Celebrate National Arbor Day
April 27 is National Arbor Day this year. The National Arbor Day Foundation can help you find out where celebrations are happening in your state. It also provides ideas on how to celebrate on your own or in your community and explores the many reasons that the day--and trees--are worth celebrating. You can also find out about the foundation's many programs, including Tree City USA, learn lots about trees, and vote for your favorite candidate for national tree.
USDA Plant Hardiness Zone Map
All gardeners need to know their winter hardiness zone, and the USDA Plant Hardiness Zone Map is a way to find out. The zones are based on average minimum winter temperatures, and the cold hardiness of many commonly grown plants, including trees, shrubs, and perennials, is measured according to this USDA system. Check out the map and the explanations of what the map can (and can't) tell you about your microclimate and what you can grow.
