Pot Selection

• Use a 3–5 inch terracotta or plastic pot with drainage holes.
• Repot every 2–3 years or when roots outgrow the pot.

Best Potting Mix

Use a fast-draining cactus mix:

• 40% coarse river sand
• 30% perlite or pumice
• 20% cocopeat
• 10% compost or leaf mould

Avoid heavy garden soil.

Sunlight

• Needs 4–6 hours of bright sunlight daily.
• Morning sun is ideal.
• In very hot summers (above 38°C), provide light afternoon shade.

Watering

Water only when the soil is completely dry.

Summer

• Every 7–10 days

Monsoon

• Only if the soil becomes completely dry.

Winter

• Every 15–25 days.

Overwatering is the most common cause of root rot.

Temperature

• Ideal: 18–32°C
• Can tolerate down to 5°C if kept dry.
• Protect from frost.

Fertilizer

Feed once every 4–6 weeks during spring and summer.

• Use a cactus fertilizer or balanced liquid fertilizer at half strength.
• Stop fertilizing in winter.

Flowering Tips

• Provide bright sunlight.
• Allow the soil to dry between waterings.
• Keep the plant slightly root-bound.
• Reduce watering during winter to encourage spring blooms.

Propagation

• By seeds (most common).
• Some mature plants produce offsets that can be separated and replanted.
