How to fertilize Mammillaria polythele 'Inermis'
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.

The base of this baby cactus I got last weekend is brownish. I just don’t want it to get worse or take over the plant. Does anyone know what might be wrong or have any suggestions? #Mammillaria

Can I repot a spiny pincushion while it's blooming? #Mammillaria Not pictured but my spiny pincushion has been slowly blooming over the past month and its flowers are just now opening up. Its roots have been trying to escape through the bottom of the plastic pot it's in for awhile and I'd really like to give it more space and a better pot than the one it came in. Will I do much harm to the plant if I repot it now? Should I wait until it's completed it's bloom cycle? Im just worried that waiting out such a slow cycle may be risking issues - it really wants more space to grow! Thanks in advance!

One of my babies decided to rot completly and just die. Well, woke up, looked at my babies and saw that Sigmund was about to collapse from rot. I mean... this plant. Everything is fine, then one day he thinks: well, it's a nice day to die. Bye. ☠ 😂 I was able to grab two babies from Sigmund, put some cinnamon on roots and I'm going to let it callus. Do you think they have a chance? 🥺 #happyplants #plantsmakepeoplehappy #byebye #plantaddict #propagationstation #plantgraveyard #greggang #mammillaria

What type of cacti are these? #Mammillaria I have 2 of these guys that I bought from my local grocery store. They did not come with care instructions. I assume I just treat it like a regular cacti? I’ve done some research & I believe it’s a Mammillaria Celsiana?

This plant is so cute and grows quickly to store water. Easy to care for since I only water it monthly. I originally thought it had spider mites but it just has white fuzz naturally and it’s pretty adorable. I like the lack of spines too! It’s really unique!
