What problems should we pay attention to when planting flowers in winter?

Rizhao 1

Compared with the hot summer, the sunshine in autumn and winter is warm and soft. For some plants that naturally like to bask in the sun, such as copper grass, longevity flower, tiger thorn plum, etc., the sunshine time can be extended. For plants that don't like direct sunlight, such as evergreen, watercress green and cold water.

Flowers, arrows, etc. It can be properly irradiated through the window at the right time to avoid direct sunlight and prevent a large amount of evaporation and water loss after being exposed to the sun and wilting and dying.

2. Temperature and humidity

In autumn and winter, many people turn on air conditioning or heating at home. At this time, be careful not to put plants too close to the heating, nor to put them in the air outlet of the air conditioner. Long-term baking will cause the leaves of plants to dry up and die of dehydration. Plants that don't like heat, such as ivy, should

Through timely ventilation and other means, avoid the influence of excessive indoor temperature.

Step 3 change water

Hydroponics plants should also pay attention to reducing the frequency of changing water. Under natural conditions, the lower the water temperature, the higher the dissolved oxygen content in water. As the temperature decreases in autumn and winter, the content of dissolved oxygen in water will increase relatively, so compared with spring and summer, the frequency of changing water for hydroponic plants should be

Reduce appropriately. Small containers should be changed once every 7- 10 day, and large containers should be changed once every 3-4 weeks.

Extended data:

1, fertilization

Fertilization is very important for flowers and trees in winter, but not all flowers need fertilization. According to reports, fertilization should be stopped for balcony potted plants in dormancy and semi-dormancy. Clivia, calla lily, Pineapple, etc. 0.2% potassium dihydrogen phosphate and 0. 1% urea can be prepared.

Flower and tree liquid, such as white orchid, Milan, pomegranate, crape myrtle, jasmine, etc. , should continue to apply dilute phosphorus and potassium fertilizer; For most foliage plants, nitrogen fertilizer should be stopped and some low-concentration potassium fertilizer should be applied appropriately to increase the cold resistance of flowers.

2, the prevention and control of pests and diseases

At present, it is still a season with serious pests and diseases. Flowers and trees are vulnerable to pests, such as scale insects, red spiders, aphids and whiteflies. The diseases are leaf spot and branch rot. Therefore, flowers should clean the basin wall and bottom before winter, and cut off dead branches, pests and diseases.

In the first week after moving into the house from the balcony, it is best to open the window for ventilation, so that the potted flowers can gradually adapt to the temperature change, otherwise the leaves of the potted flowers will easily fall off. Generally, it should be placed in a sunny and warm place indoors. When placing, western potted plants should be placed in the front row, and shade-tolerant or semi-shade-tolerant potted plants should be placed in the middle and back row.
