Pennington UltraGreen Weed & Feed

If you are looking for the best weed and feed at a good affordable price, Pennington UltraGreen Weed and Feed is a great choice. This excellent fertilizer comes with Nitrogen, making it the most potent weed killer while preserving your other plants. You can safely use it in your lawn to kill over 250 broadleaf weeds, including dandelion, henbit, dollar weed, White clover, plantain, and chickweed to keep your property tamed. It also worked great with both northern and southern grasses.

This stuff is really easy to use, another reason we liked it. Just apply granules evenly all over the lawn. It works really fast too, it started working for us in about three days. One thing we liked about the Pennington, in particular, is it also has slow-release Nitrogen, which extends the feeding for up to three months.

Scotts Turf Builder Fall Weed and Feed

Scotts Weed & Feed

Scotts Turf Builder was great. It contains pre-emergent and lawn food to promote grass growth and still kills unwanted weeds. It is also made to last up to six weeks.

Things that make it one of the best weed and feed is its “weedgrip” technology, which offers exceptional control over clovers and dandelions. Like the Pennington the version we got was granular and it was very easy to put down.

The Scotts can also work on many common kinds of turfgrasses such as Centipede grass, Ryegrass, fescue, Bahia grass, Kentucky bluegrass, Bermuda grass, and Zoysia grass. It is not recommended for warm-season grasses like Saint Augustine grass, carpet grass, or Dichondra grass. It is meant to be used in the fall to bring your lawn back stronger in the spring.

Scotts Turf Builder Triple Action Weed and Feed

Scotts Triple Action Weed & Feed

We weren’t sure if we should put two weed and feeds on this list from Scotts but we just liked this one so much we had to add it. It pretty much kills every type of weed you can think of. Moreover, it is specially intended to use for Northern grasses like Kentucky bluegrass, Perennial Ryegrass, Tall Fescue, and Fine Fescue.

Like the others this was granular and it went down super easy. They do recommend that you figure out how much you need before putting it down because if you put down too much it can kill other stuff besides just the weeds. Thankfully they actually have a Scotts App that can help figure out how much you need. You also need to be careful since this stuff can be harmful to pets or children.

  • Relatively pricey
  • Harmful to pets and children

Spectracide Weed & Feed

Spectracide Weed & Feed

The Spectracide Weed & Feed was a great all-arounder for us. It is mainly for broadleaf weeds and has a really easy spray applicator that you just hook up to your hose and water like you normally would. You should read the directions, one thing that we were surprised by is that once you put this down you are not supposed to water for 24 hours after.

The Spectracide as what it calls a “dual-action” formula kills dandelion, chickweed, knotweed, plantain, clover, mallow, purslane, and almost all broadleaf weeds. The fertilizer did a great job of feeding the lawn too. This was another one that warned against using around children or pets so that might be something to consider as well.

  • Contain a QuickFlip hose-end- sprayer, which offers quick activation at the flip of a switch
  • Long-lasting 


  • Harmful for people and pets, so stay away from the place after application
  • Not as effective

Scotts Liquid Turf Builder with Plus 2 Weed and Feed

Scotts Liquid Weed & Feed

Ok, three products from Scotts on this list? What are we, paid by Scotts? Just kidding, but seriously Scotts is one of the best names in yard fertilizers. We really liked this one because it is simply a spray attachment to your hose, just put it on the end of the hose and spray. Moreover, the sprayer also contains a QuickFlip hose-end, which allows you to switch off the sprayer for accurate application easily, and that is fantastic.

Besides being potent, this stuff works fast. It kills all the weeds and fertilizes your lawn within twenty-four hours, which we also liked. This stuff got rid of all the dandelions, clover, and other lawn weeds such as buckhorn, chickweed, ground ivy, henbit, knotweed, lambsquarters, oxalis, pigweed, plantain, poison ivy, ragweed, and spurge.


  • Weight: 2.7 pounds

  • QuickFlip switch at the sprayer allows you to switch off the spray for a controlled, accurate application
  • Relatively affordable price 


  • The spray may clog after multiple uses

GreenView Weed and Feed

Green View Weeb & Feed

We really liked GreenView because it stays working on your lawn for up to eight weeks which is amazing. You basically put it on once and forget about it. This weed and feed also is specially formulated to focus on the roots and build them up making the grass much more resistant to future damage.

Again the granular application is very effortless, but you need to apply it on a wet lawn. Doing this makes the granules stick to the leafy part and transport deep into the root for effective killing and feeding.

Greenview kills up to 250 different weeds such as dandelions, clover, plantain, chickweed, ground ivy, and thistle. However, it is not useful for St. Augustine grass, Dichondra, and Carpetgrass. Hence, if you live in Florida, maybe it would not be as effective as for others. Moreover, it is also not recommended to use on newly grown grasses. It may result in burning and stunted growth, so be cautious.


  • Weight: 13.62 pounds
  • Dimension: 17.25 x 12 x 6 inches
  • Liquid or Granular: Granular
  • Child and Pet-Friendly: No
  • Coverage: 2,500 to 15,000 square feet


  • Stays in the plant for up to eight weeks
  • Built to create a healthy root system
  • Provide extra resistance from drought and heat
  • Knockdown up to 250 different weeds, giving you a weed-free garden
  • Granules are very easy to apply


  • Not useful for St. Augustine, Dichondra, and Carpetgrass
  • Cause burning and stunted growth if used on newly grown grasses

Buyer’s Guide

Above, you have read brief reviews of some of the best weed and feed with their specification, pros, and cons. Now you have an  idea about which weed and feed might be best for you. We also wanted to metion some points about weed & feed in general in case you are a beginner.

Let’s have a look.

Testing your Soil

Soil plays a crucial role in the health of your lawn. It not does it provide nutrients, water, and air but also stabilizes the plant’s roots. In gardening, everything starts with the soil. Therefore testing your soil is the most crucial thing before applying anything to your lawn. Fertilizers add essential nutrients ratios depending upon the need of the soil. After testing, you will know which nutrients your soil needs. This will help you to choose the best fertilizer.

Type of Grass

This is another thing to think about before you choose a weed and feed. There are two main categories of grass: cool season and warm season. Both have different nutrient requirements and react differently to fertilizers. 

Warm-season grasses are found in warmer areas, such as Southeastern and Southwestern United States. They grew best with average soil temperature from 80 to 95 degrees Fahrenheit. Saint Augustine grass, Zoysia grass, Bahia grass, Bermuda grass, and Carpet grass are some warm-season grasses. On the other hand, cool-season grasses thrive in cooler areas such as the Midwest Northern regions of the united states. The average soil temperature for their growth varies from 60 to 75 Fahrenheit. Kentucky bluegrass, perennial Ryegrass, and tall and hard fescue are some cool-season grasses.

If you don’t know the type of grass, you could buy the wrong weed and feed which could destroy your entire lawn. A good idea is to first take a sample of your lawn grass to a nursery so they can tell you what type it is. Then choose the fertilizer based on which type of grass you have. 

Targeting Weeds

Another important thing you should know; all lawns do not suffer from the same weed problem. Many weed and feeds work only on certain types of weeds, usually common broadleaf species like chickweed, creeping Charlie, dandelions, clovers, and plantain. On the other hand, weed preventers block weeds by inhibiting their growth.

Hence, you must know the type of weed infesting your lawn and buy the product that’s is made for that specific type of weed. In the list above we call out what type of weeds each one works best on but it might be worth looking into the weed itself on Google just to make sure you have the right plan of attack.

Type of Weed and Feed:

There are two categories of weed-and-feed in the market; Liquid or Granular. Both have benefits and drawbacks. The liquid is easier to use and highly effective, but it is ideal for small yards. On the other hand, if you have a big yard, a granular form of weed-and-feed is better.

Liquid fertilizers are more immediate and provide nutrients to the soil instantly; hence, the results will be visible only in a few days. However with liquid weed and feed you might need to reapply more frequently. Granular slowly releases nutrients to the soil, which retains for many weeks; therefore, you don’t need to apply it as often.

Tips for Feeding Your Lawn

Timing is everything. If you feed your lawn at the proper time it will use all of the fertilizer. If you put the weed and feed down at the wrong time of day it might not help much at all. Generally the best time to start using a weed and feed is the early spring season. When you use a slow-releasing formula, you should not need to feed it again until mid-may. 

If you still think you need to apply more you should wait until the end of summer, it will prevent your lawn from over-fertilization. Always keep in mind, the second feeding should happen about two months after the first. It will prevent the chemical from building up in the soil. After the may-feeding, fertilize every six to eight weeks after straight up to October.

Moreover, it’s essential to keep watering your lawn throughout the summer after feeding. If you don’t, you’ll probably end up causing burning and patches of grasses.
