How to fertilize Mammillaria mystax

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 mystax after it doubles in size or once a year—whichever comes first.

Cactus Fell over with little rocking My cactus seemed to be fine, but I found gnat like bugs in my plant, all my plants really. But I was rocking my cactus back and forth to see if the roots were sturdy and the bugs didn't get to them. Then It fell over and this is what I saw. I have a feeling it could've been not enough water drainage and just rot. Can someone confirm or deny? Also, is there a proper way to salvage the cactus...Maybe Propagate?

Is there anything that could be done to straighten it out more upright or better to leave it leaning? Looks the pot could be restricting growth at the base. #Mammillaria
