Late May sends silver maple seeds spinning down onto every lawn in Bridgeport Charter Township, and the grass underneath them is growing faster than in any other week of the year. Sanders Lawn Care Service inc meets that surge with regular mowing, trimming and cleanup across the township's neighborhoods and drives. Valley rain tends to come in warm and sudden, which means a yard can slide from fine to shaggy between one visit and the next. Keeping the rhythm is the whole trick — cut at the right height, clean up after, come back before the lawn has to ask. By June the yards look settled, and they stay that way.
