Black-eyed Susan is native to North America and is a perennial herbaceous plant, often cultivated as an annual or biennial. It is highly adaptable and relatively cold-tolerant. It is easy to grow, drought-resistant, and not very demanding on soil, but well-drained sandy soil should be chosen. Black-eyed Susan prefers a sunny and warm growing environment.
1. Soil
Black-eyed Susan is not very demanding on soil, with a strong adaptability. It is suitable for planting in well-drained, loose, breathable, and fertile sandy loam.
2. Temperature and Light
The optimal temperature for the growth of black-eyed Susan is between 10°C and 30°C. Maintaining the appropriate temperature allows black-eyed Susan to continue growing and flowering. Regarding light, black-eyed Susan enjoys a sunny environment and requires ample sunlight during its growing period to thrive and produce vibrant flowers. In the summer, with strong sunlight and high temperatures, black-eyed Susan should be provided with appropriate shading and cooling measures, such as spraying water. In winter, with low temperatures and less sunlight, black-eyed Susan should be placed in a sunny indoor location for maintenance and kept warm.
3. Watering and Fertilizing
Black-eyed Susan is not very demanding for fertilizer and water. Watering generally follows the principle of watering when dry and keeping it moist when wet. During the growing period, black-eyed Susan requires a larger amount of water, so water should be provided appropriately. During the bud stage, the potting soil should be kept moist, with sufficient watering in the morning or evening. When black-eyed Susan is flowering, watering should be moderate to prevent the plant from falling over. For fertilizing, in addition to adding a base fertilizer during planting, usually only top dressing is needed when the plant is growing well to supplement missing nitrogen, phosphorus, and potassium elements, ensuring adequate nutrition. During the flowering period, the application of phosphorus and potassium fertilizers should be increased to make the flowers more vibrant.
4. Propagation
The main method of propagation for black-eyed Susan is division, but it can also be propagated by播种 (播种 means sowing) in spring and autumn. Additionally, tissue culture and cutting propagation are also used.
5. Pruning
During the growth of black-eyed Susan, pruning is often required. During the growing period, timely pinching is done to promote branching and increase flowering. When the leaves are too dense, the old and diseased leaves should be pruned to make the plant more beautiful and improve lighting and ventilation conditions, reducing the occurrence of diseases and pests.
6. Diseases and Pests
When cultivating black-eyed Susan, it is important to note that the plant may suffer from root rot or leaf spot diseases, and timely pest control measures should be taken.
