Adenium Obessum Seedling Grafts

As I have around 300 adenium obessum seedlings and about 100 various arabicum seedlings from last autumn, I'm using some of them to play around with grafting experiments. I selected a few seedlings to try to start making groups of 2's and 3's of like kinds. If they survive to bloom, I can then determine which flowering tips I want to keep and graft around or mix, etc. Or use the root stocks for other grafts later.

At any rate, this is practicing with the slicing and super gluing method. Seedlings were washed, dipped in 70 % alcohol, dried, then grafted and glued a few days ago. Here I pulled these two back out of their little pots to check for signs of rot, and to photograph them. Tap roots were also trimmed though likely some of these will have the lower root sections cut off and restarted for root training later.

So far so good. If after a week or two longer these continue to look good, I'll work on additional batches with variations. And some with deeper cuts, or thick side branches.

    Also trying some side branch grafting. Will have to wait and see if any of it is successful but did a handful of them and will see.

    And one here that I added two side branches to, tips from other plants.

    I did a few of each so if some fail, others may not and I'll try more later.

    Wow, good luck with the experiment.

    My Thi Soco Golden Bell seeds take ages to sprout. Must be slow growers.

    I don't have Golden Bell but I do have Golden Crown and the seeds germinated slower than usual for me. Took more than a week instead of 2 days like most of my others. But I had very low germination so I don't think that batch was very good. Now they are going, that and the Diamon Crown are growing as fast as any of my other arabicums, so far.

    According to adeniumseeds.com, SI or Golden Bell should in fact be a fast grower. http://www.adeniumseeds.com/thai-socotranum-golden-bell/

    But that Thai Socotranum KHZ ( Khao Hin Zon) http://www.adeniumseeds.com/thai-socotranum-khao-hin-zon/ is reputed to be a very slow grower and Thai Socotranum PBN (Phet Ban Na) http://www.adeniumseeds.com/thai-socotranum-phet-ban-na/ is also slow growing.

    I find it to be an interesting website not just for ordering seed but because it gives a little more detailed information between these various kinds. I would love to find or build a database list of each of the varieties with their subtle differences written out, accompanied with good photo samples. I have been as yet unable to find such a site.

    Btw, leaves were then removed from the grafted bud tips to reduce moisture loss, and the tiny limb grafts coated. One of them is more tender than I'd like so it may not make it, the others were chosen for firmness. All of the small plants were then bagged for humidity. I even dropped in a small damp piece of sponge for the limb grafted ones to up humidity slightly as I noticed some slightly drying out even with the other precautions. We'll see how they do. All of the non side-branch grafts are doing great the past few days.

    These were sliced and then glued together? Or just glued together? I'd love to see the results! i would think the glue will form a layer of synthetic material that would block cellular growth on that surface. But maybe it dissolves eventually? Or the plant will just meld where they are pressed together and there is a gap in the glue layer? The mechanics doesn't make sense to me.

    That side-branch graft is brilliant! I wonder what it would take to sort of plant a seedling into an adult plant. Imagine if that implant develops a caudex! Hm...that sounds possible. I'm going to inventory my adeniums now. Hehe.

    You should build and write up that information on the subtle differences, Hyn. I toyed with the idea but I don't have the patience and I've since been distracted by other plants.

    You flatter me, Pagan. I need to wait and see if any of these take and come along well before I'll put too much time into them. The super glue idea has long been used with cacti with great result so that is why I wanted to try it.

    Each seedling was sliced deeply enough to nick the layers of white core subtly and then pressed firmly together before the super glue was added around the edges. It acts as a wound sealer as well as glue. As the plants continue to grow, it is brittle enough it simply begins to crack and peel off without harm nor hinderance. The only problem is if the graft slips, super glue can get in between the cuts and act as a barrier. The natural thick excretion of the cut pieces also acts to help keep the super glue from seeping into the cuts but hold firmly and don't slip! Or, try it with super glue gel instead of liquid.

    One of the seedling side branch grafts is in fact a whole other tiny seedling. But it is also the most tender and least likely to survive, so we'll see. The others are all firmer tips off of other seedlings. I am happy to write up my results, even if they fail. I often learn as much from failures as successes. So far some of the branch grafts look iffy and lost some moisture, but all of the sliced trunks are doing great so far so I have been working on a few more of those.

    Update so far though there isn't much to see, here goes:

    Most of the small side limb grafts didn't take. I feel this is entirely my fault though because I opened the baggies to air out excess condensation and left the dome lid off, then forgot about them until the next day! Those tiny grafts mostly wilted but they had been doing great most of the first week. If I hadn't had to run out the door in a hurry I might not have forgotten them.

    The grafts shown in another thread done to the tips of my seedings, have been a great success so far! Looks like about 17 of 20 have taken, but it's a -little- early to be sure so I'll wait and see if they bud and start growing. I removed the plastic wrap yesterday to examine each one.

    Of the sliced seedlings I bound in doubles and trios at the top of this thread, so far ALL of those are doing great and most of them are putting out new leaves. So I'm pretty happy but I'll have to try more of all three techniques to see what my long term averages come out to be, and get more photos later when they've grown in a few months.

    Any updates as this is so amazing ..thanks for sharing as you have beautiful adeniums and lots of knowledge and skills that I'm happy your sharing

  • 8 years ago

    Thank you. I probably won't update with more photos until next year. My sister just passed away and we moved out of our house to sell it. All of my things are in storage, and my adeniums are going dormant so they are shedding leaves and soon to be moved. I am really busy and honestly don't have time to do much with my plants right now. But they are doing well and if I can get them through the winter, I look forward to seeing how they do next year.

  • 8 years ago

    Hyn, I am so sorry to hear about your sister. I will pray for you and your family.

  • 8 years ago

    I also am so sorry for your loss:( and thank you for responding...will be sending prayers your way and am glad everything is going good with your plant babies

    I did happen to find a photo of one of them I took last month or so. Not one of the better examples. I had chosen two that were very green in the caudex but you can see now that the one on the right has taken a very subtle tint so it'll probably bloom pink, and the one on the left will probably be white.

    Some of the others have fused better and higher, but I am thinking that the end result from spicing would be more effective if done with larger, more mature plants so that they could be cut and fused higher up. The tiny seedlings have also, in some cases, pulled apart when they fattened, reopening where I had tried to fuse them.
