1. Know your grass. There are cool-season and warm-season grasses, and several varieties in each category. Cool-season grasses (Kentucky bluegrass, fescue, perennial ryegrass) are better suited for cooler climates, are most productive in spring and fall, sometimes take more irrigation and are generally mowed higher than warm-season grasses due to their erect growth habit.Warm-season grasses (Bermuda, St. Augustine, big bluestem) grow best in warmer climates, are typically more drought tolerant and are often mowed at lower heights.Be sure to check with your local lawn experts for specific recommendations for turf grass in your area.
