Winter in Louisville is a short gray-gold season: lawns go dormant tan, a thin frost settles into the low spots overnight, and it is gone by nine in the morning. Rollin's Landscape Co., Inc. keeps working straight through it — leaf and debris cleanup, edges kept defined, walks and drives blown clean, and the mowing picking back up the moment the grass stirs in March. Dormant does not have to mean unkempt; a yard held tidy all winter greens up looking like somebody has been paying attention to it. That is most of the trade, honestly, and it is the part worth doing carefully. Louisville, Avera, Matthews, Stapleton and Wadley are all within reach.
