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

My cactus has a lot of white tips which I thought was new growth but I now see some black specks on it as well. Can anyone help me determine what might be wrong? Thanks #Mammillaria

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?

What type of pot do I need
-
I have 4 echeveria and 2 cactus plants and they all have FUNGUS Gnats.🤬🤬🤬. I don’t know why. I bottom water them. I only water when the soil is completely dry. They have been evicted to the balcony. I hope they don’t die in this cold weather cause they are staying out there until 2026. Got me around here swatting and fanning like a crazy person😤😤😤😤
