Forcing forsythia (revised)

An earlier draft can be found here. I'm interested in hearing from anyone who is unfamiliar with "forcing" flowering shrubs in the springtime. Is there confusion?

Forcing Forsythia

After so many years
I finally reply.

Barren seasons stretched
across all those snowy
New England winters,
hushed and swathed thick
in white and ice.
Our first words
flared fast
until I hardly remember
what cooled them.

Though I prune
short slips
carried in from the cold,
when I finally write you,
my words
are narrow gnarled stubs,
tight fists,
hardly budded.
Shuddering
after so much
raw rain.
