I found this link that may be of help to you.

Sorry, I couldn't help myself! I googled to see who had it, and you were the top hit. :D

lol

I have it...I grow this in a net pot set inside another container.I let this one dry all the way out before I water it again.I almost lost it because of root rot..kept the soil too wet.I had to take cuttings...now I have two decent plants...no blooms yet,but I think this ones has to be a few years old before blooms.

My little rooted plant looks terrible. I purchased it from Joni back in November. I sent her these pictures and she suggested I repot it and take a close look at the roots, which I did. The roots look great. Nice white color, long and no smell at all.

She thought maybe I watered it with cold water, or it got cold from a drafty window? None of those issues were the case. The soil was dry when I took the plant out of the pot (not bone dry like dust but not too damp that would cause an issue with the roots).

I don't know what is happening to this poor plant. It actually looks chlorotic to me. Anyway, I repotted it (in the same container after being washed and wiped down with IPA) I drenched it with Dyna gro KLN rooting concentrate and Foliage Pro. I guess I'll just have to keep my eyes on it. I didn't realize it's kind of a difficult variety to grow (or maybe it's just me - lol).

If the leaves look of feel leathery or dehydrated...the roots are rotted.If not maybe over fertlized?My leaves looked the same when cut it up to restart it.

Jimmy- your plant is so green and beautiful. I checked the roots and they are fine (no smell or off color). I don't think I over fertilized. Actually, I don't think I fertilized it all (only one small dose of BATS) but maybe since the plant is so small? Not sure. Should I just leave it be and see what happens? Thanks

I'm envious of yours :-)

Maybe I should try some pots like yours, they're orchid pots right?

That's weird, it does look like it got cold. Maybe it's just adjusting to it's new environment? I've had plants that arrived perfectly healthy and then a few weeks later tank out of nowhere, for no apparent reasons. I would just leave it be, and cut off the funky leaves when it shoots off new ones.

Jimmy, you have the nicest Hoyas. The End.

I would let it be and see what happens..if you loose it,i can send you a cutting of mine or root you one.BATS would have no effect on the plants...just insects nervous systems..lol. Cold be a factor,although for me it appears as brown or black splotched and limp leaves.The pots really don't matter,but i like the net pots because it's easy to see the roots and they allow more oxygen to the root ball.I buy the outer pots at the dollar store..they fit the net pots perfectly and they come in a 6 pack for a dollar!The net pots are pretty cheap as well...here is the link to the ones i like the best.Thanks for the complement Tawny! http://www.amazon.com/gp/product/B00MR17WMO?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00

Thanks Jimmy. It's so kind of you. I really appreciate it. I also lost my Hoya Limoniaca and I just got it today! It arrived with mites and fungus. :-(

Monica, the ones I received from Joni arrived looking like your plant. Despite the heat pack, and the quick ship, my $100+ order got cold and that is what cold damage looks like. Sadly, NONE of mine made it.

On your limoniaca, I don't see any mites (would need a microscope or magnifying glass to see those anyway) or sign of them. I am assuming the black spots are what you think is a fungus....it may very well be fungus, but to be honest, I have many of those same or similar looking spots on my hoyas. They never grow bigger (the spots) and just appear to be cosmetic or damage. Feel free to use an antifungal spray (I use either copper or Natria Disease Control) as a precaution.

I do think I can see a singular scale insect...easily treated with rubbing alcohol.

I have never received a diseased or buggy plant from CBFM, not saying it cannot happen, though.

Thanks aurorawa. I contacted Cowboyflowerman, Jodie and he requested the plant back. In the below photos you can see webbing and little tiny marks on the back of a leaf that looks like mites were sucking away. My husband works for Bayer CropScience so I have all the stuff to treat it but I wanted to let him know (I don't understand how the person that packed the plant didn't see it. You would think they would at least clean the leaves off)

I'll wait to hear back from Cowboyflowerman. Since this was my first order with him I was a little disappointed. The other plants look okay.

The three other Hoyas I rec'd today.

The tiny black spots on the back of the leaves is very common in the hoya species, as a whole, and does not indicate spider mites. The webbing is too big, in my opinion, to be spider mites, and in the wrong area (undersides of leaves, and unless it was a heavy infestation, you probably wouldn't even notice. I have never had spider mites, but I have had a scale or two, as well as the odd mealie.

*edited to add photos of a few of my hoyas that have black spots. Not sick, no bugs, just normal.

Thanks so much aurorawa. Jodie said the spots are not fungus but pigmentation that happens in winter. He said the webbing is probably from a harmless spider. He didn't say anything about the scale.

It's okay because I really want a Limoniaca. I removed the scale and treated with Bayer 3 in 1 (foliar & systemic). I think it will be okay, I'm just going to keep it away from my other plants for a couple weeks.

Hi all, I've stumbled across this thread whilst seeking advice on two of my favourite hoyas, which have come down with some kind of mystery ailment. They've been growing perfectly well and flowering for two or so years and now all of a sudden have both been struck by some kind of issue I can't seem to identify, wondering if it would be OK if I posted some pictures and got some advice? I'de really appreciate it!

Monica, I have limoniaca. It is smallish yet, but I just checked and there is a nice leafy 3 node chunk that would make a good cutting. Maybe you would like to make a trade? Message me if you do. Otherwise, I have heard good things about cowboyflowerman. Good luck and keep us posted, I am curious the results. I am currently bummed with a plant vendor myself, I paid for a winter shipping box (foam lined with heatpacks) and didnt get it. Arrggh.
