Across the UK this summer, bowling greens are being baked in the intense summer heat. Weeks of hot, dry weather have left surfaces bare, cracked, and rock-hard. For many clubs, the underlying soil has crossed into a more serious condition — hydrophobicity — where the soil physically repels water, a phenomenon known as Localised Dry Patch.
