Its flowering period is concentrated from July to October. By the end of October, its flowers were basically withered. After the flower is withered, it should be carefully maintained and treated.
(1) pruning after flowering: This is the most important step. It can not only avoid the waste of nutrients, but also be conducive to the later growth and the next year's flowering. First, cut off the flowers to prevent them from consuming nutrients. In addition, only about 20 cm to 30 cm is left on the ground. If the water supply is sufficient, then we can keep some more properly. Attention, leaves to leave a part, do not cut all
(2) reduce watering: when the flowers are withering, the temperature has slowly decreased, so the amount and times of watering should be reduced. In winter, the water content should be strictly controlled. We should also pay attention to the use of water, can use rice water, which contains more nutrients.
(3) normal fertilization: the fertilization should be carried out normally after the flower has just withered. You can buy a special nutrient solution, about once a week. You can also use compound fertilizer, which is rich in nutrients, but you don't need to apply it too many times, just once a month. Gradually into the winter, the need for nutrients will gradually become less, then fertilizer can also reduce the application.
(4) precautions: usually, you can not take care of the plants with flowers, but don't dig them out.
