1、 Lack of moisture

In the humid environment, if the water is insufficient, the leaves are easy to roll. However, the plant has certain drought tolerance, and the watering should not be too much, so as not to affect the respiration of roots. It is usually necessary to replenish water in time after the soil is dry, and sufficient water should be poured every time. It can be kept wet in summer, and it is necessary to control the water properly after autumn, which can also have the effect of keeping out the cold

2、 The temperature is too low

Hupilan is a plant that is afraid of cold. The temperature should be controlled between 20-30 ℃ and not lower than 10 ℃ in winter, otherwise it will be frostbitten and cause the leaves to roll. In winter, you need to move the plant to a warm room, or put a bag on it to help the plant prevent cold and keep warm. It should be noted that although it is warm indoors in the north, do not put the plant too close to the heating, otherwise it will also cause water loss on the nearby side and affect its growth

3、 Soil hardening

Hupilan has lax requirements for soil, but it is easy to lead to soil hardening if the soil is not changed for a long time, which will affect the infiltration of water and the growth of roots, so as to roll the leaves. Loosen the soil regularly and change the basin every two years. When changing the basin, prepare new basin soil with garden soil and cinder to ensure that the soil is loose and has good air permeability

4、 Strong light

Hupilan prefers light, but is afraid of strong light. Once exposed to the sun, the leaves of the plant will roll. In summer, you need to put it in a semi shady place, or shade it to avoid being exposed to the sun. However, it should not be completely out of light, otherwise its leaves will also be dark and look lifeless. It is appropriate to provide bright scattered light
