Longevity flowers are afraid of cold, low -temperature resistance to 5 ° C, ground -planting root system is relatively developed, cold resistance is strong, and the cold resistance of potted planting is poor. Planting and breeding in the south can be smoothly overwinter outdoors. Potted planting needs to be insulated on the above plastic bag. When maintaining longevity flowers in winter, the amount of watering needs to be strictly controlled to ensure that the soil is in a slightly drying state. Before the winter, you need to apply 1 to 2 slow release fertilizers to supplement nutrients.
Longevity flowers are afraid of cold
Longevity flowers are afraid of cold, have poor cold resistance, minimum energy to 5 ° C to low temperature, if the ambient temperature is lower after winter, 5 ° C will cause frostbite the leaves. Generally, the cold resistance of plant plants is stronger than that of potted plants, because the root system will grow to the ground, and the root system of the potted plant can only be in the flower pot, and the flower pots can easily produce frostbite after winter.
The climate in the southern region is relatively mild. After the warm -up work, longevity flowers can overwinter outdoors, and after winter, you can put a layer of plastic bags above the flower pot. Give adequate light during the day, and then place it in the environment of the backwind to the sun to maintain the winter. If maintenance in the northern region, it needs to be transferred to warm indoor maintenance in time.
When maintaining longevity flowers in winter, the amount of watering is needed to strictly control the amount of watering, so as not to water too much. Seine stagnant water. And before watering, water should be placed in the sun for a period of time, and the water will be perfold after the water is approaching the room temperature to avoid frostbite.
The growth rate of longevity flowers in winter is slow, and it will enter a short dormant period, but it is necessary to give sufficient nutrients to maintain the normal growth of the plant. Due to the low temperature in winter, you can apply slow release fertilizer after 1 to 2 diluted dilution before the winter. Try not to fertilize as much as possible after the winter, otherwise the root system will be burned.
