8 Reasons Weed-‘N’-Feed May Not Be Right for You
Now that the weather is warming up, outdoor activities are gearing up, and you’re finally looking at your lawn. Homeowners may be tempted to run to their local lawn and garden store to pick up a bag of Weed-n-Feed. Many “experts” will tell you that this is the best way for homeowners to control weeds and fertilize for “season long control”.
The reality is, you will pay top dollar for a subpar product. Once you factor in the product costs and your time, it will be less expensive in the long run to hire a professional that is certified in lawn weed control and fertilization. Personal Lawn Care, Inc. provides three weed control and three fertilization applications with free touch-ups throughout the season. Our program provides true “Weed-n-Feed” for your lawn.
Here are 8 reasons you shouldn’t use Weed-n-Feed
1 Wrong Amount: One of the reasons most homeowner are unhappy with their Weed-n-Feed application is due to an improper rate of application. If you apply the product too thin, the weeds will be able to break through; too heavy and you risk burning your lawn or stressing it out. Sometimes the product itself is poorly formulated or simply too strong for your lawn.
2. Bad Timing: There is a small window of time (usually 6-12 weeks) where you can control spring weeds. If you have a hard time fitting lawn care into your schedule (like most homeowners) and it creeps into May or June before you apply Weed-n-Feed products, they will at the least be ineffective and at most damage your lawn. Unfortunately your local lawn and garden center will sell Weed-n-Feed products well into the summer.
3. You don’t water it in: There are two irrigation aspects that must be met when using Weed-n-Feed products. First, the leaves of the weeds must be wet before the product is applied. To take care of the weeds that have already germinated, the product must stick to the leaves. Then, about 24hr later it must be watered in. The product has to soak into the soil to work on germinating weeds. Products that your local lawn professional apply soaks deeper into the soil preventing germination. Basically knocking out those weeds before they have a chance.
4. The product doesn’t cover all weeds: Even though the Weed-n-Feed you get at your local lawn and garden center says it covers a broad spectrum of weeds, they may be overselling their product. Most of their products are sold nationwide. It is impossible for one product to cover every weed eventuality. Personal Lawn Care tailors the products applied to meet your specific weed control needs. This provides targeted control for even the hardiest of weeds.
5. Won’t prevent weeds in the future: Just because your Weed-n-Feed takes care of your dandelions now, it may not take care of the crabgrass that springs up a week later. There may be products that last longer, but for better control, contact your local lawn care professional.
6. You don’t know how safe the product is: There is a lot of debate about products used for weed control. The Weed-n-Feed products available may contain any number of chemicals. Just because the Department of Agriculture approves a product to be used on your lawn, doesn’t mean that it is safe for you, your children, or your pets. Over the past 30 years, Cullen Beard, owner of Personal Lawn Care, has taken great care in choosing which products are applied to your lawn. His background as a science and chemistry teacher makes him qualified to research the products in depth. “If I wouldn’t use the products on my own yard, around my own children, then I won’t use it on yours”.
7. Too much Nitrogen: The “feed” part of Weed-n-Feed products is usually a high nitrogen fertilizer. High nitrogen fertilizers should only be used during the summer when the lawn has come completely out of dormancy. Providing your lawn with too much nitrogen too early in the season will weaken root growth thereby making it more susceptible to drought or other stresses. Cullen recommends a high phosphorous fertilizer in the spring followed by a high nitrogen fertilizer during the summer.
8. Can interfere with seeding: If you are planning to seed your lawn, Weed-n-Feed will stop you in your tracks. Because Weed-n-Feed kills the weeds as they are germinating, it will also kill your delicate grass shoots. If you are planning on seeding, you should refrain from using any pre-emergent weed control until the new grass is well established.

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.
