Curb appeal starts at the curb, and in Delhi Charter Township that means the strip of grass along the older streets near the heart of Holt, where the maples have grown tall enough to meet overhead.

Much of what makes a house look tended is only ever noticed once it goes missing. Late spring is the real test, when everything grows at once and a skipped week shows from the sidewalk. Staying ahead of that is the whole trade.
