Dennis,

One of the most important things when cutting roots or branches, which you probably know. Make sure blade is clean w alcohol w each cut and most importantly that all rot is cut off. There CANNOT be any discoloration in tissue. If there is it will continue to rot, even w application of cinnamon. I prefer Sulfur powder for root cuts. Just me.

I am a bit dubious about the way that the bark and cambium layer is separating from the core. I am not sure why. Hopefully someone will chime in also.

Best to let it hang somewhere out of sunlight, in warm area for at least 5-7 days, possibly longer. Do check cut ends frequently for softness going up the root.

Rick

Thank you Rick !

I cleaned the knife after each cut properly and all the cuts where free of rot. The way that the bark and cambium layer is separating from the core is maybe i also don't know maybe because i let them dried inside my house where the temperature was constantly like 22 degrees but they dried very slowly because of that. Letting them dry outside was not a option because of the bad weather we had a lot of rain and the night temp. was also low

Next time you needn't wait 3 weeks to dry. You can soak the entire root (or the entire plant) in a fungicide or better yet, a 10% bleach solution about 10 or 15 minutes after cutting off rotted root material. Then as already mentioned, lightly dust or spray the roots with sulfur and repot with or without allowing for a drying time which by that point really isn't necessary.

As your plant will be stressed, using a sterilized potting mix you baked in the oven at 350 degrees for at least 30 minutes also wouldn't hurt in case you missed removing some damaged material (make sure it's cool before using).

I do tissue culture so I can assure you that the 10% bleach solution soak is standard treatment to sterilize plant material without harming it. It can slightly damage the cut tips as the solution is absorbed which is why I'll make fresh cuts before putting down meristems, leaves, or other cuttings but on a larger plant this really isn't a concern. Dipping your knife in 70% alcohol is a quick, easy way to keep it clean.

Good luck and I hope it's growing well for you!

Btw, do remember to rinse well after a bleach soak - ideally using distilled or other sterilized water but even tap water will do if you aren't propagating small pieces.

Thank you so much for your help ! next time i am going to do it that way. So for now i dont have to worry my cuttings even they are looking like this ? the cuttings feesl hard and the roots to.

Dennis, have you already managed to find sulfur powder to use as fungicide? I can't seem to fin it anywhere in the Netherlands :-(

Hi-yield makes a good wettable sulfur powder but if you look for things for roses you can often find powders or sprays for treating black spot and other fungal issues. I usually prefer a spray myself but I have both. I have no idea if you can find that in the Netherlands or order it. Incidentally sulfur is also pretty effective against most mite infestations.

Didn't find anything till so far of that Conny even like a nice fertiliser.

I've been using cinnamon powder so far, but somehow feel sulfur would be better. Will have to do a more thorough search.

Also nice Adeniums are rare to find here in the Netherlands only sometimes in Delfgauw by Otto or by Florastore but from the last one I don't know how the plants are

Me too using cinnamon ! And there are also no nurseries around here to get plants or knowledge about Adeniums that's why I am so happy I found this helpful forum ! My experience till now is that every Adenium I bought here didn't had the right soil for our climate

I do have a word of caution about sulfur. If you have used /anything/ oil based to spray your plants in the past month (like Neem oil) DO NOT USE sulfur. Sulfur and oil mixed causes phytotoxidity in plants and can kill your plants. As I use sulfur for a lot of things I am very careful never to use oil based treatments like Neem anymore. Or if I have, I'll wash the leaves with mild soap and water before I apply any sulfur.

Yes, Otto does awesome plants. Tomorrow I'll post a picture of our big boy we got from him last month. It's in full bloom now, so tonight we gave it a more prominent place and moved it into the living room.

From Florastore, I bought 7 adeniums. Pretty impressed with the vatiety and quality so far.

One of the easy care arabicums I got at Intratuin is about to flower too, yay.

But Dennis, you are right when you say that all adeniums we get here come in the wrong substrate.

This forum contains a wealth of information you'd never find anywhere else :-)

So Are my cuts looking dry enough to put it in soil ? And wen I can put it in soil do I give it water right away ?

Thanks Patty ! What do you mean with IMO ?

They're looking well Dennis, and very nice view too!

IMO = In My Opinion

Thanks Conny ! Hope they will doing ok ! These are the nicest caudex I have so i can't lose them

Let's see how my seedlings get on over winter and perhaps we can add a couple to your collection :-)

That would be very nice i also have a name for them Arabicum Rufus

Sorry, was out of town there. IMO means 'in my opinion' - they are looking good! Keep the watering a little on the light side and you'll have new roots growing pretty quickly I should think. If any of yours bloom later you can cross pollinate (or even self pollinate) and make yourself a lot more seeds. Especially if you want to experiment with grafting and training root and limb structures, carving trunks, etc.

Thats a nice idea Patty ! Thank you !

Here is something else I learned recently with adeniums with rot. If you have a prize plant that rots badly BUT you still have enough plant left that you can cut above the rotted portion, you /can/ graft on all new roots from another plant! I just learned this on one of my Facebook groups and was like ... wow. I should have thought of that, ha! There was step by step instructions with nice photos.

So don't limit yourself to only thinking of grafting as only adding branches and buds. You can add roots as well. If your adenium is unbalanced in it's root form? Maybe no longer a problem. I did know you could graft on roots for regular bonsai but I had forgotten that tidbit over the years.

Better of course that you caught yours early. Saved you the trouble. But the information might still be useful some day.

You can do so much with them unbelievable he , in which Facebook groups are you ?

If you wish to go find me on Facebook, look for Hyn Patty, Athens GA. Then you will be able to see all of the adenium groups (and other groups) I belong to and join any that you also like. Or you may search for groups on FB directly yourself and investigate them accordingly.

Patty is it wisely to check my roots after a couple of days/weeks to control if they are free of rot or does the plant get in a new shock because I put it out of his soil again?

Dennis: as far as I know, leave the roots alone now for a long time. Checj the firmness of the caudex and see if there's new growth on the plants, that will be the best sign (from my experience).

Do i have to send you a friend request to see the Adenium groups ? Only saw the group Rosas do deserto

How is your plant with root rot going Conny ?

I agree with Conny, don't mess with it. Water lightly and wait to see how it goes. It's not wise to stress the plant more by messing with the roots without need.

Yes, you need to put in a friend request to see all of my groups. But you may also simply search FB in the upper edge, slightly left side of the page. Put in Adenium (or whatever you are looking for) and scroll through the results you get to see what you like.

Ok thanks Conny and Patty

Hi Dennis, my rootrotten plant finished flowering and lost all of its leaves but is starting to show signs of new growth again. I haven't watered it since it's been bold.

Because of the new shape of the caudex I replanted it in a boatshape pot. I have tied the branches to try and make them grow in the same shape as the pot.

Despite all this: parts of the caudex still feel a bit soft, so will have to keep a close eye on the poor thing.
