My cactus is softening from the root uo. I don't believe it was over-watered. Perhaps a chill? At any rate, how can I save it - or part of it? Can I cut the green top and re-root?
can you post some pics of it? does the container it's in have drainage holes? what kind of soil mix is it in? when was the last time it was repotted? what heat and sun light conditions is it in? over watering issues can take time to appear - sometimes it can be a couple months before the damage is evident. really helps to have some pics to see exactly what is going on...
