Weed & Feed products are lawn fertilizers that also include weed killers and/or weed preventatives. One treatment treats random weeds that have grown across an entire lawn and also feeds and greens the grass. Weed & Feeds are available in two fundamental forms, granules and liquids.
- However, before you apply, there are a few things you should know about weed & feed goods.
- Weeding and Feeding Begin with Weeding The “weed” portion of “weed & feed” contains pesticides to eliminate grass weeds.
- Almost every product contains a post-emergent herbicide, but some also include a pre-emergent herbicide meant to inhibit the germination of new weeds.
Post-emergence herbicides eliminate existing lawn weeds such as dandelions, clover, and many more. The whole list of weeds may be found on the label of your product. When used as prescribed, these post-emergence herbicides are always selective, so they will not harm existing grass.
New developments, such as BioAdvanced 5-in-1 Weed & Feed, eliminate the need for several treatments of additional herbicides to control grassy weeds like Crabgrass. Pre-emergent herbicides are designed to prevent the germination and growth of new weeds. Timing is crucial; if the herbicide is applied too early, it may become ineffective while the weeds are still latent.
If seeds are applied too late, they may have already germinated. You are most likely familiar with crabgrass preventatives used in early spring. And Terminates in Feeding The “feed” portion of “weed & feed” refers exclusively to fertilizer. Most fertilizers include various levels of nitrogen, other macronutrients, and occasionally micronutrients.
- Nitrogen (N) is the most essential component of lawn fertilizers and is available in two main forms: fast-release and slow-release.
- The majority of lawn fertilizers contain a combination of fast-release and slow-release forms for rapid greening and maintained development.
- Fast-Release Nitrogen, such as urea and ammonium sulfate, is easily accessible and rapidly absorbed by grass, resulting in rapid greening.
Unfortunately, it may also burn your grass if poorly sprayed, and it can seep through the root zone or wash off the lawn after heavy rain, producing pollution. Slow-Release Nitrogen (also referred to as WIN or water-insoluble nitrogen), such as sulfur-coated urea, methylene urea, and animal manures, is released more slowly to the grass, resulting in more sustained, uniform growth – up to three months for methylene urea.
- Before Beginning, Determine Your Lawn Type Before applying any weed-and-feed or fertilizer product, you must determine your grass type.
- Some fertilizers may be used on all types of lawns, but the majority of weed & feed solutions are designated especially for different species of grasses.
- Applying the wrong product to the wrong type of grass might result in lawn damage.
Use cautious and carefully read the product’s label. If you are still unsure, contact the manufacturer at the toll-free number listed on the label. When To Apply Weed & Feed products are most effective in the spring and fall, when weeds are tiny and actively developing.
Wait until you’ve mowed your grass twice in the spring before applying to ensure that it has emerged from dormancy. Check with your local Cooperative Extension System office in the fall for historical frost dates in your region. Based on this date, many Weed & Feed labels will prescribe application time.
Also, the majority of weed and feed products have temperature limits; check the label. Do not apply to soils that are saturated with water, stressed by drought, disease, or injury susceptibility. Methods for Applying For liquid weed & feed products, be sure to use one of the sprayer types specified on the package and to follow the mixing and spraying directions on the label.
- Use a rotary or drop-type spreader for granular weed and feeding.
- Drop spreaders distribute fertilizer in a small band right below the spreader, whereas rotary spreaders cover a larger area.
- The application design pattern is crucial.
- Be sure to follow the directions on the label.
- The application parameters for both types of spreaders are customizable.
Depending on the spreader’s settings, the amount of fertilizer applied will vary. Before fertilizing, consult the spreader manufacturer’s instructions to calibrate your equipment and guarantee optimum application rates. On the fertilizer’s label, you will discover the correct settings for your type of spreader.
- If not, a toll-free phone number should be provided.
- Do not use the spreader until you are confident that it is correctly adjusted.
- You may learn more about spreader calibration and spreader settings.
- Always read labels and adhere to their recommendations.
- Other Important Information Mowing — For optimal effects, mow your grass one to two days before to application.
You should leave the clippings from your next three mowings on the grass. Avoid using these clippings as mulch or compost around decorative plants, trees, or vegetable gardens. Do Not Rake – Excessive raking will disrupt the weed-prevention barrier and impair the efficacy of this product.
Many weed and feed solutions require that you wait 24 hours before watering in. Consult the label on your individual product. Feeding New Lawns — Most new lawns do not require fertilization until six to eight weeks following planting. Nonetheless, this might vary based on how the soil was prepared before to planting and the type of fertilizer utilized.
Consult your local office of the Cooperative Extension System or nursery for advice on fertilizing new lawns.
When is the optimal time to use weed killer?
What is the optimal season for using weed killer? Spring is the greatest season to apply weed killer, followed by Fall. Spring is a good time for preventing weeds from growing by capturing them during their pre-growth period. Fall is equally beneficial since weeds are at their most susceptible just before winter.
Do You Cut the Grass and Weeds Prior to Using Weed & Feed? By Sara DeBerry Updated on November 28 Most retailers refer to the application of a pesticide and fertilizer combination as “weed and feed” Weed and feed may be an efficient and straightforward method for establishing a strong grass and a healthy-looking yard.
- Each weed and feed product may have various instructions, and it is essential to carefully follow the label’s recommendations.
- Off-label applications, such as raising the concentration or treatment rate beyond the guidelines on the label, may not only be detrimental to your lawn, but also unlawful.
- It is advised that you mow the lawn a few days prior to applying weed and feed and wait a few days following application before mowing again.
This ensures that the herbicide – the “weed” component of “weed and feed” – has sufficient time to be absorbed by the leaves of the weeds and begin to have its effect. It is possible to combat weeds by mowing height, but a delicate balance must be maintained between preventing weeds from going to seed and cutting the grass too short.
When using a mower deck height that is too high, weeds may develop and produce seeds. In contrast, if you set the mowing height too low, you will harm and weaken the turf, creating openings for new weeds to invade the yard. Use the cutting height suggested by your local extension agent for the type of grass you have.
If you have a serious weed infestation and seed heads are beginning to appear in your yard, try bagging your clippings to prevent the spread of seeds before applying a weed and feed. Leave the clippings on the grass the next time you mow the lawn after treatment.
They will aid in mulching the turf, and the remaining weed and feed granules will be spread throughout the mowing area. The same holds true for clippings treated with a liquid; plant material containing residual chemicals will decompose and release them back into the soil. Weed and feed treatments to a whole yard are only required if the entire yard contains weeds.
If the weeds are only present in certain locations, such as around gutters or beneath trees, use a fertilizer that does not include a herbicide and treat the problem weed areas individually with the appropriate herbicide. Contact your local extension agent for assistance identifying weed species.
Other lawn issues, such as insect damage, over- or under-watering, and animal damage, can also weaken your grass and make it susceptible to weed infestation. Look for big patches of discolouration, grass that is dead or withering, or thin spots. One of them might be an insect or fungal signal. Utilize the website of your local extension office to determine your lawn’s unique concerns, and then address them accordingly.
You may discover that by just watering your grass less, you can inhibit the growth of weeds or fungi. A good grass is dense, and weeds have difficulty growing in dense lawns. Do You Cut the Grass and Weeds Prior to Using Weed & Feed?

Estoy de Acuerdo / I agree Collapse My yard is beginning to show signs of life as a result of the recent mild weather. In addition, I am beginning to receive calls from homeowners with inquiries on weed and feed fertilizers and the optimal time to apply them to the grass.
The answer is dependent on the sort of weed-and-feed fertilizer that you purchase. Fertilizers containing weed killers are classified as either pre-emergent or post-emergent. Pre-emergence herbicides, as their name implies, inhibit the germination of weed seeds. It is crucial that pre-emergence herbicides be sprayed before to the germination of weed seeds.
Now (early spring) is the time to use the herbicide and fertilizer if you wish to control a large number of summer weeds. The exception would be if crabgrass management was desired. Mid-April is too late to apply fertilizer to cool-season lawns while crabgrass preventative is being treated.
The majority of weed-and-feed fertilizers sold now contain a post-emergence weed killer. For these herbicides to be effective, the weed must be actively growing at the time of treatment. If you use a post-emergent herbicide and fertilizer at this time, you will only kill weeds that are now growing, but it will have no effect on weeds that emerge later.
By the time summer weeds appear in the lawn, it will be too late to apply a weed and feed, as it is not suggested to fertilize cool-season lawns in the summer. Post-emergent herbicides and fertilizers can potentially harm established ornamentals if administered improperly, such as at temperatures exceeding 90 degrees Fahrenheit.
Is liquid fertilizer and herbicide superior to granular?
Both liquid and granular weed control treatments are easily available to homeowners and professionals alike. Although there may be differences between professional and consumer treatments, the majority of granular and liquid weed control agents have the capacity to eliminate the entire plant, including its roots.
- Granular weed control may be the solution if you’re seeking for a simple DIY technique to manage weeds in your lawn and don’t mind waiting till the lawn is moist to apply the product.
- Liquid weed control is the product of choice for the majority of professional lawn care services.
- It controls a range of weeds efficiently and rapidly.
According to Purdue University Turfgrass Science, liquid sprays are more effective than granular formulations because the liquid formulation is sprayed across the leaf surface of the weed and does not require extra moisture to adhere to the leaf. Once the liquid has dried, it will remain on the leaf surface even if it rains.
