Weed and Feed vs Fertilizer for Lawn: Which Option is Best for Your Grass?
Trying to get the best lawn possible but not sure if you should use weed and feed or regular fertilizer? Knowing the difference between these products can help you avoid mistakes and keep your grass looking healthy. Read on to learn which option is right for you.
Choosing the right product for your lawn can make a big difference in your lawn’s appearance. Weed and feed combines fertilizer with weed killer to help your grass grow while also controlling common weeds, but regular fertilizer only feeds your grass without treating weeds. Picking the best option depends on your lawn’s current condition and what you want to achieve.
If you just want greener, thicker grass and don’t have a lot of weeds, you may only need fertilizer. If your lawn has unwanted weeds popping up all over, weed and feed might be the better choice. Understanding how each product works can give you the best odds of keeping your lawn looking great all season long. Let’s take a look at weed and feed vs traditional fertilizer products.
Key Takeaways
- Weed and feed treats weeds and feeds your grass at the same time.
- Use plain fertilizer when you don’t have many weeds.
- Using the right product helps you get the lawn you want.
Understanding Weed and Feed Products
Weed and feed is a popular option for people who want to fertilize their grass and control weeds at the same time. This section explains what these products are, how they work, and the main types you can find in stores.
What Does Weed and Feed Mean?
Weed and feed describes a combination lawn care product that both kills weeds and adds nutrients to your grass. The “weed” part targets unwanted plants, often broadleaf weeds like dandelions and clover. The “feed” part works like regular fertilizer, providing nutrients such as nitrogen, phosphorus, and potassium.
These products are made to save time because you apply them in just one step. Many homeowners use weed and feed during the growing season to keep their lawns green and weed-free. You might see these products labeled as “all-in-one” or “complete” lawn care solutions at your local store.
How Weed and Feed Works
Weed and feed products use a mix of herbicide and fertilizer. The herbicide is usually designed to stick to the leaves of broadleaf weeds and kill them without hurting most grasses. The fertilizer helps your grass grow thicker and greener.
Most weed and feeds come as granules or in liquid form. Granular products are usually spread over dry grass, while liquid weed and feeds need to be sprayed onto wet leaves to help the weed killer stick. Timing is important. Apply weed and feed when weeds are actively growing and your grass can absorb the extra nutrients.
Some weed and feed products target only certain weeds, so always check the label. Be careful with application, as using too much can damage your grass or nearby plants.
Common Types of Weed and Feed
There are two main types: pre-emergent and post-emergent.
- Pre-emergent weed and feed: Stops weed seeds from sprouting, but won’t kill existing weeds. It’s best to use this in early spring, before most weeds start to grow.
- Post-emergent weed and feed: Targets weeds that are already growing in your lawn. This is the more popular type for broadleaf weeds like dandelions and clover.
Weed and feed products are sold as either granular formulas (spread with a spreader) or liquid sprays (attached to a hose or used in a sprayer). Not every type works with every lawn or every weed. Always read the product details and application instructions before you buy.
Weed and Feed vs Fertilizer: Key Differences
Weed and feed and regular lawn fertilizers have different goals, ingredients, and ways to use them. Choosing the right one depends on what your lawn needs most—greener grass, fewer weeds, or both.
Primary Purposes
Weed and feed is made to do two jobs at once. It helps kill common lawn weeds like dandelions and clover while giving your grass important nutrients to help it grow.
Lawn fertilizers only feed your grass. They do not target weeds. Fertilizers are best if your main goal is thicker, greener grass.
If you have a lot of weeds and also want better grass growth, weed and feed can save time since it works on both at once. If you just want to boost your lawn’s health, a plain fertilizer is a simpler, more focused choice.
Active Ingredients Comparison
Weed and feed mixes contain both fertilizers and herbicides. The types of herbicides vary. Some target only broadleaf weeds, while others target grassy weeds too. Common herbicides include 2,4-D or dicamba.
Fertilizers are mainly made from three key nutrients: nitrogen (N), phosphorus (P), and potassium (K). You might see these listed on the bag in numbers like 20-0-10.
With weed and feed, you get both nutrients and weed control in every application. With fertilizer, you only add nutrients, so you have more control over what goes onto your lawn.
Table: Comparison of Active Ingredients
| Product Type | Main Ingredients | Weed Control? |
|---|---|---|
| Weed and Feed | N, P, K + Herbicides | Yes (Broadleaf/Grassy) |
| Fertilizer | N, P, K | No |
Application Timing
When you use each product matters. Weed and feed should be put on your lawn when weeds are growing and not when the grass is dormant. For most people, this means spring or early fall is best.
Weed and feed won’t work as well if you apply it before weeds have come up or when the weather is too cold or hot. Make sure not to mow right before or after application—this lets the product stick to and kill the weeds.
Fertilizers can be used more flexibly. You can feed your lawn in early spring, summer, and early fall, depending on the type of grass you have. Fertilizer-only products do not need to wait for weed problems.
Longevity of Results
Weed and feed products work for a shorter period. You may need to reapply every few months if weeds come back or nutrients get used up. Most products last about 6–8 weeks.
Fertilizer alone can last longer, especially slow-release types. Some fertilizers keep feeding your grass for up to 12 weeks, which means fewer applications each year if the lawn is healthy and weed problems are minor.
Repeat use of weed and feed can stress your lawn if used too often. With fertilizer, you can adjust the schedule based on your lawn’s needs and growth rate. This makes it easier to avoid overfeeding or harming your grass.
When to Use Weed and Feed Instead of Regular Fertilizer
Weed and feed can save time if your yard has both weeds and needs nutrients. Using it correctly depends on what is going on in your lawn and the specific conditions you notice.
Common Lawn Scenarios
If you see patches of weeds like dandelions mixed in green grass, weed and feed may help. This product combines fertilizer with weed killer, so you can attack two problems in one step. It comes in handy in the spring when you first spot weeds starting to grow.
You usually use weed and feed when your lawn is established, not for new grass or seeding. If your grass is thin and weeds are spreading fast, weed and feed can offer a quick fix. People often pick it when they want a low-effort routine instead of separate treatments.
However, if your yard is mostly weeds, it’s better to control weeds first before applying fertilizer. Weed and feed works best when you have more grass than weeds and just need to boost lawn health while knocking out a few broadleaf weeds.
Lawn Conditions That Favor Weed and Feed
Weed and feed is most useful during certain times of the year. Spring and early fall are the best because weeds are actively growing and grass is waking up from dormancy. The product will not work well when the ground is frozen, too dry, or during summer heat.
Your lawn must be moist for weed and feed to stick to weed leaves. Morning dew or watering the night before helps this. Avoid using it after mowing; wait a couple of days so there is enough leaf to absorb the product.
Some lawns have more weeds in shady or high-traffic areas. If these spots show up along with overall grass needing a nutrient boost, weed and feed is a good choice. But never use it on newly seeded lawns or delicate grass types, as it may slow new growth. If your grass is healthy with no weeds, regular fertilizer is better.
When to Choose A Standard Fertilizer Over Weed and Feed
Sometimes, a regular lawn fertilizer is all you need to feed your grass and help it grow strong. Choosing fertilizer instead of weed and feed can protect your yard and target your lawn’s real needs.
Ideal Times for Fertilizer-Only Applications
If your yard has very few or no weeds, it makes more sense to use standard fertilizer. This avoids adding unneeded weed killers to your grass, which can hurt healthy plants.
Early spring and late fall are popular times for fertilizer-only treatments. In spring, your lawn wakes up and needs nutrients to grow. In fall, your grass needs to store food for winter.
You should also pick fertilizer-only after newly planting grass seed. Weed and feed can damage new seedlings, but fertilizer helps them root and spread.
Best Practices for Fertilization
Test your soil before you start. A simple soil test tells you which nutrients your lawn may be missing, so you can pick the right fertilizer.
Follow the instructions on the fertilizer bag for the right amount and timing. Use a spreader to apply fertilizer evenly so your whole lawn gets the same treatment.
Water the lawn after spreading fertilizer unless the product says not to. This helps nutrients sink into the soil and reach grass roots.
Repeat as needed throughout the year, based on your grass type and local weather. Keeping a regular schedule gives your lawn steady support.
How to Properly Apply Weed and Feed
It’s important to prepare your lawn carefully before using a weed and feed product. Correct application helps avoid damage and gives the best results for your grass and weeds.
Preparation Steps
Start by mowing your lawn a day or two before you plan to use weed and feed. This keeps the grass at a manageable height, making it easier for the product to reach the soil where it’s needed most.
Make sure the grass is slightly damp. Early morning, when there’s dew on the lawn, is a good time. Damp grass helps the weed control stick to the weeds better.
Check the weather forecast. Avoid days with heavy rain or strong wind. Rain soon after application can wash the product away, and wind can spread it to places you don’t want, like flower beds.
Clear any debris like leaves or sticks from your lawn. This lets the weed and feed touch the grass and weeds directly.
Read the instructions on your product’s label. Each brand may have different guidelines for safety and best results.
Best Application Techniques
Use a broadcast or drop spreader for granule weed and feed. This helps you get even coverage across your yard.
Walk at a steady pace to keep the spread even. Overlapping rows at the edges prevents missed spots.
If you’re using a liquid version, use a hose-end or pump sprayer. Spray in straight lines, being careful not to double up or miss patches.
Tips for Application:
- Apply when weeds are growing, usually in spring or early fall.
- Avoid application on newly seeded lawns.
- Keep pets and kids off the grass until it’s dry or as directed.
Water the lawn lightly a day or two after application, unless rain is expected. This helps the fertilizer move into the soil but gives time for the weed killer to be absorbed by the leaves.
Clean your spreader or sprayer after each use to prevent buildup and avoid chemical mixing.
Results and Expectations
When you choose between weed and feed or fertilizer, you will see differences in how your lawn looks and how fast it changes. Each product delivers its own results, so it’s important to know what to look for and when you might see it.
Visible Changes in Lawn Appearance
With weed and feed, you can expect two main things: greener grass and fewer weeds. After spreading it, weeds like dandelions may start to wilt and turn brown within about a week. Your grass can gain a richer green color, especially if it was pale before.
Weed and feed does not target all types of weeds. It mainly works on broadleaf weeds but may miss some grassy weeds or tough patches. Sometimes, patches without grass will remain bare because weed and feed does not plant new grass seeds.
Fertilizer on its own will not kill weeds. Its main job is to help your grass grow thicker and stronger. You may notice more even growth and deeper green blades, but any current weeds will likely stay unless you pull them or use another weed killer.
Timeframe for Improvements
Weed and feed usually begins to show results within 7 to 14 days. Wilting and dying weeds are often the first sign. Grass color can improve in one to two weeks, depending on how healthy your lawn is already and the weather.
Fertilizer effects on grass color and growth appear about 5 to 10 days after application. You may see a brighter lawn fairly quickly. Weed reduction, though, will not happen with just fertilizer.
For both products, best results often depend on proper watering and the right weather. Too much rain or lack of water can slow down changes. Do not expect bare spots to fill in unless you also seed your lawn.
| Product | Green Grass | Kills Weeds | Time to See Changes |
|---|---|---|---|
| Weed and Feed | Yes | Yes | 7-14 days |
| Fertilizer Only | Yes | No | 5-10 days |
Potential Risks and Considerations
Choosing between weed and feed and regular fertilizer brings up a few important concerns. Each product interacts with your lawn, your family, and the environment in different ways.
Risk of Lawn Damage
Applying weed and feed or fertilizer in the wrong way can harm your grass. If you use too much weed and feed, the chemicals may burn your lawn, especially during hot weather or when your lawn is already stressed. This is because weed killers and fertilizers together can be strong on your grass.
Some fertilizers can also cause problems if you apply too much. This includes nutrient imbalances and yellow or brown patches. If you use the wrong product at the wrong time of year, you may stop grass seeds from sprouting.
To reduce risk:
- Follow label instructions exactly
- Avoid use during high heat or drought
- Never over-apply any product
Child and Pet Safety
Weed and feed products often contain herbicides that can be harmful if touched or swallowed. You should keep kids and pets off the grass for as long as the product label advises, which is usually until after it dries or sometimes longer.
Regular fertilizers can also cause mild skin or stomach upset if children or pets contact them. Always store these products out of reach and wash hands after spreading them.
Here’s what you can do to protect your family and pets:
- Keep people and animals away from the lawn until it’s safe
- Wash hands and paws after being on treated grass
- Store products safely
Environmental Impacts
Weed and feed and some fertilizers can end up in storm drains, streams, or lakes after it rains. This can hurt fish and other wildlife by causing algae blooms or water pollution. Herbicides that drift or run off can also damage gardens, flowers, or wild plants nearby.
Using more product than needed increases these risks. Natural or organic fertilizers may be safer for water, but they still need to be used responsibly.
To help protect the environment:
- Apply products only when needed
- Sweep extra material off sidewalks or driveways
- Choose products with less runoff risk when possible
Cost Comparison: Weed and Feed vs Fertilizer
When thinking about costs, it’s helpful to look at both short-term and long-term spending. Weed and feed products combine weed control and fertilizer, while regular fertilizer is just for feeding your grass.
Average Costs
- Weed and Feed: You can usually find bags priced from $20 to $60 depending on brand and coverage size.
- Fertilizer only: These are a bit less, ranging from $15 to $50 for a similar size.
Here’s a quick table to show typical prices for a single treatment:
| Product Type | Low End | High End |
|---|---|---|
| Weed and Feed | $20 | $60 |
| Fertilizer Only | $15 | $50 |
Name-brand products, like Scotts, often cost more. Store brands or generic versions can save you $10–$15 per bag.
DIY treatments are usually cheaper per application than hiring professional lawn services. On average, lawn fertilization by a service costs about $289, but prices can range from $103 to $343 based on your lawn size and local rates.
Other Things to Consider
- Weed and feed might save you time by combining two products.
- Fertilizer alone gives you more control over when and how you treat weeds.
- Ongoing costs can add up if you treat your lawn more than once per year.
You should match your choice to your lawn’s needs and your budget.
Frequently Asked Questions
Choosing between weed and feed and regular fertilizer can be confusing. The right choice depends on your lawn’s needs, timing, safety, and how products can affect the environment.
What’s the difference between using weed and feed and regular fertilizer for my lawn?
Weed and feed is a two-in-one product. It contains both fertilizer for your grass and chemicals that kill weeds.
Regular fertilizer only feeds your lawn and does not kill weeds. You’ll need to treat weeds separately if you use only fertilizer.
When is the ideal time to apply weed and feed to my lawn?
Early spring or fall are the best times to use weed and feed. The weeds need to be actively growing for the product to work well.
Avoid applying during very hot, dry, or wet weather. Always follow the instructions on the package for timing.
Can weed and feed products harm my lawn or garden if not used properly?
Yes, using too much weed and feed or applying it at the wrong time can damage grass. The herbicide part can also hurt flowers, shrubs, or trees if it drifts or washes away.
Make sure to only use it on the types of grass listed on the label. Keep it away from gardens and water sources.
What should I look for when choosing the best weed and feed for my lawn care routine?
Check that the product matches your grass type and the weeds you want to control. Choose a formula that fits your region and the season.
Read labels for important details, such as coverage and application instructions. Safety directions matter, too.
Are there any environmental concerns associated with using weed and feed?
Weed and feed products can move into water after rain or watering. This may harm nearby streams and plants.
Overuse can also hurt helpful insects or soil health. Proper application helps lower the risks.
What are the disadvantages of using weed and feed compared to traditional fertilizer?
Weed and feed can’t always be applied exactly when your grass or weeds need it most. Applying both at once can mean one part will not work as well as it should.
You also have less control over where the chemicals go. More targeted care is possible if you treat weeds and fertilize separately.
