If you plant your own grass by seed, you may be left with leftover seeds. One solution is to simply spread the seeds throughout your yard, but this is a waste of seeds. The best thing to do with leftover seeds is to store them for later use. When you store seeds, you save money on the cost of seeds since you have to buy less the following year. As long as it is stored properly, grass seed can be saved for up to 10 months.
Put the grass seed in a cloth sack. Cloth is good for storing seeds, as it allows air to flow through, which in turn reduces the risk of mold growth. You can keep the seeds in the original packaging if it is still intact.
Store the seeds in a refrigerator. A cold, dry environment is best for storing seeds. If you do not have room in a refrigerator, store the seeds in the coolest, driest area of your house, such as a basement. Since basements are often damp, you should put a small, open box of baking soda in the seed bag to absorb excess moisture.
Plant the seeds within eight to 10 months. The longer the seeds sit, the less likely they are to germinate, so use them as soon as possible.
