What do buyers say? 82% of 29,000+ Amazon reviewers rated this product 4 stars or above.
Scotts Turf Builder Grass Seed Sun & Shade Mix thrives in scorching sunlight or densely shaded conditions, making it our top choice. This fine-bladed grass mix can even hold up in droughts and cold winters. It begins to grow in five to ten days; you can mow it after blades reach three inches in height. For optimum growth, water your lawn twice daily for three weeks.
Each individual seed, wrapped in a special WaterSmart Plus coating, absorbs twice the amount of water as its uncoated counterparts. The coating also protects your seedlings from various lawn diseases, and feeds them essential nutrients to jump-start growth. Although this mix tolerates extreme weather changes, Scott’s does not recommend using it in Southern states.

Scotts Turf Builder Grass Seed Sun & Shade Mix is the best grass seed overall. The seeds’ special coating makes them more absorbent, allowing your turf to thrive year-round in sun or shade. However, if you have pets or kids and want something that can grow with heavy foot traffic, Jonathan Green Black Beauty Heavy Traffic Premium Grass Seed Mixture might be a better choice.
What to Look For When Buying Grass Seed
One of the most important things to keep in mind when buying grass seed is the climate, as some blends do better in certain regions. For instance, Bermuda grass is native to the southern hemisphere, so it thrives in the South and the Southwestern United States.
That being said, some grass species (such as fescue and ryegrass) can grow in a variety of climates. Be sure to check the product description before purchasing grass seed to confirm it can grow where you live.
Another thing to consider is the level of sun exposure your seedlings get. Species such as Bermuda grass and some types of ryegrass need at least a few hours of sunlight a day to thrive, whereas fescue can grow in densely shaded areas.
Some mixes are formulated to grow in sun or shade, any time of year. Check the product information before buying grass seed to make sure it’s suitable for the amount of sunlight your yard gets.
If you’re in the market for low-maintenance grass seed, look for an option that contains fertilizer. That way, your seedlings have the nourishment they need to grow quickly and flourish. Some blends also contain mulch, which helps keep the soil healthy, retains water, and prevents weed growth.
Speaking of weed growth, you may consider grass seed that specifically indicates it’s a weed-free (or 99 percent weed-free) formula. Additionally, some seeds are individually coated with a special substance that makes them more absorbent, meaning you don’t need to water as often, and disease resistant.
The best time to plant grass seed depends on the type of seed and the climate. However, since most mixtures germinate when temperatures aren’t too hot or cold, planting in the fall for a cool-season grass and spring for a warm-season grass is typically ideal. Seedlings thrive in semi-warm soil, with moderate daytime temperatures and slightly cooler evenings.
To prepare the soil for grass seed, start by removing any sticks, large rocks, and weeds from the surface. Then, break up the soil with a spade, hoe, garden fork, or core aerator, continuing to remove rocks and debris as you go. If your grass seed lacks fertilizer, add a slow-release fertilizer to the soil before planting.
The goal is to keep the top layer of soil moist at all times, so water grass seed once or twice a day until it germinates. How much and how often depends on where you live and what the weather is like. When your seedlings reach about an inch tall, you can switch to watering every other day. After a few weeks, when the grass has established, weekly or bi-weekly watering should suffice.

When To Apply Weed and Feed-Complete Year Round Guide
As a Lowes garden manager, one of the most asked questions I get is about healthy, green, weed free lawns. Here are my tips and directions for your Lowes lawn care program applying Sta Green or Scotts.
Weed and feed fertilizer will help improve your lawn.
The number one question: When is the best time to apply weed and feed to my lawn?
Well…it depends really. Where you live, whether you have sun or shade, and lots of other things make a big difference in what your lawn needs. Most regions in the United States can apply weed and feed from March till November.
A well-fed lawn is healthier, which means it has a better root system to combat heat, cold, drought, mowing, foot traffic and other stresses.
One easy to follow rule is to use the summer holidays as your guide.
If you’re going to fertilize, remember the summer holidays of Memorial Day, July 4th and Labor Day as good times to apply.
Memorial Day-Weed and Feed
July 4th– Fertilizer with Insect Control
Labor Day– Fall Fertilizer
Remember, crabgrass control will need to be early spring, so maybe around Easter.
There are some simple rules to follow when choosing and applying your weed and feed products. Lowes can help you build a successful program specifically for your lawn with Scotts Turfbuilder and Sta-Green Fertilizer programs.
And while fertilizing even once a year will improve the condition of the lawn, a well-fed lawn that receives 4 feedings a year will do much better.
Weed and Feed Basics and the 4 Step Process
Ok, this is my disclaimer: This is my version of the 4 step program that I have used for years. It works! Make sure you always follow instructions on the bag and use the correct settings on your spreader.
You will find many different versions of weed and feed programs out there. They all will be some variation of the following:
Step 1. Crabgrass Preventer
Step 2. Weed and Feed
Step 3. Summer Fertilizer with Insect Control
Step 4. Fall or Winter Fertilizer
The #1 Mistake: Skipping Step 1 and not using a crabgrass preventer.
The best looking lawns don’t have crabgrass for a reason; they use a crabgrass preventer every year! You can skip it if you want, but I don’t recommend it. Most people don’t realize this, but Scotts Halts and Sta Green Crabgrass both have fertilizer as well in the bag. So take care of the crabgrass and get in that first application of fertilizer.
Your soil supplies some of the nutrients that grass needs but most soils are not able to provide all of them during the entire growing season. Fertilizer helps your lawn stay healthy by promoting new blade and root growth and will aid in recovery from summer foot traffic and pest damage.
Weed & feed is the generic name for a broad range of lawn chemical products designed to strengthen existing grass and kill off certain weeds. It generally improves your lawn’s ability to absorb water and food, and adds necessary nutrients which promote healthy growth. A healthy lawn discourages weed growth and enables a strong root system for your lawn.
The “weed” portion of weed and feed is one of a variety of broad leaf-targeted herbicides, usually Dicamba or 2,4-D, that attacks dandelions, dollarweed, and most other green leafy weeds. The chemical is applied to and absorbed by the leaves of the weed.
The granules will not sit on grass blades, which is why weed and feed generally won’t kill grass unless it is incorrectly applied. There are also liquid forms of weed and feed that are generally applied with a sprayer.
The “feed” portion of weed & feed is a fertilizer that contains some combination of nitrogen, phosphorous, and potassium to green up your lawn. The exact blend of fertilizer ingredients varies by brand, but all products will contain some percentage of nitrogen. Some products also include additional benefits, such as timed-released nitrogen for extended feeding.
When to Weed and Feed With Lowes Sta Green or Scotts
While feeding your lawn once a year will improve its condition, feeding it four times a year will make it even healthier. If you put your lawn on the regular schedule it will stay lush and green all season long.
Fertilize your lawn in the spring, early fall and/or late fall (such as late March, early April, early September and early November). However, if you live in an area with long, cold winters, then late April, August and the end of October may be best.
In most climates, late fall tends to offer better results because that’s when weeds grow stronger roots and take the herbicide to the roots along with it, killing them. You should also never fertilize any cool-season lawn during hot summer months.
If you live in the southern or western parts of the United States, such as Florida, Texas, Alabama or California fertilize your lawn in early summer and again in late summer or early fall. The application process is slightly different if you are using a product for southern lawns, such as Scotts Bonus S.
With all fertilizer schedules, you can add one treatment in midsummer, but avoid fertilizing when the temperature is too hot, particularly when it’s 85 degrees or above.
> Read our guide on southern weed and feed
Some Products Need Dry Lawn, Others Need Wet Lawn
For most areas of the United States, weed and feed products should be applied to a wet lawn either from rain or dew, on a calm day and left on the surface for 24 to 48 hours.
You can also wet the grass with a garden hose or turn on your sprinkler system for a few minutes before applying weed and feed.
The general exception is crabgrass control and southern weed and feed products.
Note: Scotts Bonus S, Sta Green Southern weed and feed and most crabgrass control products should be applied to a dry lawn.
A wet lawn helps fertilizer particles stick to the blades of grass and the weed leaves. To ensure that the particles have the best chance of doing their job, don’t water the lawn again for 48 hours.
If you’ve recently used grass seed, sod or sprigging, wait until your new grass has been mowed at least three times before applying any weed and feed product. For best results use a broadcast spreader set to the level indicated on the product package.
Early Spring: March – April. Step 1
Feeding your lawn in the spring strengthens roots and gets it off to a good start. Crabgrass control is the number one reason to use a pre-emergent fertilzer. If you had crabgrass last year, apply a combination fertilizer with a pre-emergent to control it.
Pre-emergents, such as those commonly used to prevent crabgrass, is weed control which must be applied before the weeds germinate. They are ineffective if the weeds are already actively growing.
You will only have about a 3 week window to apply Step 1. Use Scotts Halts plus Crabgrass Preventer or Sta-Green Crab-Ex Crabgrass Preventer. This early application is the most important part of getting a weed free and healthy green lawn. Yes, use it even if you didn’t have crabgrass last year.
Soil Temperature Map: Find your local ground temperature here
Step 1 should include pre-emergent weed killer and fertilizer used in early spring. This can be from mid March to late April.
Crabgrass normally germinates when the ground temperature reaches 55° F . This is also the ground temperature at which dogwood trees start to bud and forsythias begin blooming.
Late Spring: April – June. Step 2
Spring is prime time for lawns. Your grass is busy growing and using up stored energy. Step 2 weed and feed fertilizer is designed to strengthen existing grass and kill off weeds at the same time. Its also the best time to apply a weed and feed product.
Weeds want sun, water and food, which, is what your lawn needs too. That’s why you want to supply the lawn with a weed and feeding product designed for this time of year. Your grass is growing and unfortunately, broadleaf weeds are actively growing, too. It improves your lawn’s ability to absorb water and nutrients.
Weed & feed has a fertilizer to help “green up” your lawn. It also has a weed killer that targets broadleaf weeds like dandelions and many others. Many weed and feed products also have timed-release nitrogen for extended feeding.
The weed killer in post-emergent types of fertilizers are contact killers, and are effective only if the weeds are already actively growing. They will not kill weeds which have not yet germinated.
Applying in the spring and summer also gives your lawn a nitrogen booster that helps build the roots of your grass. Feed your lawn with a combination of fertilizer with broadleaf weed control like Scotts Turfbuilder with Plus 2 Weed Control or Sta-Green Weed and Feed.
Summer: June – August. Step 3
If you’re going to fertilize, remember the summer holidays of Memorial Day and Labor Day as the best times to apply. But what about summer months? What to do around the Fourth of July? Step 3 weed and feed products are designed for maximum effectiveness with a late-spring to mid summer application. They contain herbicides designed to kill actively growing broadleaf weeds like dandelions.
These herbicides are much more effective if you apply them in the spring or even the fall. At that time, the weeds are either growing or storing up reserves for winter and moving nutrients from the leaves to the roots. They move the herbicide to the roots at the same time, resulting in a better kill.
You can still apply weed and feed in the summer
It is not recommended to apply if the temperature will be above 90 degrees and no re-application of any fertilizer for another 30 days.
Summer is tough on grass. You can still apply a weed and feed product, but do so cautiously. Heat, drought, foot traffic, and insects stress it out. Feeding your lawn in the summer still helps to protect and strengthen it against these problems.
Lawns in warm-season grass areas should be fed over the summer months as they grow steadily from spring to fall. Also consider spot treatment of weeds by using a product such as Ortho Weed B Gon.
A more common problem you will see in the summer months are insects. If you see insects in your grass, use a feeding product that also contains insect control, such as Scotts Turf Builder with SummerGuard. For additional insect control try Ortho Bug B Gon Max granules or try Bug B Gone liquid spray around the perimeter of your home.
Fall: September – November. Step 4
Fall brings back ideal conditions for your lawn. Cool nights, ample rainfall and morning dew all contribute to new growth for your lawn and prime time for Step 4. If you missed an early spring application of weed and feed, now is the time to apply.
Since the lawn is ready to grow again, it is looking for the nutrients it needs to recover from summer damage. Some experts say this is the single most important lawn feeding of the year, more important than an early spring application. Apply your final feeding right before the winter months. You can apply a fall fertilizer until the average daytime temperature is above 50 degrees.
This means most regions of the United States can apply into late October. This will strengthen roots and increase nitrogen storage for an early spring green up next year. Try Scotts Turfbuilder with WinterGuard or Sta Green Weed and Feed Winterizer.
Planting Grass Seed or Aerating after Weed and Feed
Weed & Feed prevents seed germination, so you should avoid planting new grass or aerating your lawn for at least four weeks. If you apply weed and feed in the spring and summer, spread new grass seed and aerate in the fall each year.
Reasons Weed & Feed Didn’t Work
Remember to always follow the directions on the package. Always use a spreader to apply. Here are some common reasons why a weed & feed application could be ineffective:
- Weed & feed targets broadleaf weeds like dandelions, and dollarweeds. It does nothing for crabgrass and other grassy weeds. For these, you should use a pre-emergent like Scotts Halts or Sta-Green Crab Ex crabgrass preventer in the early spring. Must be applied before weeds and crabgrass are growing.
- Mature weeds are not actively growing, so the product will not be as effective. Weed and feed should be applied early in the growing season and a couple days after mowing.
- Rain and sprinklers can wash away the granules. Make sure there is no rain in the forecast and avoid watering for two days after applying.
What if You Apply Too Much Weed & Feed?
The best way to avoid damaging your lawn after too much fertilizer application is to flush out the weed & feed. Water your lawn with 1 to 2 inches of water for about 4 days. It would be best not to apply any other weed & feed fertilizer until the following year. Unfortunately, over watering can create run-off in certain drainage situations, so be aware of your location and where the water is going.
A Healthy Lawn With Lowes Using Scotts or Sta-Green.
Enjoy a lush, healthy lawn with Scotts Turf Builder fertilizer or Lowes exclusive Sta Green Products. Both combine essential nutrients for even feeding and weed control from early spring through late fall. Both provide uniform coverage and improves your lawn’s ability to absorb water and other nutrients to keep it healthy and looking great.
Remember to use the major summer holidays as your guide to the 4 step program: Step 1 Crabgrass in early spring. Step 2 Weed and Feed around Memorial Day. Step 3 Insect Control around July 4th. Step 4 Fall Fertilizer around Labor Day.
The 4 Step Weed and Feed Program-Make Your Own
The 4 step program from Scotts has been around for years. Did you know that it’s officially only available at local hardware stores and not Lowes or Home Depot? But, you can make your own version easily.
The bags sold at independent stores, like Ace Hardware, are a slightly different analysis and the bags will have each step number printed on each bag.
For example, here’s the difference in the first two applications of the 4 step process.
4 step bag: Step 1 for crabgrass ratio: 26-0-03. Step 2 Weed and Feed: 28-0-06
Lowes bag: Comparable Step 1 Halts crabgrass ratio: 30-0-04. Comparable Step 2 Weed and Feed : 28-0-03
Not a big difference. Sure, you can make a 4 step program simply by purchasing the four bags at Lowes or Home Depot, and many of us do, but the actual 4 step Scotts fertilizer program is only available at your local hardware.

Before You Buy
Maintaining a healthy lawn includes mowing, weeding, watering, and fertilizing. However, fertilizing isn’t always necessary. Over-fertilizing your lawn will make the grass grow more vigorously, causing you to have to mow more frequently or lead to run-off which ends up in your local watershed.
Excessive fertilizing can result in lawn burn, which is when the nitrogen and salt levels in the soil are too high and cause yellow to brown strips or patches of dead grass. A lawn, as with any type of plant, only needs fertilizing if the soil lacks the vital nutrients to help it grow. In situations like these, fertilizing your soil is essential.
Types of Weed and Feed
Weed and feed comes in two forms: liquid and granular. Although the liquid forms are easier to apply and provide faster results, it’s more economical to use the granular form. Spray or liquid weed and feed are designed for small yards. Granular weed and feed covers more area, often 5,000 square feet or more, and are available in 18-lb bags and larger. Granular versions offer a better value for your money, but you do need to water your lawn after application for it to penetrate the grass.
Some weed and feed feature slow-release formulas so you don’t have to fertilize as often. However, to achieve good results plan on treating your lawn at least once every eight weeks from the start of spring.
What to Consider When Choosing the Best Weed and Feed
Type of Turf Grass
The best weed and feed product for your lawn depends on the type of grass you have. Grass species have different nutrient requirements, so not all of them are safe for every species of grass. Using the wrong product can damage your grass. In general, grass species are divided into two categories: warm season and cool season. The seasons do not refer to the time of year, but the climate and average soil temperature range.
- Warm-season turfgrasses grow best with average soil temperatures between 80 and 95 degrees Fahrenheit. Warm-season grasses thrive in warmer climates found in the Southeastern and Southwestern United States and include Bahia grass, Bermuda grass, carpet grass, Saint Augustine grass, and zoysia grass (Japanese lawn grass).
- Cool-season turfgrasses grow best with average soil temperatures between 60 and 75 Fahrenheit. Cool-season grasses thrive in the cooler climates of the Midwest and Northern regions of the United States. Some cool-season grasses are Kentucky bluegrass, perennial ryegrass, and tall and hard fescue.
Selecting a fertilizer and weed killer that’s compatible with your grass species will give you far better results.
To grow a lush lawn, your soil needs to have essential nutrients. Fertilizers temporarily add nutrients to the soil. Fertilizers denote their nutrient ratios as NPK. This denotation represents the percentage of nitrogen (N), phosphorus (P), and potassium (K) in the product. This is how the nutrients help grass:
- Nitrogen helps the grass to grow properly and develop a green color.
- Phosphorus helps to develop strong root systems.
- Potassium protects plants from disease, drought, and cold.
There are at least 11 states that ban phosphorus fertilizer use or sale. Luckily, many lawn weed and feed products available have adapted to this and have removed phosphorus from the product. Don’t worry—the weed and feed will still green up and thicken the grass without the additional phosphorus.
Fertilizers can also contain secondary elements and micronutrients needed for healthy growth such as sulfur, calcium, magnesium, boron, iron, molybdenum, zinc, copper, chloride, nickel, and manganese. To find out exactly what nutrients your lawn needs can be determined by conducting a soil test. You can either purchase a test to use at home or take a soil sample to your local cooperative extension testing office.
Many fertilizers also have built-in herbicides or weed preventatives. Some products are better at killing certain types of common weeds and pests than others. In general, most weed and feed target common types of broadleaf weeds including plantain, chickweed, creeping charlie, dandelions, and clover.
Weed preventers, or pre-emergent weed killers, block weed seeds that are already in the soil, like crabgrass, poa annua, chickweed, and henbit, from germinating. Identify the type of weeds that are infesting your lawn and then make sure you choose a product that’s made to take care of it.
