Soft khaki brown area on caudex need some expert advice

10 years ago
last modified: 10 years ago

I decided to pot up my adenium after 3years when I did the trunk was firm and fat and all the white part was hard I mixed a good bit of sharp sand into the cacti mix from Miracle gro I dipped in super thrive and then repot it. I did not water for a couple days and when I did the soils drains out the buttom in literally less than 10 seconds I did not put much thought to it other than I got the drainage part down really well. But after 2 weeks I noticed one part of the trunk that was swollen is soft like a cushion but part of the caudex was originally out the soil is khaki colored and new area was begun turning green I live in trinidad it's 36 degrees outside everyday and it's now beginning to rain a bit it's been a month since I repot on the same pot.i don't know what to do I love this plant I am at a loss as to whether my soil is to fast draining or if it's rot it has not dropped a leaf only one leaf turned yellow yesterday but I have been flooding it with water thinking I was not giving it enough thanks for your input really need the advice I don't want to disturb the plant agin

    Thank you for you response was really hoping I did not have to up root it again

    Marica is right, but I'll offer a quick response; it looks like sunburn on previously buried roots to me.

    You will still need to dig it and see if there is any rot, but a quick look tells me this guy would like to be deeper, and I'd let him do it for a few more years.

    I agree you need to check all the roots and cut back rotted parts to white/cream tissue and repot a little lower like before. Sand of any kind rings alarm bells with me! MG compost can stay really wet and when mixed with sharp sand alone may not give ideal conditions despite you thinking so. Water can bypass the mix and run straight out if it's dried out well, then when you water in sufficient amounts it eventually soaks through....and it stays wet with the rain you say you're having and the floodings you've given it. The sand causes the mix to compact and drives out air, all contributing to possible root problems.

    If you're prepared to water frequently being in such a warm climate, and as this would drain fast, maybe the gritty mix most of us use would be better. It can be tweaked to suit your growing conditions but basically is 4 equal parts of seived perlite so use just the biggest particles, screened bark bark chips/, horticultural gravel/chicken grit/aquarium gravel or anything like that which is available in your area, and yes dare I say it, something 'similar' to MG. The idea is to get as much of the mix as you practically can all the same size. There are lots of recipes that you can read about by searching for gritty mix in the box above, and maybe someone else will advise you more specifically for your climate and conditions as mine are way different to yours.

    Every one explained things real well. We all think maybe the soil is soggy with the sand. When you stick your finger into the soil , is it moist or very wet? These are very hardy plants. We have had them bare for weeks sometimes while we work on it. For the first 3yrs to now what has changed. The soil? set in sun to fast after transplanting? The need part shade for the first week or so. I think you said the pot is the same. Different pots can dry out fast or slow depending on the material it's made of or the amount of drain holes.

    Sunburn can cause the dry rot to start. But we need to look at the whole plant to see where it is soft and or discolored.

    Get back with us we will see if we can help

    Forgot to add. You can soak the tree for an hour in water and then rinse with a hose to get all the old dirt off

    It is definitely worth a check for any issues with the roots.

    My first thought with where you are located is that the watering needs and frequency will be immense. Your pot in the photo looks to be very shallow? If so, then there will not be much soil in it.

    I find with many plants when transplanting them into the gritty type mix, they can become somewhat soft (like an old potato, plainly soft) in the caudex. These plants have needed to be watered more. If like this they are best kept in a filtered sunlight situation.

    If leaves are turning yellow on the lower extremities of the plant, this is of no concern.

    We have to balance our soil needs according to where we reside and also how much rainfall these plants will receive.

    With a plant that I have that is like this. When I water it through, within a day or so. It firms up. If left too long between waterings, it will become soft again. After a while it stays firm. The roots need to establish themselves in the new soil.

    I uproot it a while ago did not see anything black but a bunch of roots to the butto are slimy and soggy feeling this was not the case before I repot I never saw this before I will upload the photo what to do I know I should cut off the slimy ones but what about the brown caudex I am thinking maybe it was like that because it was not getting proper water because the roots were damaged

  • 10 years ago

    Also when reporting can I use the same soil and add the different thing s to it or is it contaminated and has to be thrown away

  • 10 years ago

    Your roots look great. That is a good sign. Use alcohol on your blade for each cut so the rot from one won't contaminated the other spots. You can put cinnamon on the cuts to prevent fungus.

    I have had mine give a little at the caudex but once I gave it more water to run through it firmed up.

    You have been having lots of rain. Does it sit out in that? That is why we are concerned about the sand It gets wet and can pack around the roots. They don't mind rain, but the water must pass through. In Thailand they use sun screen so they control the water better during the rainy season.

  • 10 years ago

    Yes it's in the rain but it every couple of days we may get heavy rain fall so even though u use sharp sand and the water drains out fast does not mean it's well drained ? And also Marcia do u think my trunk was like that due to lack of water thanks again for the input

  • 10 years ago

    I am not an expert by any means. I just know that when I transplanted mine the caudex got very slightly dentable. I just started watering through more often, I have very dry heat with a breeze so I tend splash water at it every other day,

    What was your routine before repotting it? Did you use sand before? If you put it right out in the sun after you transplanted it sunburn can be why the color change. I wait about a week before full sun. Transplanting it can be a shock

    Rick I wonder if this should have the roots thinned a little. Wouldn't it give them a better air circulation

    I think the lack of water may not be the problem but the frequency it gets water. High temps can really dry things out. Since the bottom roots got soft, does this pot have a catch dish under it? That could leave the roots in water to long. Instead of draining through.

    just wanted to update you guys

    I left it out of soil for the last 6 days someparts of the trunk to the buttom started becoming a bit soft gave it a bareroot in superthrive before I repotted hope all goes well now I added more soil to my mix because you all were right it took a long time to dry out and it's consistency was that of wet beach sand. Also added grits and aquarium gravel because I don't get perlite where I am thanks again for all of you that posted

  • 10 years ago

    I am also noticing the khaki color on the newly lifted roots are peeling off and appearing green under it not sure what that means hope the rest firms back up when I start to water tomorrow

  • 10 years ago

    Sounds like sunburn, keep an eye it that it stays firm and doesn't blacken. Remember slowly back into full sun say a week, Let us know how thing go,

  • 10 years ago

    Really I put it back in sun already

  • 10 years ago

    We usually give it a few days of semi shade. So the leaves and caudex adjust. Hope it stays well

  • 10 years ago

    Ok thanks

  • 10 years ago

    That brownish thing is just scar tissue. Sometimes it does fall off or peel off. Just do not force it off or you will risk re-injuring the plant.

    I must say, you have an awesome plant.
