Temperature: Cestrum nocturnum is produced in subtropical or warm temperate regions, and its cold resistance is relatively poor.Therefore, when the weather begins to get cold in the middle and late October, it needs to be moved into a warm room or greenhouse, and the temperature can not be lower than eight degrees.If the temperature drops below five degrees, its leaves will slowly turn yellow and the whole plant will die.
Illumination: Evening primrose likes sunny environment. Generally, from May to October, it can be maintained on a sunny balcony. In midsummer, it can be exposed to the hot sun.In other months, the demand for sunlight is much lower.
Watering: The growing period of the evening primrose is in summer. During this period, it is necessary to keep the potting soil moist and increase the frequency of watering appropriately, but be careful not to let water accumulate in the potting soil.
Fertilization: The flowering period of evening primrose is between May and October, so it is necessary to ensure that there is enough nutrient supply between May and October.The liquid fertilizer can be applied once every ten to fifteen days before April, and once every half month after late April.
Soil: The soil for planting cordate telosma should be loose and fertile, with good drainage and acidic soil. Before planting, some broken bricks can be filled at the bottom of the flowerpot, which is conducive to drainage.
Replacing pots: In order to keep the soil conditions of the pots suitable, it is necessary to replace the pots according to the growth of the plants.Repotting can be done in early April, when most of the old soil needs to be removed and some of the old roots cut off, and then replaced with a new culture.After repotting, the plant needs to be pruned to promote the germination of new branches, and pay attention to keeping the potting soil moist.
