I have not seen this before, but I would suggest bugs.

I'm just posting to push yours above the mass posting.

I would check for insects also. It might be some nutrient deficiency.

Look for tiny cobwebs or little sugar deposits on the leaves. Turn the leaves over and look for bugs there too. Spider mites have been known to cause the leaves to grow deformed.

i had leaves that were deformed on some of my plants and was told that the were Boron deficient. So I bought some boron and used it and it fixed the problem. I'm only new at this so don't take my word but might be worth looking into.

I to have had similar experiences with a few plants in the past. Never totally sure as to what could be the cause. Seemed to have more so when new leaves first merged, then the subsequent ones that followed where fine?

The fertilizer that Laura put me onto has the added micronutrients (boron incl.) and I truly am thrilled with the results over the past few years.

It is Dyna Gro Plant Pro (9-3-6) and combination with Dyna Gro Protekt (0-0-3)

Just bought a 1 Gal as my collection has become just a little on the large side.

Go figure.

Ok, what I have done is:

1. Move the plants in a place tha gets less direct sun just to make sure is not a sun thing (although I don't really believe sun is the problem).

2. I have checked for insects and I have seen some yellow aphids in some leaves. I have sprayed with a pesticide that contains pyrethrin. That caused some black spots on some leaves, I don't know why.

I will now give it some time to see if the situation improves and then i'll ckeck for deficiencies. Until now I gave my adeniums a 6-6-6 fertiliser. I have recently bought a fertiliser high in phosphorus for my plumerias. Does anyone use this in adeniums? Does it help with the caudex?

Elie,. If Laura should see this, she could advise as she has a tremendous collection of Plumeria's and Adeniums. I know she uses Dyna Gro, but would not want to assume she is on her Plumies.

Rick

Another plant of mine has the same problem now, so it's definitely bugs. It's a small Pistacia Lentiscus and the new leaves are deformed in a similar way. So I guess it's aphids after all and as it looks more of my plants are infected.

Glad you discovered the cause!

I also have this problem too. This week I checked my plants with reading glass on....holy cow....so many plants are starting to have yellow aphids and white insects. I spent do much time cleaning each leaves.

I can't seem to eliminate all of the aphids. I have several large mandevilla nearby, and they love them.

I have been advised by a few growers here in Australia that if u want to use Potash to only use it twice a year. One of the growers was experimenting and found that the plants that he did this with, the flower colours were more enhanced. But using potash too much is not good. As for the aphid problem, the plant leaves are too sensitive and get damaged from pesticides. If u want to use a pesticide u should apply late afternoon and then hose off all your plants first thing the next morning to prevent as much damage to the leaves. I haven't tried this myself yet as I havent had an aphid problem yet. I have used a pesticide for spider mite and all my leaves got damaged and fell off as I didn't know about applying late afternoon and hosing off next day. But I have also since learned to just hose off spider mites and problem fixed which I did and it worked a treat.

Hello again, Eliana, on the beautiful island of Cyprus. Wanted to re-post my response to you from another thread:

Cool! You're in zone 10 then, tropical rainforest.

"It was around 1200 BC when Aphrodite, Goddess of Love and Beauty, emerged from the gentle jade-colored sea foam at Petra tou Romiou, a boulder that juts up from the south coast of Cyprus as majestically today as it did then. The name Aphrodite, in fact, means "foam born." She was the most ancient goddess in the Olympian pantheon.

"As you travel around Cyprus you will see how it is touched by the spirit of Aphrodite - a spirit of gentleness, beauty and love. The lissome wings of a dove, a silky poppy, pungent myrtle and fragrant rose: these are all sacred to the goddess. The apple, the sparrow, the shell and the swan...and the planet Venus, the mystical powers of which reach their peak in that loveliest of months, May." --from Cyprus History.

Eliana,

What is that flower in your avatar? They look delicate, but I can't see it that well. Are they yours? Please post a picture--I'd like to see the whole plant if possible.

-Kadie

Hi Kadie, thanks for your interest in my country :) That's κυκλάμινο [kiklamino] in my avatar. It's endemic here in Cyprus and it's scientific name is Cyclamen cyprium. It can even grow between rocks! Now it's not the time to be blooming but I have some pictures of my dad's blooms last winter.

Here is some more information.

Thank you, Eliana.

-Kadie

Eliana, those Cyclamen are among my favorites. Here I have four different forms that I grow in my garden. Of coarse cold hardy as apposed to your cyprium species.

This is cyclamen rapandum.

I have Cyclamen pseudonericum, hederifolium, coum, purpurascens (this one smells so nice).

Here's one of my Adeniums. Just to keep things on track.

This is "Triple Twilight"

I'm late to this thread, but I was searching for deformed adenium leaves. My large tree had perfect leaves all summer long. Now that the day is getting shorter the leaves are smaller and some have scallops on them. It's all the new leaves. I've checked carefully and see no insects. It could be the boron deficiency, so I will try to get some Dyna Gro. It has less light now, but I'm just now setting up my new Mars-Hydro light for it. Hopefully it will be happy enough under it to bloom now that it's gotten a complete makeover this summer. I don't have a pic of the scalloped leaves but will take one if you'd like to see them.

Hi Karen. Not sure how your leaves look like, maybe it's something different than the problem I had. My problem was caused by insects because when I sprayed with insecticide the leaves started getting normal again. Note that at first I couldn't notice any insects either.

Thanks, Eliana. I'll get a magnifying glass to check again. My eyes aren't that great.
