How often should commercial turf be aerated?+
On heavy Front Range clay under commercial traffic, at least once a year, and twice on high-traffic sites. Compacted clay sheds water instead of absorbing it and keeps roots shallow — which means you water more, which compacts it further. Core aeration (pulling actual plugs, not spike aeration) breaks that cycle and is routinely the single highest-return thing you can do to a commercial lawn here.
What mowing height is right for Front Range commercial turf?+
Kentucky bluegrass wants to be held tall — around three inches. Tall turf shades its own root zone, keeps soil temperature and moisture where the plant wants them, and blocks the light weeds need to germinate. Scalping it short is the most common self-inflicted wound we see: it burns in July, it invites weeds, and it drives the water bill up. Mowing height costs nothing to change.
Do rock beds really need maintenance?+
Yes, and more than people budget for. Rock isn't a maintenance-free surface — it's a heat sink that collects wind-blown soil and organic fines between the stones, which is a very good seedbed for weeds. Weed fabric buys a few years and then fails, leaving weeds rooted through the fabric, which is harder to fix. Rock beds want fines cleaned out and aggressive early-season weed control before anything sets seed.
When should commercial turf be fertilized in Colorado?+
Fall is the most valuable feeding for cool-season turf here — that's when the plant does its root-building work, and a strong root system is what carries the turf through the following summer. Heavy nitrogen in midsummer pushes soft top growth exactly when the plant is heat-stressed and least able to support it, and soft growth is what disease and insects find first.
Should we just remove some of our turf?+
Probably some of it. Narrow medians, sliver strips, steep slopes, and the ground between a sidewalk and a wall are nonfunctional turf — nobody uses them, they're the hardest ground to irrigate efficiently, and per square foot per year they're the most expensive ground you own. That's the best xeric conversion candidate on your property, and many Colorado water providers offer commercial turf-replacement incentives. We'll mark up which turf is functional and which isn't, and the call is yours.
