How to care for hydroponic flowers in winter? Master these care tips

As soon as winter arrives, many plants begin to "hibernate." In fact, as long as some plants are well protected, they can still stay fresh and alive. Growing hydroponic plants in winter is a good choice. How do hydroponic plants get through the winter? How can we help our hydroponic flowers safely get through this winter?

How to care for hydroponic flowers in winter.

5°C is a temperature that the vast majority of plants can withstand, and plants will also enter a dormant period. There is heating supply in the north, so there is not much to worry about. In southern cities, indoor temperatures are also above 5°C, so the problem is not too serious.

But just in case, in winter you should still pay attention to doing a good job of keeping hydroponic plants warm. When caring for hydroponic plants in winter, the central idea is to keep them warm and moist. We asked Teacher Huang from hydroponic flower experiential training for advice. The specific methods are as follows:

1. Hydroponic plants should be placed in a wind-sheltered position as much as possible, avoiding direct northerly winds.

2. Increase light exposure. During the day, place them as much as possible in a spot indoors with ample sunlight or bright diffused light, such as a south-facing room or by a window. They should receive as much sunlight as possible, but avoid prolonged direct sunlight outdoors. Also avoid drafty spots by windows to prevent cold wind from causing frost damage. If the indoor temperature at night cannot reach 5°C, then a thicker transparent plastic bag must be used to cover the entire plant from top to bottom to keep it warm and moist. Two to three small holes should be made in the plastic bag to allow ventilation. This ensures the flowers smoothly get through the coldest period.

3. Control water and nutrients. In winter, due to low temperatures, most plants successively enter dormancy or semi-dormancy. At this time, metabolic activity is extremely slow, and very little water and nutrients are required. Therefore, in addition to lowering the water level to 1/3 of the root system, you must also stop using nutrient solution, otherwise root rot and leaf drop are very likely, and even the whole plant may die. (Unless your hydroponic plant is kept in an air-conditioned room where the temperature can remain above 15°C for a long time, in which case it can be cared for according to the normal care procedure.) When changing the water, you should also pay attention to the temperature difference of the water. Freshly drawn tap water should be left indoors or in sunlight for a day to let the chlorine escape, and can be used only after the water temperature is consistent with room temperature. If the water temperature differs from room temperature by more than 10°C, it is easy to damage the roots and cause leaf drop.

4. Increase humidity and prevent dust. In winter, indoor air is dry, especially in air-conditioned rooms. Dry air can easily cause the leaf tips or edges of flowers that like humid air to dry out or scorch. Therefore, during the winter, frequently spray the branches and leaves with clean water close to room temperature to increase air humidity. For foliage plants, you can also take one part beer, dilute it with 5 times water, and spray it on both the front and back of the plant leaves, about once every half a month. This can make the leaves richly green and glossy, and can also make the leaves thicker, improving their ornamental value.

It should be pointed out that plants are actually just like people. The temperature at which the human body feels comfortable is also suitable for plants. So please use your own feelings to experience how your plants feel.
