Orchids are one of our common ornamental plants that can thrive in a warm environment. However, when the temperature drops in winter, can orchids survive the winter smoothly? This is a question of concern for many enthusiasts. This article will introduce some methods and techniques to help your orchids get through the cold winter.
I. Basic Knowledge of Orchids
Before discussing how to help orchids get through the winter, we first need to understand some basic knowledge. Orchids belong to the Orchidaceae family, prefer a warm and humid environment, and have relatively high requirements for light. Generally, they need 4-6 hours of sunlight to thrive.
II. Choosing the Right Orchid Varieties
Choosing the right orchid varieties is an important step for their survival in winter. Different varieties of orchids have different degrees of cold tolerance. For example, varieties such as Cymbidium and Begonia are more cold-resistant and can survive the winter. In contrast, tropical plants like Oncidium and Phalaenopsis need to be kept in a warm and humid environment to survive.
III. Providing Suitable Temperature and Humidity for Orchids
In winter, as the temperature drops, the requirements for temperature and humidity for orchids also change. To help orchids survive the cold winter, we need to provide them with suitable temperature and humidity. Maintaining a room temperature of around 15°C-20°C and keeping the air humid will help the orchids stay healthy.
IV. Controlling Water for Orchids
In winter, orchids need less water than in summer. Because the temperature is lower, the plant's metabolism slows down, and the amount of water it needs to consume also decreases. If too much water is given in winter, it will damage the orchids, or even lead to death. We need to control the water for the orchids, preventing waterlogging or letting them dry out.
V. Proper Fertilization
In winter, the growth rate of orchids slows down, so they do not need much nutritional supplementation. Applying fertilizer in an appropriate amount can promote plant growth, but excessive fertilization can cause the leaves of orchids to turn yellow or even die. It is recommended to use a milder organic fertilizer in winter and avoid using fertilizers with too high nitrogen content.
VI. Pay Attention to Indoor Ventilation
In winter, to maintain indoor air humidity, we need to pay attention to indoor ventilation. However, excessive ventilation can cause the indoor temperature to drop too low, damaging the orchids. We should pay attention to controlling the amount and frequency of ventilation to allow air circulation, but not make the room too cold.
VII. Avoid Sudden Temperature Changes
Avoiding sudden temperature changes is very important for the survival of orchids. For example, if you move an orchid from a warm indoor place to a cold windowsill, it is easy to damage it. When moving the location of orchids, you should try to avoid sudden temperature changes as much as possible.
VIII. Pay Attention to Pest and Disease Prevention
In winter, the growth rate of orchids slows down, making them susceptible to pests and diseases. Common pests and diseases include spider mites, powdery mildew, and leaf mold. Methods for preventing pests and diseases include regularly inspecting the plants, keeping them clean, promptly removing infected leaves, and using appropriate pesticides.
IX. Increase Light Intensity
In winter, the light intensity is lower, which will have a certain impact on the growth of orchids. We can increase the light intensity by extending the daylight hours or using artificial light sources to help the orchids stay healthy.
X. Pruning Appropriately
In winter, the growth rate of orchids slows down, and appropriate pruning can be done. Pruning can promote the growth of new buds and make the orchids grow stronger. However, it should be noted not to over-prune to avoid affecting the health of the plant.
XI. Keep the Environment Clean
Keeping the growing environment of orchids clean is also key to helping them get through the winter smoothly. In winter, dust and bacteria are easily generated, which will affect the growth of orchids. We should regularly clean up the dust around the plants and keep the indoors clean.
XII. Pay Attention to the Growth Period of Orchids
Different varieties of orchids have different growth periods. In winter, some varieties of orchids enter a dormant period. At this time, it is necessary to reduce the frequency of fertilization and watering to ensure the plant can overwinter quietly.
XIII. Avoid Indoor Dryness
In winter, the indoor air humidity is low, which can easily lead to damage to orchids. We can avoid this situation by increasing indoor humidity. For example, you can use a humidifier or place the plant on a water tray to allow it to absorb moisture.
XIV. Perform Proper Transplanting
In winter, proper transplanting can promote the growth of orchids. If the plant's roots have already filled the original pot, they need to be transplanted into a larger pot to provide more nutrients and space.
XV.
Winter is a relatively difficult season for orchids. However, as long as we master the above methods and techniques, we can help them get through the cold winter. On the basis of maintaining suitable temperature and humidity, controlling water and fertilization, and preventing pests and diseases, we can also help orchids get through the winter by increasing light intensity, pruning reasonably, and keeping the environment clean.
