Overwatered and not enough light +1

Thank you both for your opinions! I got it as a small single head succulent last fall and has been growing well, but recently seems to be unhealthy. I'll try to get more light and less water. I have to find the one who is biting my leaves off too...

A really really etiolated sempervivum.

In case some of you are wondering why the sempervivum, is that aeoniums have flat rosette growth tips, and the leave edge is to narrow. And the leaf margin hairs are smaller on aeoniums as well. Also, ive seen plenty of etiolated sempervivums heres.

I am quite familiar with semps, and still have hard time to be sure. But Stefan is correct about the rosette. Here are few of my semps:

Sempervivums are hardy succulents, and should be grown outdoors year-round. They appreciate some winter sleep :) Soil you have them in is probably water-retaining. Good drainage is very important for all succulents, and that means fast draining mix, and container with drainage holes.

Yeah, usually, thats how indoor grown semperivivums tend to resemble, they get etiolated a lot. Best left outside, since they are really hardy.

I know I'm always saying jovibarba but it looks like it to me lol Probably J. heuffelii

This is what a healthy one looks like:

Either way, that thing needs to be out there in the winter sun. And those holes look like punctures to me. Have you got a bored cat in the house?

Pagan, I have the hardest time telling Jovibarba from Semps. It's kind of an important difference to be pointed out though. Hopefully the OP can get a proper ID (does it need to grow more normally before it can be properly identified?) so he or she can know what temperatures it can handle.

Semps multiply by 'chicks' - offsets growing on stolons; and have different flowers. Semp flowers are star-like, Jovibarba blooms are more bell-shaped (and most often yellowish/creamy color).

Pagan, the issue is that i know that jovibarbas are not that common in cultivation, nor do i think they turn into such weird shapes when in improper conditions.

Unfortunately, none of those ID elements are present in that photo. Except if that smaller head is an offset, it looks like it did that without a stolon, ta-dah. If the OP ever gets it to bloom, we will have some hint. But if that is a J. heuffelii, I doubt it---the blooms look like semps which is why some botanists consider it to be subgenus under Sempervivum instead of its own genus. I'll watch mine this spring, Rina, and try to spot that difference which, if there, was invisible to my cursory checks.

I disagree that jovibarbas are uncommon in cultivation (a lot of semps sold in random nurseries are often mislabeled as semps but are actually jovibarba) and the species I mentioned does look like that when indoors, a mistake I made when I got too busy to plant them outside after they came in the mail.

IDs do get tricky though and I wouldn't go to the mat with mine. And it's too cold to be shooting pics outside.

I own both. I can tell you this, in wholesale and retail, there are at least 10 semperivvums for every jovivarba there is. As for ID-ing , i even happen to own a j.heufelli myself, and it it would be slightly more concave, than a sempervivum.(i know the difference because ive seen jovivabarbas have different flowers, and produce offsets differently) I dont think it would look like this , more likely it will dry out.

Thank you all for the very informative discussion! Im not sure if I can get it healthy enough to bloom, but I will try to get as much direct sun light as I can. My room only gets direct sunlights in the morning and I do not have access to outside soil since I live in an apartment :/

As for the question about the holes, I do not own any animals that would make this kind of punctures on my leaves, so it can't be any pets that made the holes. Maybe it could be pests or a disease? They are definitely spreading as time passes.

I'm pretty sure it's from edema from too much water being taken in by the plant from staying wet too long. The substrate you are using would probably be okay outside where it would dry much faster.

If you don't find a way to put the plant outside, it likely won't survive. These plants need to be outside.

Oedema/edema is one of possible causes. It happens when plant takes in more water than it can naturally transpire. Usually, small pimple-like bumps form and turn ito harder, brownish bumps. They could be small splotches too. On very soft leaves, skin could became very 'papery' and holes could form. Sempervivums should not have such soft leaves - but they could be if overwatered.

Sunlight is important for most succulents, and typical recommendations are min. 6hrs/day, preferably more. Maybe you should consider some supplemental lighting (many of us living in cold climates use them to overwinter plants), or rather grow plants that have lower light requirements - Haworthias and Sansevierias are some of the succulents that may do better for you.

Btw, semps are monocarpic: once rosette blooms, it will die after flowering is finished.

Anybody know what these are that are killing my succulents and how to stop them?
