The Cultivation Method of Sudan Impatiens
In home gardening, Sudan Impatiens is highly favored for its colorful and vibrant flowers. Although this ornamental plant, native to Africa, appears delicate, it can bloom all year round if a few key elements are mastered. Through scientific and reasonable maintenance methods, even gardening beginners can enjoy a pot full of flourishing flowers.
Basic Maintenance Tips
Selection of Cultivation Substrate
Temperature Control Plan
It is suggested to maintain an environment of 18-24℃ for daily maintenance, and it can safely overwinter when the temperature does not drop below 12℃ in winter. During the summer, when the temperature exceeds 32℃, placing water-absorbing stones at the bottom of the pot can help cool down. Keeping the temperature fluctuation within ±3℃ during the flowering period can help extend the blooming time.
Advanced Management Techniques
Scientific Water Management
Follow the principle of 'watering when dry and damp': water twice a day in the morning and evening in summer, supplement water every morning in spring and autumn, and change to once every three days in winter. The degree of water deficiency can be judged by observing the leaf condition, and the best time to water is when the leaves slightly soften.
Optimal Light Configuration
Set the southeast-facing windowsill as the best placement position to ensure 4-6 hours of scattered light every day. Use a shade net to filter strong light from 11-15 pm in summer, and it can receive full sunlight in winter. Regularly rotate the pot to maintain a symmetrical and beautiful plant shape.
Nutrient Supply Strategy
Apply a balanced liquid fertilizer diluted 1000 times every half month during the growing period, and switch to high-phosphorus fertilizer during the budding period to promote bud differentiation. Combine with foliar spraying of trace element fertilizers once a month to enhance the plant's resistance to diseases. Note that after fertilizing, it is necessary to water thoroughly to prevent root burn.
Handling Common Issues
Disease Control Measures
For powdery mildew, a baking soda solution (1g/L) can be prepared and sprayed on the leaf back weekly for prevention. Remove affected leaves immediately and spray with benomyl, while also enhancing ventilation. Regularly wiping the leaf surface with a garlic extract solution can effectively prevent pests such as aphids.
Through systematic maintenance and management, Sudan Impatiens can bloom throughout the four seasons. The key is to grasp the coordinated control of temperature, light, and water and fertilizer, and adjust the maintenance strategy promptly according to seasonal changes. It is recommended to establish a maintenance log, recording the plant's growth status and maintenance measures, gradually forming an individualized cultivation plan.
