How to grow Stenocereus pruinosus cactus growing and care:
Dry soil (not too much moist), better to have different cultivars for cross pollinators
What is the best way to start growing? Plant / Seed / Vegetative Reproduction – propagating cutting or daughter plant
How to propagate: Daughter plants mostly need to take care when pull it from the ground you take all the roots, take a plastic spatula or something harder depend the soil and uncover the roots, dig around the plant and better to use air blower machine or wash it with stream (but let it dry after).

Is it necessary to graft or use vegetative reproduction? Yes, yield faster
Difficulties or problems when growing: Spines
Planting season: Spring to autumn, hardiness zone 9b-10a better in spring to summer, hardiness zone 10b-11 spring to autumn and all year in hardiness zone 12
How to plant: Hold the plant in the part without spine it will be easier to handle prevent that the spines get into the skin, it’s prevent to plant it properly and when the plant big and also it might fall, need to locate the cactus possible with papers cover enough that the spines won’t get to your hands, to put the soil need to use spoon or small shovel to push and tighten the soil, when the plant not stable put few sticks from the place that the plant tend to fall in order to support it until the plant establish.
Pests and diseases: Snails, slugs
Pruning season: All year
How to prune: When the plant stop to grow new branches, when the branches grow into each other and it’s hard to pick up the fruits, rotten parts to cut few cm before the infected part
Size of the plant: 3-10 m, 10-30 feet, but in pot can be smaller as designed
Growth speed in optimal condition: Slow growing
Water requirement: Small amount of water and it’s drought tolerant
Light conditions in optimal condition for growing: Full Sun
Is it possible to grow indoor as houseplant? No
Growing is also possible in a planter /flowerpot / containers: Yes, container or clay pot that will be 20-50% bigger (not need deep because the root shallow) for good drainage that important use in the bottom of the container with little rocks like: gravel, lava rocks or pebbles, soil should be cactus potting mix, make holes in the container for good drainage,
Switch the soil after few years: Removing the cacti from their pots, take paper and put slowly the plant on the paper, possible to “help” the cactus with the hands better to cover with papers or plastic wrap, after that prepare again the “little rocks” in the bottom, put part of the cactus potting mix, take the plant with and locate it in the new place, if it’s small take the soil mix with spoon and organize it (not to get the spines in hands) if it’s bigger use small garden shovel and squeeze the soil that the cactus will be stable and won’t fall, sometimes when it’s not stable better to add some stick that will hold the cactus.
