Adenium obesum (Desert Rose) Leaf Disease

17 years ago

Hello, thanks in advance for any help. Here is a picture of a leaf on my Desert Rose, which really seems healthy in all aspects other than the brown patches on some leaves. First it was just one leaf, now I notice it on several. I have Garden Safe brand fungicide/pesticide and thought about spraying it but thought I should try to identify what it is first and see if it is even ok to spray the Desert Rose like that since it is a succulent. Any advice would be greatly appreciated, let me know if you need more info. Thanks!

When is the last time you had a good, reliable soil test done? That might possibly be a nutrient deficiency rather than a disease.

I would assume that it's a potted plant. So I wonder the value of any sort of soil test for just one plant.

I would suspect that the problem is environmental/cultural. Depending upon where you live -- why do folks only say United States? -- would determine its activity level. In any event, the plants would be dormant at this time of year.

Beyond that, this succulent plant does well when the potting mix (or soil) dries a bit.

Further, how long has it been in the same pot? Perhaps it needs to have the potting mix renewed. If so, a fine time to do that is just prior to when growth resumes -- in other words, when the weather warms considerably.

Hi, Ive also been having some trouble out of my Adenium Obesum. But as I am looking through some of the suggested caused and cures. I am finding it a little hard to compare since there are a few differences. I purchased my Adenium Obesum about a month ago online. It arrive healthy, about 2.5-3" tall green and healthy. She was obviously grown from seed since she has the infamous fat trunk. I done a little research before purchasing the plant. I got to know it like dry arid conditions, fast draining soil, and PLENTY of sun light. I also read you could train Adenium Obesum to become indoor tolerant. My potting medium is bonsai potting mix, and sand; no course or dead plant material as it is highly susceptible to root rot. Since it has arrive I placed the plant in indirect sunlight but still pretty bright. After about a week or so I noticed a bit of yellowing in a few of the leaves. Come 2 days later it has spread to a few more, a few days later the first yellowing leaves begin to wilt. Then fall off. You get the idea. So now its a month later and I have a most of the original leaves, but a few have fallen off and most haven either yellowed or becoming yellow. I know my water is draining fast, the only thing I can think is light, or the water I am currently using (tap) is not kosher with my Adenium Obesum. Please help, I want to see my little girl thrive. I know Adenium Obesum are such BEAUTIFUL trees, which is why I purchased it to begin with. The situation isnt too dire, but until I get some help I have her placed outside my window in direct sunlight most of the day. Btw I am watering her about once-twice a week. Im still figuring out what she likes as far as water. Remember this is a baby not some of the beauts you guys have posted. Thanks once again, Stefan

Brrian, you should check out the adenium/desert rose forum. Ltran on there is in Houston and has the most amazing collection of big DRs. I've seen triples offered here and there but never quads. There's a link for a place to order online below. George, I went to Joseph's nursery in Pearland and they had a great selection (in June) of DRs, even doubles. I was told they only bring them into the sales areas when they're blooming though I saw lots of giant ones in cachepots that weren't. Definitely worth a call. Laura, like everything else you grow your DRs are looking fantastic! Here is a link that might be useful: DRs online
