Let the area dry out! Tall fescue is much more drought tolerant, and will survive a while without water…..poa will not! Try this when the weather is nice and hot, with no rain the forcast for a least a week. After everything is completely browned out, resume a normal water schedule. The Tall fescue will green back up nicely.
