Troubleshooting New Carpet Grass Sod

Planted carpet grass, slightly green, watered daily, getting drier. The expert notes two grasses called carpet grass: Axonopus (tropical, cushion) and Agrostis (creeping bentgrass). Likely Agrostis. Sod needs firm soil contact (roller). Water frequently, test rooting weekly. If rooted but browning, check for fungus: lines at edges = drying; circles = fungus.
