How to spend the winter with evening primrose

Night incense is a very beautiful flower, blooming in summer and autumn, blooming in the evening, floating out of the nostrils and fragrance, often cultivated for viewing, sexual preference for warm, humid, sunny environment. So, how does nocturnal incense spend the winter?

1. Control room temperature

In the north, evening incense is moved into a ventilated room before the cold dew festival every year and placed in a sunny room, which can bring warmth to night incense and prevent it from freezing roots or frostbite. Keep the temperature between 8 ℃ and 12 ℃. If the temperature is lower than 5 ℃, the leaves will wither and fall off until death. Pay attention to proper ventilation, otherwise it is easy to cause leaf shedding and rotting roots.

Second, appropriate watering

In winter, evening incense has entered a semi-dormant state, the amount of water absorbed and evaporated is very small, watering should be controlled. If overwatering, it often causes rotten roots, leaves yellowing and death of fallen leaves. But watering can not be too little, it is generally seen that the basin soil is watered once when it is dry and hard, in order to keep the basin soil slightly moist.

III. Stop applying fertilizer

The temperature in northern China is low in winter, and jasmine is in a semi-dormant state in winter, so fertilization should be stopped. Fertilization is generally stopped in October. If fertilized, it will cause the plant to burn roots and affect its growth.

Fourth, turn the basin

If you turn the pot properly, if it is a place facing the sun for a long time, the plant will grow askew and affect its appearance.

V. Prevention and control of insect pests

Poor indoor ventilation in winter, prone to mites and shellfish. In order to control mites, we can use anti-mite 23 EC 800x solution, 73% mites 2000 times solution and so on. To control shell insects, 40% dimethoate emulsion 600-800 times can be used.

The aroma of nocturnal incense will make hypertension and heart disease patients feel dizzy, depressed and uncomfortable, causing chest tightness and breathing difficulties and other symptoms, therefore, it is not suitable to plant nocturnal incense in the room of hypertension and heart disease patients, and it must be placed in a ventilated place when breeding.
