Too Much Weed And Feed On The Lawn: How To Keep Things In Check

Lawn Care 101: How to Weed, Seed, Feed, Mow, & Water

This article is for informational purposes. Always seek the advice of qualified professionals.

Once I was crawling a gardening forum randomly, I found a fellow gardener to come up with the following query- I started noticing exceptional weed growth in my backyard. So, I bought weed and feed and applied it according to instructions.

After a while, I noticed dead spots in my yard. I could only narrow It down to exceeding use of weed and feed. What am I to do now?

Another gentleman from another part of the world writes- I didnt notice the amount of weed and feed I used in my lawn. After a few weeks, I found my grass was dying out. I noticed yellow dead spots.


Then, as I went to enquire about the packaging, I found that the area per feed was larger, 10000 Sq. feet to be exact. And I accidentally applied the whole pack on 2000 sq. feet of area. What should I do now?

We took a moment to realize- this is a problem that deserves a full-fledged discussion anyway. If youre one of those people who have faced a similar situation, then youre in luck. Because today, we will be discussing with you about the methods by which you can keep things in order.

When & How Often To Use Weed And Feed On The Grass

Most of them can be used every 6 to 8 weeks during the Spring, Summer and Autumn. Bear in mind though that because they have high levels of nitrogen in them, you may not want to apply the same weed and feed products all through the seasons.

Feeding your soil too much nitrogen can have drawbacks.

At best it will create excess thatch that will need scarifying and an overseed, to the worse end whereby it scorches the lawn and makes it look brown.


Some scorch though, may only be visible for a short time, like the next couple of mows after application.

Personally, I recommend using it once per year, when the weather is cool, wet and youre looking for growth. Other than that, its best to weed THEN feed with a fertiliser specific for the time of year needed.

When Should I Fertilize My Lawn In Spring And Fall

As well as knowing how often to apply fertilizer, its also key to know when to apply the fertilizer. To answer this question, it is recommended that you should always follow the instructions found on the label of your chosen fertilizer. However, following the general tips below will help you decide when to fertilize the lawn:

  • Apply when the grass is actively growing.
  • Apply when the soil is damp and the grass is dry.
  • Apply when the grass is frost-free.
  • Dont mow the lawn 3 days before or after applying the fertilizer.

Applying fertilizer outside of the period stated on the instructions as well as the guide above will run the risk of damaging your lawn so it is important to pay attention to this.

Dont apply fertilizers to your lawn during the winter months as the grass is dormant and will not achieve any better results. Applying fertilizer in the winter will increase the chance of polluting waterways by excessive run-off of the nutrients into nearby streams.

Problems With Using Weed And Feed

It can be tricky to get the timing right when you want to use weed and feed on your lawn. The grass might not benefit from a fertilizer at the time when the herbicide must be applied. In early spring, the right time to apply a pre-emergent herbicide, a dose of fertilizer encourages lush, green growth, but the grass benefits more from root development to help it grow well over the coming summer. Similarly, post-emergent herbicides are most effective if applied in late fall when broadleaf weeds are storing nutrients in their roots, yet a better time to apply fertilizer would be early or late summer.

8 Best Weed Killers for Lawn

The answer to this question depends on several factors. As a rule of thumb, fertilizing a lawn twice a year is sufficient when applying a fertilizer with a high nutrient content. The best advice is to choose a single supplier and product for that particular year/growing season and follow the instructions that they provide, paying attention to the recommended frequency of application. Some granular fertilizers will only require two applications per year, as they slowly release their nutritional value to the soil.

Soluble feeds can be applied from anywhere between every three weeks through to annual applications depending on the product chosen.


Working out how often to apply fertilizers is tricky, so we have created two tables below explaining how often to apply popular U.S. and U.K. fertilizers. The tables will help you choose which fertilizers are the best choice depending on what you are looking to achieve or which problems you are looking to overcome with your lawn.

What If You Apply Too Much Weed & Feed

The best way to avoid damaging your lawn is the flush out the weed & feed. Water your lawn with 1 to 2 inches of water for about 4 days. Dont apply any other weed & feed until the following year.

Planting Grass Seed Or Aerating After Weed And Feed

Weed& Feed prevents seed germination, so you should avoid planting new grass or aerating your lawn for at least four weeks. If you apply weed and feed in the spring and summer, spread new grass seed and aerate in the fall each year.


Reasons Weed & Feed Didnt Work

Remember to always follow the directions on the package. Always use a spreader to apply. Here are some common reasons why a weed & feed application could be ineffective:

  • Weed& feed targets broadleaf weeds like dandelions, and dollarweeds. It does nothing for crabgrass and other grassy weeds. For these, you should use a pre-emergent like Scotts Halts or Sta-Green Crab Ex crabgrass preventer in the early spring. Must be applied before weeds and crabgrass are growing.
  • Mature weeds are not actively growing, so the product will not be as effective. Weed and feed should be applied early in the growing season and a couple days after mowing.
  • Rain and sprinklers can wash away the granules. Make sure there is no rain in the forecast and avoid watering for two days after applying.

What if You Apply Too Much Weed & Feed?

The best way to avoid damaging your lawn after too much fertilizer application is to flush out the weed & feed. Water your lawn with 1 to 2 inches of water for about 4 days.

The Best Schedule For Applying Weed And Feed

Weed and feed is beneficial under the right circumstances but applying it too often can be disastrous for your lawn. We recommend only using it twice a year if needed, with the first application during April and another in October.

This gives all of the weed varieties a chance to start growing before you treat them.

If weeds arent actively growing on your lawn, using a standalone fertilizer will be a better approach. The weed and feed treatment can be harsh, due to the pesticides included in it, so if you can avoid using them, you should.

How To Apply Weed And Feed

Apply weed and feed when the temperature is below 80 F, but above freezing, a day or two after mowing the lawn to its normal height. A product containing a pre-emergent herbicide is applied to a dry lawn. If rain doesn’t fall within the following three days, irrigate the lawn thoroughly to activate the herbicide. A post-emergent weed and feed works best when applied to a wet lawn so that the granules stick to the weeds’ leaves. However, rainfall washes the granules off the leaves, so wait until no rain is forecast for several days and water your lawn before applying the product. To obtain an even distribution when applying weed and feed, use a lawn spreader. Don’t allow children or animals on the lawn while weed and feed granules remain visible to avoid contact with the herbicide.


Warning

Don’t apply weed and feed to a newly seeded lawn. Wait until the lawn has been mowed at least twice.

Avoid Treatment Of Broadleaf Weeds While Conditions Are Extremely Dry

Some of the broad-leaf weeds youll find on your lawns include- but not limited to:

  • Dandelions

Other broad-leafs weeds invade your gardens and have very fast-spreading mechanisms.

To keep their spread under control, you have two options:

  • One is the spraying of a broad-leaf organic weed-killing herbicide.
  • Second, the use of granular weed feed products.

Pro- Tip on timing:

Apply the granular feeds early on a morning with plenty of dew on the grass. In case you choose to use organic herbicides, look out for a day that is both warm and sunny.

Your best time for the application of either granular of sprays matters, and it best coincides with the optimal conditions for the chemicals eliminating the weeds to take effect.

For instance, granules work well with wet-dewy leaves. They require water for them to stick on the leaves of the weeds. So, when the grass is dry, and you proceed to apply them, you waste on the chemicals, and both time and money.

Regarding the warm sunny conditions for the spray-weed killers, the high temperatures provide optimum conditions for the absorption of the chemicals into the cells of the weeds.

The other tricky way around it is to water the lawn before applying the chemicals if you are on long-dry summers.

Here are some good broad leaf herbicides:

Weed And Feed Lawns: Where To Begin

Weed & Feed products combine a lawn fertilizer with a weed killer and/or weed preventer in one product. One application does double duty, treating random weeds spread across an entire lawn while also feeding and greening grass. Weed & Feeds come in two basic formulations, granules and liquids. But before you make an application, here are some things you need to know about weed & feed products.

Weed & Feed Starts With Weeding

The weed half of weed & feed contains some mix of herbicides to kill lawn weeds. Almost all products contain a post-emergent herbicide, but some also combine a pre-emergent herbicide designed to prevent new weeds from sprouting.

Post-Emergent herbicides kill existing lawn weeds like Dandelion, Clover and many other common weeds. The complete list of weeds can be found on your products label. These post-emergents are always selective herbicides, so they will not harm existing grass when applied as directed. New innovations, like BioAdvanced 5-in-1 Weed & Feed, also kill grassy weeds like Crabgrass, eliminating the need for multiple applications of additional herbicides to achieve control.

Pre-Emergent herbicides are meant to keep new weeds from germinating and growing. Timing is the key, apply too early and the preventer can become ineffective while weeds are still dormant. Apply too late and seeds may have already germinated. Youre probably most familiar with Crabgrass preventers that are applied in early spring.

And Ends With Feeding

Too Much Weed Control On Lawn: Gypsum And Cgm

Gypsum, although a very effective soil quality enhancer, has a couple of weak points. One of the weak points is that it plays a role in changing the soil chemistry completely.

So, though it brings back the surface to its original state, you shouldnt use it without a proper soil test.

As for CGM or Gluten meal, it can be an effective natural solution to fertilizer burn. But, due to the high cost and selective nature, its not the greatest alternatives out there.

When To Feed Your Lawn

In Canada, where cool-season grass types like Kentucky bluegrass, perennial ryegrass, and fescues are dominant, youll want to fertilize your lawn twice in the spring and once again in the fall. Each feeding should be spaced at least 6 to 8 weeks apart. If your cool-season lawn is still green and actively growing in the summer, you can continue to give it lawn fertilizer during the summer months . However, if your grass goes dormant during summer heat and drought, temporarily stop feeding until it greens up and starts to grow again in the early fall.

What’s In Weed And Feed

Because “weed and feed” is an umbrella term, there’s no one set list of ingredients for it. Not only is it sold in different forms , but it can also serve different purposes. If you’re trying to thwart weeds before they emerge, then you need a weed and feed that contains a pre-emergent herbicide. But if you need to kill weeds after the fact, the product to use is one with a post-emergent herbicide. The “feed” ingredients are not always exactly the same either. For example, the NPK ratio may vary .

But the typical bag of weed and feed with post-emergent herbicide contains:

  • 2, 4-D, dicamba, MCPP
  • Nitrogen, phosphorous, and potassium

  • Dithiopyr
  • Nitrogen, phosphorous, and potassium

Talking about safety, there are times when the neighbors CCTV cameras have you in their vision. This may be intentional or unintentional, so you may as well speak to them about it.
