Photos wold help...

If leaves of succulents are turning yellow and they are soft, they could be water-logged and eventually rot. I can't tell for sure - going by what you said. Post a clear close-up photo pls.

Bagged succulent soil is often not well draining; ppl using it add lots of rinsed/sifted perlite or pumice, mixing them in 1:1 ratio.

If succulent was in wet soil, it may be best not to water it immediately. Judging from what you said, I think your 'new' soil retains too much water for too long.

O lord so I may be killing my echeveria?

What do I do bout the soil situation ?

When I got my echeveria its soil seemed fairly dry.

Hi Bethany. It’s not watering that kills succulents, it’s sitting in water too long that does. It rots their roots. I have both cacti & succulents sitting outside, where it rained for 3 days last week. I did move the cacti under covered porch on day 2 just to be safe, but none died. Remember, in the desert, when it rains, it’s often like torrential rain or a cloudburst. All of my c&s are planted in unglazed clay pots & in a “soil-less mix” of chicken grit (manna pro chicken grit from Tractor Supply), coarse-grade perlite, sifted to remove dust & small particles & turface, also sifted for same reason, in equal ants of each. Turface is calcined clay & can be found at most landscaping places . it’s used alot by sports teams b/c it soaks up water, like so baseball players can play after a rain w/o the field being a mud pit. Rina enlightened me to this soil-less mix. I had to learn to water some c&s more frequently in this mix but b/c of how quickly it dries out, they aren’t likely to rot. My bears paw & echeveria seem to like a little more watering in this mix, as in about 1x/wk in summer. I don’t know what climate you are in. it was 91F here today, good thing I watered yesterday! Also try to keep your pot sizes no more than about 1/2 - 1” bigger around than the circumference of the plants rootball. If you think there is enough ”good” left on your plants to save, you can repot them. Rinse off old soil & lay them out to dry a few days before potting up into the new, more rapidly-draining mix. If you can’t find any of the ingredients I mentioned, a lot of people just pot their c&s up into pumice only. I can’t find any here in the Midwest. its also recommended to use your existing soil that you just bought, buy a bag of coarse grade perlite, sift or rinse it & mix it in at least a 40-50 ratio w/ your soil. I personally think 70-30 would be better, especially if you live in a wetter climate like FL or pacific NW, but if in a drier climate, the 50-50 mix should work well. whatever soil you end up using, please check it for moisture at the bottom of pot before watering again to make sure it’s dry or nearly so. I stick a bamboo shishkabob skewer down to bottom of pot (I get at Dollar Tree for $1USD). If skewer comes out wet, I wait a day or two to water then check it again. Hope this helps!

Rebecca gave very good description of what to do...

I am glad new mix works for you Rebecca! :) Watering bit more often is small price to pay; keeping excellent drainage is important for succulents.

Rebecca that was so much info but it will be put to good use

If I have more questions Ill deff be sure to

Also Rebecca I live in Ohio
