Where can I get information on landscaping my garden?

The square is paved with large concrete slabs. It features an ice rink/reflecting pool at the south end, a peace garden in the middle, and "Three-Way Piece No. 2" ("The Archer") by Henry Moore at the north end in front of City Hall. An elevated concrete walkway runs along the perimeter and allows access to the podium roof of city hall; budget limitations, however, now require that the walkway be closed for much of the year. At the southwest corner of the square, on Queen Street, is Oscar Nemon's statue of Sir Winston Churchill.
