Fertilizer

Feed once a month during spring and summer with a diluted cactus/succulent fertilizer. Do not fertilize in fall/winter.

Growth Habit

A branching, upright succulent with thin pencil-like stems. New growth emerges green and may flush orange or coral with intense light.

Pet Safe

Toxic – keep away from pets and children.

The white latex sap is irritating to skin and eyes and should never be ingested. Wear gloves when pruning.

Care Tips

• Use gloves when pruning (sap is very irritating)

• Ensure very fast-draining soil

• Rotate the plant for even growth

• Avoid misting — prefers dry air

• Provide strong light for the best coloration
