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

What’s on my San Pedro cacti? Help! I’m not very familiar with Cacti at all but I’m learning. My cousin gifted me San Pedro cacti for my birthday & shortly after receiving them, they started developing these spots which are starting to make it look worse and worse! 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
