You’re staring at your yard, holding a bag of grass seed, wondering if you bought enough or if you're about to waste a bunch of money.
It's not rocket science, but it's not exactly simple math either. Getting this right means the difference between lush grass or patchy frustration.
Let’s clear this up with practical advice straight from lawn care pros, breaking down exactly how much seed you really need, and what happens if you mess it up.
How Much Seed per Square Foot?
When it comes to seeding your lawn, there’s a simple rule of thumb:
Tall Fescue needs about 4-5 pounds per 1,000 square feet.
So, if your yard is roughly 8,000 square feet, you should plan on around 40 pounds of seed at the higher application rate (5 pounds per 1,000 sq ft). This ensures thick, even coverage.
What Happens if You Don't Use Enough Seed?
If you skimp on seed, your lawn might start out looking promising but quickly become patchy. Thin areas invite weeds, making your job twice as hard later on. Remember, weeds thrive where grass is sparse.
If you're dealing with bare ground, professionals recommend not being shy about your seed usage. In fact, putting down slightly more seed is better than using too little.
Real-Life Example: A Practical Breakdown
Let’s walk through an actual situation from a recent lawn care discussion:
The homeowner had about 8,000 sq ft of lawn.
They spread around 75% of a 50-pound bag of Kentucky 31 Tall Fescue grass seed.
That means they used about 37-38 pounds, slightly less than recommended.
A fellow lawn care professional quickly pointed out that for a brand-new lawn, using the whole bag (50 pounds) would’ve been ideal. Heavy rain further complicated things, potentially washing some seed away.
Protecting Your Grass Seed Investment
Rain is both your friend and enemy when seeding. A moderate, steady rain helps seeds establish quickly.
But heavy downpours, like our homeowner faced, can wash seeds away or cause uneven growth.
To avoid this:
Cover your seed with peat moss or straw: It helps hold moisture and protects against washouts.
Water lightly but often: If heavy rain is in the forecast, pause your seeding. It’s better to wait a day than start over entirely.
Did You Use Too Much?
You might wonder, "Can you put down too much seed?" Yes, but it's harder to cause problems from over-seeding than under-seeding.
Going a bit heavy isn’t usually harmful, though too thick a layer can cause competition for resources, leading to uneven grass growth.
Keep your seed spread evenly. Consider using a broadcast spreader—this ensures consistent distribution and saves you from headaches down the road.

Checking Your Work
Wondering if you hit the mark? A good tip from seasoned pros:
Weigh the leftover seed.
If your original bag was 50 pounds and you aimed for 40 pounds, you should have about 10 pounds left. Adjust as needed, especially if areas look thin.
This quick check helps ensure you haven’t unintentionally skimped.
