The poem is about the gap between what we do and what we hope will happen. The speaker says that home is "a reckoning with my eyes," meaning that to live somewhere is to keep facing what you actually see, and to be judged by it. Then comes the odd, striking image of eyes that have "exed out / all the garden," as if the speaker has crossed it off a list, struck through a drawing, or simply stopped looking at it. The garden may be literal, torn out as part of a renovation, or it may stand for something in the speaker's life that has been given up on. The poem leaves that open.
The last lines carry the feeling. The eyes "still expect a change / in one night." There is a quiet, rueful humor in that: the speaker has wiped out what was there, yet hopes to wake up and find something new already in its place. The mood is wry, a little impatient, and slightly sad. It captures how hard it is to wait for renewal after something has been removed.
