And The Good Brown Earth by Kathy Henderson (2008)

Gram and Joe love to spend time together taking care of the vegetable patch, but it takes a lot of patience. There’s digging time, planting time, weeding time, watering time, even thinking time. Meanwhile, the seasons change, and while Gram does things her way, Joe does things his way. But come harvest, each will find wondrous surprises, thanks to the benevolence of the good brown earth.
