Canada Green Grass Seed
Canada Green Lawn Seed is composed of: 41.3% creeping red fescue 30.0% Kentucky bluegrass 25.0% annual ryegrass 2.7% inert matter 0.5% other crop seed 0.5% weed seed
This mix provides quick growth and green up, however would require reseeding each season because annual rye is exactly that, annual. It dies yearly. At 25% of the total, that's a lot of dead grass.
Also, bluegrass does not tolerate the heat of Maryland or the droughts. It gets disease and slowly dies out. Lastly, creeping red fescue tolerates some shade, but does not handle much "foot traffic", i.e. kids or dogs.
In Maryland, we recommend tall fescue for sunny areas and fine fescue for shadier ones. Full shade cannot sustain turf.
