Lawn Care Tips for Allegheny County
Acidic Soil Amendment
Your county's average soil pH is 5.1, 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.
Transition Zone Flexibility
Zone 6b is the transition zone — you can grow both cool- and warm-season grasses. Tall fescue is the safest cool-season bet; Zoysia is the most reliable warm-season option.
