How to fertilize Mammillaria Compressa
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 Mammillaria Compressa after it doubles in size or once a year—whichever comes first.

I just saved this cactus from my grandmas house from what she said i think she maybe over fertilized him, and kept him in a non drainage hole plastic pot. i let him sit for 3 days to get used to his new environment. just today i put him in a new unglazed clay drainage pot…. i noticed when repotting him his roots were a bit orange but long, most of his spikes are black and, he’s also partially brown.. my question is i guess if theres anything else i should do to save him?

my nana gave me a cacti and it’s brown and i’m not sure if there’s something wrong with it. my nana was gifted a cactus as a house warming present and about 7 months later she gave it to me…( i had never seen it previously) and it’s brown right in the middle but only in the middle.

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!
