The Highline Canal draws a green thread through southeast Denver, and the neighborhoods strung along it grow lawns with real conviction when they are watered right. Infinity Lawns and Beyond LLC keeps those on schedule through the long evenings — mowing, edging, string trimming, hedge work, seasonal cleanups, and the aeration and overseeding that keep bluegrass honest in a semi-arid summer. In July the mowing happens early or late, because midday sun here does a fresh cut no favors at all. Feed it, cut it high, keep the edges sharp, and a Denver lawn will carry you clear into October. That is the whole secret, applied weekly.
