Yardeners don a hat from Disney World, cut-off blue jeans and the tennis shoes they bought the year they graduated high school. Then there are the tools. Gardeners' have matching handles. Each tool has a special function-and a special spot in the wooden gardener's bench at the end of the day. Yardeners are more likely to be out digging with an old serving spoon from the kitchen.
Gardeners also have a master calendar for all their gardening tasks.
Yardeners, on the other hand, lapse into yardening mode quite spontaneously. I understood completely. That's yardening at its best. If you see people strolling their grounds or setting up tents for a garden party, they are probably gardeners. After all, God created them and they are green.
