How To Choose The Best Lawn Weed And Feed
The perfect weed and feed matches your lawn size, the specific weeds you are fighting, and how often you want to reapply. These are the specs that separate a winning purchase from a wasted trip to the spreader.
Coverage Area vs. Bag Weight
A big heavy bag does not always mean it covers the most ground. The Jonathan Green bag covers 15,000 square feet of lawn despite being 45 lb, while the Pennington covers only 4,000 square feet from a 14.4 lb bag. Always check the coverage number, not the weight in your hands.
Nitrogen Analysis and Release Type
The first number in the analysis, like the 25 in 25-0-8, is the nitrogen percentage. You want enough nitrogen to green up your grass without burning it. Slow-release formulas, like the polymer-coated urea found in the Pennington product, feed gradually over months rather than all at once.
Weed Kill List vs. Your Specific Weeds
Not every weed and feed kills everything. The Jonathan Green product controls over 250 weeds including dandelions and poison ivy, while the Scotts formula is designed for dandelions and clover using Weedgrip Technology. Check what is invading your yard before you choose.

In‑Depth Reviews
1. Jonathan Green Veri-Green Weed and Feed Lawn Fertilizer (16003)
The broadest weed hit list and biggest coverage from a single bag.
This pick controls over 250 broadleaf weed types, including tough ones like dandelions, thistle, and poison ivy, which gives it a much longer reach than the typical lawn product. The fine particle size helps the granules hit individual weeds while feeding the grass around them, and users report that after applying this, their lawn looks noticeably greener and healthier within a couple of weeks. The 45 lb bag covers up to 15,000 sq ft, which makes it ideal for medium to large lawns that need a comprehensive solution in one application.
The nitrogen analysis of 21-0-3 provides a gradual, consistent nutrient release for up to three months, so you are not reapplying every few weeks. It cannot be used at the same time as seeding a new lawn, so plan your overseeding project separately. Buyers report that the product delivers on its promise of feeding the lawn while killing many weeds, though a strong minority experienced severe grass burn when following the standard instructions, suggesting meticulous spreader calibration is critical.
Weed control leader: Covers 15,000 sq ft and hits over 250 different weed types.
Major caution: A small but vocal group of owners mention the product killed desirable grass instead of just weeds, even when following the label exactly. Calibrate your spreader on pavement first.
Reach for this if: you have a large yard with a wide mix of broadleaf weeds and want one product that handles them all.
Look elsewhere if: you are new to lawn care or prefer a risk-free formula — start with a gentler product until you know your spreader’s output perfectly.
2. The Andersons Professional Surge Weed and Feed 16-0-9
Professional-grade weed control that works even in cooler spring and fall temps.
The analysis of 16-0-9 is formulated for post-emergent (applied after weeds sprout) weed control, meaning it hits actively growing weeds and feeds the grass to thicken over them. One reviewer noted that after switching from a popular brand to this product, the weeds died fast, while another reported no creeping charlie after a single season of use.
It eliminates over 250 common weeds including dandelions, clover, and plantain, matching the broad coverage of the Jonathan Green pick. Unlike some that struggle in temperature extremes, this performs throughout the growing season even in the cooler temperatures of spring and fall. Note that it is not for use on Floratam St. Augustine grass, dichondra, or lawns with desirable clover, and is not sold in New Hampshire or Washington.
What gives you the edge
- Covers 16,000 sq ft — 1,000 more than the Jonathan Green, 12,000 more than the Pennington.
- Professional-grade herbicide kills over 250 weed types including creeping charlie and crabgrass.
- Small particle design ensures better coverage per square inch.
Know before you drop it
- At 40 lb, the bag is heavy compared to smaller options.
- One reviewer felt there was no noticeable difference from cheaper brands, limiting the value at this price.
Best for: homeowners with a large lawn who want professional-grade results and can handle a heavier bag.
Watch out for: St. Augustine and dichondra lawns cannot use this, so check your grass type first.
3. Scotts Turf Builder Weed and Feed 3
Scotts’ most powerful weed and feed with a grip technology that holds onto hidden weeds.
This 43 lb bag covers 15,000 sq ft, putting it on par with the Jonathan Green product for coverage area, and it features Weedgrip Technology that grabs both visible weeds and the ones you have not spotted yet. The formula is designed to be up to twice as powerful for dandelion and clover control compared to the previous Scotts version. Reviewers report it killed all of the weeds, clover, and crabgrass in their lawns, though a separate buyer noted it did not handle crabgrass or clover well in their yard.
The active ingredients are 24-D and Mecoprop-p, a common herbicide combination for broadleaf weeds. One experienced reviewer shared a crucial tip: water your lawn first or apply after rain so the granules stick to wet weeds, then do not walk on the treated areas for 2-3 days to avoid burn spots. Unlike the Jonathan Green, this is also available as a hose-end sprayer version that covers about 6,000 sq ft per bottle, giving you application flexibility.
What stands out
- Weedgrip Technology helps control weeds you cannot see yet.
- Covers 15,000 sq ft, matching the Jonathan Green for large lawns.
- Available in both granular and sprayer formats for different preferences.
Things to keep in mind
- Not as effective on crabgrass or clover, according to some buyers.
- You must keep people and pets off the lawn for 2-3 days after application to avoid burn spots.
Choose this for: dandelion-heavy lawns where you want a proven brand with flexible application options.
skip it if: you are fighting a lot of crabgrass or clover — those weeds seem to resist this formula.
4. Pennington Full Season Weed & Feed with Crabgrass 25-0-8
A single-season formula that feeds slowly for months at a budget-friendly per-bag price.
Covering 4,000 sq ft from a 14.4 lb bag, this Pennington product covers 4,000 sq ft versus 15,000 sq ft for the Jonathan Green product, so it is designed for smaller lawns or targeted spot treatments. The 25-0-8 analysis provides high nitrogen, and it uses polymer-coated urea (a slow-release nitrogen source) that feeds your grass gradually for up to four months, meaning one application can last your entire growing season. One buyer mentioned that the product wiped out all the weeds in their lawn within two weeks of application, and it contains natural beneficial microorganisms to revitalize the soil.
It contains 5% iron for deep greening, which gives your grass a darker color. However, a cautionary review noted that directions for a Scotts spreader are incorrect in the instructions and led to severe grass burn, so you should test your spreader’s output on a small area first. This product is not available in Hawaii or South Dakota, so confirm availability for your state before purchasing.
What works
- Polymer-coated urea feeds your grass gradually for up to four months with one application.
- Contains 5% iron for a deep green color without extra steps.
- Natural beneficial microorganisms help revitalize tired soil.
What to watch for
- Only covers 4,000 sq ft — that is 11,000 sq ft less than the Jonathan Green product.
- Incorrect spreader settings for some brands can quickly burn your lawn.
Great for: smaller yards under 5,000 sq ft where you want a single-application season solution.
Avoid if: you have a large lawn or are not confident in your spreader calibration — the margin for error is narrow.
Understanding the Specs
Nitrogen Analysis (N-P-K)
The three numbers on the bag, like 21-0-3 or 25-0-8, represent the percentage of nitrogen, phosphorus, and potassium in the mix. The first number, nitrogen, is what greens up your grass and fuels leaf growth. Slow-release nitrogen, like the polymer-coated urea found in the Pennington product, feeds your lawn gradually instead of all at once, reducing the risk of burn and providing color for months instead of weeks.
Coverage Area
This is the total square footage one bag treats, and it is the most practical number to check. The Jonathan Green and Scotts products each cover 15,000 sq ft, while the Pennington covers only 4,000 sq ft. Always buy based on the square footage of your lawn, not the weight or size of the bag.
