When To Plant Fescue Grass. Fall is the best time to plant fescue and other cool season grass. Planting in the Fall presents the least risk of planting failure for cool season grass. Plant your cool season grass seed when the fall temperatures reach 75&deg and are dropping as winter approaches.
When to fertilize depends on if your lawn is made up of cool season grass or warm season grass. Cool season grasses (tall and fine fescues, Kentucky bluegrass, perennial ryegrass) look best when the weather is cooler: fall, winter and spring.In times of hot, dry weather they can go dormant.arm season grasses should be fertilized from the time of green up in spring through September, with supplemental winter feeding if overseeded with a cool season grass. But wait -- you've seen lawn services fertilize cool season lawns in summer.
