How long can grass seed be stored and still germinate?

• <div><p>When stored under ideal conditions, grass seed lasts anywhere from 10 to 18 months from the testing date without any real decrease in the germination rate. You can still use the seeds after this timeframe, but the germination rates drop 10% to 20% each year. </p><p>If you’re just embarking on an overseeding project, using seeds that have been in storage for a few years isn’t too big of a deal. However, if you’re planning on redoing your entire landscape, your best bet for a healthy, luscious lawn is to use new seeds.</p></div>

Can you seed existing grass?

• <div><p>Adding seed to existing grass is often <a href="https://www.angi.com/articles/overseed-lawn-guide.htm">known as overseeding</a>, as opposed to reseeding. Reseeding refers to the process of filling in bare or dying patches of lawn—or in some cases, full lawns—whereas reseeding supports existing lawns to prevent thinning. Overseeding is an ideal annual lawn care practice for grass fighting drought, disease, weeds, or pest issues.</p></div>

When is the best time to plant?

• <div><p>The best time to plant is between spring and autumn. Springtime weather is typically mild and is when nurseries start to bloom. When the summer weather arrives and it’s hot out, it’s best to avoid planting bare-root plants, but you can still plant many in-container varieties. The first sign of fall is another great opportunity to plant biennials if you live in southern states, or a lovely vegetable garden up north.</p></div>

Q: Will grass germinate in the shade?

• <div><p>Shade-tolerant grass seed still needs between four and six hours of sun to germinate, and many types require a little extra care to thrive. However, it is possible to plant new grass seed in shaded areas when you choose the right variety.</p><p> </p></div>

Q: Will grass grow back after vinegar?

• <div><p>Grass will grow back after being sprayed with vinegar. If you&rsquo;re looking for an alternative to chemical herbicides, vinegar can help you manage weeds. Use a mixture of 1 gallon of white vinegar, 1 cup of salt, and 1 tablespoon of dish soap to spray on your grass. This will kill the grass at the surface while keeping the roots intact, so it&rsquo;ll eventually grow back. You&rsquo;ll need to use an herbicide or manually remove the whole root system to get rid of grass for good.</p></div>
