Finding Deficiencies

Those just getting into gardening, or any sort of green-thumb activity, may not know quite how important fertilizer is. Fertilizer is designed to fill in the nutrients your ground may be lacking so you can achieve optimal growth.

There are three primary types of nutrients: nitrogen, phosphorus and potassium. Nitrogen helps plants grow and makes them look extra green, which is typical what one strives for in plant growth. Phosphorus helps out with the growth of roots and any fruit, seeds or flowers the plant produces. Finally, potassium, sometimes referred to as potash, also helps out with the roots and works to protect plants from drought and disease.

In addition to these elements, fertilizers can also help with deficiencies in oxygen, carbon, calcium, magnesium, boron, cobalt, iron, manganese and more. These are needed in much smaller amounts, so you’re really mostly looking to fill out the three primary items, but that secondary stuff helps.

The first step in choosing a fertilizer is to find out what your yard needs, which can be determined by doing a soil test. You can purchase a test to run for yourself at home or you can take a sample of your soil to a cooperative extension testing office, if there is one in your area. Either way, you’ll be able to find out what you need.

Learning to Read

On each bag of fertilizer, you will find three numbers. These represent the NPK value, with NPK standing for the atomic symbols for nitrogen, phosphorus and potassium. The value is shown as x-x-x, with each number representing a percentage of the whole.

For instance, a 20 pound bag of fertilizer with an NPK value of 15-5-6 would be made up of 15 percent nitrogen, five percent phosphorus, and six percent potassium. So that 20 pound bag would include three pounds of nitrogen, one pound of phosphorus and 1.2 pounds of potassium. Everything else in the bag is just stuff to fill in the space so the nutrients are properly distributed, along with some of those secondary nutrients.

Different Types

Fertilizer also comes in different types. You may be most familiar with the kind which looks like soil, but fertilizer can also come in a liquid form and others in a granular form. Both of these also come in their own subtypes. Liquid can come in a concentrated form which you need to dilute with water and spread around using some sort of pressurized sprayer or a watering can. There are also some which come in neat attachments which can be placed on the end of your hose and sprayed around. These come with excellent benefit of not having to deal with mixing anything. Simply screw it on and get to spraying.

Granular fertilizers also take some special equipment if they are to be released evenly. You can use a special container and shake the granules around your yard or you can use a mechanical spreader, which can be handheld or more like a cart. These mechanical ones spin and launch the fertilizer all over the place, making sure the yard is completely covered.

More specifically, there are two types here, quick release and slow release granules. Quick release tend to break down quickly, imparting their nutrients into the soil once they are hit with water. With a quick release fertilizer, you need to spread it about once a month. Slow release types can be covered in sulfur, which can last for two months, or polymer, which can keep you good to go for nearly four months.

One final type is the plant food spike, which is literally a spike made of nutrients which you stab into the ground and is absorbed overtime by the surrounding plant life. These are great for indoor plants, trees, shrubs or any other specific plant, as opposed to something you would use for your yard.

Feeding Your Yard

Types of Grass
To get to the specifics of today’s reviews, we need to look at yard fertilizers. Chances are, if you want to find the best lawn fertilizer with weed control it’s because you want to get your lawn looking fantastic. We already discussed making sure you know the nutrients in which your soil is deficient so you can choose the right balance of nutrients. We also discussed the different types of fertilizers.

There are a couple things to keep in mind, as well. First, you should know which type of grass you have in your yard. Different kinds of grass require different types of nutrients. Generally, you can choose a one-size-fits-all type of fertilizer, but your results won’t be as good as with something specific for your type of turf. You also need to be mindful of the area in which you live. If it tends to freeze over in winter, consider getting a fertilizer designed to prepare your yard for the coming season, for instance. There are fertilizers out there for pretty much everything, so investigate these things.

In order to keep your yard looking good and keep it free from weeds, you’re going to want to use a weed and feed lawn fertilizer. As with any other kind of fertilizer, weed and feed comes in multiple varieties and there are instructions you should follow on the bag. You’ll be able to see what levels you should set your spreader, which types of weeds it kills and how much of the stuff you should use. Obviously, these are pretty important bits of information, so take the time to read the small print or else you could end up with a yard full of crabgrass which is half burnt from using too much nitrogen.

The Products

The sheer number of weed and feed fertilizers out there is astounding, and they can range from inexpensive to a pretty penny. While all do a decent job, some are definitely better than others. Fortunately, these can all be found easily at either an online retailer or a local store, should that suit your fancy.

Reviews on Best Fertilizer with Weed Control

Scotts Turf Builder Weed and Feed Fertilizer

Additional Information

  • NPK Value: 28-0-3
  • Packaging: Bag
  • Application: Up to twice per year with at least 30 days between applications.
Scotts is one of the more common names in the yard fertilizer category. You can find it pretty much anywhere and it doesn’t cost a whole lot. It also does a good job, though perhaps not the best. In its latest iteration, it handles dandelions and clovers handily, and it claims to be twice as strong as it previously was. You can purchase the Scotts Weed and Feed in four different sizes and it only needs to be applied twice per year. It works on more than a handful of grass types, but if you have St. Augustine, Dichonda, Lippia, Carpetgrass or Bentgrass, you should look for another brand.


  • Inexpensive
  • Easy to find
  • Usable on many grass types
  • Only needs to be applied twice per year


  • Not usable on all grass types
  • Harmful to people and pets in first 24 hours
  • Not the best feed

Pennington Signature Series Weed and Feed Northern Fertilizer

Additional Information

  • NPK Value: 28-0-4
  • Packaging: Bag
  • Application: Unavailable
The Pennington brand makes a lot of claims about their product. They say it can kill more than 250 kinds of weeds, including dandelions, white clover, plantains, chickweed and more. They also say it will make your yard greener very quickly and that it will last quite some time without needing additional feeding.


  • Long lasting
  • Kills large number of weed types


  • Not much information available

Espoma Organic Weed Preventer

Additional Information

  • Coverage: 1250 sqft
  • Packaging: Bag
  • Application: twice each year
Right up there with Scotts, Espoma has been in the business for quite some time. Their Organic weed preventer is an all natural organic product that you should feel confident and safe in using on your property. It’s easy to use, though perhaps not as easy as using a push spreader. One thing to keep in mind, this is a preventer, not a killer. If weeds are already growing, you’re not going to have a great time. The earlier you get this on your yard, the better. It’s said that you only need to use it twice a year, which is also a plus.


  • Easy to dispense
  • Organic product
  • Prevents weeds


  • May have to use more than other brands
  • Takes some getting used to

Preen Lawn Step Saver Weed Control Plus Lawn Fertilizer

Additional Information

  • NPK Value: 24-0-6
  • Packaging: Bag
  • Application: Once every two months
If a greener, weed free lawn is on your bucket list, perhaps this Preen product will help you achieve it. Not only does it kill broadleaf and the dreaded crabgrass, it also deals with some 200 other types of weeds commonly found in lawns. It does it all while helping many of the more popular grass types grow. It is not, however, to be used on St. Augustine grass in Florida, dichondra or carpet grass. It will cause some pretty heavy damage to these types of grass.


  • Handles many weed types
  • Good on most types of grass


  • Somewhat expensive
  • Needs to be applied often
  • Dangerous to a couple popular grass types

Spectracide Weed & Feed

Additional Information

  • NPK Value: 20-0-0
  • Packaging: Bottle
  • Application: Twice per year with 30 days between applications
Most of my experience with Spectracide has been with products used to kill bugs in my yard. For that, it has worked fantastically well. I can only imagine the same when I see it being used to kill weeds. If it can knock out weeds and fertilize the yard at the same time, I think this is a product worth a little attention. Unlike all our other offerings, the Spectracide Weed & Feed comes as a liquid in a bottle which attaches to your hose for easy distribution. It may not control quite as many types of weeds as these other products, but the amount of covers is still pretty impressive.


  • Easy application
  • Inexpensive
  • Easy to find
  • Long lasting


  • Perhaps not as effective
  • Hazardous to people and pets

And the Winner Is

For pure ease of application and effectiveness, my vote has to go to the Spectracide Weed & Feed. With no need for any additional tools aside from a garden hose, which you should already have so you can water your lawn, and with the ability to kill off a very large number of weeds while still feeding the yard, this is a great product. However, with it’s NPK value showing it pretty much only provides nitrogen for your yard, other products may be better.

With the information provided, you should be able to go out and pick the best possible fertilizer with weed killer for your yard. It’s going to take a little planning to make sure you have exactly what you need, but when you do, your yard is going to look cleaner and greener than anybody else’s on the block. Don’t you want your lawn to be the envy of the neighborhood?
