Like our hometown, persimmons and pomegranates planted in the yard can't survive the winter. My mother planted a pomegranate, which went into the cellar in winter and came out in spring. It has been more than 20 years, and at its peak, more than 50 pomegranates were produced a year. However, the ability is getting bigger and bigger, and it is difficult to get into the cellar. I didn't go home for a year and did a lot of anti-freezing measures, but I finally froze to death. Apples and peach trees are girls in fruit trees, which have complicated management and many diseases and insect pests, so it is very troublesome to plant them. I planted them in our yard, but they all died after only two years outside the house. Walnuts bear fruit late. Grapes are good, but they must be layered with soil in winter, otherwise the branches will be frozen and will not bear fruit that year. Moreover, the yard is always piled with dirt in winter and spring, which is unclean and unsightly. Jujube and apricot are the most cultivated trees, which are barren-tolerant, easy to manage and have a long life. "Peach three, apricot four, pear five years, jujube tree will pay back the money that year." Jujube trees bear fruit early, and apricot trees have almost no pests except drilling insects. It is most suitable for cultivation in a yard with little space.
