To successfully seed and fertilize your lawn, prep the soil, apply seed first, and then lay down a starter fertilizer. Avoid high-nitrogen weed-and-feed products initially, as they can burn delicate new seedlings.
Fertilizing and overseeding at the same time can weaken germination because young sprouts are highly sensitive to nutrients. Seeds and existing grass compete for the same nutrients if fertilizer is applied too early, reducing the effectiveness of both processes.
It's up to you, but we recommend applying seed first, followed by fertilizer. Before you apply any lawn care product, start with your spreader settings. Different types of grass seed and fertilizer require different spreader settings for optimal coverage.
When it's October, people often wonder if it is too late to plant new seed. The good news is if you hurry, seed can still be planted in October with the hope that it will survive the upcoming winter. Although September is the best time, often we can still plant grass seed up to October 15 with good results.
Yes, you can spread grass seed directly on an existing lawn, but for lasting results, you'll need to prepare the area first. Mowing your lawn shorter, raking away debris, and lightly raking in the seed helps it reach the soil surface.
The best month to plant grass seed is September for cool-season grasses (like Fescue and Kentucky Bluegrass) and May for warm-season grasses (like Bermuda and Zoysia). Planting during these times allows the seed to take root while soil temperatures are warm and air temperatures are mild.
A 50 lb bag of grass seed covers between 5,000 and 50,000 square feet, depending on the grass type and whether you are planting a new lawn or overseeding an existing one. Seed size and weight greatly impact how far it spreads.
Grass seed typically takes 7 to 21 days to sprout in the fall, depending on the grass species and soil temperature. Slower cool-season grasses, like Kentucky bluegrass, may take up to 30 days. It will take an additional 4 to 6 weeks from planting before the grass is long enough to mow.
Even if you're a first-time lawn grower, you can seed right and avoid these common mistakes: Planting the wrong type of seed. Skipping the soil test and recommendations. Using lime incorrectly or unnecessarily. Ignoring recommended seeding rates.
Yes, you should fertilize after overseeding, but the timing depends on the type of fertilizer used. Applying a phosphorus-rich starter fertilizer right at the time of seeding gives new grass the best start. However, standard lawn fertilizers should be delayed to prevent established grass from choking out seedlings.
Troubleshooting and Common Mistakes
Skipping aeration, leaving seeds with little chance to reach the soil. Using the wrong type of grass seed for your climate and lawn conditions. Mowing too soon after overseeding, which can pull up tender seedlings before they are established.
Urea fertilizer is the most important nitrogenous fertilizer. There are two main reasons for urea fertilizer to be the king of fertilizers. Firstly, it has high nitrogen content about 46 percent. Secondly, it is a white crystalline organic chemical compound. It is neutral and can adapt to almost all the land.
Yes, 10-10-10 is a good fertilizer for new grass seed. Because it is a balanced blend, it provides the essential phosphorus needed to stimulate strong root development without forcing excess, weak leafy growth.
Proper Fertilization Steps for New Seed
Apply starter fertilizer only once you've lightly raked your soil and before you sow your grass seed. Once your grass has seeded, the next round should be a regular fertilizer application – this round should only occur four to eight weeks after the first, starter application.
After seeding and fertilizing: You'll want to keep the top inch of soil moist until the seeds start to germinate (aka sprout). This means misting the area once a day, maybe twice if it's unusually hot—but don't let the area get soggy or leave puddles of water.
Yes, fertilizer can burn new grass seed and tender young sprouts if applied incorrectly. Fertilizer burn occurs because the salts in the fertilizer draw moisture away from the seeds and fragile roots through osmosis, essentially dehydrating them.
Well, we've got great news: it's not too late! Seeding early in the fall is always best, but there is still time to develop a thicker, greener lawn if you seed now. It is always better to do so in the fall than waiting for next spring when weeds and cold weather can hinder your efforts.
“Poor Man's Fertilizer” is an expression to describe an early spring snow, and there's actual science behind it! “Snow and other forms of precipitation contain nutrients such as nitrogen and sulfur.
Timing: Apply fall lawn fertilizer once between August and November, right before winter hits, six to eight weeks after the summer feeding. Apply the Scotts® Lawn Care Program fall product now if you've been following that regimen.
Replanting seeds is illegal generally because of intellectual property laws and strict legal contracts. Companies protect their research and development investments by patenting unique plant varieties and genetically modified organisms (GMOs). When you buy these seeds, you agree not to save or replant them.
You should generally overseed your lawn every 1 to 3 years, depending on your grass type and how much wear and tear your yard endures. If your turf is dense and healthy, you can overseed every few years, but high-traffic lawns with bunching grasses (like fescue) often benefit from annual overseeding to stay thick.
In lawn care, the "150 Rule" is a helpful guide used to predict when a lawn will experience rapid growth or become highly susceptible to fungal diseases, depending on weather. The calculation and its two main applications depend on whether you are looking at temperature and humidity or high and low temperatures.
The best month to plant grass seed depends heavily on your region and grass type. Generally, September is the best month for cool-season grasses (like Fescue or Kentucky Bluegrass), while May or June is ideal for warm-season grasses (like Bermuda or Zoysia).
To tell if grass seed is germinating, watch for tiny, pale green "hair-like" shoots breaking through the soil, usually appearing within 7 to 21 days. Gently brushing your hand over the area reveals a fine carpet of seedlings that resist being rubbed away, unlike loose seed.
Grass seeds are remarkably resilient to cold, but vulnerable to extreme heat.
