I water similar to Stush2019 I'm in zone 6b. I do have some that I leave outside that have just had 6 in. of rain this week. I do not use saucers on them. I rarely lose one. I try not to use glazed pots for my cacti. I've lost several in them. If I do use a glazed pot, I always check with a moisture meter. If any reading at all, I do not water. Pictured are some that I plant each year that do very well with the amount of rain and full sun.
