The best tree planting season every year is spring, especially before and after the scare and something.

Spring, especially around Zhejiang and the vernal equinox, is the best planting season. In China, 1979 stipulates that March 12 every year is "Arbor Day", which is very reasonable.

The main purpose of cutting down trees is to grasp the opportunity of budding branches. Too early, its nutrients are still concentrated in the roots and trunk, not distributed to the branches, and the bud tip can not get nutrition and can not stand out.

If it is too late, the leaves have already grown out, and it is necessary to absorb a lot of water and nutrients from the roots, but the incision can not take root quickly and can not supply the leaves in time. Although some trees have been cut down and transplanted earlier, they are actually waiting for this appropriate opportunity.

Autumn is also a good season for planting trees. But there are some differences in nature between planting trees in autumn and planting trees in spring. In autumn, the vitality of trees is slow, and even slowly stops. When transplanting, even if the roots and branches are slightly damaged, it will not affect their internal physiological balance. When spring comes, it will grow back as quickly as transplanting in spring.

So planting trees in spring is the first opportunity to make full use of plant vitality, which is positive. Then, planting trees in autumn is to wait for this opportunity next spring, so that trees have more time to adapt to the new soil conditions.
