Hoya Carnosa new growth yellowish

7 years ago

I started this plant with two cuttings. It’s planted in 5-1-1. It’s high up in an east window with the blinds down a bit. I fertilize once a month with dyna gro 9-3-6. The new growth was before I started fertilizing. I let is get dry before watering.

The new growth on both vines is pale green one of the leaves shown is somewhat stunted. It doesn’t have the shape of the more mature leaves. You can see it at the tip mostly.

I feel like it could be a fertilizing issue since I just started last month. Or a light issue.

    Hi, Are you new to Hoyas? Some shape & color variation isn't uncommon w/ Hoyas especially Carnosas & what I'd guess is a Kerrii also in the pot. Sorry, but the pic is too dark to see the actual plants in the soil. Is it just those 2 cuttings in how large a pot? Measure of pot's diameter pls? Is that a 6" diameter or larger? Too large a pot can contribute to overwatering-like problems.

    Likely too much fertilizer, maybe overkill, esp on what looks to be a small cutting. I'd stop that completely. May I ask how you assess when it's dry enough to water?

    I think it looks fine & don't see a problem. Handsome plant hanger, looks nice.

    I have been growing Hoya Bella for many years but I feel like that’s a Hoya anomaly. I have only fertilized this plant once and it was after these leaves were the way that they are. I thought the color was because of it being a young leaf at first. I was waiting to see new growth before I fertilized. For watering I put my finger way down into the potting mix to see if it’s mostly dry, a tiny bit damp. Also by weight of the pot. It’s in a 6” pot. Here are some better photos and showing new growth. I just watered today.

    One more of the potting mix.

    Thx for the MUCH better pix & details. I'm not a 5/1/1 user, but that mix looks good from here.

    I see now it's 2 Carnosa cuttings? Again, I don't see a problem, let's allow some time for others to chime in.

    I grow other Hoyas, didn't do well w/ Bella, but over yrs. my keepers have been: Publicalyxes, Carnosas, Kerriis, Compacta, etc..

    Were I to adjust anything on yours, I'd pot down a size, into plastic pot & put it on a pebble tray. This Forum seems rather slow, but let's give it some time.

    I agree with Karen, i have several around that size that are rooting and I have them in either 3 or 4 inch pots, depending on the cuttings

    Thanks for the feedback!

    You're most welcome, hope it helps!

    My Hoya leaves gradually get darker as they age. and firmer too. I think your plant looks very healthy, and normal.

    pot's too big for those two little branches.

  • 7 years ago

    Pot size is fine for these two vines. I started watering more often and the new growth looks great.

  • 7 years ago

    The pot is too big.

  • 7 years ago

    I too agree, the pot is too big. I have bene growing Hoya for years and as Karen said be careful about over atering. The 5.1.1 will give you a better advantage about over watering, but it is still possible to do so.

    Since watering more often resolved my issue I don’t think pot size is a problem. IMO the problem of too large of a pot = to much moisture in the root system. That wouldn’t be my issue in this case since I’m having to water more often. I would think the larger the pot you can use without overwatering would be better considering there are no pot sizes in nature. So now the root system has freedom to grow and the plant is receiving the appropriate amount of moisture and light as far as indoor conditions allow. I’m happy with my plants current growth and development. Thanks for the feedback.

    Well certainly you'll find out what the plant prefers, but comparing growing in nature vs. in containers doesn't really compare, apples & oranges. And also, that ignores Indoor vs. Outdoor. I think it's more complex & has more variables than you may realize.

    Hoping you'll share some updates w/ us periodically.

    It's funny how hard it is for me to assess the pot size for Hoya. They really do want smaller pots and it's such a departure from normal repotting. I agree that is a large pot for the plant.

    Considering how a plant grows in nature is relevant to how we grow them in containers. There is no value in comparing an apple to an apple. I more than understand the complexity of the variables at play. I have navigated them in my own way with success. My Hoya is happy and healthy with more than enough room to grow and the appropriate amount of moisture. No one has backed up their pot is too big claim other than moisture retention which wasn’t my problem. It was the opposite.

    As @Laurie (8A) said, it should darken as it ages. It’s normal for new leaves to sometimes lack the same colour as mature leaves.
