1, temperature control
If Shuangkui wants to survive the winter smoothly, it is necessary to control the temperature of the growing environment. Double-petal sunflower can be maintained under outdoor light in winter in the south, and the outdoor temperature in winter in the north is too low, so it is recommended to move it indoors for maintenance. It is best to keep the room temperature above 0℃ to maintain its normal growth.
Step 2 Reduce water supply
In winter, double sunflower needs less water, so it needs less watering. When curing, water can be used according to the specific conditions of the soil to keep the soil dry as much as possible. In winter, when the temperature is low and the water is watered too much, the water is not easy to evaporate, which is easy to cause water accumulation and lead to the phenomenon of root retting. In addition, it is best to water at noon in winter to avoid frostbite caused by low water temperature.
Step 3: Proper lighting
Double-headed sunflowers like to grow in sunny environment. In order to survive the winter, it is suggested to keep in a sunny position and receive all-day irradiation to promote the good growth of sunflower. If the light is not enough, the leaves will turn yellow and dry, and the growth will be poor, which will not guarantee a smooth winter.
4, appropriate pruning
When breeding double-petal sunflower in winter, it should be pruned properly to avoid nutrient loss affecting growth. It is suggested that all failed flowers and yellow branches and leaves be pruned and destroyed. After pruning, clean up the surrounding soil to avoid breeding germs and affecting the health of the double-petal sun.
