If you are using a seed that has been in the ground for a long time, it may not germinate as well as it did when it was first planted.
This is due to the fact that the soil has had time to dry out and the seeds have not been exposed to as much sunlight as they would have if they had been planted in fresh soil.
If this is the case, you may want to try a different type of seed to see if it works better for you.

How do you know if grass seed is still good?
Put your seeds in a container of water for a water test. Allow them to sit for 15 minutes. If the seeds sink, they are still viable, but if they float, they will not grow.
How long does grass seed last when stored?
Grass seed should last between 10 and 18 months from the testing date, without a significant decrease in the rate of growth. The rate of growth will decrease each year after that, even though the seed can still be used. Grass seed is best stored in a cool, dry place away from direct sunlight.
How do you store unused grass seed?
The grass seed should be stored in a dry place. The stored seed should be checked periodically for rodents. Plant seedlings in the spring or early summer when the soil temperature is between 65 and 75 degrees F (18 to 22 degrees C). The soil should be moist but not soggy, with a pH of between 6.5 and 7.0. Seedlings should not be allowed to dry out before planting, as this can cause root rot and other problems.
If the seedling is planted too early or too late, it may not have enough time to develop roots and develop a strong root system before it needs to be pruned back to a smaller size. Pruning can be done at any time during the growing season, but it is best to do it in late summer or fall before the seeds begin to germinate.
Does grass seed get old and not germinate?
It is possible for grass seed to get too old to use. If stored 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. You will need to store the seed in a dry place away from sunlight for at least a year before planting it.
If you have a seed that has been stored for a long period of time, you may be able to tell if it is ready to be planted by looking at it under a microscope. This is because the seed is covered with a thin layer of white powder, which is a sign that it has started to sprout. You can also look at the seeds under the microscope to see if they have sprouted.
How long does grass seed last in an open bag?
If you roll it up and seal it as much as you can, it will last two to three years. Expired grass seed is usually only 10% more effective than fresh seed. If you don’t have a roll-up bag, you can use a plastic bag with a hole cut in it.
This will allow you to roll up the seed and store it in a cool, dry place for up to a year. You can also use an airtight container, such as a glass jar, to store your seed for a longer period of time.
Can you just throw grass seed on your lawn?
While it’s possible to simply sow the new grass seed over your existing lawn, taking the time to prepare your lawn ahead of time will increase the likelihood of seed germination and increase your chances of success.
Do good seeds float or sink in water?
The water test can be used to check for seed viability. Put the seeds in a container of water. If the seeds sink, they are still viable; if they float, they will not grow. Another method is to soak the seedlings in water for a few hours. The seeds should float to the surface, but they should not be completely submerged.
Seedlings that are soaked for long periods of time are more likely to die than those that were not soaked at all. You can also check the germination rate of your seeds by placing them on a piece of paper towel and letting them sit in the sun for 10 minutes or so. This will give you an idea of how long it will take for them to grow.
