Planting
From Early Spring TO Early Spring
If growing as a houseplant, either soil based or peat based mixture can be used with addition of one-third portion of coarse sand. These plants can usually be grown in 8cm (3 inch) pots until they are 7-10cm (2.75-4 inch) tall. Examine them each spring, however, to see if the roots fill the pots. If growing outdoors in warm climates, Cephalocereus senilis grows in rocky or loose soil which is a fast-draining soil. When planting this cacti amend this soil with some limestone chips for best results.
