Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the soil is completely dry. Reduce watering significantly during cooler months to prevent root rot.
Ensure excellent drainage; overwatering is the most common cause of problems for this desert native. Allow soil to dry out between waterings.
Pruning is generally minimal for Pachycereus pecten. Remove any dead, damaged, or diseased stems to maintain plant health and shape. Use a clean, sharp knife or saw for cuts.
Wear protective gloves as the spines are formidable.
Propagation is typically done from stem cuttings. Allow cuttings to callus for a week or two before planting in well-draining cactus mix. Rooting can take several weeks to months. Start in spring for best results.
Repot mature plants every 2-3 years, or when they become root-bound. Use a well-draining cactus or succulent potting mix. Choose a pot that is only slightly larger than the current one. Repotting is best done in spring.
