Pot Selection

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

Never use heavy garden soil, as it retains too much moisture.

Light Requirements

• Needs 4–6 hours of direct morning sunlight.
• Bright indirect light for the rest of the day is ideal.
• Indoors, place near a south- or west-facing window.

Watering

• Water only when the potting mix is completely dry.
• Summer: Every 7–10 days.
• Monsoon: Water only if the soil is dry.
• Winter: Every 15–25 days.

Avoid overwatering, which is the most common cause of root rot.

Temperature

• Ideal range: 18–35°C.
• Protect from frost and temperatures below 8°C.

Humidity

• Prefers low humidity.
• Ensure good air circulation, especially during the rainy season.

Fertilizer

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

• NPK 5:10:10 or 10:20:20 at half strength, or
• A liquid cactus fertilizer.

Do not fertilize during winter.

Flowering Tips

• Provide several hours of direct sunlight daily.
• Keep the plant slightly dry during winter to encourage flowering.
• Avoid excessive nitrogen fertilizer, which promotes stem growth instead of blooms.

Repotting

Repot in spring when:

• Roots emerge from drainage holes.
• The soil has compacted.
• The plant has outgrown its pot.

After repotting, wait 5–7 days before watering.

Propagation

• By offsets (pups) produced around the base.
• Allow the cut surface to dry (callus) for 3–5 days before planting.
• Can also be grown from seeds, though this is slower.
