April in Vinings arrives with dogwood and thunder. A storm rolls through the afternoon, the air washes clean, and by next morning the grass has jumped an inch. That is Lawn Barberz weather — mow, edge, trim tight around beds and posts, then clear the clippings off every hard surface before packing up. The smell of cut grass on a wet spring morning near the river is most of the reward; the crisp line left behind is the rest. Neighbors notice it before they can say why.
