Small Hoya leaves slowly turning yellow
Comments (11)I used to believe that it took carnosa that long to bloom, but after Pepeuve's posts, I'm now a believer that in ideal conditions, carnosa can and will bloom quite quickly. You can see in the link below a cutting he took of a carnosa that formed 5 peduncles in under a year. I'm not sure how much longer it will take the cutting to bloom, but it's certainly doubtful it will need a decade. If you ask his advice, he says: sun, sun, and more sun. And if you go to his blog, you can see from his photos that his Hoyas, grown on a balcony in Malaga, Spain, have very very pale leaves. My carnosa is over 10 years old, however I grew it in dim light for most of that decade, because I didn't know any better. After I put it right up the glass in an eastern exposure, it formed peduncles within a year. I find it hard to believe that after 2-3 weeks in summer, your plant hasn't had sufficient time to dry out. (In fact, that sounds closer to a case of underwatering and underfertilizing). It is a good sign that you are seeing healthy roots at the bottom. If you're still seeing a decline, this is what I'd do. First, take it out of the pot and look at its roots. They should all look creamy/tan and firm. You want to be confirming that none of them look brown/black and shriveled. You also want to keep your eyes out for fungus or insects. If they look okay, then repot it with some extra perlite and/or bark like Kukka suggests, and try and step up the watering schedule a bit. The next time you're ready to water, stick a chopstick or kabob stake all the way to the bottom of the soil. This is just to confirm that the bottom of the pot isn't somehow staying damp through some miracle. It is a little weird that this pot is draining more slowly than the big one. Normally I wouldn't go through this rigamarole, but it's clear something is wrong and we have to start eliminating possibilities.

Comments (8)I will chime in. The spots appear to be fungal or bacterial in nature. This can actually be due to rot OR occur on it's own. If you do not (or cannot) return it to the vendor, please try these methods for management of the issue(s): 1. Check roots for rot. Normal roots will be yellow, white, tan or green. They will be full and firm, and have no odor, other than "dirt". Rotted roots will be stringy, mottled, can have black or brown areas, and there will be a funky smell. If the roots are rotted, you will need to restart the plant. Cut to the nearest HEALTHY node. Repot in well-draining media, like 50/50 perlite/orchid bark. 2. Remove all leaves with spots. Take a cutting or two of the healthiest areas of the plant, as backups, in case of failure. 3. To treat for fungal: I use cinnamon paste AND cinnamon mist. To make the paste, I use regular ground cinnamon, and add water until it is just damp. To make the mist, I use 3 sticks of cinnamon in a mason jar of water. Let it sit overnight (or longer). Put in spritzer or mister. While waiting for the cinnamon mist to "develop", use the paste on EVERY part of the mature plant, as well as the cuttings, stems and all. Once the cinnamon mist has developed, rinse the cinnamon paste completely off of the plant and cuttings. On the plant, mist all of it with the cinnamon mist, but be careful not to spray the potting media directly, if it still has roots. A bit of spray dripping onto the media is ok, but you don't want to drench it. If it does not have roots, it is fine to spray the media. Also, be sure to spray the root stem (the stem that roots will eventually grow from). Same with your backup cuttings. Let the cinnamon mist dry completely before returning to supplimental light/sunlight. In 3 days, rinse plant completely. I find this treatment works spectacularly or fungal infections. I also have noticed with fungal infections, after you treat with cinnamon, some spots' outer edges will yellow and the leaf will eventually fall off. Other spots will just dry out, leaving an indentation or hole. I have not had a plant with a fungal infection NOT recover, but they may look quite ugly with leaf loss and holes. I usually just restart the plant, after it recovers. 4. Since you don't know if what you have is fungal or bacterial, go ahead and use an antibacterial agent on your plant. It won't hurt it. If it is a topical antibiotic, be sure you have rinsed the cinnamon mist off completely, first. If it is a systemic drench, you can treat simultaneously. You cannot use a systemic on cuttings, though. No roots to uptake. Usually, I just dilute the systemic and spray directly on cuttings. I use Serenade for bacterial infections. Usually, with bacterial infections, the leaves will stay on, but the spots will remain indented or turn into holes....See MoreHoya kerrii leaves turning brown
Comments (8)Ugh, this kerrii is the most difficult one i think. Ive lost a few to rot before. Right now i have a couple that are doing really good. One of them is in a terracotta pot and the other, i made sure she was in well draining potting media. I have them both outside in a semi sunny location and very breezy. Air circulation is a must for this one....See MoreHelp!!Hoya compacta turning yellow and wrinkly
Comments (9)Over watered? It looks underwatered, to me. Being in that clay pot with that dry mix, my best guess is that it dries out way too fast and doesn't hold on to too much moisture whenever you do water it. I have mine growing outside, hanging from my roof, where it gets plenty of bright indirect sunlight all day long, and I spray it down every evening when the sun sets. Not only is it growing like a weed, but it's currently blooming, too....See Moregreedygh0st
