How does Elizabeth Barrett Browning use imagery in Sonnet XXIX?

The imagery of this sonnet is pastoral and full of budding nature. There is a rejuvenation of nature which drives the metaphor of the speakers anticipation of the return of her beloved, About thee, as wild vines, about a tree, Put out broad leaves...The speaker's beloved is strong and eternal. The speaker uses a lot of tree imagery for this, Renew thy presence; as a strong tree should, Rustle thy boughs and set thy trunk.
