You don't even really want the soil to be moist with succulent plants. Their roots are incredibly effective at soaking up water like a sponge, and their stems (and leaves, if they have them) are like balloons. Just like balloons, they burst if overfilled.

Plants don't really pull in water with intention, so they're not going to take only the amount they need. If you've overwatered a succulent you can't just leave it in the pot and hope the water dries up. It's just gonna keep soaking it up and damaging itself so you need to remove it from the pot and get the soggy soil off of its roots. You'll wanna do this maybe every couple of weeks or so.

These plants have evolved to need little water given incredibly sparingly. For little baby ones, an eyedropper of water might even be too much. The trick is to soak the water but make sure that it all gets soaked up ordries really quickly, within a couple of hours at most. The soil should be pretty gritty and a bit loose. Not like you'd see for regular plants.

I don't really understand these dudes. Succulents are wack. They're not even all in the same family, they're just a bunch of random plants from different families that all evolved to do the same wild shit. If you have a lot of trouble with them like I do, try air plants instead.
