Tree Planting Day is on 12th March. All the people are going to plant trees on that day. But do you know how to plant a tree? First, we should dig the soil. We should dig a big hole for the young tree. Second, we can put the young tree into the hole. Third, we can put the soil back into the hole. Fourth, water the tree. We should often water the young tree. The last thing is waiting, it'll take a long time for the tree to grow. We have to wait for it to grow.
