When we’re growing our lovely adenium desert rose, sometimes it will grow strong & beautiful, and other times it will get sick and need our help.
We know how it feels when seeing your beautiful babies getting sick & weak. But don't worry. Putting on our Sherlock hat with a magnifying glass in hand, together let's find out how to fix:
1. Petals Tearing Apart
Diagnosis: You can notice this happening when the flower is very young—usually when it is just a bud.
The usual desert rose flower will grow up with each of the petals closely attached to each other, forming a nice smooth tube.
In this case, however, you will see one or two petals tearing apart or separating from the other petals. Thus, no tube can be formed even when it grows bigger.
On the same branch, you may see one bud with torn-up petals like this and the others still growing strong and healthy.
Quick Fix: One potential idea is the genetic variety of the plant you’re having. This may just be one of nature’s diverse makeups & it's perfectly normal.
Also, check the amount of sunlight you're giving your baby. Desert roses love full sun–the more, the better. Without enough sunlight, leaves & flowers cannot form beautifully.
Check if there may be any deficiencies in the plant's diet. The lack of phosphorous, a macro-nutrient, will affect flower & fruit development. With enough potassium, your flowers will grow stronger & with brighter colors.

Be sure, also, to give the adenium more water during the stages when it develops leaves and flowers. Producing those beautiful flowers and foliage requires a good amount of water.
One of the desert roses we have here in Zenyr Garden is currently having the same issue of torn-up petals.
We will try to experiment with some of these ideas and get back to you with the results we find. In the meantime, you may also want to have fun carry out your own experiment. We'd love to hear about the results from you as well.
2. Leaves Curling Inward At the Tip
Diagnosis: We have checked out some other sources about this issue. Some gardeners have experienced the same thing. From their experience, this may just be normal growing, and it should not affect the overall health of the desert rose.
If you only see one or two leaves on the plant curling up while the others are still in good shape, it may not be a big deal at all.
From a more technical point of view, the issue with leaves curling up may be the result of a potassium or nitrogen deficiency.
Potassium is another macro-nutrient that is responsible for stem and root growth. Nitrogen is good for green, healthy leaves.
Quick Fix: We may try adding some more potassium and nitrogen by planting in some beans or putting some composted kitchen scraps into the soil.
This way, we can then wait and see until the next round when the plant produces leaves and get better results. As always, patience pays off.
3. Leaves Turning Yellow
This is probably one of the most common issues with desert rose. According to some growers, you may be over watering your plant. There’s an easy way to know this.
When you touch the adenium caudex, if it's too soft, then it is lacking water. If the caudex feels just right, then it’s good. If it's too hard, then you may be giving it more water than it needs.
The tree will also tell you by giving you signals. If there’s too much water, you may see some spots popping up on the caudex—just like pimples. The tree has to create exit ways for the water to get out.
Look for these spots:
When you see this, you need to reduce the amount of water. Or putting the plant somewhere else with more sunlight so it can use up the water it is storing inside. Pick the desert rose out of the soil, cut some parts of it roots, and hang the tree up to let it dry out.
Try touching the leaves. If on a gentle touch, the yellow leaves fall off almost immediately, then they are simply old yellow leaves, and everything is in its normal cycle.
However, if you try touching or pressing down on the leaves a couple of times but they won’t fall off, then those yellow leaves may not be old leaves. Rather, they may be young leaves experiencing some issues with water or diseases.
If you’re under-watering the plant, its caudex or the whole plant may start to shrink. Touching the caudex, you will feel that it’s way too soft. But don't squeeze it too hard because that might damage the tree tissue. Then, you know you need to ramp up the amount of water.

4. Roots Getting Rotted
Root rot is an issue that may be related to our yellow leaves. Because the roots may be over watered, they burst out the components inside them and become quite mushy.
To find the rotted part of the roots, you may want to look at the yellow leaf. Then, trace it all the way down to the stem and the nearest roots around that branch.
Use your hands to touch and feel the root system. If it is rotted for only a small part, then cut the part out. And apply some garden lime powder or cinnamon on to heal the scar.
If you see black spots on the roots or they are severely rotted, dig your plant up, cut the rotted roots out, and hang it upside down in some place with shade. Spread some lime powder or paste on for healing. When the scars heal, replant the tree into the soil.

If you don't like using the garden lime powder, here are some other super cheap sealants you can try:
There are some other ways you can try to get rid of the rot:
- Use a high-pressure garden hose to blow the rotted part out
- Soak the rotted roots in lime liquid to kill the harmful bacteria
- Use a spoon to scoop out the rotted part

5. Soft Adenium Caudex
Soft adenium caudex may be caused by movement shock during shipping, especially for grafted desert roses. It may also be damage from dropping, which causes some bruise. The plants may be dehydrated, under-nourished or under root fungal attack.
To save your babies, you may need to temporarily cut off big energy consumers. By that we mean, cut off those leaves, flowers & small branches. Then, snip off some mushy, black string roots (if any). Dig your plants up & let it rest for 7-21 days. No water during this point.
After the resting period, place your plants in fresh, cool growing medium for its recovery. Give it some water. This recovery process can take up to 3 months or more depending on the strength of your trees.

6. Other Leafy Issues
Here are some other issues adenium lovers have also shared:
Weirdly shaped leaves
As you can see, the leaves in this case may be doing what we call, self-eating (autophagy). It shrinks back in size from either one side or on some particular part of the leaf.
A question our inner child or the inquisitive kids may ask is: Where did that part of the leaf go? Our best guess in this case or in any cases where you see some drawing back of some parts of the plant is deficiency.
Something or some nutrients may be lacking somewhere, and our adenium has to cut back on a few parts to move the nutrients to the places where it thinks are essential to sustain the life of the plant.
If we continue with this size, we may not have enough to distribute to everyone. This signals to us, as the loving and thoughtful gardeners, that our plants may need some nutrient boost.
Shorter or medium-long branches make it easier for our tree to pump water up and nourish the top-most parts of the plant.
Insect attacked leaves
Our young, fresh adenium leaves are yummy treats for the worms, bugs and comfy homes for other insects to lay eggs.
When you see tiny red dots clustering up on the leaves, you know your leaves are being visited by an unwanted visitor called the red bug or red spider mite.
To ask the visitors to leave, you may want to take a drastic approach and spray some chemicals like supracide, kelthane, or tribon on both sides of the leaves.
If you notice only a few caterpillars or little worms on the leaves, you can pick them up by hand. Don't forget to wear gloves if you don't want to be yelled at by your loved ones.
If there are too many of them, you may try spraying chemicals every 10-15 days. Just cut the infected leaves off the branch and put them in a garbage bag somewhere far away from your growing area.
When seeing the eggs, but the mom is not there, we may wonder: Where did mama go? One thing we know for sure is she must not go very far. She must be sticking around our area somewhere, but we haven’t spotted her yet.
Speaking of bugs, we have found this creature near our desert rose. Do you think it’s a bug or something? Looks naughty.
Update: We've asked the folks over at Reddit about this creature. From their experience (which is obviously much more than ours), this little guy is a yellow stinky bug. Fortunately, they don't bite or sting–phew. But the specie can be very invasive.
White spot on the leaves
We notice this white circular spot on one of the leaves. To be honest, we currently don’t know what the causes for this might be. We put it up here to share our experience and to see if anyone has any ideas for what might be happening.
Final Checklist for Healthy, Happy Desert Roses
• 100% sunlight
• Water more on flowers & leaves days
• Nitrogen, phosphorous, potassium all good
• Good air flow & drainage
• Check for weird red, white, black dots on both sides of leaves
• Feel the hardness of the caudex & branches
• Give it a nice “hair cut” after flowering to toughen it up
• Check the surrounding for any weird insects or organisms
• Give your love to desert rose every day
We know, we play music to our plants and kiss them “muah muah” every morning. No, we don't. Okay, maybe we do. So much for the love of an resilient, elegant tree.
Don't Worry, Your Desert Rose Will Recover!
Don't be sad, okay, everybody has issues with their trees at some point. Just like when we’re raising a kid, there are good desert rose days and bad desert rose days.
During hard times, when the plant can’t seem to be strong enough to fight on its own, it may be calling for our help.
As caring and smart gardeners, we’d want to make sure we understand our unique babies enough to help them and not make matters worse.
Very often, what’s showing on the surface might suggest problems stemming from the underneath, that is the root. If we take a more holistic approach to caring for our plants, we can see how the sunlight, the water, the food, the air all affects them.
Having an adenium with issues is interesting and offers a unique learning opportunity. It’s the fun of our gardening process, so enjoy! If you have any questions, let us know. Have a beautiful day.
