There are two types of electron microscope, the Scanning Electron Microscope [SEM] and the Transmission Electron Microscope [TEM]. Scanning Electron Microscope shows the external and whole image of a specimen such as a dust mite, or a nit. The Transmission Electron Microscope is literally the opposite.
Combat Extremeâ¢ Southern Zone - is a 3-way mixture of turf type fescue and Hybrid Bluegrass which is heat and drought tolerant enough to be used in USDA Zones 8 - 10 (partial shade recommend for USDA Zone 9 and 10). This mixture is approximately 90% turf type fescue grass seed and 10% hybrid bluegrass seed by weight. By seed count, this makes almost a 50/50 blend of fescue and hybrid drought tolerant bluegrass.
Fescue overseeding in shade areas each year will keep your fescue thick and healthy. All fescue areas should be overseeded each fall, because in Tulsa we're in a transition zone that is really too hot for fescue. Fescue will grow in full sun in climates farther north, but here we plant it in the shade. Each summer, our 100Â° plus weather will kill out a lot of our fescue. Fescue also needs sunlight. When we seed it in the fall, the leaves are falling off the trees and the temperatures are cool.
