Trees, grasses and other plants that are advertised heavily to grow well in any part of the country are usually things to avoid. Grassology is the one being mentioned the most these days. It appears to be a rebranded mix of Pearl’s Premium and because of the fescue and Kentucky bluegrass mix in the product, if you live anywhere in the South where summer temperatures are high, this won't work as anything but a so-so cool season fall over-seeding mix for some green in the winter. Also, there is no seed mix list provided on the Grassology website, so you don’t even know exactly what you’re planting. You could purchase a better quality mix specifically tailored to your climate at your local nursery or feed store.
