oss, specifically silvery-thread moss (Bryum argenteum), has become an increasing problem on bentgrass putting greens. With lower mowing heights and possibly lower fertility
making the turf less competitive, common moss is suddenly a weed problem. The dense stands that moss develops on a bentgrass green are virtually impenetrable to bentgrass growth.
