How to Read a Grass Seed Label

Just as the right blueprints lead to a sturdy, beautiful home, understanding your grass seed label can lead to a beautiful, green lawn that not only looks good, but is money well spent. In this guide, we’ll cover the different parts of a grass seed label, ensuring you’re well-equipped to make the best choice for your yard.

Seed Type

Using the right type of seed for your area can really make or break your yard. Make sure to consider things like your location, climate and any challenges your yard may face like heavy foot traffic or shade.

What does germination rate mean?

Term Defined

Germination Rate: The germination rate on a grass seed label refers to the percentage of seeds that are expected to sprout and grow into normal, healthy seedlings under the proper conditions.

The germination rate demonstrates the potential a seed selection has; it tells you the percentage of seeds expected to sprout into healthy grass. A higher rate means more seeds will grow, directly influencing the density and uniformity of your lawn’s growth.

For instance, our Lawnifi Santee Centipede Seed boasts an impressive 93% germination rate, ensuring swift and even lawn coverage.

Pro Tip: For most grass types, a germination rate of 90% or more is very good. Variations dependent upon seed variety.

The germination rate is more than just a number; it’s an indicator of value in your investment. Higher germination rates mean fewer seeds are required to achieve a lush lawn, making your purchase more cost-effective in the long run.

What does purity on a grass seed label mean?

Term Defined

Purity: The purity of grass seed on a label refers to the percentage by weight of the desired grass seed species in the seed mix, compared to other components like inert matter, weed seeds and other crop seeds.

When we talk about purity on a seed label, we’re not talking about the quality of the seed itself. It’s about how much of the seed mix within the package is actually the grass type you want. In other words, a high purity means you’re getting lots of the good grass and not much else.

For example, our Lawnifi Santee Centipede Seed has a purity of 49.06%, meaning that 50.94% of it is other inert matter that IS NOT seed.

At first glance, this may seem like a negative thing, with Lawnifi Santee Centipede Seed, the other 50% is a coating of fertilizer to help the seed germinate quickly and grow healthy. Be sure to read labels carefully to make sure you understand what might be taking up space in your grass seed.

In grass seed talk, a higher purity means a more consistent lawn. When your seed has high purity, your lawn will be filled with the same grass type, making for a uniform lawn. You won’t have to deal with random types of grass showing up, making it easier to take care of your lawn.

What is inert matter on a grass seed label?

Term Defined

Inert Matter: Inert matter is made up of things like seed shells, sand, mulch, little pieces of stem, dust and other things that come from cleaning the seeds. It’s the part of what’s in the seed bag that won’t grow into grass. Inert matter doesn’t have weed seeds or seeds from other plants—it’s just the stuff that isn’t seeds.

Inert matter might sound like unnecessary filler, but it can sometimes include beneficial substances like our special fertilizer coating designed to protect and nourish seeds. However, generally, you’ll want a lower percentage of inert matter to ensure you’re getting more seeds in your bag.

To get the most bang for your buck, opt for mixes with low and/or beneficial inert matter. This ensures you’re paying for seeds, not fillers, giving you more green for your green.

What is other crop seed?

Term Defined

Other Crop Seed: Other crop seed refers to seeds in the mix that aren’t the main grass type you’re buying. This can include different kinds of grass or even other plants like clover.

The “Other Crop Seed” section of the label tells you about non-target grass seeds in the mix. Lower percentages are preferable to ensure the purity of your lawn’s appearance and texture. Even a little bit of these other crop seeds can cause trouble because they might grow into plants you don’t want, competing with the grass you’re trying to grow.

The best scenario is to have almost no other crop seeds in the mix, because any amount can make the grass seed mix less pure.

Pro Tip: The seed label is required by law to list the percentage by weight of any “other crop” seed present, but only if that seed makes up 5% or more of the total.

What is weed seed?

Term Defined

Weed Seed: Weed seed refers to seeds from plants that you don’t want, like crabgrass, dandelions and plantain. These aren’t the grass types you’re trying to grow. They can sneak into the mix by accident when the seeds are being cleaned and processed.

Weed seed percentages on the label are critical; they indicate the likelihood of unwanted plants in your lawn. Opt for mixes with the lowest possible weed seed percentages to maintain a pristine lawn.

Our Lawnifi Bermudagrass Seed with 0.00% weed seed is an excellent example of how low weed seed percentages can lead to a beautiful, hassle-free lawn, saving you time and effort in garden maintenance.
