Landscape Maintenance in Seattle: What It Really Takes to Keep a Yard Looking Good
Most homeowners don’t think much about landscape maintenance until something goes wrong. The Pacific Northwest makes maintenance both easier and harder than other regions. Easier because our mild climate supports year-round growth. Harder because things never truly go dormant — moss grows through winter, weeds germinate in January, and shrubs can put on two feet of growth before June.
This guide covers what professional landscape maintenance actually includes in the Seattle area, how to think about the DIY-vs.-hire-it-out decision, what different levels of service cost, and a month-by-month calendar for the tasks that keep a yard healthy across our unique climate.

Common Questions
Frequently Asked Questions About Landscape Maintenance
For a typical Eastside residential property, monthly maintenance runs $250-$500 depending on scope. Many homeowners find that a quarterly service ($400-$800 per visit) covers the big tasks while handling weekly mowing themselves. The math usually works out to $3,000-$6,000 per year for a mid-size Eastside property.
Early to mid-September is the sweet spot. Soil temperatures are still warm enough for germination, fall rains keep things moist, and cool weather favors fescue and ryegrass blends that do best here. Core aeration before overseeding is critical if your lawn gets regular foot traffic.
Yes, but less than you might think. Two to three applications per year is plenty. A fall application (September-October) is the most important feeding — it fuels root development through our mild winter. Avoid high-nitrogen quick-release fertilizers in winter.
It depends on the plant. Spring-flowering shrubs should be pruned right after they bloom. Summer-flowering shrubs get pruned in late winter. Evergreen hedges typically need two to three passes per year.
It depends on your property’s complexity. Mowing and basic weeding are manageable DIY. Where professional help pays for itself is in pruning, irrigation management, fertilization timing, and seasonal tasks requiring specialized equipment. Many clients handle weekly mowing and bring us in quarterly for skilled work.
