Strelitzia nicolai, also known as the giant white bird of paradise, is a beautiful, tropical plant that can thrive indoors and outdoors if given the right care. Here’s a guide to help you keep it healthy:
1. Light Requirements
- Indoors: Place in a bright, sunny spot. It enjoys plenty of indirect light but can tolerate some direct sunlight. East- or west-facing windows are ideal.
2. Watering
- During Growth Season (Spring/Summer): Water when the top 2–5 cm of soil feels dry. This usually translates to watering once a week, but frequency depends on your home’s humidity and temperature.
- During Dormant Season (Autumn/Winter): Reduce watering significantly, allowing the soil to dry out more between waterings. Overwatering is a common issue during cooler months.
3. Humidity and Temperature
- Humidity: Strelitzia nicolai loves humidity! Aim for at least 50% humidity, although it can tolerate drier air. Using a humidifier or misting can help, especially in drier climates.
- Temperature: It prefers temperatures between 18–30°C and cannot tolerate temperatures below 10°C. If grown outdoors, bring it inside or provide protection during colder months.
4. Soil and Potting
- Use well-draining potting soil with organic matter to help retain some moisture without getting waterlogged. A mix designed for cacti or tropical plants works well, or you can mix standard potting soil with sand and perlite.
5. Fertilising
- Feed with a balanced, water-soluble fertiliser every two weeks during spring and summer. Cut back to once a month during autumn and winter. Over-fertilising can lead to salt build-up, so flush the soil occasionally.
6. Pruning and Cleaning
- Regularly remove dead or damaged leaves to maintain the plant’s appearance and health. You can also gently wipe the leaves with a damp cloth to keep them dust-free and improve photosynthesis.
7. Repotting
- Strelitzia nicolai prefers a slightly cramped pot, which can also help keep its size manageable. Repot every 2–3 years in spring, going up just one pot size to avoid overly fast growth.
8. Pests and Problems
- Strelitzia can attract spider mites, mealybugs, and scale insects, especially in drier indoor environments. Regularly inspect and treat with insecticidal soap if needed.
- Yellowing leaves can indicate overwatering or poor drainage, while browning edges may signal low humidity or underwatering.
With the right care, your Strelitzia nicolai can grow into a stunning, tall focal point.
