well I was able to add the pictures by commenting on my own post? Please help if able I don't want it to die.

I can't say what succulent you have, perhaps a Graptosedum. You need to put it into a pot that allows the water run off, otherwise it can go bad.

Also it seems that is looking for more light.

The plant is branching. Are you saying that one of the branches was knocked off and you put it in a cup of water? If so, take it out asap, as succulents should not be sitting in the water. It may root that way, but there is better chance of it rotting than rooting in water. And the roots grown in water have harder time to adapt to being potted in soil or mix. You can leave the plant growing with the branches, or you could cut them off and pot separately - that is up to your liking.

Your plant should not be potted in that jar - unless there are drainage holes. Is it glass or plastic? See-thru containers are not the best, since the roots don't need light, and light will also encourage growths of algae.

Bottom leaves of your plant look quite water logged in this photo. It would do better in a mix made of some gravel, perlite and very little soil. You could also use turface, pumice, scoria - whatever you can find easily in your location.

And yes, you can comment on your own post as you found out, and you can also edit, add photos or links (and more) to existing post by using 'edit' feature, and/or icons at the bottom of the posts.

Yup, it's a sedum. It needs to be in a fast draining gritty mix or cactus & succulent soil, preferably in a clay pot with a drainage hole(s). I believe a gritty mix would be better for your zone. I would follow Rina's recommendation for gritty mix.

It certainly does look like it's looking for sun...lots of sun. The spacing between the leaves should be tighter (less space). This is called etiolation...the plant begins to stretch in search of sun and the spacing between the leaves becomes larger, creating a lanky as opposed to compact plant.

Be very careful with watering. Both over-watering and under watering will cause the leaves to fall off. I'll let an expert talk about that because I don't grow these in containers. The one time I attempted to do so all of the above happened... LOL!

All the very best to you.

there are drainage holes in plastic container. I moved plant from sun to take pictures. if the sun is out it gets sun all day in that window. I will get a better mixture as recommended and I have many pots. I have to to ALL OF YOU.
THANK YOU FROM THE BOTTOM OF MY HEART FOR YOUR ADVISE. All plants in general mean so much to me and this is the first year I have ever had succulents or "air" plants. I will comment again. what did you mean by letting it root with the plant? I'll remove from water immediately. I've always had plants that you could grow a root from water then put in soil? not with these guys I guess lol. again thank you all so so much.

ok so I'm gonna repot the sedum that's in that jar. have some questions first. I stopped at a just opened nursery (this is where I saw and bought my first succulent) I explained I needed to have a fast draining soil that has perlite in it pumice etc. I would like to know what is gritty mix as mentioned by LatinLady and rina_OntarioCanada or mix made of gravel? I'm so confused what to transplant this plant in. I know pot size but contents is confusing me. please advise. one other thing. as I am removing plant to new pot I'm afraid the branches will fall off. every plant I own I tend to as if it was my little being because it supplies me with the air I breath so I should care for them deeply and I'm trying but never had succulents before.

Gritty mix is 'custom made' - just about all of us make it ourselves. They don't sell it in the stores/garden centers. You may find 1 or 2 sellers by mail (but consider paying quite high price+shipping).

Pls. search this forum - there are countless threads on how to make it, with photos too (type 'tapla gritty mix' - 'gritty mix' or '1.1.1 mix' in a search bar - more than 8,000 threads if you type the first key words I suggested).

Basic ingredients are grit, turface and bark. There are many variations (many of us use grit+perlite+turface) and they differ mostly because of availability of different media and also according to climate - some ppl need more water retention (especially in hot climate).

Branches may brake off when handling, that happens sometimes. Don't worry, they can be potted up too and will grow into new plants. Better breaking off a branch or two than keeping plant in conditions that could, sooner than later, kill it.
