The poem itself is modelled as a plant growing from the seed. The first line states “It takes much time to kill a tree.” Then the process of growth of the tree is described. It is presumed that the tree has grown from its seed.
The seed develops the root. The root works its way through the rocks and stones of the soil. The trees grows slowly by feeding upon the earth’s crust absorbing years of sunlight, air and water. There is a fight during the development of the tree which is suggested in the poem. The survival of the tree, in spite of the efforts to kill it, is shown by the lines. “And from close to the ground”.
