It is relevant to remember though that the varieties of grass seeds are being continuously developed, and adjust to the present weather conditions better.

Tips on Keeping the Grass Seeds to Its Full Shelf Life
Naturally, grass seeds have specific shelf life which you can find on its packaging. Though, you can shorten its life expectancy if you are not following or observing certain steps to make sure that your seeds will last according to its shelf life.

Like perennial ryegrass, grass seeds may last long up to 5 years if they’re stored in an ideal environmental condition, according to experts.
When you say ideal or appropriate environmental condition should be cool, dark, and free of immoderate humidity like areas that are air-conditioned.
Depending on the variety, there are other grasses that usually can last up to 3 years in storage.
Though, you must be reminded that the germination chances are still lessen within the storage period.
When you are using stored grass seeds, you may require more seeds to lay an area than seeding fresh grass seeds.
The reason behind this procedure is due to the percentage of failure to sprout over time.
Grass Seeds Quality and Moisture
By nature, grass seeds swap moisture with the surrounding air that starts during their initial growth.
Just like what has been mentioned above, unopened bags of grass seeds will last longer if they were harvested in ideal dry conditions.
With dry air environment, the grass seeds in the field will not absorb as much as moisture or humidity as they enter storage.
Therefore, the fungal and rot problems are reduced as their usefulness increases.
The damaged grass seeds that are kept will not have the same usefulness of the healthy seeds.
Damaged seeds have cracks and broken marks that can let moisture to enter its inner part as bacteria.
Thus, it rots the grass seeds eventually.
Essentials between Sealed and Bagged Grass Seeds
The grass seeds that are sealed into a package will not swap moisture with the environmental air.
There is no new moisture that can enter into the sealed package except for the thirteen percent internal moisture level that’s already in within their container.
Hence, the humidity level is kept at a lower level, which further increases the usability of the grass seeds over the years of their shelf life.
In contrast, the bagged grass seeds incline to have some air swap with outside surrounding.
When there’s a hope or a leak inside your storage room or space, it creates a humid atmosphere.
Although, the seeds will only get small and slow effects through the small leaks of the unopened bags, but still, their ability to sprout can be lessened.
Additional Tips to Prolong Shelf Life of the Grass Seeds
To encourage the longevity of the grass seeds, the storage area should have a consistent air flow alongside with dry and cool conditions.
Vents with protective netting permit air to circulate past the unopened bags of grass seeds to lessen any buildup of moisture.
In addition, it also stops any form of pests to enter through the vent itself.
It is also ideal to spread out the bags of grass seeds, so they are not damaged as they piled up on top of one another.
Condensed grass seeds formed heat which contributes to high moisture or humidity and decreased their usability.
How did you find the information above? Are they helpful and viable? Were you able to follow them correctly? Grass seeds are living organisms that have limited life expectancy, and that they can be shortened when they are not properly handled and stored.
