June Lawn & Sprinkler Checkup for Northern Colorado

The short version: June is the month to catch watering problems before NoCo heat, wind, and fast grass growth turn a small issue into a brown patch. Start with irrigation coverage, keep mowing height steady, and fix the spots that dry out first.

Why this matters right now

If you live in Johnstown, Loveland, Berthoud, Greeley, Fort Collins, Windsor, Milliken, Timnath, Severance, Mead, Longmont, Evans, Firestone, Frederick, Eaton, or Ault, you already know the drill: spring gave way to fast-growing turf, and now the wind starts doing its thing. In Northern Colorado, the easiest way to lose a lawn is to assume every problem is just “needs more water.”

The better approach is simpler: look at the whole yard. Mowing, irrigation, and soil moisture work together. If one piece is off, the lawn shows it fast.

Quick answer: The best June tune-up is usually a mix of proper mowing height, a sprinkler check, and a few minutes watching how water lands in the yard. That’s what keeps the lawn green without wasting water.

1) Walk the lawn before the mower starts

Before you cut, take a slow lap around the yard. You’re looking for the things that don’t show up from the street: dry strips near the curb, soggy corners, sprinkler heads spraying the sidewalk, and turf that looks thin where the sun hits hardest. Those are the spots that usually need attention first.

2) Keep mowing high enough to protect the turf

When summer arrives, many lawns do better with a slightly taller cut. Taller grass shades the soil, helps roots stay cooler, and gives the yard a better shot at handling heat between waterings. It also makes it easier to spot irregular patches before they spread.

The biggest mistake is scalping the lawn because it looks “cleaner” for a day. In NoCo, that usually backfires. If the grass gets cut too short, the roots work harder, the soil dries faster, and weeds get more room to move in.

3) Don’t guess on irrigation

Competitors in Northern Colorado talk a lot about sprinkler repair and summer watering, but the real win is getting your system to water evenly. A dry stripe is usually a coverage issue, not just a “more minutes” issue. That can mean a clogged nozzle, low pressure, a bad head, or a zone that’s throwing water where it shouldn’t.

If one area keeps going dry while the rest looks fine, don’t just extend the whole schedule. Check the zone and watch it run. Sometimes a small adjustment solves the problem faster than a full watering overhaul.

4) Match the job to the service you actually need

Sometimes the issue is maintenance. Sometimes it’s a landscape fix. And sometimes it’s both. That’s why we like keeping things straightforward: if the lawn needs consistent care, stay ahead of it. If the irrigation system is off, fix the coverage. If the outdoor space needs more structure, talk about a patio, retaining wall, or other hardscaping that reduces the amount of trouble you’re fighting every week.

5) What to watch for over the next two weeks

After you make adjustments, don’t walk away and assume it’s handled. Give the lawn a couple of weeks and watch the same problem spots again. If the same dry patch returns, the fix may be more than a runtime adjustment. If the mower is leaving the grass stressed, the cut height may need to come up. If water keeps hitting the sidewalk, the zone needs correction.

This is where a local crew helps. A family-owned team that works in NoCo every week knows the difference between temporary stress and a problem that needs real attention.
