– Avoid areas with poor drainage, which can cause root rot.
– Grass needs at least 4 to 6 hours of direct sunlight daily.
Climate Suitability
Kentucky bluegrass prefers cooler temperatures, thriving in USDA zones 4 through 7. Its growth slows significantly in extreme heat, so additional care may be needed in warmer regions.
Maintenance Practices for Perennial Kentucky Bluegrass
Proper maintenance ensures its longevity and lush appearance. Here are key practices:
