If you're new to Salem — or new to owning a Willamette Valley home — the first question after buying a mower is always the same: how often does this thing actually need to run? The honest answer is it depends on the month, and getting the rhythm right is what separates a lawn that looks cared-for from one that looks stressed.

Here's the schedule we've been running for Salem-area homes for 19 years, adjusted for a typical Willamette Valley season.

March through mid-April: every 10–14 days

Growth is waking up, but the ground is still cold and often too wet to work on without damaging soil structure. Wait until you can walk on the grass without leaving footprints, then start with a mow every 10–14 days. Cut higher than you will in summer — 3 to 3.5 inches — to encourage root depth for the coming stretch.

Late April through June: weekly, no skips

This is the peak growth window in the Willamette Valley. The soil warms, the rain hasn't quite backed off, and grass will put on serious length in a week. This is the stretch where weekly mowing pays off — skip a week here and you'll be scalping when you catch up.

July and August: weekly to every 10 days, watch the height

Growth slows as the valley dries out. If your lawn is irrigated it'll still push through and want weekly service; if it's not, the growth rate drops fast and you can stretch to 10-day intervals. Raise the mow deck to 3.5 or 4 inches — a longer blade shades the soil, holds moisture, and outcompetes crabgrass.

September through mid-October: back to weekly

Second peak growth window. The soil is still warm, the rain is starting to return, and grass responds. This is also the window for core aeration and fall fertilization — probably the single most valuable thing you can do for a Salem lawn all year.

Late October through November: every 10–14 days, then a final low cut

Growth slows. Final mow of the year should be slightly lower than your normal height — 2.5 to 3 inches — to reduce the chance of matted, disease-prone grass under the wet winter. This is also fall leaf cleanup season; the mowing schedule usually rolls into leaf work.

December through February: leave it

Grass is dormant. Don't mow. If you must clean up something (post-storm debris, one late leaf drop), do it dry.

The above is a rough Salem schedule — actual mowing frequency depends on your specific lawn (irrigated or not, grass type, sun exposure, soil compaction). If you'd rather not manage it yourself, our weekly residential lawn maintenance route puts you on a fixed day-of-the-week schedule with the same crew every visit.
