1： High temperature

When raising Pennisetum in winter, it always doesn't grow new leaves, and the old leaves still yell yellow. In fact, there is only one reason. The problem is too low. If we want Pennisetum to grow vigorously in winter, we should give it a high-temperature maintenance environment, such as heating room

2、 Multiple illumination

In addition to the high temperature, raising Pennisetum in winter requires more sun exposure if you want to make the plant flourish. The light in winter is warm and soft. It can be said that the stronger the light is, the longer the light is, the better the plant will grow

3、 Moist soil

If you want Coptis to grow well in winter, it is easier to cultivate it in soil than in water. Planting it in fertile soil is easier than using water and more nutrient solution. Keep the soil moist in winter. Touch the surface of the soil and water it in time

4、 Frequent fertilization

If you want to grow well, you must apply fertilizer. However, when applying fertilizer in winter, you must raise it in the heating room on the premise of high maintenance temperature. You can often pour some cake fertilizer water, peel water or fish water to supplement nutrients for the plant

5、 General ventilation

If you want to make Coptis grow vigorously, you need high temperature, watering and fertilization. However, if the doors and windows are closed in winter and the maintenance environment is not ventilated, it is easy to cause yellow leaves and rotten roots of plants, and even diseases and pests. Therefore, you should be ventilated frequently at noon when the temperature is high

6、 Reconditioning shear

After being raised for a long time, Pennisetum will bloom, which will consume a lot of nutrients of the plant. After flower failure, it is easy to have a large number of yellow leaves, and the plant growth will deteriorate without new leaves. At this time, you can shave your head and let Pennisetum grow again, and the branches and leaves will flourish soon
