Green-up comes fast in Ringgold — one warm week in April and the Bermuda turns from straw to emerald nearly overnight. Groover's Lawn Care meets it with a sharp blade and a straight pass, laying mowing lines that hold their direction the whole way across a lawn. Trimming around trees and posts, edging the concrete, blowing the clippings off: the small steps are what let the big shape read. Spring here is generous and relentless in about equal measure. Keeping ahead of it is the whole art of the season.
