp has just not been stable. This winter is the first time in three years I have had to turn the space heaters on.

Lisa CAN be a tough one to root. It doesn't like overwatering, likes it warm, and actually does better in drier conditions, IF temp is low/unstable, and if air circulation is not at a premium. In stable temp conditions, with good airflow, it thrives in higher humidity.

Lisa is a variegated form of ssp. tenuipes, which hails from the Pascoe River region of Northern Queensland, where humidity is relatively high, temps are quite high, and oceanic airflow is high.

This winter, I have been unable to keep the temp stable enough to keep humidity where I'd like it to be, without minor issues. I consider rot to be a minor issue, especially in cuttings, as it is easy to reverse. If it is a mother plant, I take cuttings. If it is a cutting, I cut of the rotted part, and restart. A (minor) annoyance, but par for the course.

It's been really drafty down there for reasons unknown to me, until recently. I have had to keep the laundry room door shut, as the water heater/utility/gas thingie (we have natural gas for heating and cooking) are in a closet beside the small shower in there. Even with that closet door shut, there is still a severe cold draft. Can't block what is causing the draft (vent for utilities), so the laundry room door gets closed and a towel rolled up and placed in front of the door, just in case any frigid air tries to get out through the (small) gap.

The mother plant is in a 50/50 potting soil/perlite and is under T5 lighting. I had the cuttings in the same mix just not the bright light. I can try again with fresh mix, heat pad and 12 hours of light.

Would Lisa do well rooting in perlite? As well as under lights and heat?

OMG! Can someone please tell me how to get a Lisa? I only see them from Poland and both times I tried that they completely rotted before I received it. I don't know what that is about.please Tell me where I can get one?!?!?

I have one rooted for you lol! Just waiting for warmer weather.

Tony, your Lisa is gorgeous! I'm so jealous. Now I'm trying to root 4?cuttings as I must have over watered one of my plants.

Keep in mind I'm still growing 15 Citrus trees so sometimes I forget which ones I watered a week or two ago. I've learned that even if Lisa's mix looks dry it's okay to not water for another week with no ill effect. I finally learned....when in doubt to water or not always choose NOT:-)

Yes, my big lisa plant was just watered last night. It had been awhile since it was watered. The leaves were not droopy but they were soft to the touch which is a good indication they need water.

I think that small rooted "lisa" is gonna go on ebay eventually.

tlbean2004,

Please post here when you put that 'Lisa' on eBay; I'd like a chance to bid on her! :o)

I am always looking for places to purchase Hoyas; would any of you folks be willing to share your favorite online nurseries with the rest of us?

I have ordered from Green: Plant Research in HI and SQR Hoyas in FL as well as a few other places, but many of the plant nurseries that carried or specialized in Hoyas are no longer around.

Thanks!

Yes, I will put a post on here when i list it. Gardinos is also a good place to buy from. They are at rareflora.com
