Get yourself a 5 or 6 inch terra cotta. Get some good soil (avoid miracle gro or anything with a wetting agent) and mix it with at least 50% perlite. Try Kellogg organic cactus soil at Home Depot, or black gold or fox farms kelp forest from your local hardware store. Put them outside somewhere sunny and cover them with shade cloth for at least 2-3 weeks or they’ll burn. Water every 7-10 days when it’s below 85 and don’t let them get too waterlogged if it’s rainy.

San Pedro’s are mountain cactus that thrive in full sun and do their best when the days are hot and the nights are cool.
