About San Pedro Cactus
A San Pedro cactus is the perfect low maintenance plant for a bright window in your home. Native to South America, they’ve been used in healing and religion for over 3000 years by the Moche and Chavin cultures. They contain the psychedelic compound, mescaline, and although they can be grown as foliage, they are illegal to cultivate for consumption in the US, Canada, New Zealand, Australia, Sweden, and Germany. 🌵

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

I have no idea what this is, so please share any/all ideas and recommendations because this is a super sentimental plant for me & I really don’t wanna lose them 😭 #CacClique #HappyPlants #PlantsMakePeopleHappy #PlantTherapy #PestControl

Does anyone know what type of cactus this is? This cactus was gifted to me so I have no idea what kind it is. It grew super tall so I chopped the top off and potted it and both are doing great! Mom plant even has a new sprout on top. The app identification doesn’t seem right for this one. Anyone know what it is?

I stuck myself on this dude while bringing it home. Even though the spines are small they hurt. Just be careful with this one but other than that care is pretty standard
