Not All Grass Seed Is Created Equally By Jim Hole

Many people believe all lawn grasses are created equally. Nothing could be further from the truth.


For example, many packages of lawn grass seeds come as a mixture of different species and varieties. Two types of grass seed that dominate these blends are perennial ryegrass and Kentucky bluegrass. Perennial ryegrass grows quickly, but is not particularly hardy; nor is it long lived on the prairies, but it germinates rapidly and emerges quickly from the soil. Kentucky bluegrass is the premium lawn grass for our region, but it is much slower to pop out of the soil.
Still, perennial ryegrass is good as a “nurse” grass to protect Kentucky bluegrass until it gets established. You just don’t want too much perennial ryegrass in a blend. Perennial ryegrass seeds are also much larger than Kentucky bluegrass seeds. In fact, a kilogram of perennial ryegrass contains about 500,000 seeds, whereas a kilogram of Kentucky bluegrass contains a whopping 3,000,000 seeds! Therefore, you can see that buying lawn seed strictly by weight is not a great strategy.
The bottom line is that a bit of perennial ryegrass is good for helping to protect your Kentucky bluegrass, but a lot of perennial ryegrass is a waste of money.
September is a great month for sowing lawn grass seeds, so choose your grass seed carefully! We recommend Manderley Seed. Find it here, at Hole's Greenhouses.
