The leaf thet fell off yesterday:

And its underside:

And the whole plant, on which I just noticed same spots... on every leaf. That's probably it for my Lisa...

the soil looks really dry.

I agree. Letting them dry out too much kills the roots. I would also downsize on the pot.

I just watered her last Saturday. That's the pot & soil she came in, I didn't repot her since I thought I shouldn't do that at that time of the year. Right now I'd probably knock off last of her leaves trying to repot her...

Would it maybe help to put her in glass of water like a cutting?

No, you need to get it out of that mix, it's that soil that's the problem.

Is that soil hard to the touch?

All the leaves have a yellow tinge to them. Have any more fallen? Its a small cutting, if they all fall off, im sorry to say that its a gonner. A bare stem doesn't always make it. Ive lost many like that but always had a mother plant to replace them....my tip is to never let soil dry completely. (But make sure its a well draining mix.)The roots die and then you have start all over with cuttings. Sadly your plant is too small for cuttings....other reasons hoyas lose leaves (under my care) is if they were exposed to sudden cold temps or got rained on a lot. And again, dried out roots.... I have a lisa with A LOT more green that is very easy and fast growing. I bought it from yellowgree2u on ebay. He is also on fb. He has very reasonable prices...this a cutting i took from mine because this one can revert back to normal green and it was doing so. Hopefully she grows more variegated leaves.

This other one is my pretty "Lisa" she came from beastlyflowers. It took a long time to get her this size and she is still small. I would totally send you a cutting if it was larger...Mine is in a same size pot as yours but it has a large root system. I moved a little soil and i can see roots. I never let it dry out completely but also never sits in water.
see the roots a little lower and to the right of my finger?i lost part of it, which is why she is at the edge of the pot :-/

I’ve been told all the Australis varieties prefer their mix on the dry side. Maybe watering and misting may be too much? I don’t know....I keep mine on the dry side and in bright light with good ventilation and they’re growing great%

I guess it depends on everyone's zone and where they grow their plants. Inside or out. I could never go a week without watering.

Nope. Soil is loose, I'm able to stick my whole finger into it. It's pretty fine, so as I water, the water tends to stay on top for few seconds... eh, I should had repotted them after I bought them...

No more leaves fallen off as of now, but those brown spots on them get bigger. Could this be caused by spraying with water (since you said yours loose leaves after being rained on...)? I do spray them from time to time, maybe too often; with the heating on, my room is terribly dry. Mathilde started loosing tips of her vines, so I thought it was caused by low humidity and started spraying them all. Maybe I went overboard? Or maybe it was that shower after spraying with alcohol mix?

Hah, I'd love to buy backup plant from recommended grower(and I'd love to get a cutting of yours if it was big enough :)) but I live in Poland. So even if the plant would not die traveling to me, the shipping fee would me much higher than the cost of Lisa over here. Though, it's pretty hard to buy any Hoya that is not carnosa...

Your Lisa is great, btw. Mine didn't grow even single, tiniest leaf bud in the two months I have her.

But what should I do with my sick Lisa? Won't repotting at this point shock her (adding to her poor state) and kill her immediately? Either way, I only have normal potting soil, aquarium gravel, and a bit of cacti soil amended with gravel. I can't buy any new since I work in an hours making that impossible... so. Leave her alone? Glass of water? Cacti soil? Cut above the ground and try to reroot?

Isn't there a Poland seller that even people from the States had been ordering Lisa from? I saw pics on here and they were pretty good size plants....i dont know what to tell you other than, if it was mine, i would down size the pot, mix the soil its in with perlite or whatever you have handy to make sure its a well draining soil. Provide bright light and good ventilation like Monica recommended. If its dying, its going either way :-/ sorry if that sounded bad lol I'm saying it lovingly :-)

Ive never used alcohol so dont know how hoyas react to it first hand. Could have burned the leaves since you say a couple others also had the same symptoms.

I purchased my Lisa from the vendor in Poland. I purchased them as twins but they got so large I separated them and now have 2about the same size. I think Lisa is one of my favorites.

Oh, really? What is that seller called? If my Lisa dies I'll look them up.

Spraying with alcohol mix is not an uncommon practice, I read about it in many places, regarding different plants, both succulents and hoyas. It wasn't even a strong mix, nor they were left with it, I washed it off after an hour... but gollum jade really hated it. Variegated carnosa lost one leaf, but it was completely white, and pretty young, probably weaker than other leaves. Maybe it's beacuse Lisa has much thinner leaves and so much variegation...

By the way, she seems to be loosing her variegation right now. Her most bottom leaf is almost completely green already, and other are darker too...

I'm going to repot her tonight. I already moved her to sunnier spot on windowsill, watered her and gave her weak fertilizer.

If she turns completely green but lives I'll be happy too.

Do you, by chance, have a window in your bathroom? Mine that are in my bathroom are all thriving. They love the humidity from the shower. I also have a big east facing window. Just a thought. I don't pitch a plant until it is leafless. Giving up on a plant is painful for me.

Sadly, our bathroom is windowless. Windows in my room are probably the best I can get, east-south facing,2nd floor, so there's more light than on the first...

Lisa lost two leaves during repot. The three that stayed are hanging sadly, looking wilted. I'm not ditching her until she turns into bare stick, but to tell the truth, I think that's not too far off. She looks dead, all limp and darkish.

I hate that too :/ it was painful even when one of my small cacti rotted, I still had hard time throwing it away, although it was clearly dead, looking as if it was melting...

I came to that conclusion as well, since it was doing pretty fine with my watering schedule and that soil prior to spraying with alcohol. The problems started after that, so... heh, that's good to know for the future.

Lisa, sadly, seems dead. Her leaves are completely wilted. Ill try to do as you suggested, Mike, but I don't think at this point anything short of a miracle will revive her.

By the way, spraying with alcohol didn't kill the damn mealies. They're still on my Gollum Jade, and the Jade too hates alcohol with passion - it didn't die, but it lost almost all of its leaves. I read about soap solution, would that be gentler on the plant? Anything else that doesn't kill plants? Mathilde also is not happy with the alcohol.

Hi everyone! I'm Lynda from Michigan. A certified Hoya nut for ahem 'several' years. Started this obsession in my 20's and I'm 65 now. I've come to the conclusion there's no end in sight lol! Over the last year I lost several of my plants when I moved in with my Dad to take care of him. Since I've been home they've been my comfort since he passed. I've learned so much in the last few months about life and consequently, about Hoyas too. Now I'm looking to rebuild my collection and make new friends!

I'm a Michigander too! Whereabouts are you? I survive the Michigan winters in my basement greenhouse. LOL!

Hi!!! We’re in Swartz Creek, just outside of Flint. I don’t have a basement greenhouse but give me time!! Lol! I’ve finally persuaded my hubby to put up with some grow lights and I’m thrilled to see the poor guys actually GROW! It’s not a lot but I’m so happy! Where are you?

I'm in Portage, near Kalamazoo. My basement greenhouse was a $17.00 end of season steal from Big Lots a few years ago. It is cheap but does the job. I'm not sure how long it would have survived outside, but the lights keep it warm and humid enough to keep my plants happy inside. I rotate them in and out as needed. I can be found tinkering in it most days. I tell myself husband that it is cheaper than a therapist. The added bonus is that I always have a place to go that is sunny and warm!

Sounds just wonderful! I totally feel the same! Don't think I've ever enjoyed them more! AND am dying to buy more! I'm so happy to find this group and the ones on Facebook!

I have a 'Lisa" that lost her variegation. This discussion makes me want to order a new one!
