Clear gel forming on stems when rooting cutting in water

lsst
11 years ago

I have noticed when I root stems in water, the stems develop a clear gel on them.
I replace the water regularly and try to rinse off the gel.
Does the gel help or hinder the rooting process?
What is the gel?

The stems in question are Althea and Confederate Rose.

Thanks in advance!

    no pic.. no opinion... from me anyway ...

    how big a blob?? ...

    it probably isnt good ...

    dad tried rooting rose in water for decades.. i think he rarely had success ... he did much better 'sticking' cutting in mother earth.. and covering them with glass jars .. creating his own mini greenhouse ... but that was old school 30 years ago ... and probably the same thing with althea.. not many woody cutting root in water ...

    and that is not to say you might not get lucky.. but you might want to bone up on propagation methods.. should you wish to step to the next level ... michael dirr wrote the book ... see link

    all that said.. you have little to lose.. trying it .. good luck

    We see questions here over the years about rooting in water. I don't understand. Why root in water?

    Even the houseplants that will root and grow in the aquarium don't take well to transplanting in soil. The roses mentioned will not grow in water, will they?

    I like to experiment.

    I am constantly trying different methods to see what works best for me. I have been experimenting with plant progation for about 12 years.

    I will take the same plant and do air-layering, ground layering, cuttings in soiless medium etc. I then take my leftovers and stick them in water just for fun.
    I hate to throw anything away! LOL

    I then record my results in my gardening journal.
    I have had fairly good success with most ways of propagating.

    The scientist in me just wonders what the gel is.

    I have enjoyed this forum immensely and have learned a lot from everyone here.

    Thanks

    Lsst,

    I've seen it too. I've also been told by many gardeners who know what they're doing that certain plants are just plain easy to root in plain old water.....of course changed often.

    Could be Pseudomonas or a fungus. In the university lab we often would soak specimens briefly in undiluted bleach and then rinse.

    Thanks!

    I guess what surprises me is that even if I change the water everyday, the gel returns.

    I own a florist and I am beginning to think it may just be the "slime" that forms on the stems of cut flowers.
    In my shop, I use special additives to prevent it.

    In the past when water rooting, I have used a drop of hydrogen peroxide in the water at water changes. I recently read where too much hydrogen peroxide would inhibit rooting.
    I quit adding it because I did not know what was too much.

    Albert 135, In the future I will try the undiluted bleach. I would have thought it would have burned the stems.
    It you did it in the lab, apparently it does not.

    I have had quite a few things root in water and have successfully transplanted it to soil. I have had my failures as well. To me, it is basically an inexpensive way to try to propagate.

    Growing up I remember my grandmother always had something rooting in water on her kitchen window sill and I like to do the same thing as it brings back fond memories.

    ==>> because the pathogen is on the tip of the plant.. and not in the water..

    if it were in the water.. it would be generally dispersed.. not stuck to the end of the cutting.. dont you think ..

    and i would dip in 10% bleach.. if you want to experiment.. not 'undiluted' bleach ... and work your way up dilution if you want ... [you might want to wonder if household bleach is the same as lab bleach .. i dont know]

    keep experimenting..

    To make sure what plants you are talking about, by Althea, do you mean Hibiscus syriacus, AKA rose of Sharon? By confederate rose, I'm assuming Hibiscus mutabilis?

    Also curious if you are asking about something that happened in the past?

    If the cut end of the stems of either plant was/is too woody and old, it will have a much harder time taking root, especially in water which is much more conducive to rot during the process, and especially if it was cut recently in the cold. For H. mutabilis, I'd try to get a really fat but still green cane. For H. syriacus, I'd try a much smaller semi-woody cut.

    I would strongly urge you to try cuttings in soil next time, whether in a pot or in the ground, and to do it from mid-spring through summer. I took cuttings of H. mutabilis in June, from about 18" to about 30", that bloomed in Oct/Nov, they go really fast if the timing is right. Water is not the best method for woody plants like these, that's really a house/jungle/tropical plant thing, even if it often works. There's a much higher chance of failure, especially at a time of year when the plant in question should be dormant, not actively growing.

    The jar of water is an extra step over starting in soil to begin with, and has an unnecessary component of pessimism... if it roots, I'll find it a pot or dig it a hole... Go in there with more confidence!

    H. syriacus grows readily and quickly from seed, if you'd like to try that also.

    Thanks purple,

    The plants are Hibiscus syriacus, AKA rose of Sharon and confederate rose, Hibiscus mutabilis.

    The Althea is rooting but I have had trouble rooting Hibiscus mutabolis for three years in a row.

    I have tried every different form of soiless medium that has been recommended.I just can not get the stems to root!

    I did have one Hibiscus mutabilis seed sprout and it is a cute little seedling just having formed its first set of true leaves. I did the baggie method and transplanted it.

    What is weird is that I can get things like camellias, gardenias, azaleas and magnolias to root just fine.

    It bugs me that Hibiscus mutabilis is supposed to be so easy to root and no matter when I cut the stems or how I try to root it, roots will not form or form long enough for the plant to survive.

    I just purchased unrooted stems of Hibiscus mutabilis off the internet. The seller did not advise as to how she gets her to root- I was hoping she would.

    The new cuttings are sitting in water. The top and bottom of the stems are turning brown.

    Thanks

    What is the best medium to root Hibiscus mutabilis?
    Maybe I have not tried them all.
    Is there a special recipe someone will share?
    I am half tempted to just dig a hole in the ground, stick them in there and see what happens. LOL

    Lsst, I do cuttings in a mix of finely shredded mulch, some rough home made compost, whatever's handy that is very coarse and airy, so I can water about every-other day without worrying about making mud, causing rot. Are you trying in the spring/summer? What size pieces are you using?

    The only problem I see with putting cuttings straight in the ground is that in full sun, they'll probably fry before they take root. If you can use a chair or something to make temporary shade, that might be worth a try but could still be too much ambient heat.

    Thanks Purple,

    I was just kidding about the straight in the ground method.
    It is too cold here but that is one way I have not tried LOL.

    I am probably taking the cuttings too late in fall.
    My last cuttings were taken mid-October. The sizes are probably not big enough.

    The most recent cuttings were sent to me from California, just a few days ago. The seller states they were in a greenhouse. The cuttings are at least a pencil width thick which should be a good sign.

    I normally use a peat mixture with perlite.
    It still seems too heavy and I wonder if it is rotting the
    roots.

    I really want this last set of cuttings from California to root.

    The same thing happened to me on some of my clippings that I rooted in water. I noticed that the ones that got the most sun (jade clippings on the windowsill) got the sliminess fastest. I just rinsed it off and changed the water more often. Ive since transplanted it to soil and its doing great. But I would like to know if adding hydrogen peroxide to the water would be better than changing it every few days. What is the dilution rate for hydrogen peroxide to water?

    This persistent fascination with rooting cuttings in water is taking you away from much better procedures - if - you really want to propagate the cutting.


    A good procedure is described here: Propagating Plants by Cuttings .

    I spray cutting stems not the leafs with 10 % bleach water and rinse every 2-3 days. I also change the water every 2-3 days and wash my cups. I don't deal with slime no more. You can you use peroxide to, its probably the better route. but I'm happy with my method.

    I noticed a “gel” on my rooted pathos cuttings today when changing the water. However, when I removed the stems from the water and placed them on a paper towel, the “gel” disappeared and I was left with tiny hairs on the roots (which is apparently normal). When I put them in new water, the hairs looked like gel again.

    Is this the slime you're all talking about? I'm working on a citrus cutting from a small citrus tree. Sorry the jar is etched a bit but hopefully you can make out the wispiness coming from the sides. I also etched the stems some, as per recommendation from elsewhere to assist in rooting.

    This is what I am curious about. is this fuzziness a bad sign? I am trying to root an olive branch from Isreal.

    Woody entities are, generally, more likely to rot than root in water, IME with propagating various things.

    Root primordia is different from decomposition.
