Any visible pests on the leaves/in the soil? Do you have them outdoor? From the pictures it looks like pests are eating it away but it might be other animals too. Sadly I can't pinpoint what kind of pests it could be, I've only dealt with mealy bugs before and for that I spray/brush the plants with 50/50 rubbing alcohol daily.

Hi DavidL.ca, yes I have them outdoor. I don't have animals in my house. I guessed it is pests that eating it. I only noticed brown color powdery on the plants.

Thanks for your advice. I will try it.

do you see lots of common house geckos at your house? because my sister's succulent get eaten by mice / house geckos. :(

Hi Kizasugondo,

I never see house geckos. Oh..mice might be. I just realised it attack my aeonium arboreum green and jade. It gave light brown circle marks on the leaves.

Aeonium has a mechanical damage - some animal chewing on it. I can't see any other problem with it from the photo.
"brown color powdery" you mentioned (looks like there is some on the second plant) could be some kind of mold. Are you in humid climate? Do you see anything else on second plant - little 'creepy-crawlies', webbing or similar? (few leaves also have some chewing marks, probably same pest/animal).

Hi Rina,

I found it is not easy to grow aeonium. It is easily attacked by pest.

I live in dry area. Yes, I water those plants too often. I guess it can create a problem too.

Then other that that, my aeonium is a place for the spider to create a web. I am busy destroying the webs.

Do you think a spider can eat the leaves of my aeonium plants? I saw a spider crawling on the leaves today.

'Regular' spiders don't chew leaves & they won't harm your plant; I was referring to other type of insect - spider mites. They would be harmful. They are very small, difficult to see. Best if you google 'spider mites' to see photos of them. The second plant seems to be in worse shape than aeonium, that is what I was referring to. I believe it is too wet.

I really think it is either mice, or gecko or squirrel that is chewing on the leaves. Could be snail too, but they leave a slimy trail; and caterpillar.

Thanks Rina. Thanks Deva.

I learnt a lot from two of you. You are awesome!

Hi,

It seems like there are some snails (small ones) or slugs eating your plants. The dark/brown powder is possibly their waste. If possible, check the plants at night/dark with a light. These animals are mainly nocturnal and it's possible that you can find them "red handed", especially in high humidity conditions. During the day search them at the bottom of the pots: they may be hiding there. Be persistent in your search, as these invertebrates may not be active all nights. If the attacks persist, try to move the pots to another place, not at the floor where snails/slugs are easier to find/move.

Hi Zmoguek,

Many thanks. I strongly believe now, it must be a snail that had eaten my plants. I put some snail baits around all of my potted plants. Hope this will help to prevent another incident.
