84 Things You Should Know About How Long Does Grass Seed Stay Good In The Bag | Will Old Grass Seed Germinate

• 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
• Even if the germination rate is 50% or less, you can compensate by sprinkling more seed. You might want to keep older grass seed for overseeding projects , where it’s not a disaster if some seeds don’t sprout. Talk to a landscaping company near you for help overseeding your lawn. - Source: Internet
• Grass seed often has an expiration date stamped on the bag and can go bad over time, so it’s best to throw away any unused grass seed that is past its date. As grass seed ages the percentage of seeds that will be able to germinate decreases, forcing you to use more seed than normal to get adequate coverage. You may also spend hours irrigating, feeding, and nurturing seeds that will never produce grass. - Source: Internet
• Can grass seed go bad? The short answer is yes. If you spot excess moisture, mildew, or fungi, toss the seed. But, if you’re not sure, test the grass seed before you get rid of it. - Source: Internet
• It’s always important to give your grass seed the best possible start in life, but the old seeds may require extra diligence. Be sure to water your seed twice a day to keep the top inch of soil moist until the seed germinates. Once germination occurs, water every day. When your grass reaches about 3 inches in height, begin mowing as you normally would. You can resume your normal watering schedule after you have mowed your new grass once or twice. - Source: Internet
• Similarly, when it comes to lawn seeds, an important consideration for storage is where you live. This determines how cold it might get during the winters. If you see that the temperatures fall below freezing point, we recommend that you avoid the garden sheds, as it wouldn’t be the best idea. - Source: Internet
• The eye test method: Before Planting, carefully examine the seeds. Check the seeds for any discoloration or signs of fungi. Make sure the seeds do not have a strange odor. - Source: Internet
• Our small bags are polythene with air holes. Add a quite a few more if you’re going to store for a period of time. This can be done with a large pin or sowing needle. - Source: Internet
• It helps to check the viability of old seeds before using them in your new lawn or bare spots on your lawn. If you’re using seeds that have gone bad, you’ll be setting up your lawn for failure. The two popular methods of checking seed viability are described below. - Source: Internet
• Make sure your seeds don’t dry out and avoid covering the seed with straw as it may harbor unwanted weeds. Instead, cover the seeds with a thin layer of lawns soil. Though fresher is always better when it comes to planting seeds, properly stored grass seed can be viable for 2 to 3 years. Some varieties, like ryegrass, will last even longer. - Source: Internet
• That said, sometimes, the moment you look at the seeds, it becomes clear that you should not sow them on your lawn. Check the grass seeds you have stored, and inspect them well for any signs of discoloration or fungi. You can also look for the clumpy and damp areas of the seeds. - Source: Internet
• Now that we know grass seeds might expire, the question is, how long can one store them. The rule of thumb notes that grass seeds can be stored for around two to three years. But, seeds that are less than a year old have the best chance of germinating. - 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
• It is possible for grass seed to get too old to use. If stored properly in dry conditions and out of sunlight for more than a year, the germination rate will decrease, but slowly, and usually only 10% each year. The seed can still be used, but you will have to use more seed. In other words, purchasing older seed at a discount is not necessarily a good value! For best results, use fresh grass seed from Jonathan Green. - Source: Internet
• The best way to store grass seeds is in a tightly sealed plastic bag or container where they won’t absorb excess moisture. They are best stored indoors, and if the space allows, refrigerating the grass seeds may lengthen their viability. If your grass seeds have been stored in very good conditions, you can expect them to last for up to five years. - Source: Internet
• We suggest that you be sure that the seeds don’t happen to dry out. Try not to cover them with straw either, since it might contain unwanted weeds and seeds. Instead, we suggest that you cover the seeds with a thin topsoil layer. As discussed, fresher seeds always have a better chance than older ones when it comes to germination and sprouting grass. - Source: Internet
• Saving grass seed from one year to the next isn’t usually recommended, but it’s possible as long as you have reasonable expectations for how that seed will perform the following season. Like all seeds, the viability of grasses’ decreases the longer seeds are kept. Older seed is much less vigorous and is ultimately less likely to germinate. For best results when reseeding a lawn, it is always best to use new, high quality grass seed. However, if you do have some unused seed left over at the end of the season that you would like to save for over-seeding or small lawn repairs in the spring, pay close attention to how you store it. - Source: Internet
• Moisture – Too much moisture negatively affects seed viability. Always store your seeds in an air-tight container or plastic bag so that they cannot absorb moisture. In general, the cooler and dryer the storage area is, the longer your seeds will remain viable. - Source: Internet
• More often than not, they are rough estimates, and the shelf life of the seeds depends on their quality and how well you’ve stored them. Now that you can’t fully rely on the expiry date, it leads to a bigger problem. By looking at the seeds, there aren’t usually any overt signs that will prove that they’ve expired. - Source: Internet
• The water test is straightforward and easy. Take a water container and put your old grass seeds in the water. Give seeds 15 minutes to sit in the container. Seeds that sink are good to go. On the other hand, seeds that float are dead and will not sprout when sown. - Source: Internet
• Water the area quite well, but don’t drown it with too much water. The cooler temperatures and the coming frost and snow will most likely moisten the ground without having to water it all the time. Make sure that the soil isn’t saturated and soggy as this condition will kill your grass seeds. - 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
• The lack of sunlight becomes a problem sometimes while growing grass. As you know, sunlight is essential for any vegetation and essentially for all life forms to flourish. Most types of grass usually need at least three hours of sunlight each day in order to germinate. - Source: Internet
• You must also be careful about when you’re planting the seeds. Say you plant them in the spring. If you’re too early, they’ll sit on top of the soil and won’t germinate. By the time the weather gets warmer, several seeds get damaged and might not even sprout. - Source: Internet
• Even after you follow all the steps correctly, you might still see that the grass doesn’t grow as well as you’d expect it to. While this can be frustrating, maybe there is nothing wrong with your seeds at all. There are other factors that might prevent the grass from growing. - Source: Internet

• This will most likely be your last mow for the season, so do make it count. Mow your lawn slightly lower than your usual height, about two inches from the ground. This will allow your dormant seeds to make contact with the soil instead of sitting on top of the grass blades. - Source: Internet
• During the winter, the soil cracks naturally as the frost opens it up. With dormant seeding, the grass seeds find themselves in better contact with the moist soil because it has time to make its way toward the ground. As the soil moistens with the thawing snow, the seeds get buried deeper and create better contact to help them grow. - Source: Internet
• Finally, you have to put the cup in a dry and sunny spot. Usually, you will see that the seeds will start to germinate in 10 to 14 days. Sometimes, it might take even less time. - 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
• Grass seeds for one are costly. You wouldn’t want your hard-earned money to go to waste. You should properly store grass seeds as they’ll come in handy when you want to replant areas with poor growth. - Source: Internet
• Expect any seed to deteriorate by between 10% and 30% a year. Kept well, seed may deteriorate by only 10% a year so can last for 5 years. Just increase the sowing rate by 10% for every year you’ve kept it. - Source: Internet
• Yes, grass seeds can go bad when they are frozen. At freezing temperatures, the moisture that seed cells need to survive gets crystallized, which results in cell death and eventually the end of the seed’s life. Avoid storing grass seeds below 32 degrees Fahrenheit. - 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
• Store in a cool, dry place: Seeds are prone to heat. Extreme heat will damage the seeds and inhibit growth, thereby preventing it from germinating. This makes keeping your seeds in your garden shed a bad idea. Depending on the overall weather in an area, it is advisable to store your seeds in your basement. - Source: Internet
• Our 5kg and 10kg bags are made of polypropylene which is a breathable plastic. Do not put this in a bin bag or other container that does not breath. Seed contains moisture and will sweat in warm temperatures rotting the seed very quickly. - 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
• 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
• Just like any plant that needs to germinate, grass seeds also need watering in order for them to grow. When repairing or patching bald patches in the lawn, watering is one of the most tedious parts of seeding. With dormant seeding, the grass seeds make better contact with the moist soil as the snow melts. - Source: Internet
• We may find grass seed bags in our sheds, but they aren’t the ideal storage area. You want to avoid any place that the seeds may freeze. Unless your garage or shed is heated, you don’t want to keep the bags there. You may want to consider your basement or cellar, as long as they are dry. Another easy area is your refrigerator if you have space, so long as it is kept between 40 and 50 degrees Fahrenheit. - Source: Internet

• If you’re unsure of what a high-quality seed entails, we’ve got you covered. It will have less than 0.5% weeds, and there won’t be noxious seeds. There won’t be more than 2% of other crops, and filler materials, like dirt or chaff, will also be in lesser quantities than 2%. - Source: Internet
• To find out if your older seeds are still capable of germinating, get a Styrofoam coffee cup, put a paper towel in it, add one inch of water, sprinkle the grass seed on top of the paper toweling, put it in a warm, sunny window, check it every few days and water if necessary so it does not dry out. Put a plastic bag on top of the cup to create a mini greenhouse. The seed should germinate in the cup after 10 to 14 days. - Source: Internet
• Most seed packages include three, four, five or more different cultivars that come from different areas of the Pacific Northwest of the U.S. and Canada. They are checked for germination and purity and very often double-checked by the governmental agencies in the state where they are sold. We take every precaution to ensure that Jonathan Green Black Beauty® grass seed will germinate. - Source: Internet
• Depending on the species of your grass seeds, an internal seed moisture level of about 10 to 20% is needed for them to survive and germinate properly.

But, the mesh keeps the insects out, protecting the seeds from damage. - Source: Internet
• Storing in a cool dark area of a basement or garage are probably the best places though basements can be humid. Away from light is easy so the main aim then is to keep the grass seed dry and cool. Garden sheds get very hot and this can easily ruin your seed. If you have an old fridge and not much seed to store this would be perfect. - 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
• 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

• 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
• Water is essential for the growth of plants and vegetation. Seeds need water to germinate, but too much of a good thing can turn out to be problematic too. If seeds get more water than needed, it actually hinders growth. - Source: Internet
• So let’s look at the absolute ideal scenario. An unopened bag of grass seed that’s kept in ideal storage conditions can last up to 5 years. In comparison, an open bag usually lasts around 18 months according to an Oregon State University study. Grass seeds that grow in hardiness zones 3–9 can last up to 5 years if it’s grown in the absolute best conditions. Common grass verities on the other hand can last up to 3 years in storage. - Source: Internet
• If you know you’ll be storing at least some of the grass seed you buy, buying well is the first step to proper storage.
