The best time of year to renovate or overseed your lawn is late summer and early fall.  The soil is warm compared to spring which hastens germination and there is less competition from broadleaf weeds since most near the end of their growth cycle.  Summer heat and drought are past so it’s easier to maintain soil moisture.  Plus trees are losing leaves, which mean shady areas are more open.  We have Capital City Parks Grass Seed which is a premium mix of Bluegrass, creeping Red Fescue and turf-type perennial Ryegrass.  It thrives in full sun to light shade.  It is available at America's Best Flowers in 5 lb. and 20 lb. bags.  Also available is Woodland Shade which is formulated for light to dense shady lawns.  This grass seed mix has Fescue and perennial Ryegrass and is available in 20 lb. bags.
