I’ve had ‘Miss Peach’ for 12 years, now.
If you want your cactus (cacti?) to be happy - transplant them into terra cotta pots using Cactus/Citrus Soil. They will reward you with lots of future blooms. :)
Terra Cotta dries out nicely between watering. I water Miss Peach once a week. Cactus/succulents of any stripe like to dry out completely between watering.
Ah hah, so my cacti are doing well because of unplanned neglect. Good to know. I have been going out of town this year for 5 to 7 days in a row. Always water the cacti before I leave and when I return. Forget about them for days at a time when in town.
