Just moved to Florida from Alaska and fallen in love with that cloud-like purple flowering tree you see everywhere? Got spots on the orchids? Worms in the tomatoes? Scared of repotting? Need some advice on salt-tolerant landscaping? Or on native plants? Volunteers at the state's county extension service to the rescue. Master Gardeners have completed an intensive course of study and are available five days a week from 8 a.m. to 5 p.m. to answer your gardening and plant questions. It's a well-used service. The office in Palm Beach took more than 160,000 phone calls last year. But when you talk to one of the Master Gardeners, you never feel rushed. They treat you as though you are the only tragic plant killer in the world, and then they give you advice that just might be life-transforming.
