abundant. Leaves start yellowing and roots/stolons darken, and
easily pull up. Large irregular shaped discolored areas. Cultural control: maintain pH at 5.5-6.0 Provide medium to high P and K; avoid liming Improve root zone drainage and core aerate to minimize compaction Avoid excessive overwatering, but infrequent, thorough irrigation as needed to maintain plant growth and vigor. Prevent thatch buildup Maintain adequate, but not high levels of sulfur Avoid high levels of liquid calcium/lime/gypsum that will raise pH above 6.0 or create Micro-layers near the crown region |
