Kentucky bluegrass grows on a wide variety of soils, but thrives on well-drained loams or clay loams rich in humus. It also thrives on soils derived from limestone. It is somewhat exacting in its chemical fertility requirements, needing large amounts of nitrogen during active growth stages. Optimal soil pH is between 5.8 and 8.2. |
