We conclude this season's Gardener of the Week feature with Tom Blanford, an employee for the National Education Association in Washington. When he moved into his rowhouse three years ago, he confronted a back yard of bare gravel surrounded by a chain-link fence. Today it is an Asian-inspired retreat from the noise and bustle of the city. You can read about his garden and see more pictures tomorrow at baltimoresun.com/gardener.
