The goal is to water often enough to keep the seedbed moist but not saturated, until the plants can develop sufficient root systems to take advantage of deeper and less frequent watering. Soils that have not been mulched will tend to dry out quickly. Less irrigation will be needed if mulch was used. The quantity of water applied will be small and should be maintained for at least three weeks following planting. As the turfgrass matures, reduce irrigation to a maintenance level to promote a deep root system.
Most herbicides are somewhat toxic to newly germinated turfgrass plants.
Delay postemergence applications of a herbicide for weed control as long as possible after seeding. Follow recommendations found on pesticide labels closely as far as timing of application and planting. Diligent care of the young lawn during the first two or three months is important for its overall success. Solid sodding covers the entire seedbed with vegetation. Spot sodding, plugging, sprigging or stolonizing refer to the planting of pieces of sod or individual stems or underground runners called stolons or rhizomes.
