Root rot happens when your adenium desert rose plants hold too much water than needed and have no ways for the water to get out. The excess amount of water might attract the bad guys to the party and therefore eat up our plants’ roots.

We understand how upsetting this can be. But there are several easy ways to recognize whether your adenium have root rots and how to save them properly. Or better, how to protect your babies from future root rots. Come with us & let's check them out now.

How to Know the Adenium Plants Are Rotting?

Firstly, we can start by looking at the caudex. If you see spots like pimples start popping up, then it may be a sign that there’s too much water inside the caudex and the plant is creating exit ways for the water to get out.

Look out for these pimples:

These are the little gateways that are beginning to burst out because of the turgor pressure built up inside of the caudex. From one grower's experience, these are like the about-to-pop-out roots the plant is automatically triggering as the root parts below may be in trouble. As a self-saving mechanism, it also tells you if the adenium may be rotting.

Have a look at the overall caudex shape. If you notice that it is swelling up bigger than usual, then it may also be a sign that something wrong is going on underneath.

Here is a caudex that shows signs of swelling up:

Also, use your hands to gently touch and feel the caudex. Is it too soft or is it too hard? If the caudex is too hard, you know that it has built up a lot of water. And like a balloon and may go burst soon.


Another small sign you can look for is the yellow leaves. When you press down on the leaves multiple times but they won't fall off, it may be root disease that eventually leads to root rot.

What you can do is trace all the way from the leaves, along the branches, and down to the root around that area—just like following the blood veins from your wrist to your heart. Then, you can narrow down where the troubled area might be.

When some roots are rotted, it makes the water and nutrients transportation very weak around that local area. If you go backwards and trace it back, you may find some rotted roots down there. The rotted root will be black & mushy.

One other way to tell is: when you prune back the adenium branches, the new leaves develop very slowly and small. A healthy tree may sprout 2 weeks after pruning. This may tell you that the roots are not developing or may be having some challenges pushing nutrients up. It's a good time then to dig your plants up to see if we can save it.

Adenium Root Rot: 7 Ways to Handle

1. Cut the Small Rotted Part Out

Slicing the rotted part out

If the rotted part is small, simply cut it out using a bread knife or some cutting tools you have around your house.

After cutting, apply some cinnamon or garden lime powder onto the cuts. This helps heal the wound and protect the fresh cuts from any potential damages from water or bacteria.

2. Cut a Big Chunk of the Root & Caudex Out

If you see black spots that are quite mushy on the root, just cut them out. To avoid the root from being deformed, you can try cutting the whole thing evenly.

It is a good idea to sterilize your tools with alcohol before doing the surgery. After you cut the rotted root out, use some cinnamon ground, fungicide or lime powder to cover them up.

3. Use a Powerful Garden Hose to Blow Out the Rotted Part

If you don’t like cutting up your caudex, you can try using a high-pressure garden hose to blow out the rotted part. Doing it this way saves more of the unaffected part and you don’t need to sterilize any tools beforehand.

4. Use a Spoon to Scoop the Rotted Root Out

If you want a gentler approach that can save a lot of your caudex, then try using a spoon to scoop out the damaged part. This method is simple and effective albeit might take a bit more time than the other drastic methods we’ve seen.

5. Soak the Plant in Fungicide Solution

When digging up your desert roses, try first to soak the plants in a fungicide solution to kill off some harmful bacteria on it. If strong chemicals are not your thing, try something gentler like the lime solution or ginger-garlic-chili solution. Onion also works quite well.

6. Let the Plant Dry Out in the Sun

After cutting out the black parts and applying some protective powder, just lay the plants bare roots outside under the sun for them to heal.

Check your babies every day to see how they are doing. Once the roots have become harder, it is a good time to plant it in the soil again.

7. Replant Your Plant Into New Soil

Once your plants have healed and everything seems more stable now, you can replant them into the soil.

Some growers use root hormone to promote the formation of new roots. Even after this replanting, you should check the root system to see what’s going on every day.

Don’t water your plant just yet. Make sure the soil is nice and dry. Once you see some little strings start shooting out from the root, you know the plants have started growing again. And they like their new home.

At this time, begin watering them lightly. When they grow stronger, increase the water and nutrients amounts.

Responses to Readers' Questions

What protective powder do you recommend please.

--> Dear reader, it has already been stated in the post. I will repeat here once again for you: lime powder or cinnamon powder.

When waiting for the new roots to start developing, should it be in a shaded or sunny location?

--> Thanks for your question. You can keep it somewhere with light sunlight (about 30-40%). Keep out of rain and make sure the plant doesn't move. When signs of growth have started (roots taking, leaf sprouting), you can move it to 100% sunlight and water it again. I hope this helps!
