Planting Grass Seed Or Aerating After Weed And Feed

The Benefits of Feeding The Lawn

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. It would be best not to apply any other weed & feed fertilizer until the following year. Unfortunately, over watering can create run-off in certain drainage situations, so be aware of your location and where the water is going.

How To Spread Weed & Feed

There are a few important details to remember when spreading weed & feed. Keep all of these in mind when planning the job to achieve the best results. Note that these tips are not intended to replace manufacturers instructions, though you will find most manufacturers will recommend some variation of these tips.

Here Are 8 Reasons You Shouldnt Use Weed

6. You dont 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, doesnt 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 wouldnt use the products on my own yard, around my own children, then I wont 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.

How Often Should I Weed And Feed My Lawn Uk

In general, I advise doing five treatments each year to a lawn that is somewhat healthy, has an average amount of foot activity, does not have any dogs, receives a lot of sunlight, and has rich, nutritious soil. Each one adapted to the specific requirements of the lawn as well as those that change with the seasons.

When To Water After Applying Weed And Feed Fertilizer Application


With a granular post emergent product, it is important to not water for at least 24 hours after application. The reason for this is that you need the product to stay in contact with the leaves of the weeds to be most efficient.

It goes without saying that if you water too soon after you apply weed and feed, you will wash it off before it starts working.

Since no two products are built exactly the same, you should refer to manufacturers usage guidelines.

Some pre-emergent products can be watered in, so that the active ingredient is absorbed by the roots.

If youre applying a liquid weed and feed product such as Scotts Liquid Turf Builder, you dont need to water the lawn after application, since both the fertilizer and herbicide are already in liquid form. The nitrogen acts as the fertilizer, and gives your lawn a boost, while the herbicide kills weeds such as ground ivy, chickweed, and buckhorn.

Make sure to check the weather forecast for your area before carrying out your weed feed exercise.

If you can afford the irrigation system cost, dont forget to turn off that zone or zones for 24 hours after, and remember to turn it back on again afterwards!

Control Crab Grass With A Crab Grass Preventer In The Spring

  • Apply a crab grass pre-emergence preventer between the first and third mowings in the spring.
  • Preventers usually come as granules that you put on the lawn with a spreader.
  • Make notes in the fall about where your crab grass seems to thrive and treat those areas in the spring.
  • Once crab grass shows up in your lawn, you have three options:
  • Hand-pull the clumps to prevent the plant from reseeding itself.
  • Let the crab grass go until the following spring and then use a preventer at the right time.
  • Treat clumps with a post-emergence crab grass killer.

Weed, Feed & Green your lawn

You will only kill weeds when they are actively growing. This means commencing sometime in May and finishing sometime in late September or early October.

I would not rush to apply lawn weed killer to the whole lawn in the early spring as there will be a lot of weeds that wont surface until later on. In early spring just spot or hand weed. For a good weed kill over a broad range of weeds in your lawn try starting in May. If you need to repeat the treatment you still have plenty of time before cold weather makes it impractical. Read the label of your weed killer to make sure repeat treatments are allowed.

A well fertilised lawn will help you get the most from your weed killer. In spring apply fertiliser in April and weed kill end of May or early June. In autumn feed 7-10 days before weed spraying.

One of my favourite times for complete lawn weed control is in late August or September whilst there is still some warmth around. I would recommend this if you just need the one application in the year. The reason for this is:

  • Most weed types are still around
  • The spring seeds in your lawn will have germinated so you get those as well
  • Killing weeds in autumn is easier than killing winter hardened weeds in spring
  • Youll have a weed free lawn until the next round of weed seeds germinate the following spring

Typically, it will all depend on the type of weed and feed that you have. The reason behind this is because each manufacturer have different labels and they have different suggestions for lawn owners today.

There are manufacturers who are recommending a treatment of the lawn once every year. But if you are planning to use the weed and feeder to treat your entire lawn, then it would be best to use it twice, and you need to explicitly clarify it on the label of the weed and feed that you have purchased.

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.


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