1、 How tall

1. Proper watering: if you want it to grow tall, you should water it properly at ordinary times. Spring, summer and autumn are its peak growth seasons every year. At this time, the demand for water is relatively high. You should water it once every three or five days to make the plant absorb enough water. Also pay attention to water control in winter. Just water it once every half a month

2. Sufficient light: light is an indispensable condition for its growth. If you are in the environment of light for a long time, the plant will not grow tall, and even the leaves will turn yellow and grow spots. Therefore, in addition to the hot sun in summer, you can put it in the light and bask in the sun more

3. Suitable temperature: its cold resistance is not very high. It is suitable to grow at a temperature of about 20 degrees. If the temperature is lower than 5 degrees in winter, the plant is easy to be frostbitten, and the root will rot and hinder growth. Therefore, if you want it to grow higher, you must give it a suitable temperature and control the temperature in winter

4. Sufficient nutrients: if you want it to grow higher, you can't do without nutrients. In the peak growing season, thin liquid fertilizer should be applied twice a month, so that the nutrient is sufficient and the growth will naturally be more vigorous

2、 What about falling down after growing tall

If it is the lodging of a single plant, it is usually caused by the lack of nutrients. It should be treated as soon as possible. Pay attention to regular fertilization in the growing season, and this phenomenon can be avoided only if the nutrients are sufficient. If multiple plants of hupilan fall down after growing tall, it is usually caused by rotten roots. Take off the pot, trim the roots and plant again as soon as possible
