New gardeners will appreciate a month by month to-do list with advice on when to divide perennials and when to plant shrubs. The New Twelve Month Gardener – a West Coast Guide (Whitecap Books, $20.00) is a few years old now, and refers to the west coast of Canada, but is still quite useful for gardeners in Western Washington. Use the monthly “Garden Highlights” to plan a garden that has interest in all seasons. Each month features a few in-depth articles on topics like flowering trees and species tulips.
