Huilan, as a traditional famous flower in our country, is deeply loved by people for its elegant flower posture and fragrant scent. Due to the limitations of the climate conditions in the north, many flower enthusiasts are deterred from cultivating Huilan. This article will introduce you to the cultivation methods of Huilan in the north, helping you to easily grow beautiful Huilan.
Choosing the right variety of HuilanThe climate in the northern region is dry with low temperatures, so it is particularly important to choose cold and drought-resistant varieties of Huilan. Common varieties in the north include 'Da Fugui', 'Cuiyun', 'Yudan', etc., which have strong resistance and adaptability to the northern climate.
Soil selection and preparationHuilan has high requirements for soil and should choose soil with good breathability and strong drainage. Usually, materials such as decomposed leaf soil, peat soil, and perlite can be mixed in a certain proportion. The specific ratio is: decomposed leaf soil 60%, peat soil 30%, perlite 10%. Soil prepared in this way can ensure both breathability and a certain level of humidity.
Lighting and temperature managementHuilan prefers a semi-shaded environment. In the summer, the intense sunlight in the north should be appropriately shaded to avoid direct sunlight. In winter, with lower temperatures, Huilan needs to be kept warm, with indoor temperatures between 15°C to 25°C. If the outdoor temperature drops below 5°C, Huilan should be moved indoors for cultivation.
Watering and fertilizingHuilan prefers a moist environment but dislikes waterlogging. Watering should follow the principle of "water when dry and keep slightly moist." In the hot summer season, the frequency of watering can be increased appropriately; in the cold winter season, the frequency of watering should be reduced. For fertilizing, Huilan prefers acidic fertilizers and can choose between decomposed organic fertilizers or special fertilizers for orchids. During the period of vigorous growth, apply fertilizer once a month, and stop fertilizing before and after flowering.
Pest and disease controlIn the process of cultivating Huilan in the north, it is prone to pests and diseases, including powdery mildew, scale insects, and red spiders. The control methods are as follows:
1. Powdery mildew:剪除 affected leaves promptly and spray with a 50% carbendazim wettable powder solution diluted 1000 times for prevention and control.
2. Scale insects: Use a brush to remove scale insects or spray with a 40% omethoate emulsion diluted 1000 times for prevention and control.
3. Red spiders: Use a brush to remove red spiders or spray with a 20% miticide emulsion diluted 2000 times for prevention and control.
Pruning and propagationDuring the growth of Huilan, it is necessary to trim withered and diseased branches to keep the plant clean. There are two methods of propagation: division and seeding. Division propagation is usually carried out in spring by dividing Huilan and replanting it. Seeding propagation is more complex and suitable for experienced orchid growers to try.
