1. Cause

In fact, we don't know that this phenomenon actually has its own conditions, and it also needs a better surrounding environment. In the case of bamboo seedlings, the root at the base is relatively small, which makes its growth ability not high. At the beginning of its seedling stage, the whole leaf is complete, but when it grows up, the leaf also begins to increase. When the temperature and light conditions are suitable for its growth, the leaf will slowly become a carved state. After it grows for half a year or even a year, there will be holes in the leaves

In addition, in addition to very small plants, even after pruning plants that have grown for many years, the regenerated leaves also have obvious holes. So we know that it doesn't open its back because the light and temperature are not the conditions it needs, and the watering is not done well, and the plant doesn't get the nutrients it deserves

2. Settle

When the temperature is particularly high in summer or in the early autumn when the temperature is not relatively low, we should let it avoid too much sun and put it in a cool and ventilated environment. Moreover, if it is under relatively soft lighting conditions, we should let it contact the sun, so that it can not open its back normally due to insufficient or insufficient lighting

At the same time, when it needs to grow, we should provide it with the water it needs, and we should note that its requirements for water are relatively high at this time. So at ordinary times, we should make the soil in the basin contain some water, sprinkle some water on the leaves, or spray water on the ground to increase the humidity. Of course, this can also reduce the temperature and make the plants grow better

Fertilization is also needed. We can topdressing once a week or two weeks. Nitrogen fertilizer is mainly used. Because these points are more important, according to the above points, its back opening is a very natural process
