Pot Selection

Sunlight

Watering

• Winter: Every 20–30 days or less.

Never leave the pot sitting in water.

Fertilizer

• Feed once every 4–6 weeks during spring and summer.
• Use a cactus fertilizer or balanced liquid fertilizer (half strength).
• Do not fertilize during winter.

Repotting

• Repot every 2–3 years or when the plant outgrows its pot.
• Repot during spring for best results.

Propagation
