Thank you very much for helping me rephrase it. I wonder if you could help me express the message Eliot wants to convey through his poem.

What do the dried tubers symbolize?
Thank you.

1) Eliot, however, prefers the winter because it lets men leave in peace forgetting the past. He associates the winter with warmth and cosiness though it feeds the land with dried tubers, symbol of spiritual sterility.
2) The poem is written in free verse. He uses alliteration, repetition of the sound "ing". Being a symbolist writer Eliot gives importance to the sound quality of words.

I believe "dried tubers" is referring to the plants' roots. I think the poet is imagining them to be dried up under the earth since they aren't producing any growth above the ground.
