seem to be one of the most sensitive plants when it comes to over watering. Even a couple days with too much water can start these beautiful rosettes on a fast track to rot. It’s generally best to err on the side of under watering succulents if you’re unsure. This is especially true with Echeverias.
To save your over watered plant, start by cutting back on your watering or see if you need to switch to a better soil mixture. If you see black spots on the stem you’ll need to behead your plant and propagate the top. Make sure you cut off any black spots and then give it plenty of time to dry out before replanting (3-5 days). Notice how with the cuttings below I cut off any part of the stem that was soggy or blackened.
