A Denver Controller Still on May Minutes in August

A Front Range clock that still runs May runtimes in late August is starving south turf. We rewrite the program after we confirm the heads still throw.

May minutes do not match August heat on the Front Range

We still open Denver controllers in late August that never left the May start-up program. Cool-season turf that looked fine after blowout-startup will brown on a south strip when the clock still thinks it is spring. This is not establishment watering from a new install. It is last season's minutes left on a working system. Seasonal adjust only helps if the base times were honest.

NationScapes rewrites this on maintenance checks and maintenance programs. Watering-day rules still apply. Adding illegal days is not the fix.


Hardware faults still beat a schedule edit

Photograph every program, start time, and watering day. Then run the south zone. If heads are buried, misting, or blocked by a hedge, fix that first. A dry zone from pressure or a mature hedge is the August 21 article. A leak at a planted-over valve box is August 28. Do not hide those behind a longer runtime.

Homes in Centennial and Arvada do not share the same sun load. Repair work sits on sprinkler repairs. Fall blowout should inherit the summer map, not the forgotten May one.


What to send

Controller screenshots and a photo of the south strip that browned first. Call 303-934-9130 or contact us. More notes sit on the blog.

Move a Denver controller off May minutes before August heat finishes the lawn. The clock has to match the month you are actually in.
