Let's delve into the related content about the uses of black-eyed Susan and the techniques for planting it, for the plant enthusiasts who are interested. Let's get to know more about it.
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-resistant. It is easy to grow, drought-tolerant, and not very demanding when it comes to soil, but a well-draining sandy soil should be chosen. Black-eyed Susan thrives in a warm, sunlit environment.
1. Soil
Black-eyed Susan is not very demanding when it comes to soil. It is highly adaptable and suitable for planting in well-draining, loose, breathable, and fertile sandy loam.
2. Temperature and Light
The optimal growing temperature for black-eyed Susan is between 10°C and 30°C. Maintaining the right temperature allows the plant to continue growing and flowering. In terms of light, black-eyed Susan prefers a sunny environment. Sufficient light is required during the growing period for lush growth and vibrant flowers. In the summer, with intense sunlight and high temperatures, black-eyed Susan should be provided with appropriate shading and cooling measures, such as watering. In winter, with low temperatures and less sunlight, to ensure continued growth, black-eyed Susan should be placed in a sunny indoor area and kept warm.
3. Water and Fertilization
Black-eyed Susan does not have high requirements for water and fertilizer. Watering generally follows the principle of watering when the soil is dry and wet. During the growing period, black-eyed Susan requires a large amount of water and should be watered appropriately. During the bud stage, the soil should be kept moist, and sufficient water should be provided, preferably in the morning or evening. When the plant is flowering, watering should be moderate to prevent the plant from falling over. For fertilization, in addition to adding a base fertilizer at the time of planting, it is generally sufficient to provide additional fertilization when the plant is growing well, supplementing missing nitrogen, phosphorus, and potassium to ensure adequate nutrients. During the flowering period, the application of phosphorus and potassium fertilizers should be increased to enhance the beauty of the flowers.
4. Propagation
The main method of propagating black-eyed Susan is through division. It can also be propagated by sowing in spring and autumn. Additionally, tissue culture and cutting propagation are also used.
5. Pruning
During the growth of black-eyed Susan, it is important to prune regularly. During the growing period, timely pinching promotes branching and results in more flowers. When the leaves are too dense, the old and diseased leaves should be pruned to maintain an attractive plant shape and improve lighting and ventilation conditions, reducing the occurrence of diseases and pests.
6. Diseases and Pests
During the cultivation of black-eyed Susan, it is important to be vigilant for root rot or leaf spot diseases and to control them in a timely manner.
