Arthrocereus SpinosissimusArthrocereus spinosissimus

Water thoroughly when the soil is completely dry, typically during the growing season (spring/summer). Reduce watering significantly in cooler months (fall/winter) to prevent root rot.

Ensure good drainage and avoid waterlogged conditions at all times.

Pruning is generally not required for Arthrocereus spinosissimus unless removing dead or damaged sections. If necessary, use a clean, sharp knife or shears.

Allow cuts to callus over before repotting to prevent infection.

Propagate by stem cuttings or offsets. Allow cuttings to dry and callus for several days to a week before planting in well-draining cactus mix. Offsets can be gently removed and treated similarly.

Repot every 2-3 years, or when the plant outgrows its container. Use a well-draining cactus or succulent potting mix. Choose a pot slightly larger than the current one with drainage holes.
