Haven Landscaping - Seattle's Expert Landscapers

Bare patches are common here due to compacted soil, moss, or seasonal stress. The most effective fix isn't just throwing down seed. We first diagnose the underlying cause—often poor drainage or soil pH—then aerate, amend the soil, and overseed with a shade-tolerant, Pacific Northwest grass blend. This addresses the root issue for a thicker, more resilient lawn.

Absolutely. Mature trees are a treasure in Seattle, but their surface roots can create uneven, difficult-to-mow lawns. Instead of damaging the roots, we recommend creating a 'root zone' solution. This can involve carefully grading the area, adding a thin layer of topsoil mixed with compost, and planting a durable, low-maintenance ground cover like creeping thyme or dwarf periwinkle that thrives in rooty, shaded conditions.

The best windows are early fall (late September to October) and early spring (March to April). Fall is prime because the cooler temperatures and increased rainfall help new grass establish strong roots without the heat stress of summer. Spring is good for addressing winter damage. We can assess your lawn and schedule the work during these optimal seasons for the best results.
