You really know your plants, this one is lucky to have you! If you were able to bring this one back to life, I should be able to keep mine alive!
That's very flattering
Exactly. Another story to further prove how resilient they are. I forgot one of my kalanchoes in my watering "bin" for about a week. It rained almost every day of that week. When I remembered about it, I found a plant with no soil, with a pot separated, floating at the top of the water, and a chalanchoe completely submerged in water. Took it out, dried it with some paper towels, put it in some soil and left it for a week (maybe two). Then I put some more soil, readjusted a bit (because the roots had not held on to the soil, so the plant had drooped a bit), and watered. I did sparce watering for some time, and then started it on the normal succulent programme. It's thriving now as well, and has given me quite a few propagations
