On a sad note... i have over watered my cactus! The only living, loving thing in my dump of an office.
There is a little pool of water sitting on top of the soil, this can not be good!
I once had a smaller cactus, which I over watered, and when I went to transfer it into a bigger pot, it was really soft, and had turned into a jelly substance...so gross.One would have thought I learned my lesson, which I obviously have not.
I'm just not going to water it for a week, maybe two, and hopefully it doesn't turn into jelly!
