lacunosa

| I have a lacunosa that is several years old. It never grew much but has bloomed nicely in the past. For the past few months it has stopped blooming and since it got a little too dry, and now it has yellowing leaves. I repotted it recently in nice loose mix, hoping that would help. Now I have fungus gnats. In all my plants. I've done a soil drench with the Bt stuff from Gardens Alive for fungus gnats and am waiting. So far no new bugs.
My question is this - there are green leaves at the ends of some of the vines that look like this thing might have been trying to grow recently. Should I take cuttings of it now, using these green leaved vines and try to root them? I have never taken cuttings from this hoya before. Does it do better rooting in soil or water?
This plant has always drooped, and the leaves are thin and not waxy looking. It doesn't even look like a hoya to me. The blooms were wonderful, very fragrant. |

| Are the leaves dehydrated or just thin (which is how they are naturally...)? My lacunosa goes through phases where it will get yellow leaves and drop some of it's foliage. In fact, mine is doing it right now. I think it's in reaction to letting it get a little too dry, then going back to normal watering. I let my dry out a few more days than I normally do. It makes it harder for the roots to take up the water, and I think it then has to readjust. It seems like it always bounces back for me, though. Can you post a pic of your lacunosa? It might help. I have to say, though, that lacunosa is kind of hard to root (for me anyway) and can react poorly to being repotted. So you could have a few things going on there - letting it get too dry, repotting, gnats... I would probably take some cuttings just to ensure that I didn't lose it. Try starting some in a little pot of soil in a baggie, but also try putting some in a baggie of sphagnum moss - rooting ends go in the moss, then clip it closed so the growing ends are outside the baggie. Keep the sphag moist and put it in a spot where it's shady. It's my new favorite way to root Hoyas. Denise in Omaha |

| I would take cuttings too if you think you might lose the plant. I'm lazy and I root everything in water with a little charcoal and I have great success, but in this case I would recommend trying a few different rooting methods just in case! Denise, i'm totally going to try your way too now! I have a new bag of sphagnum moss that I have been looking for something to do with it! |

| Below is a link to an issue of Stemma which has a whole bunch of grower's propagation methods. You can see that rooting methods can differ tremendously. It's really about what works for you. Good luck! Gabi |

| I hope this works, it's a picture of how the plant looks now after losing about 2/3 of it's leaves. I have taken no cuttings yet. The ends look like they are greening up a bit. Sad, huh?  |

| Its been my experience that once this looks like this its to late. I think you are going to have to buy a new one and try again. Cindy |

| looks to me like there are some cuttings possible |
RE: lacunosa

| Yeah, I would take cuttings and then soak them in some warm water with a little sugar added to see if they will become turgid again. If after a few hours they don't improve, then you may want to see if you can find a new plant at Home Depot, Lowes, Walmart etc. I find that H. lacunosa does much better for me if the plant is grown in a plastic pot so there is less chance of the plant drying out too much. That being said, I think that H. lacunosa is one of THE most difficult hoyas to grow - at least for me. I do have some cuttings started that are doing OK, but now I need to pot them and we will see how it goes...
Good luck,

| I agree with what was said above. Soak the cuttings for as long as it takes, 12 hours if you have to. I also grow Hoya lacanosa in plastic pots because drying out is not something that it likes to have happen often. I don't grow any Hoyas in non glazed terracotta pots because it just means you have to water more often, once or twice a week in a plastic pot is enough for me. Mike |
RE: lacunosa

| I guess I forgot about clay pots. After reading on Stemma and here some more, I remembered! I went looking for another hoya today but only found one of a variety I don't recognize and it was pretty sad. Almost wanted to buy it to give it a good home. THEN I noticed fungus gnats. I don't need more of those! So when you say to soak a cutting, do you mean take the cut end and put it into sugar water? Should I use sugar? How much? The only other hoyas I have are a carnosa from my mother's big plant and a hindu rope from the grocery store that has taken over my window. In fact, it's in a clay pot...... |

| You will need to completely cover the cuttings with water so they can try to rehydrate their tissue. I would add maybe a tsp of sugar per half gallon of water or so. If you have a large-ish bowl or a small bucket you can fill with warm water and then add a little sugar and stir to disolve the sugar and then put the cuttings under water, completely. If the cuttings are too far gone, nothing may happen even after being soaked, but you might be surprised. I wouldn't soak the cuttings for more than about 12 hours or so. If nothing happens after soaking for about 12 hours, the cuttings were too far gone.
Good luck,

| Thank you, that is very nice of you to offer! I think that these cuttings are actually looking like they are growing, so I would like to wait and see if it takes off on it's own before I give up and replace it. The greenest of them is really perking up, there are two that look very good, the others are probably not going to take but I didn't expect them to. In fact, one has a bloom spur on it, and it looks like the thing is now trying to bloom! I'm excited. |
