As a local member of the community, I have been in the construction industry for just over 10 years. With experience ranging from general construction needs, to light electrical, and plumbing I have the knowledge it takes to complete a job on time and with excellent quality. \n\nWhy pay more for a large contractor to provide you a simple service when you can save money and have some peace of mind knowing a local member of the community is taking care of your needs and providing exactly what you need.

Lawn Irrigation questions, answered by experts

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. 

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.

Unfortunately, garages are one of the worst places to store grass seeds, despite their proximity to yards. Garages are hot and humid, two environmental traits that are detrimental to grass seeds. Grass seed has the best chance of survival in a dry space with temperatures ranging from 30 to 60 degrees Fahrenheit. 

With that in mind, the best place to store seeds is in a sealed container in the refrigerator or in the coolest part of your home. Also, limit your seeds’ access to sunlight for the best germination results down the line. 

Both zoysia grass and bermuda grass are somewhat similar to St. Augustine because they’re all warm-season grasses. Beyond that, most grass types have unique properties that set them apart. Zoysia grass costs twice the price of St. Augustine grass on average and it has thinner blades and a deeper green appearance. Bermuda grass, compared to St. Augustine, has much thinner blades, is softer to the touch, and has a higher tolerance for colder weather.

Not only are lawn depressions unsightly, they also cause your yard to be uneven and have divots, which can be a tripping hazard. Lawn depressions also make mowing more difficult and can potentially cause damage to your mower.

Aerating a lawn before seeding it or adding new grass seed is a smart decision. By loosening up compact soil and allowing it to take in more air and water, your seeds will have an easier time establishing roots and growing. Aerating beforehand also means your seeds will have better contact with the soil, so more of your seeds have a chance to germinate. If you do plan to aerate your lawn before seeding, aerate about two days before you plan to start seeding.
