Hoya plants and cuttings not growing

9 years ago

I have had some cuttings that I have bought but they just sit there and don't grow? Do I need to change the potting soil?? I'm not sure about using fertilizer because I'm not sure if it would help or burn the roots. Please help, any advice or tips would be appreciated. Thanks.

    Sorry Lisa,

    But you've given us no info.

    Some pix of your set up, some description of what soil you've used, what kind of Hoya cuttings if you know.

    We actually need to see or hear what you've done & what materials you've got to work with. Otherwise, it's a bit like asking us to mind read.

    Lisa, how long have they been in those pots? What zone are you in?...Maybe they are still growing a root system and or need to be watered more.

    It would help to know how long it's been since you potted up the cuttings. And Randi is right - your mix looks a little heavy. If you're using straight MG mix, it needs to be lightened up. Personally, I use 1/3 perlite and 1/3 coir, and everyone has to find their perfect mix by years of "tweaking"... We all water differently, or I should say we all sense dryness differently. Or maybe it's that we all have a different idea of what dry is. For me, when the top 1/2" of mix crumbles away from my finger, that's when I water. If any of it sticks to my finger, it's still got plenty of moisture. Lightening the mix will give you a chance to unpot and look at the roots, assuming you have roots growing (and you should if it's been more than a couple weeks...) Be very gentle because young roots are tender. Do NOT give them any sun AT ALL until they are well rooted and new growth starts. Just put them in a warm, totally shady spot, outside works well here because the heat and humidity are like a stimulant! And most of all, be patient. I've had cuttings root and now grow an iota until the next season. Usually, when you root them early in the season, you will see some new growth, but not always. Some species take the time to develop a hardy root system before they will start to grow.

    I don't know how long it's been since they were potted up since I bought them from a seller on eBay.

    Oh, then you just weren't real clear. A "cutting" is an unrooted stem off of a plant. If they're already rooted, then they're a plant. If they're small and newly rooted, then I call them "rooted cuttings." If they have at least a years growth, I call them an "established plant". So you either have gotten plants or rooted cuttings. How were they advertised? Personally, I would contact the seller and ask them how long they've been rooted. I prefer to buy cuttings because if it's a "rooted cutting" (meaning rooted this season), and they're sent to me in the mail, the shock of being mailed right after being rooted often means they will not grow for another season. Then it's just a matter of being patient. If they're at least a year old, you should see some growth before fall. How long have you had them?

    Thanks for the pix Lisa, it does help.

    Denise,

    is that even a legit name Carnosa splash? I doubt it.

    Tho' not abt Hoyas, pls note that while your Thanksgiving cactus looks like it's growing well, I can see from here that its mix has caked & become hard to the touch & likely water resistant. See how the whole rootball pulls away from the edge of the pot? That's a problem & is simply a matter of time before the TC starts to decline 'cause of it.

    I'd remove all the dry leaves, they don't serve anything except to provide haven for insects to hide & decay to set in.

    Hoyas have their own sense of time, part of getting to know them is to learn their preferred conditions, try to match them as closely as possible & then be patient.

    Hi Karen,

    I've not heard of carnosa splash, either. I received my publicalyx 'Pink Silver' as 'Splash', but it's really just an extra-splashy clone of 'Pink Silver.' I think sellers throw on an adjective when there's a clone that's a little different than the standard. I grow fungii, plain green, and I got a "sport" from a friend that has silver flecking, and for purposes of defining it as different on my database, I'm calling it Hoya fungii, silver flecked, the same as I note the difference between my old regular obovata and the flecked clone. I don't think there's any official designation for these slight variations.

    Hoyas will sit there for ages, from a few months up to a year, without throwing out new growth, but don't fret, they will send out new growth! Sometimes a foot or more at a time. They are very strange plants. Fertilize sparingly, at about 1/4 strength when you feel ready. I repot when new growth stalls or the plant becomes obviously rootbound: roots covering the top of the soil or growing from the bottom of the pot. I have my Hoyas in a mixture of potting soil, bark, and perlite and they thrive. Some vendors I have bought from have mulch in their mix and it seems to work as well. Also, make sure not to overwater, especially in the colder months. Has the fungi been fertilized or is the burn from the sun? And all the other advice you have received is top notch. I definitely agree with all of the above.

    I've had the same problem! I ordered a Hoya from Queensalnd (Australia) to my place in Sydney (Australia), and for two months it has just be dormant. Its health, I'm not overwatering, it's in a really sunny (but indirect) spot. It seriously just seems like a vampire, not growing, perfectly healthy just stagnant. Any tips on how to get it to grow? It's been two months and nothing.... It's a Hoya Carnosa tricolor btw.

    Since this conversation is two years old I would start your own thread with your current growing conditions, you may get better responses.
