Coral Cactus Plant Care Guide
1. Light Requirements
- Place in bright, indirect sunlight.
- Avoid direct harsh afternoon sun as it can burn the leaves.
- South or west-facing windows are ideal.
2. Watering Needs
- Water only when the soil is completely dry.
- Overwatering can cause root rot.
- During winter, reduce watering as the plant goes semi-dormant.
3. Soil Type
- Use a well-draining cactus or succulent mix.
- You can mix perlite or sand with regular soil to improve drainage.
4. Temperature & Humidity
- Ideal temperature: 60–85°F (15–29°C).
- Keep away from frost and cold drafts.
- Normal indoor humidity is perfect.
5. Fertilizer
- Use a balanced cactus fertilizer once a month in the growing season (spring and summer).
- Avoid fertilizing in winter.
6. Pot & Repotting
- Choose pots with drainage holes.
- Repot every 2–3 years when the plant outgrows its container.
Propagation of Coral Cactus
Coral cactus cannot be propagated like normal succulents because it is a grafted plant. If the graft fails, you’ll need to regraft it. It’s better to buy a new plant instead of trying to propagate at home.
