Its hard to see the stem in these photos, too dark. Some plants as they grow shed their lower leaves but I cant tell for sure if its age or something else. Also is it getting enough fresh air?

Here is a better picture of the stem. I think it seems to be fine but I'm not an expert on succulents at all. I have all my plants on a screened in back porch with lots of light so I think they're getting enough fresh air

The soil your plant is in looks really wet in the photo - if that's the case, water-retentive soil is causing the problem. Is there a drainage hole in that planter?

That is way too long for succulents.

Would you suggest planting this one in a different soil then? My other succulents are in the same soil and they don't seem to take as long to dry out between waterings.

All succulents will benefit greatly from free draining soil/mix. Sometimes it is difficult to tell for sure if the soil is wet or dry - on inside. Top of the soil may look dry, yet center and very bottom could be mucky. I don't know if that's happening to your plants, I am just saying what happens quite often.

Succulent potting mix shouldn't stay wet for 2 weeks, not even 1. They like to dry out between watering. Actually, they are better under-watered than over-watered. In their natural habitat, they get little rain, sometimes moisture from fog only. They store lots of water to last during dry periods, that may be long.

Many of us use mix of ingredients that have larger particles: perlite, grit, scoria, pumice, turface and few more. This gives them great drainage and allows for air-circulation. Depending on your location, some of these may be more difficult to find. Perlite is available just about anywhere (Lowe's, Wallmart, Home Depot, any garden center...) Soil bought in bags has very fine particulates that compact when wet and take long time to dry out. Peat is also hydrophobic - when it dries out, it is difficult to re-wet. If watered constantly, it holds water for too long, so many succulent growers eliminate it.

If your plants have many leaves getting yellow and looking water-logged, or developing blackish spots and leaves falling off, it is likely caused by constantly wet soil (older leaves will naturally dry and fall off, but not too many at the same time.)

Can you post photo of whole plants and maybe your other succulents? And what general location are you (or grow zone)?

Here's a full picture of the succulent I'm having problems with. I'll also post a picture of my jade plant which was the first succulent I ever potted in this soil and I think (again, I'm not an expert) it's doing well. I don't remember what brand of soil it was, but it was made for succulents and cacti and seems to have some perlite in it.

I live in upstate New York and the only problems I've had with my succulents so far have been related to light (as you can probably see by the picture). I have them all placed on my back porch which is screened in and gets a lot of light.

By the way, I just watered my jade yesterday as well. This one dries out within a few days, but I still wait at least a week to water it.

Lillykatea- Your plant looks similar to mine. It's a small echeveria 'dondo' and mine is grown in full sun and it still stretches a bit. On mine when i do notice the stretching and some leaves start to fall off it's because little babies are starting to sprout.

It may be hard for you to see but on the lower left ...is a new little sprout. The other side which i should have taken also..has about 3 new sprouts. It may or may not be a natural happening with this particular plant. It's my first 'dondo' so i am not certain. Maybe someone will tell us.

How cute, all 'huddled up'.

Looking at last of your photos, I still can't tell what exactly is happening to your plant #1 - few leaves look like they may have little sunburn and few look like there is some fungus, similar to powdery mildew. Don't be alarmed (yet) because I am not sure if it is fungus, hopefully someone else will be able to diagnose.

I don't want to sound 'pushy' or worse, but if my plants, I wouldn't keep them in soil yours are in. Jade can take little more soil, but I found that with grittier mix, the results are considerably better for succulents. JMO of course, and it is your decision how much you want to get into 'mixes' - it takes little effort to get the ingredients and definitely not everyone is willing or able to do that. And I know that buying in smaller amounts, everything is more expensive.

Thanks Rina : )
