So I have a bunch of my Sans inside, in clay pots, well draining soil, topdressed with a little gravel. I have been letting them go pretty dry, to the point that the pots are feeling pretty light and the soil seems bone dry even a couple inches down. I don't let them stay like this too long, but I still have not noticed any shrivelling or limpness, or death for that matter. So is there a chance I am causing any harm by letting them get so dry for brief periods, or is it ok since they really aren't doing too much growing right now? Thanks for any advice!
