Grass seed is needed to create a lawn.
Storing the grass seed is essential to don’t go bad and can be used for future projects.
Many factors can affect how long grass seed is usable.
Factors such as how old the seed is and how you store it will determine how long your grass will stay green.
With so many different types of seeds available to purchase, knowing when to use which type could also make or break your lawn.
Here we will discuss how long grass seed lasts and how to store it properly and how much should be used per square foot of ground area.
What is Grass Seed?
Grass seed is the name for several different grass species used as seeds for lawns, golf courses, and other ground coverings.
Grasses come in many varieties, but there are two main types: cool-season grasses and warm-season grasses.
Excellent Season Grass Seed typically grows best in cooler climates, while Warm Season Grass Seed will do better in warmer temperatures.
Some examples of these include Bluegrass, Rye Grass, Fescue, and Bermuda Grass.
The type you want to use depends on your geographic location and how much sun your yard gets each day since some varieties need more sunlight than others to thrive.
You can find out what type of grass seed is best for your area by contacting a local nursery or researching online.
Amount of Grass Seed Needed Per Square Foot
Grass seed will need to be purchased in quantity based on the number of square feet you plan to cover with your new lawn.
The exact number of pounds required depends on what type and quality of grass seed you use, but it can range anywhere from 15-30 pounds per 100 sq ft for typical varieties.
In general, more expensive varieties of grass seed will require less seed than inexpensive varieties.
For example, you would only need about 20 pounds of a high-quality turf mixture for every 100 sq ft that you cover with the new lawn.
When buying your seeds, be sure to ask how many square feet the bag can cover and consult this chart below before making your purchase.
A good rule of thumb is that you will need about 50 square feet of lawn per person to provide enough space for walking and playing.
Factors That Affect the Longevity of Grasses
Many factors affect the longevity of grasses.
The two most important ones are climate and moisture level.
If you live in a region with high humidity, your seed will likely be longer-lasting than if you live somewhere dryer (like Colorado).
And whether or not there is enough rain to water your lawn regularly will also dictate how long it lasts.
If you want to make sure your seeds last as long as possible, here’s what we recommend:
It would be best if you stored them in a place where they’re protected from heat, light, and excessive moisture.
That means picking an airtight container like Tupperware – either transparent or opaque plastic containers work just fine – so that they can’t absorb airborne pollutants over time while still being able to breathe.
For best results, you should store them in a dark and cool place.
Your garage or basement are all excellent options.
Another critical factor affecting the longevity of grass seed is moisture.
When storing seeds, you have to make sure they’re not exposed to any more heat or light than necessary – and that includes humidity levels in your own home.
Here’s what we recommend: place a few sheets of paper towel at the bottom of your container with a layer of lawn seed on top.
This will absorb excess moisture from inside while still allowing air to flow through.
It would be best to store them away from windows so that no outside water seeps in overtime.
Doing these things ensures that your new grass will grow strong for years after it’s planted.
Types of Grasses Available for Purchase and Their Pros/Cons
There are many different types of grass seeds available for purchase.
The most common type is Kentucky Bluegrass, which grows well in various climates and soil conditions.
Other popular varieties include Bermuda Grass, Buffalo Grass, Perennial Rye Grass, Creeping Bentgrass, Tall Fescue (fine-leaved), Rough Fescue (coarse-leaved).
Each one has its pros/cons as follows:
- When grown on clay soils with poor drainage or high pH levels, there are potential problems such as chlorosis from iron deficiency due to the water-conducting properties of clay;.
- Bermuda grass is a popular choice for use in lawns due to its drought tolerance and good qualities such as high salt tolerance, low maintenance requirements;.
- Tall fescue requires more irrigation than buffalo or zoysia, but it thrives under hot conditions.
Buffalo will grow well when the temperature cools down during fall and winter, while zoysiagrass needs warm temperatures all year round.
The best type of seed depends on what you’re looking for – do you want something that grows fast?
Does the area need to be hardy against extreme heat/cold weather?
Do you have animals grazing that might interfere with growing plants? There isn’t one “best” kind of seed, so make sure to research the options and find one that best suits your needs.
How to Store Grass Seed?
Grass seed should be stored in a cool, dry place.
It is essential to keep the seeds away from heat and moisture, or they will spoil.
This means that you shouldn’t store your grass seed near any heat source like an oven or furnace.
Too much humidity can also lead to mold growth and seed rot, making sure the storage area isn’t too humid either.
The best place for storing grass seed may be in an attic or basement where it will stay at a safe temperature of about 60°F (4°C) with very little humidity.
It would be best if you also made sure there are no large quantities of dirt piles.
This could block airflow, which would create hot pockets in the space and not allow the seed to breathe.
Additionally, it would be best to store the seeds on a flat surface in a container that is not too deep or large, so there’s plenty of airflows and can be reached quickly for rummaging when needed.
The best types of containers are metal tins with tight-fitting lids, such as old coffee cans.
These tin cans have enough room inside them without being too big, which means they won’t get buried in the dirt while stored away from light sources like windowsills and doors where people might often walk by and kick up dust or other debris into the air.
How Long Does Grass Seed Last?
Grass seed is an essential part of lawn care.
It provides the necessary food for the most common types of grass.
Grass seed is usually treated with various pesticides, herbicides, and fertilizers during the production process to ensure it will grow healthy and be pest-resistant.
Grass seed will last for about 2 to 3 years if stored in a cool, dry place.
If it’s not possible to keep your seed at such low temperature or high humidity, it is advised that you store them inside an airtight container like a baggie or sealed plastic canister.
The airtight container should be labeled with the date of purchase and the type of seed.
If you want to store it for more than two years, it is best to transfer the seed into a freezer-safe container.
Be mindful that grass seeds should not be stored in direct sunlight, as this will cause them to lose their ability to grow or sprout after being sown.
A few things that will destroy your fresh grass seed after being exposed include moisture (whether from rain, flooding, high humidity), extreme heat exposure, or freezing.
Even though grass seed is a sustainable, natural product that can last for years if stored correctly, it’s essential to know how long your grass seed will stay viable, so you don’t end up wasting money on an expired batch.
That’s why we recommend storing the seeds in a dark and dry place with low humidity levels, like the garage.
You should also make sure they’re sealed tightly after opening them.
