answer:Well, I am not perfectly familiar with Fescue, but, yes, in general, seeding in the spring or fall is best. Fall preferably as it has all winter to grow and become established and, planting in hot weather risks the young grass getting mildew or fungus that will kill it off in large patches practically overnight. Just liberally spread your grass seed in all areas you want covered and it will spread accordingly. make sure you look for the right variety either sun or shade strains or an all around, both, combo. You might want to look at hydroseeding, not very expensive and the seed is sprayed out in a slurry of moisture holding compound. However, this method that I once used in May here in CA. did end up getting fungus from the warmer weather though the general procedure was great for even coverage and ease of watering while waiting on the seed to sprout. You must keep the seeded areas evenly watered several times a day to promote sprouting and the hydroseeding slurry holds water well to promote better sprouting results. www.youtube.com/watch?v=WNc15ombaHk
