Why Is It Wrong to Shake Saplings?

When saplings are planted, first they five on the nutrients preserved within them to take root and sprout. Later, they absorb moisture and nutrients from the earth for their growth. A newly-planted sapling needs special care and shaking it may cause it to die. As it is young, its roots are tender and might be broken by the shaking. Broken roots will not absorb moisture it will wither. The withered sapling never take root again because it has used up its preserved nutrients. Therefore, we take care of saplings and not to shake them.
