First Edit:

Growth

I miss the nothing days of my youth -- I like this phrasing, portraying "nothing" as a good thing
when our worry was a seed.
Our stomachs rubbed together like two mittens
dirty with the year’s first snow. -- "dirty" doesn't seem to fit here since there seems to be a purity to the "nothing" times
Our tears were rain in June;
puddles that would always dry up. -- I'd think of a more compelling way to say 'dry up.' There are so many more interesting verbs. At least, I don't think you need, "up."
Your silence was not yet a barren tree. -- I don't like the being verb of "was." It forces you to contort the sentence with "not yet," which reads awkwardly and necessitates more words than necessary. I'd try to re-state this line with a verb that contains more spark, more action. You could say something about the silence being bountiful, which would be a nice contrast and rephrase the sentence so you don't have to use the "not yet." You could do this by using the opposite of "barren" since it might be easier to find a dynamic verb in that construction.
But your colourful leaves would become -- why "would become" instead of just became?
words lost,
broken shade all-encompassing.
I miss the nothing days of our youth. -- I like how this "bookends" the main concept. After all the winding roads the poem has led us on, this brings us back to the theme. I also like that it's slightly different, accenting "our" instead of "my" to say much about how life has changed in very little space.

Lots to like here, imagery wise. But, I particularly like the contrast between the comfortable, pristine silence of the young years, like a new snow, and the strained/unsatisfying silence of later years. This is a "fruitful" concept.


Anyway, all the best to you in your writing.
