Cultivation methods of Hanlan
Sharing experiences in cultivating the orchid plant Hanlan, the cultivation methods of Hanlan, detailed content will be shared next.
It is difficult to introduce a cultivation method suitable for Hanlan in various regions. Since ancient times, there have been few单独 introductions to the cultivation and management methods of Hanlan. Based on years of cultivation experience, the author has gained some insights and explored some cultivation and management methods. Here, I throw a brick to attract jade, but it may not be completely applicable in all regions.
In order to cultivate Hanlan well, it is necessary to meet the growth conditions required by Hanlan and create suitable conditions for its growth and development during cultivation.
Hanlan grows in deep mountains and dense forests. Its requirements for temperature, humidity, water, light, and ventilation are somewhat different from other orchid species. Hanlan, growing in deep mountains, faces frost or occasional snowfall in winter and high temperatures in summer. However, the mixed forest of broad-leaved trees and conifers or the shade of bamboo forests blocks the intense summer sun and the cold winter wind. In areas covered by snow, the snow acts as a protective layer, and the ground temperature beneath the snow generally does not drop below zero. Therefore, Hanlan chooses to survive in the warm winter and cool summer deep mountains and old forests.
I. How to adjust the temperature for cultivating Hanlan
The main purpose of adjusting the temperature is to prevent the roots from freezing in winter and the leaves from being damaged by high temperatures in summer, allowing Hanlan to grow normally with flourishing flowers and leaves. Adjusting the temperature can also delay or advance the blooming period. Temperature has a significant impact on the flowering period. The blooming period of potted Hanlan is about 20 days earlier than that in the wild mountain conditions. Flowering is related to temperature, and high temperature can reduce the fragrance of the flowers, while low temperature can make the flowers more fragrant and long-lasting. In a greenhouse for orchids, it is necessary to consider increasing humidity and lowering the temperature to adjust the internal temperature of the greenhouse. For greenhouses built on the ground, planting trees or vines nearby can help adjust the temperature and create suitable conditions for Hanlan growth. Planting trees is a good method. Tree shade can block sunlight and reduce radiant heat. Under dense shade, more than 90% of the light can be blocked. Tree shade can naturally adjust light and ground temperature. If the greenhouse is on a high阳台, sprinkling water or misting the area frequently can help cool down the temperature. Because the evaporation of water absorbs a lot of heat. It is also necessary to strengthen ventilation to lower the temperature. When adjusting the air temperature, attention should also be paid to the temperature of the potting soil. If the potting soil is coarse and hard, it will change with the temperature of the air, but the process is relatively slow. Therefore, the temperature of the water used for watering should not be too different from the temperature of the potting soil, otherwise it may cause many diseases.
II. The humidity required by Hanlan must be adjusted
Generally, humidity refers to the humidity of the air, which is also known as relative humidity, expressed as a percentage. Hanlan requires a higher air humidity. In the mountains, the air humidity is high, with frequent rain and mist during the growing season, and the relative humidity is around 90%. Low air humidity can cause the orchid seedlings to be yellow and thin with rough leaves, lacking luster. When the air humidity is suitable, the leaves are clean, green, and glossy. The humidity required by Hanlan during the growing season should not be lower than 80%, and it should be between 65-70% during the dormant period in winter, with higher humidity at night than during the day.
III. Hanlan needs ventilation
In the south, it sometimes rains for several weeks, resulting in excessive humidity. When humidity is too high, more ventilation is needed: using fans or exhaust fans to circulate the air and rapidly evaporate moisture. Hanlan thrives in wet conditions with good ventilation. However, high temperature and high humidity without ventilation can be harmful to the new shoots of Hanlan and can easily lead to various bacterial and pest diseases. Therefore, high temperature and high humidity without ventilation should be avoided. For Hanlan to grow well, ventilation plays an important role in the cultivation conditions. Ventilation can promote Hanlan's respiration, supply fresh and clean air, promote metabolism, photosynthesis, and increase nutrient production. Ventilation can also adjust the temperature and humidity of the greenhouse or shed, making it beneficial for Hanlan's growth. Ventilation can reduce the occurrence of diseases and pests, as most of them are caused by poor ventilation.
IV. Hanlan needs water
Like other plants, Hanlan cannot do without water. Hanlan is a mesophyte, and its roots do not require excessive water. The leaves require more water than other orchids, but how much water does it actually need? When and how to water? This is a question that beginners in orchid cultivation are eager to know, especially since its leaves are tall and large, and thinner than those of Moorchid. For Yifeng, the leaf shapes of Hanlan are diverse, possibly due to many hybrid varieties. Therefore, different approaches should be taken in cultivating Hanlan. Generally, Hanlan requires more water than other orchid species, especially during the growing season, growth conditions, and different pot materials and sizes. The amount of water should be adjusted accordingly. Beginners in orchid cultivation often overwater Hanlan when they see the leaves show signs of dehydration, fearing that the plant will dry out. This often results in root rot and death.
V. Some suggestions on using large pots for cultivating Hanlan
Using large pots to cultivate Hanlan is better, as Hanlan has larger and thinner leaves and requires higher humidity. Large pots can retain moisture better, and the potting soil can also evaporate to increase air humidity. Moreover, large pots provide more nutrients, which can meet the growth and development needs of Hanlan. If the nutrients in the growing medium are sufficient and the lighting is moderate, one plant can produce two strong seedlings, resulting in more and larger flowers. Large pots require less frequent watering, and using a 60 cm pot can go without watering for a whole year. Strong seedlings are less likely to get sick, reducing the need for medication and costs.
