What You Need to Know about Lawn Fertilizers
Read this before you purchase your next (or first) bag of lawn food.
Your Lawn Needs Multiple Feedings Throughout the Year
Just like you, your lawn needs regular helpings of nutritious food to stay strong and perform its best. Well-timed fertilizer applications not only feed your grass to help it grow thick and lush, but also give weeds less room to grow. Ideally, you should fertilize your lawn with the right Scotts® Turf Builder® lawn food for your grass type 4 times a year: in early spring, late spring, summer, and fall. Feedings should be spaced 6 to 8 weeks apart.
To save you time, you can choose products that conquer all of your lawn issues in one fell swoop. Choose a Scotts® Turf Builder® weed-and-feed formula, for example, if weeds are a problem in your lawn. If you have thin, weak grass, Scotts® Turf Builder® Thick’R Lawn™, a seed-and-feed product, can be applied easily with a spreader to thicken existing turf and fill in gaps with new grass, all while it fertilizes. The best way to conquer obvious bare patches in your lawn, though, is with a more targeted seed-and-feed product: Scotts® EZ Seed® Patch & Repair, which combines high-performance seed with absorbent growing material and continuous-release lawn food.
With any fertilizer, it’s important to read the entire label and follow all directions.
Not All Lawn Foods Are the Same
If you've shopped for lawn food, before you might have noticed some numbers on the label that look something like this: 32-0-4. Most people ignore it, but this code tells you a lot about the lawn food you're about to buy. The numbers stand for Nitrogen, Phosphorous, and Potassium (N-P-K) and they tell you the percentage of those ingredients in the product by weight. But what do these letters and numbers add up to for the look of your lawn?
The Roles of N, P, and K
Nitrogen greens up your lawn and helps it grow. Phosphorous stimulates root growth and helps seeds sprout. Potassium helps grass withstand stresses like disease and drought. That's why Scotts® Turf Builder® Starter® Food for New Grass contains Phosphorous; it helps new grass establish a good root system.
Not all "N's" Are the Same
Nitrogen is nitrogen, but where it comes from and how it gets on your lawn can make a big difference. That difference is all about how it's distributed and how quickly it's released. Bargain and low-cost lawn foods contain mostly fast-release nitrogen. So your lawn greens up for about 7-14 days, and then the green fades away -- a feast-then-famine situation. Scotts® lawn foods use a mix of fast- and slow-release nitrogen to help your lawn stay consistently green for 6-8 weeks.
How N, P, and K Are Mixed
If you look closely at most store-brand lawn foods, they look like little pebbles of different colors. That's because the N, P, and K are all separate. So, when you spread the product on the lawn, you don't get an even distribution. Most Scotts® Lawn Food products have Scotts® All-In-One Particle®. So you get an even distribution of nutrients every time you apply.
