How to Cultivate Bletilla striata
This introduction covers the cultivation of Bletilla striata and provides a detailed explanation of the methods used for growing this ornamental plant. Let's explore this together.
Bletilla striata, also known as紫兰 (Zi Lan) or连及草 (Lian Ji Cao), belongs to the orchid family. It is commonly used in traditional medicine due to its wide range of medicinal values, including the ability to stop bleeding and reduce blood stasis, as well as to reduce swelling and promote muscle regeneration. Moreover, Bletilla striata is an ornamental horticultural plant with colorful flowers and graceful shapes, offering excellent decorative effects. To cultivate Bletilla striata well, one must consider factors such as soil, light, temperature, watering, fertilizing, pruning, and pest and disease control. Let's delve into these aspects.
1. Soil
Choose fertile, well-draining soil for growing Bletilla striata. Its root system is developed and grows rapidly, requiring loose, fertile soil to ensure robust growth. You can place broken tiles at the bottom of the pot to increase soil aeration, and adding decomposed leaves and phosphorus-potassium fertilizers can enhance soil fertility.
2. Light
Bletilla striata can tolerate shade but not strong light, so it needs to be provided with appropriate lighting in a semi-shaded environment. Six to eight hours of indirect sunlight per day is ideal, ensuring that strong light does not directly shine on the plant.
3. Temperature
Bletilla striata is very sensitive to cold and thrives best at around 20°C. When temperatures drop below 5°C, the plant may suffer frost damage. In winter, it is important to take measures to insulate and warm the plant, preferably moving it to a warm indoor environment for care.
4. Watering
Bletilla striata requires a significant amount of water for its growth, so it should be watered regularly. However, during periods of abundant rainfall, it is important to drain excess water.
5. Fertilizing
Fertilize Bletilla striata every 15 days, usually with dilute fertilizer solutions. The frequency can also be adjusted based on the growth of the plant.
6. Pruning
Bletilla striata grows rapidly, and proper pruning can promote healthy growth. It is important to promptly remove diseased, weak, or overgrown branches and leaves.
7. Pest and Disease Control
Bletilla striata is often threatened by root rot and soil pests like the ground beetle. It is necessary to address these pests and diseases promptly and disinfect the plants during times when fungi are likely to thrive.
8. Precautions
Bletilla striata is usually propagated using corms. When using corms, it is important to choose healthy ones and maintain a controlled temperature environment throughout the year.
