Question

how hemlock tree are related to death and crow too​

Answer 1

Hemlock is a poisonous tree with white evergreen throughout the winter. The crow and the hemlock tree represent sorrow. The dust of snow that is shaken off the hemlock tree by the crow stands for joy that Frost experiences. He has, therefore, used an unconventional tree and bird in order to contrast them with joy in the form of snow. Both symbolise the dark, depressive, sorrowful and bitter side of nature.
