For most of us, fall is for college football (go Dawgs!), cool, crisp air in the mountains, and raking leaves that fall and seem to get everywhere. It is also a time of year when many people consider overseeding their lawns so they have a nice green carpet of grass all year long. Over the years, annual ryegrass has been used to overseed a lawn, but lately the trend has moved to perennial ryegrass because it generally has better turf qualities, handles insects and diseases better and it is easier to manage.
