Last year was a mixed bag of pots I was using for the collection. Some were plain terracotta, others were plastic, and still others were terracotta which I started waterproofing last May. The plastic pots were an experiment, but I ended up ditching them for a few reasons. IMO waterproofed terracotta has been a blessing, so the March repotting project did what I wanted --
A. making sure that nothing is over-potted these days, and B. also making sure that every cactus is now in a waterproofed terracotta pot. I'm fully aware of what happens when water and nutrients that should be going to cactus roots are instead drawn away by evaporation through porous clay. That extent of evaporation is largely a non-issue, and apparently I was correct about waterproofing. Here's my Gymnocalycium ochoterenae vatteri as I've never seen it before:
Those roots are really working -- maybe too well? Bad habits are continuing to follow me as I water blindly by schedule when I should be paying more attention to what some of these plants are supposed to look like. Don't think the vatteri is supposed to look nearly that plump, so I'm putting it on a no-water diet until it flattens out. (Believe it or not, this is actually going somewhere.

I don't have enough experience with Sulcos to know how plump they should be. The callichroma longispina has a honkin' big set of taproots, although I'm very hesitant to make assumptions about how often it needs water. I'd like a critique on this, so let me know what you think:
I've been watering it every 2 weeks since the beginning of April -- my standard Spring routine unless I already have experience with cacti that don't need it as often. So is the callichroma looking normal, or is it too plump? Now would be a good time to let me know, as I have it on the watering list for next weekend. I'll ask the same thing about my Sulco rauschii, which is the plumpest I've seen so far. Any and all thoughts about this would be greatly appreciated.
Thanks for your help, my friends!
