I medicated my succulents today.
So, hoping that I will not have to write such a sad post as ZEGH had to.
RIP, little cactus.
ZEGH, maybe you could try a Spatifilum or a Tolmiea menziesii. They will let their leaves hang in devastation, when you forget to water them. Bbut, if you make up for that, with an abundance of water, they'll be completely all right couple of hours later. (That is, if you don't let them neglected long enough to turn into hay)
