Your Essential Guide to Buying the Best Fall Grass Seed
Planting grass seed in the fall is one of the best ways to get a thick, healthy lawn next year. The cooler air and warmer soil create perfect conditions for new grass to grow strong roots before winter hits. But choosing the right seed can be tricky. Use this guide to select the perfect mix for your yard.
Key Features to Look For in Fall Grass Seed
When you shop, check the bag carefully. Good grass seed will tell you exactly what you are getting.
1. Seed Varieties (The Mix)
- Kentucky Bluegrass: This creates a beautiful, dark green, dense lawn. It handles foot traffic well but takes longer to establish.
- Perennial Ryegrass: This sprouts very quickly, often in just one week. It’s great for quick coverage or mixing with slower seeds.
- Fescues (Fine and Tall): These grasses handle shade better than others. Tall Fescue is tough and deep-rooted, perfect for sunny, dry spots.
2. Germination Rate
This number shows how many seeds in the bag will actually sprout. Look for a germination rate of 85% or higher. A higher number means less waste and a thicker lawn faster.
3. Weed Seed Content
This must be very low. Good quality seed bags list the weed seed content as less than 0.50%. Never buy seed if this number is high, or you will grow more weeds than grass!
Important Materials and What They Mean
The ingredients list tells the story of the seed quality.
Seed Purity Percentage
This is the most important number after germination. Purity tells you the percentage of the bag that is actually the grass seed you want. Aim for 98% purity or higher. Low purity means you pay for filler dirt or other unwanted plant matter.
Inert Matter
This is the non-living stuff in the bag, like bits of hull or dirt. A low inert matter percentage (under 1%) means you are getting more value for your money.
Factors That Improve or Reduce Quality
Not all bags are created equal. Some simple checks can save you trouble later.
Climate Specific Blends
Good seed companies make blends for specific regions. If you live where it gets very cold, choose a ‘Northern Mix.’ If you have hot summers, pick a blend with more heat-tolerant Fescue. Using the right blend improves survival rates.
Date of Packaging
Always check the date on the bag. Grass seed loses its ability to sprout over time. Seed packaged within the last 12 months performs much better than old stock. Old seed reduces your quality immediately.
Coated Seeds (Optional Improvement)
Some seeds have a coating that holds moisture. This coating helps the seed sprout faster, especially in drying soil. This feature often improves the initial growing success.
User Experience and Use Cases
Think about what you need your lawn to do before you buy.
High Traffic Areas (Playgrounds, Dog Runs)
You need tough grass. Look for blends heavy in Kentucky Bluegrass or hard-wearing Tall Fescue. These seeds establish strong roots that resist wear and tear.
Shady Spots
Most grass struggles in deep shade. Choose a specific ‘Shade Mix’ that contains high amounts of Fine Fescues. These varieties tolerate lower light levels better.
Patching Existing Lawns
If you are only filling in bare spots, you need fast results. Use a ‘Quick Start’ or ‘Repair Mix’ that has a large percentage of Perennial Ryegrass. This gives you fast green-up while the slower seeds catch up.
Fall Grass Seed Buying FAQ
Q: When is the absolute best time to plant fall grass seed?
A: The best time is usually early to mid-September. This gives the grass about six weeks to grow deep roots before the first hard frost arrives.
Q: Should I buy a cheap bag of grass seed?
A: No. Cheaper bags often have low purity and high weed content. You will waste time and money watering seeds that never sprout or that grow weeds.
Q: Do I need to prepare the soil before seeding?
A: Yes, preparation is key. Rake the area lightly to loosen the top inch of soil. This helps the seed make good contact with the dirt.
Q: How deep should I plant the seed?
A: Grass seed needs light to grow. You should lightly cover the seeds, no deeper than 1/8 to 1/4 inch. Many people just spread the seed and gently rake it in or cover it with a thin layer of peat moss.
Q: How often should I water the new seed?
A: Keep the soil consistently moist, not soaking wet. Water lightly two to three times a day until you see sprouts. After sprouting, you can water less often but deeper.
Q: What if the bag doesn’t list the purity percentage?
A: Avoid that bag. Reputable sellers must legally list the purity and germination rates. If they hide this information, the quality is likely poor.
Q: Can I use fertilizer with my fall seed?
A: Yes. Use a starter fertilizer when you plant. Starter fertilizers have higher phosphorus, which helps brand new roots develop quickly.
Q: Will this seed survive the winter?
A: If you choose a cold-hardy mix (like those common in Northern regions) and the grass establishes a decent root system before the ground freezes, it will survive well.
Q: How long until I can mow the new grass?
A: Wait until the grass reaches about 3 to 4 inches tall. Set your mower blade high for the first cut to avoid stressing the young roots.
Q: Can I use this seed if I have clay soil?
A: Yes, but you must amend the soil. Mix in compost or peat moss before seeding. This improves drainage so the clay soil doesn’t suffocate the tiny seeds.
