How to fertilize Fairy Castle Cactus

Most potting soils come with ample nutrients which plants use to produce new growth.
By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.
To replenish this plant's nutrients, repot your Fairy Castle Cactus after it doubles in size or once a year—whichever comes first.

is he ready to be repot? hi everyone! me and my mom seem to be at a disagreement on if charley is ready to be repot. he’s looking plump whenever we water him, and hes starting to sprout buds. me and my sister think he’s ready to move up, but my mom says her and her sources say to give him a bit more time. any insight would be appreciated.

What the heck could this be? Should I be worried, or is this just one of those things that cactus does. It does not scrape off or move. I did overwater 2 weeks ago. I watered too soon. I hope she is not sick. #fairycastlecactus #cactusclique #happyplants #pestcontrol #plantsmakepeoplehappy
