Finding light for Cactus in your home
Cactus love being close to bright, sunny windows 😎.
Place it less than 1ft from a south-facing window to maximize the potential for growth.
Cactus does not tolerate low-light 🚫.
Select your region to see how the current weather in your area affects the placement of Cactus in your home 🏡.
How to fertilize 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 Cactus after it doubles in size or once a year—whichever comes first.

Why is he so wrinkly? ☹️ Hellooo! I recently reported these tiny cactuses on a bigger pot. Two of them look nice, bit this little one looks ‘deflated’? I’m not watering them as much as Greg suggests as I thought it could be an overwatering issue… but it’s not changing… it looks sad and wrinkled… Does anyone know why or what should I try? Any advice will be highly appreciated ☺️

Why's it so small and yellow at the bottom? (I'm repotting for a friend.) It's not squishy and the roots look healthy, so what's wrong with it? The pot it was in had no drainage and she top waters... I've asked her to get a terracotta pot and told her to water from the bottom from now on.... Anything else?

I potted the arrangement backwards (oops 🫠) but I finally repotted my friend's cactus! The pot she gave me was too big so I threw some other things in that can survive on a cactus watering schedule... #WickedValkyrie #happyplants #plantsmakepeoplehappy #plantaddict #cactusclique #succulentsquad #socalgreg #socalcacti #socalsuccs

Is this the correct type of cactus? I had the app scan my little cactus Leo today, but I’m not sure it it’s totally correct. The closest that I could find was a Sonora Barrel cactus… I just want to be sure of what type Leo is. If anyone knows, that would be great. Thanks!

What are these white spots? Any idea, what these white spots are? Should I worry. Is it some kind of pest? What measures should I take? #cactusclique

Is this sunburn on the top of the ribs? I noticed they yellowing shortly after receiving the cactus and have been moving it away from my grow light. It seems to have improved slightly but I'm unsure with how localized the discoloration (directly on top) when the light is actually to the side of the plant. Edit: sorry I thought it would show post would show the picture of the cactus I uploaded when adding it., see comments for photo
