1、 Number of blades

In the normal conservation environment, it grows about 6-8 leaves a year. The age can be judged according to the leaves, but this method is not very accurate, because some old leaves will fall down with the growth, which can only be a rough estimate. Because there are old leaves that will fall, some roots grow like the roots of Chinese cabbage. These roots are older, usually more than 5 years old. Generally, the roots are smooth, and the leaves are not updated many times, so they are younger

2、 Bulb length

The growth age is closely related to the length of the bulb. The older the growth age is, the longer the underlying bulb will be. This is a more accurate estimation method. It can be carried out at the same time when changing pots, so as to avoid damage to plants caused by unreasonable pulling out, and achieve the effect of killing two birds with one stone

3、 Growth situation

The growth of plants is also related to age. In addition to the factors of maintenance, if the growth is not good, it may be that the maintenance time is very long and the age is relatively old. If you are growing well, you are relatively young
