How Does Night-blooming Jasmine Overwinter? Master These Care Methods for a Safe Winter
Night-blooming jasmine (Cestrum nocturnum) is a very beautiful flowering plant that blooms in summer and autumn, opening in the evening and releasing waves of strong, sweet fragrance. It is often cultivated for ornamental purposes and prefers a warm, humid environment with plenty of sunlight. So, how does night-blooming jasmine overwinter?
1. Control room temperature
In northern regions, move night-blooming jasmine into a well-ventilated indoor space before the Cold Dew solar term each year, placing it in a room with plenty of sunlight. Sunlight can bring warmth to the plant and prevent root freezing or frost damage. Keep the temperature between 8°C and 12°C. If the temperature drops below 5°C, the leaves will turn yellow and fall off until the plant dies. Be sure to provide proper ventilation, otherwise leaves may drop and roots may rot.
2. Water in moderation
In winter, night-blooming jasmine enters a semi-dormant state, absorbing and evaporating very little water, so watering should be restrained. Overwatering often causes root rot, yellowing leaves and even leaf drop and death. However, do not water too little either. Generally, water once when the potting soil becomes dry and hard, keeping the soil slightly moist.
3. Stop fertilizing
In northern winters, temperatures are low and jasmine enters a semi-dormant state in winter, so fertilizing should be stopped. Generally, stop fertilizing starting in October. Fertilizing would cause root burn and affect its growth.
4. Rotate the pot
Rotate the pot appropriately. If it faces the sun in one spot for a long time, the plant will grow crooked and lose its aesthetic appeal.
5. Prevent and control pests
In winter, indoor ventilation is poor, making mites and scale insects more likely to occur. To control mites, use 800-fold diluted Kangman 23 emulsifiable concentrate, 2000-fold diluted 73% propargite, etc. To control scale insects, use 600-800-fold diluted 40% dimethoate emulsifiable concentrate.
The fragrance of night-blooming jasmine can make patients with high blood pressure and heart disease feel dizzy, depressed and uncomfortable, causing symptoms such as chest tightness and difficulty breathing. Therefore, it should not be planted in the rooms of patients with high blood pressure and heart disease, and when grown it must be placed in a well-ventilated area.
