Does Grass Seed Go Bad? Factors Explaining Why

One of the most frequently asked questions about growing grass is the possibilities of grass seeds going bad? Or how long can you store the seeds without getting expired? What are some possible things we could do to extend its life? Some of us might find seeds lying around our house and asked ourselves if this can still be planted. This article will help you identify the good seeds from the bad ones.

Grass Seeds Going Bad

Grass seeds, if left for a certain period of time, will eventually go bad due to different environmental factors. The period of time depends on the kind of seed being stored. The method of storage can also affect the grass seeds’ possibility of going bad. If you are trying to avoid grass seeds from going bad you need to secure the container and the location of the seeds, also these few factors should always be considered when storing grass seeds.

Factors That Cause Grass Seeds To Turn Bad

Before we can tackle the different reasons why seeds go bad, we need to understand what Germination is. It is the process of a seed growing into a plant. It is the sprouting of a grass seed into a seedling. It can be thought as anything expanding into a greater being from a germ or a small being. It requires several factors happening in harmony with each other to be successful.

1. Water

Water is used to moisten the seeds for them to swell and break the coat of the seed. Imbibition is the process of the seed taking up water. The hydrolytic enzymes are activated when the seed imbibes water. They are responsible for breaking down the stored food resources and turning them into useful metabolic chemicals.

2. Oxygen

Oxygen is used for metabolising the seed into germination. The main source of the seed’s energy is called aerobic respiration until it grows its leaves. The seed can be oxygen-starved if it is buried deeply within the soil or if it is waterlogged.

3. Temperature

Temperature affects growing rate and cellular metabolism. Different grass seeds require a wide range of temperature to germinate. Most grass seeds temperature ranges are above 60F or 16-24C, while the others can germinate just above the freezing degree. Some also germinate by alternating warm and cool temperatures.

4. Light

Some of the grass seeds aren’t affected by light. But most will require the seed’s canopy to open in order for the sunlight to hit the seedling so that it can grow. Light is a physiological dormancy of a seed and it is triggered by the environment.

These are the requirements for a plant to germinate. If these requirements are not met the seed will not sprout and grow into a plant. It requires time and patience for a seed to germinate. It is best to have seeds which are less than a year old. That way, they have a greater chance of success.

Storage Of Grass Seeds

Keeping the bag in a cool and dry place that is free from humidity will help the seeds last longer. It is recommended to store seeds at a temperature below 60F and a humidity level of 60% or less. The best storage containers for the seeds are bags that have mesh air vents to allow airflow while preventing insects from making contact with the seeds.

Until How Long Can They Be Stored?

Generally, grass seeds can be stored for 2 to 4 years depending on the conditions. But for germinating and planting purposes it is best to use seeds that are less than a year old. Some seeds, like the seeds from a ryegrass, can survive up to 5 years compared to other types of grasses.

Grass seeds bought on a store or package has an expiration date stamp at the back of the package. It is best not to use the grass seeds that have passed the expiration date, but it is up to you to take your chances of germinating the expired seeds.

Things To Look Out For

  • When deciding to store the grass seeds, it is best to use a secure, airtight container to avoid insects and animals from eating up the seeds. Be sure to keep the container away from moist so that it will not cause the seeds to form into a mold.
  • Look out for changing temperatures. The irregular rise and fall of temperature will cause the seeds to eventually die. The best places to store the seeds are basements. Gardening shed are often experiencing different changes in temperature. Also keep it away from direct sunlight to prevent it from drying out.
  • Always make sure that the seeds being stored are properly labelled so that the next time you come across the container you will know what seeds are those. It is also advisable to input the expiration date of the grass seeds.

In Conclusion

Grass seeds and all other kinds of seeds will all eventually go bad. Our main goal is not to prevent it from happening but to prolong the life of the seeds. The factors of germination are the reason why the seeds are going bad. Factors such as water, light and temperature can greatly affect the seeds condition in the container. It is important to store grass seeds in a secure and airtight container to extend its life and for it to be used in the next seasons of planting.
