How to fertilize Tephrocactus geometricus

Nutrient, fertilizer, and repotting needs for Tephrocactus geometricus: repot after 2X growth

Most potting soils come with ample nutrients which plants use to produce new growth.

To replenish this plant's nutrients, repot your Tephrocactus geometricus after it doubles in size or once a year—whichever comes first.

Well, the Cactus Crew is officially in rehab... I definitely have my candidates for most and least likely to survive picked out... Lol Some of y'all might remember me posting about my #paperspinecactus suffering from rot. Well, I followed y'all's advice to the best of my ability with what I had on hand. (Some medical expenses came up so I wasn't able to buy *any* of the stuff y'all have told me to get recently... 😩) 🧚I decided to separate a couple of the pads to increase my chances of still having a cactus when this is all over. 🧚Then I put two in sterilized (dry) perlite with emotional support crystals at the bottom, and one is sitting on top of some river rocks/random rocks I found while living in Oklahoma (also with emotional support crystals ofc). 🧚I will occasionally be misting the ones in perlite (instead of watering them) cuz it seems perlite actually absorbs water and I'm nervous about that. The river rocks will have filtered water in them, kept well below the bottom of the cactus. 🧚 For now they're in a North facing window that gets pretty decent indirect sun all day and a tiny bit of direct sun in the mornings. I may move them to the plant room but haven't decided yet. Wish us luck! Bonus pic of River Song looking pretty covered in raindrops.

Thoughts/advice/opinions?? I noticed some yellowing/wrinkling around the base of one of my #paperspinecactus today... It's not squishy, per say, but it is a bit soft. What little roots it has look just fine, no signs of rot as far as I could see... There's also a wee white/yellow spot on the side of one of the pads... It's been in this pot since October and it pulled right out no problem, but it's little buddy is fully rooted into the pot... Any ideas what's wrong with my lil man? How can I help him? Should I pull them out of the 4" pot they're sharing and try putting them in their own 2" or 3" pots? Should I just leave them till spring and simply just not water them until it starts warming up in a couple months? Should I bring them in for the "winter" since they're so new/young? Help me save my #wishlistplant please! 🥺 (Never fear, my hands are fine, this boi is nice. It's his #angelwingcactus #opuntia neighbor that scares me... 👀🌵) #cactusclique #notsohappyplants #happyplants #plantsmakepeoplehappy #plantaddict #wickedvalkyrie #socalgreg #socalcacti
