Lawn Care Tips for Clatsop County
Acidic Soil Amendment
Your county's average soil pH is 4.5, which is on the acidic side. Most lawn grasses prefer pH 6.0–7.0. Apply lime in fall to raise pH gradually — retest in spring before seeding.
Summer Heat Management
In Zone 9a, summer heat stress is the biggest threat to new grass. Seed in late spring so roots establish before peak summer temperatures arrive.
