Any Hoya experts here?

last modified: 8 years ago

Hi, I recently purchased A small Hoya carnosa 3 weeks ago & the Seller graciously sent me a rather large one instead. I ended up changing out the soil (fear of gnats) and used the same nursery pot it arrived in (5”). It seems to be doing well and I just fertilized it with foliage pro this week. I’m really new to hoyas and have some questions if anyone would be so kind-

1. i noticed this week one stem end is dark with a pinky shade next to it. Is this normal? is it over fertilized? I don’t know if it happened before or after I fertilized it - but it did just happen recently.

2. The plant is almost spilling out of the 5” pot. Is this ok or should I move it to a larger planter even though I just changed out the soil a couple weeks ago?

3. What are those roots on the stems? Is that where leaves will grow? Or do they stay empty?

4. If I cut to propagate- all the discussions say to cut a 4-6” part with several leaves...can I cut any of the vines? Most have such a long empty stem I would need to cut up higher to geT leaves...

Attaching a few pictures, of the pink stem and a long one to show the size. (Its dark though).

Thank you so much!!!



Also- I posted this on both houseplant and Hoya board - should i Only post on one?

    Hi Tesla,

    Well the cat seems uncertain, I am less so.

    I'm also a regular at Hoya forum, so I'll let them answer there. Preferable to post only once, but Houzz is going thru changes as we speak which seems to allow if you post it here, it'll also post it there, recognizing it as a Hoya inquiry. So as they say, you're good.

    If I don't see responses there, or should need to, I'll comeback here.

    I'm pretty sure it's the same thread in both forums, right? That's how I thought it went. Yeah, I came here from Hoyas and you came from HP.

    Hi there! I didn’t even realize it just copied the same thread into both. Let me see if I can delete it from the housePlant forum then...

    You needn't worry abt that, it's fine, really.

    I dont think it matters. Some forums get more activity than others.

    OK then I'll start us off

    1. I'd ignore the pink, it's healthy, just new growth sometimes changes in color, mine is lighter green. Doubt it's overfertilized, but you did just repot, what kind of mix did you use?

    2. No need to worry potting larger now; it's got time & Hoyas don't mind that.

    3. Aerial roots which help Hoyas take hold & climb up, since they're said to grow like that in the wild.

    4. I'd say learn to grow the plant first, then worry abt propagating. But broadly, they need at least 2 pairs of leaves to be safest. No bare vines, they will l not reproduce w/out leaves.

    Hi Karen, thanks for the answers!

    I potted in a mix of Black Gold All Purpose Organic Potting Soil, a little more perlite and a little orchid bark mix. I copied the ingredients below for you- is this a mix that you would recommend?

    The black gold says it’s a combo of: Canadian Sphagnum Peat Moss, Composted or Aged Bark, Compost, Earthworm Castings, RESiLIENCE®, Horticultural Grade Perlite, Pumice, or Cinders, Organic Grade Fertilizer

    The better gro orchid bark mix says its a combo of: Dynamic combination of western fir bark, hardwood charcoal and sponge rock specifically formulated by a team of highly trained orchid growers

    I’m glad the pink is most likely nothing! I googled so long and nothing came up. I was looking at propagating in Case things went south, but Since it looks healthy I can definitely hold off.

    The Aerial roots make sense then! There are so many, and it’s hard to see them on others’ pictures so I wasn’t sure it was normal

    For general care I’ve read so many websites about Hoyas... So I’ve been watering around every 1.5 weeks when the soil feels dry and the pot feels light. It’s in a south window with cellular shades but hanging so high it’s not in direct sun yet. And I’ve sprayed it twice so far with diluted neem oil so it doesn’t get bugs. I’m in north NJ (I see you’re in ny- hope you’re ready for the nor’easter as well!) so when the spring and summer seasons come do you water your Hoya more often? Or do you still let it dry out fully between?

    Oh and the cat was not amused it was his feeding time and I was taking pictures of the plant

    thank you!!

    To add to Karen's response, Hoya Carnosa likes to be root bound. I hope your pot has a hole in the bottom; I can't tell by the picture. You don't want the roots getting root rot. They like fast draining soil.

    Yes! The Hoya is in a nursery pot inside the hanging planter. A bit of a pain to take out every watering time but it works ;)


    thanks everyone!

    Hi! I have been noticing a few leaves at the base of the plant have developed black edges. I’m guessing this is overwatering but I am only watering every 2 weeks Or so. The soil is completely dry by then. . Is this common on older Hoya leaves or do I have something to be concerned about? It’s pretty large on 2 of the leaves. And just edges on the others. It seems to be getting larger very slowly. Attaching some pictures! Thank you!


    edit- just a note I’m in the east coast United States zone 7 I believe. which has been cold lately.
