Pachycereus pringlei grows in light shade exposure when young but prefers full sun when adult. The winter temperature should not be less than 3 ºC.

Young cacti need a soil based on decomposed leaf mulch and coarse sand in the same proportions but when they are adults it's convenient to add some clay to retain moisture.

Water moderately at the rate of once a week in summer, in spring every 12-14 days, in autumn every 20-22 days and do not water in winter.

Fertilize every 30 days in spring and summer with mineral fertilizer for cacti. Fertilize with compost in early spring when they are adults.

They are plants resistant to pests and diseases but sensitive to excess watering.

They are propagated from seeds sown in spring; Propagation by cuttings is a slow and complicated process.
