82 Facts Does Grass Seed Have A Use By Date | How Long Will Grass Seed Last In The Ground

• The germination rate of grass seed decreases by 10% to 20% per year even if you keep the seed in the ideal storage conditions. For instance, if the new seed’s grass seed germination rate was 90% when you stored it, it will drop to around 80% in two years. It will keep decreasing with each additional year. - Source: Internet
• When stored properly, bagged grass seed can remain fully viable for one year after the test date stated on its label. The date is when the seeds’ germination rate was tested. That rate should be 80 to 95 percent, depending on the type of grass. The rate should remain valid through at least the first year of storage after the test date, unless the seed is kept improperly. Each additional year of storage after the first year reduces the germination rate by 10 to 20 percent. - Source: Internet
• Keep away from pests: Storage spaces should be adequately cleaned and pesticides applied before storage. Rodent holes and hideouts should also be closed. Pests can severely damage your stored seeds and make it difficult to germinate. - Source: Internet
• This market is serviced by a very small number of seedsmen that have nationwide distribution into these markets. These seedsmen maintain a germination test for most of their stock in distribution and commonly furnish updated labeling for their products that have been held over past the test date. Some of these seedsmen employ representatives to assist chain store retailers in maintaining the test dates and stocking. Products can be relabeled with a test sticker if the lot number is also printed on it. - Source: Internet
• Grass seeds last between 10-18 months from the testing date when stored under ideal conditions. Keep in mind that every seed is different, and results vary. With proper lawn care services and seasonal maintenance in Calgary, your grass seeds can sprout and help your garden thrive. - Source: Internet
• A container is usually recommended for long term storage as it will help keep your leftover grass seed last longer by keeping moisture and humidity out. But the container should not be enclosed or damp. It should be able to keep insects and rodents away. - Source: Internet
• Seed tags may list several lines under the Pure Seed heading. Varieties with the highest percentage are listed first. The total of all the percentages under this heading reveals what percentage of the bag’s contents are pure seed. - Source: Internet
• If most of the seeds have started to germinate then you can be fairly sure that the rest of the packet is ok. If only 1 or 2 have germinated then you might have a pretty low strike rate with the rest of the packet. You can still use it, you’ll just need to use more than you usually would. - Source: Internet
• Put your seed in a container of water and let sit for 15 minutes. If the seeds are viable, they will sink. Seeds that float will likely not sprout. - Source: Internet
• Germinating conditions. If you apply the grass seeds during the spring season, the cold and wet weather can hinder the germination process. The soil temperature needs to be consistent at 55 degrees, and the air temperature needs to reach at least 60 degrees Fahrenheit for grass seed to germinate. - Source: Internet
• If the seed is received by the dealer within the time frame permitted above, it may continue to be offered for sale in Michigan providing the test date is not more than 11 months old, exclusive of the month in which the seed was tested. The Michigan Seed Law specifies that a person may not sell seed if the labeled test date has expired. That makes it the dealer’s responsibility to make sure the test date is current. The dealer should check incoming shipments to assure that the seed has a current test at the time of receipt and is no more than 5 months old at that time. - Source: Internet
• Generally, seeds are preserved better in colder environments. Bear in mind that they should be kept above freezing temperature. If they freeze, they’ve to be kept at that temperature throughout their storage period. This is because of fluctuations in temperature which damages the seeds. - Source: Internet
• Everything comes with an expiration date these days, and that includes grass seed. Store bought packaged grass seeds to come with a tested date and a germination rate. The germination rate is the rate you can expect your seed to germinate within the first year post packaging. Usually, stores bought grass seeds to have an 80-90% germination rate. And then, the germinate rate will decrease 10-20% each subsequent year of storage. - Source: Internet
• Storing your grass seeds beyond the expiry dates may mean you’ll be left with useless seeds. The longer seeds are stored, the lower it’s germination rate. Meanwhile, the optimum storage period for most seeds is between 10-18 months. - Source: Internet

• 3. Pure Seed: Purity indicates the percentage by weight of each grass variety and kind named. The percentages reflect the quantity of pure grass seed versus other contents in the bag. - Source: Internet
• Grass seed, like any other plant seed, has a finite shelf life. Grass seed stored for more than one year gradually has fewer seeds that would sprout, or germinate, if planted. The shelf life of lawn grass seed depends mainly on the strength and health of the grass plants (Poaceae plant family) that produced the seed and how the seed was stored after it was harvested. - Source: Internet
• If you can’t finish an entire bag of your seeds in the same year, store them in a cloth sack or burlap bag for next season. This material will allow good airflow. Place an open consideration of baking soda next to it to eliminate any unwanted moisture. - Source: Internet
• With older seeds, you may not get the same result as fresh seeds, but you may still be able to germinate and plant the seed. In other words, if your fresh seed promises a 90 percent germination rate, that will probably drop to about 80 percent in year two, and the grass seed decreases another 10 percent the year thereafter. This will just mean you will need to use more seed. - Source: Internet
• Please check the test dates on your seed stock. The test date is your responsibility to maintain if you are the one selling the seed. Seed products with expired test dates should never be offered for sale. - Source: Internet
• Kinds are similar to apples versus oranges, while varieties are akin to Granny Smith versus Red Delicious. For example, Mallard Kentucky Bluegrass listed as the variety and kind lets you know you’re getting more than standard bluegrass. The Mallard variety identifies an award-winning, drought-tolerant grass developed through Pennington-affiliated research and breeding programs. - Source: Internet
• Storing grass seed in a breathable material like a burlap bag or bag with mesh air vents will reduce molding risk and allow a good air flow. However, it will put your grass seed at risk of exposure to moisture. For best results, placing an open baking soda near it will help minimize moisture. - Source: Internet
• Each year inspectors from the Michigan Department of Agriculture and Rural Development perform hundreds of inspections across the state. The purpose of these inspections is to assure that seed products for sale are labeled to comply with the provisions of the Michigan Seed Law. The most common violation encountered by inspectors each year is seed offered for sale with an expired test date. - Source: Internet

When seeds are not correctly stored, they’re attacked by pests. These pests feed on them and destroy it. - Source: Internet
• According to All Creatures Healthcare, “The reason that grass seeds can be dangerous for dogs (or even cats) is that they can easily penetrate their outer skin in multiple areas. If left untreated, this can be incredibly painful – in worst-case scenarios, the internal damage it may cause can even be fatal”. Therefore use this product with care. - Source: Internet
• Information on every seed tag is based on actual testing of the seed product. Every item of information equips you to choose the cleanest, purest, highest quality seed for your needs. Formats vary, but every seed tag provides the following: - Source: Internet
• Grass seed should be kept in a cool, dry place where air can circulate around it and the temperature will stay between 40 and 50 degrees Fahrenheit. The seed should not be stored in an unheated shed, garage or any other place where the temperature will drop below 32 F. Keep bags of grass seed off the floor and someplace where mice can’t get to them. A basement or cellar is a suitable storage place as long as it is dry. The seed also can be stored in a working refrigerator if an open box of baking soda or a commercial desiccant is placed in the appliance to remove moisture. - Source: Internet
• A hot, humid garage is, unfortunately, one of the worst places to store seed. Grass seed is best stored in a dry space, in temperatures ranging from 32ºF to 60ºF. If you have space, the absolute best way to store seed is in a sealed container in the refrigerator until you’re ready to use it. If you don’t have refrigeration space, keep your seed stored in a container and try to use it as soon as possible after purchase. - Source: Internet
• 10. Noxious Weeds: Noxious weeds are categorized by state and listed separately on the seed tag. Noxious weeds are regulated and may be restricted or prohibited from state to state. Seed tags note the name and the number of seeds found per pound during testing. This is different than the other items on the seed tag that are calculated by percentage of total package weight. - Source: Internet
• On bags weighing 15 pounds or less, seed tags are usually printed on the back of the bag, at the bottom. On larger bags, tags are sewed into the bag’s top seam. On jugs of seed, you’ll find the seed tag printed on the side panel. Understanding a seed tag isn’t very complicated once you learn what it provides. - Source: Internet
• High Humidity: Grass seeds are made in the absence of moisture or with a very minute amount of water. High humidity encourages the growth of fungi on the seeds damaging them in the process. The average moisture content in a bag of grass seed is 2%, this continues to increase over time as more moisture enters the container. - Source: Internet
• You can store grass seeds in the garage as long as it has relative humidity below 60% and temperature between 32 and 60 degrees Fahrenheit. Garages are usually colder during the winters. For this reason, it is better not to store leftover grass seeds in garages if the temperature is unregulated. - Source: Internet
• Along with dry and cool conditions, seeds last longer if there is a constant air flow through the storage area. Vents with protective mesh allow air to circulate past the unopened grass seed bags to reduce any moisture buildup, as well as deter pests from entering through the vent itself. It is also good practice to spread the bags out so they are not piled on top of one another – compacted seeds create heat that contributes to high humidity and reduced viability. - Source: Internet
• Choosing the best grass seed for your lawn projects can seem overwhelming when you’re faced with so many choices in local stores. Differences in packaging, products and applications can complicate even the simplest comparisons. The bag itself provides important information about the product, the technology behind it and the types of projects it suits best, such as patching and repairing or seeding new lawns. But labels aren’t the only way to determine the best investment for your time and money. Products also carry seed tags to tell you more about what’s inside the package. - Source: Internet
• Seed tag information underscores the value of superior grass seed, but it also determines how much seed you actually need. Seeding recommendations are based on what’s called Pure Live Seed (PLS). A product’s PLS reflects pure seed percentages and germination rates. Planting rates on Pennington Seed packaging take PLS into account, so package directions show the amount of seed you need based on tested germination rates, but not all seed packaging does. - Source: Internet
• 5. Germination Rate: For each pure seed variety and kind, the germination rate reflects the percentage that germinated under laboratory conditions during testing on the seed lot. This is the percentage you can expect to germinate and produce normal, healthy seedlings under optimal conditions. - Source: Internet
• 13. Test Date: This date indicates when the seed lot was tested for germination. Seed germination rates drop over time, even under optimal storage conditions. However, lots can be retested and “over-stickered” with a new seed tag if the germination rate meets the label guarantee. - Source: Internet
• According to Jonathan Green , grass seeds eventually grow too old to remain viable. Storing these seeds out of sunlight in a cool, dry area can encourage them to last in excess of a year or more. However, the viability and germination rate will slowly begin to decrease – typically about 10 percent per year. So purchasing older or outdated grass seeds doesn’t always mean you’ve gotten a good value for your money. - Source: Internet
• General purpose - for use on lawns that have a mix of everything going on. General-purpose grass seed mixes grow well in most soils and grow fairly quickly, especially in spring and autumn. They’re also the best option if your lawn gets both sun and shade during the day. - Source: Internet
• Grass seeds generally take 7 to 30 days to germinate. The speed of germination depends on several factors like air temperature, soil temperature, soil content, seed condition, seed type, etc. Planting new grass seed takes a lot of understanding and care. - Source: Internet
• As earlier stated, even new grass seeds do not have a 100% germination rate. This means you might have areas with reduced growth in need of replanting. Your properly stored grass seeds can be used in those areas. - Source: Internet
• Some seeds can last for several years, while others have a short life. When properly stored, the seed’s shelf life can be extended. Come springtime, you can do a couple of tests to check if your seeds are still viable. - Source: Internet
• 8. Inert Matter: Seed products can contain non-seed materials as a natural occurrence of cleaning and processing seed. Inert matter reflects the percentage of these materials, such as sand, soil, stem pieces and seed parts. In all-in-one products, such as Pennington One Step Complete, this percentage also includes the product’s beneficial mulch and fertilizer. Tags on these products provide a breakdown of these inert ingredients. - Source: Internet
• Labels and markers Instructions Read the guide thoroughly to learn how long it lasts. Check the “Best-by-date” to know when it expires. Make sure to store in an airtight container in a cool, dark place (pantry or fridge). Always check for signs of spoilage before using. Did you make this recipe?

• 4. Variety and Kind: Each line of pure seed lists the variety and kind of seed next to its purity percentage. Kinds of grass are general species, such as Tall Fescue, but varieties are grasses that exhibit distinct characteristics in areas such as performance or appearance that distinguish them from other grasses of the same kind. Knowing variety names can help you match your lawn’s specific needs. - Source: Internet
• 7. Other Crop Seed: Any seed that comprises 5% or less of the product by weight can go unnamed. Smaller seed amounts, other than pure seed and weed seed, are combined in this percentage. - Source: Internet
• High Temperature: Grass seeds are easily damaged by high temperature. Keeping grass seeds in areas with unusually hot temperature will lead to a quicker degeneration of the seeds. Heat affects the molecular structure of the seeds and inhibits growth. - Source: Internet
• Proper labeling: Seeds you intend to store should be appropriately labelled especially if you’ll be changing the bag. Labels like name of the seed, expiration date, date of testing (date when last germination rate was calculated). All these will help you keep track of your seeds and know when to use them. - Source: Internet
• Expired test date violations are most commonly noted in the lawn/turf market. Expired test dates are not encountered at traditional agricultural dealers with nearly the frequency as in the specialty area. Lawn/turf products are most commonly offered in large discount type mass merchandising chain stores, hardware chain stores, and similar retailers. - Source: Internet
• Over time, as grass seed is exposed to extremes in temperature, it will gradually lose its viability. It’s estimated that around 10-15% of the seed in a bag loses viability over the course of a year. Unused grass seed is a living thing in a dormant state (fascinating, right? You can read more about that here). But it can die of exposure and old age. Once this happens, the seed will no longer germinate or have the capacity to grow into anything. - Source: Internet
• If the seeds are stored in the refrigerator, do not open the storage container immediately after removing it from the fridge. Opening the container immediately after removing it from the refrigerator can cause the moisture to condense on the seeds. Keep the closed container aside for a few minutes and let its temperature drop to room temperature. - Source: Internet
• 14. Sell By Date: Each state allows seed to be sold for a fixed number of months after the initial testing or retesting. Allowances vary, and some states require tags carry “sell by” dates. Seed tags include these dates alongside state-specific listings. - Source: Internet
• A container is usually recommended for long term storage as it will help keep your leftover grass seed last longer by keeping moisture and humidity out. But the content should not be enclosed or damp. It should be able to keep insects and rodents away. - Source: Internet
• Put the damp paper towel with the seeds into a Ziploc bag. Put the bag in a warm area, such as your kitchen window or on top of your refrigerator. Wait 10 days to see if any seeds sprouted. If five or more seeds germinated, then the grass seed will work. - Source: Internet
• Properly storing grass seeds will ensure you get quality seeds to plant the next season or to replant bare areas. It is of utmost importance to know the best way to store your seeds. This will save you money and time nursing seeds that may never grow because they’re bad. - Source: Internet
• The short answer is yes; grass seeds can expire. Like most products, you will see a use-by date on the packaging. It’s also good to note that the older it gets, the less chance the seeds will germinate, especially if your pack isn’t stored correctly. So for best results, use fresh grass seeds. - Source: Internet
• The cotton wool method: Take a few seeds and wrap with damp cotton wool. Leave under the sunlight for some days. If it germinates, then most of the seeds must be good. - Source: Internet
• Fall is just around the corner, which means so is the best time to complete your lawn seeding project. You may have a bag of grass seed in your garage from last year. Is it still viable? You can check the bag for an expiration date, or you can read more about what you need to know about grass seed storage and some simple steps to determine if it’s still viable*: - Source: Internet
