How to Read a Grass Seed Label
If more is better, than a lot should be great! That seems to be the logic when buying grass seed. To get the best results when seeding this spring, it might help to understand a few of the basics. Let’s take a look at a typical seed label:
First of all, what do those names mean? They are usually proprietary varieties that were specifically bred for optimum results. With improvements in seed breeding and technology in the past 7-10 years, these new varieties are more disease and pest resistant. However, over half the lawns in North America are over 7 years old. Newer varieties have definite advantages.
How about germination? The second set of numbers is the germination rate of the seed. Like anything else there are different grades and qualities of grass seed. Watch out for this number. The higher the number the better. Why pay for seed that won’t grow.
What is “other crop seed?” The seed listed here is for the “off types” of seed that can detract from the quality of the lawn. These are usually fillers used in lower priced mixes. The lower the percentage, the better.
Why is there weed seed listed? If there is any weed seed present it is listed by percentage of weight. While you don’t want any weed seed, it is difficult and expensive to keep them out. Similarly avoid those listing obnoxious weeds.
What exactly is “inert matter?” Inert matter is just what it sounds like. This is substance in the box or bag that is not capable of growth. Usually it is filler added to take up space. The lower the percentage the better.
How much seed do you really need? In depends on your application. In full sun, figure about 4-5 lbs for 1000 (M) sq. ft for a new lawn and about 1.5 lbs/M for overseeding. In deep shade your numbers shuld be more like 3 lbs/M for a new lawn and 1.5 lbs/M for overseeding.
