When Best To Apply Weed And Feed To Your Lawn?
For you to get the most from your 2-in-1 weed and feed product for your lawn it is essential to get the timing right. As a general rule, you should apply the product during the active gardening season from April to August.
If it’s too early, the weeds are just developing and you may not catch all of them. Also, consider how the fertilizer works. Fertilizer supports healthy grass growth and improves its foliage as well as the grass root network.
Applying the weed and feed too early can lead to much more top growth while limiting the root production. This means the grass is weaker and you would have to mow your lawn more often.
Lawncare In Spring
For feeding your lawn in spring it’s best to use a weed and feed to control any moss growth and also helps your grass to grow stronger, plus it also kills off all the common weeds.
When the moss and weeds are under control later in the spring, you can move on to a general lawn feed that helps to keep your grass looking thick and lush.
The best for this is liquid lawn feed as you can use them with a hose pipe and they water the lawn at the same time.
Lawncare In Summer
If it’s a hot summer, the grass of your lawn stops growing and it does not use any feed.
During dry periods lawns start to get stressed and could be damaged if you apply weed killer or fertilizer. Try not to feed your lawn during hot spells, instead wait until it has rained and allow the water to soak in for a few days.
Then you can start applying lawn fertilizer again in 6-8 weeks intervals across the summer.
Lawncare In Fall
There are some good weed and feed products available particularly for fall. At this time of year, your grass will need a slightly different fertilizer as it grows at a slower rate and it prepares the lawn for winter by growing stronger roots that can withstand the cold.
Lawn weed and feeds designed specifically for fall have a low nitrogen content as they don’t want to encourage foliage growth, which could be easily burnt by frost.
Feeding your lawn in fall can encourage strong root growth so that the lawn can recover again quickly from the cold winter.
Keeping your weeds out of your lawn is a continued struggle throughout the year but if you follow the instructions on your weed and feed product then you will have the exact details on when best to apply it.
How Does Weed And Feed For Your Lawn Work?
Weed and feed products work in either of two ways. Some prevent the weed’s protein product by blocking photosynthesis, others damage the root of the weed so that it dies off.
At the same time, the fertilizer encourages healthy grass blade growth that leads to better lawn density. The denser and thicker your lawn is, the fewer weeds can germinate and grow as the grass crowds out the competing weeds.
When it comes to applying weed and feed the timing is everything. If you apply the product at the wrong time of year you may get inconsistent or poor results, or you could even damage your lawn.
When You Apply Weed And Feed Too Early
If you apply weed and feed too early in the season, the grass of your lawn may get much more fertilizer than it really needs and this can lead to fertilizer scorch.
The majority of grass types will need more nutrients while they actively grow from mid-spring onwards.
For this reason, weed and feed has been designed to release nutrients slowly. This means when you apply it around April time, it will support grass growth right at the time your lawn needs nutrients.
When You Apply Weed And Feed Too Late
If you opt to apply weed and feed later in the season, for example, in September, it reduces the effectiveness of the treatment.
While September is a good time to kill and treat weeds, it’s not the best time to apply fertilizer to the grass as this would fuel top foliage growth.
This also leads to weaker roots over winter. However, if you want to get rid of your weeds in the second half of the year you are better off by using a stand-alone weedkiller for lawns in September, and then apply a separate lawn fertilizer in October.
How Long Does Weed And Feed Take To Work?
Depending on your grass and weed type, and your chosen product, it can take between 4 days and one month to see any visible results.
The first thing you’ll notice is that moss, dandelion, clover and other weeds turn brown or black, and die off.
How Long Does Weed And Feed Last?
Most weed and feed products come with their own recommendations on how long they can last.
Generally, weed and feed can be applied either once, twice or regularly throughout the growing season. This depends on your chosen product.
Different Types Of Weed And Feed
Weed and feed comes in two forms, granular and liquid. Both these products are very effective at killing weeds and fertilizing your lawn. Each has slightly different properties so they lend themselves for different lawn and weed types.
Pre-Emergent And Post-Emergent Weed And Feed
In addition to the different form weed and feed (granules or liquid) comes in, there are two types of weed and feed: pre-emergent and post-emergent weed and feed. For the omptimum results you need to know what type you want for your lawn.
Pre-Emergent Weed And Feed
Pre-emergent herbicides kill weeds before they grow, so you can apply pre-emergent weed and feed on established lawns where weeds are already under control.
Pre-emergent weed and feed is ideal to eliminate stubborn crabgrass and Japanese stilt grass.
However, even if you completely removed the weeds the previous year, they could still return as weed seeds fly through the air and settle on the lawn.
For this reason, you should apply the product in early spring each year to prevent weeds from growing.
Post-Emergent Weed And Feed
Post-emergent weed and feed kills weeds that are already grown. You can choose the frequency of how often you apply the product depending on how bad the weed growth is in your yard.
You can use post-emergent herbicides for the removal of bermudagrass and nimblewill.
However, if your lawn has too many weeds, it might choke the grass and you need to check with a landscaper or gardener for more advice.
Liquid Weed And Feed
Liquid weed and feed is applied by using a spray, either as a concentrate diluted with water. For this, you need to use your own garden sprayer to apply it.
Alternatively, some products also come in a convenient hand-held sprayer that is easier to use for smaller areas.
The advantage of liquid weed and feed is that you can apply it to patches or specific areas of your lawn. It acts fast and there is no need to water the lawn before or after application.
Granular Weed And Feed
If you have larger areas of lawn, then granular weed and feed is the better option. You will need to pre-water your lawn and then use a drop spreader to apply the product. This allows for a more consistent spread across the lawn.
Granular weed and feed are better value for money. They are also designed with a slow-release formula, which means nutrients are released into the lawn over time, so you don’t have to apply the treatment to your lawn as often.
Weed And Feed Safe For Family And Pets
For all families and pet owners, the safety of any weed and feed product is essential, especially when you spend a lot of time in your garden. Manufacturers have created products with this in mind.
The majority of weed and feed products state on the label that you should keep children and pets away from the treated lawn for at least 24 hours after application.
This is either because the weed and feed could stain surfaces which could ruin clothes and shoes, especially for children and pets that could pick the material up. Or the product contains hazardous ingredients that are dangerous if consumed.
Please read the product label and the manufacturer’s guidelines carefully so you can make sure that your family and pet are safe.
Organic Weed And Feed
True organic weed and feed products are difficult to find, and even if they are labeled as organic, they may prove to be not as effective as a standard synthetic weed and feed.
The primary ingredient of most organic weed and feed is corn gluten meal which is safe when you come into contact with it. This makes them more child and pet friendly.

How To Apply Weed And Feed
Each weed and feed product has its own application instructions that should be followed for safety and best results. However, there are some basic rules:
Mowing And Watering
It’s a good idea to mow and water the lawn two days before you apply the weed and feed. This ensures that the granules are evenly distributed in the wet lawn.
Too much rain and too much heat can affect your lawn’s tolerance to the weed and feed so it’s important to choose a day when it’s dry and temperatures are higher than freezing but below 80 degrees Fahrenheit.
Avoid Heavy Rain
It’s essential that you don’t apply your weed and feed product immediately after heavy rain as it can wash out the nutrients.
Use A Spreader For Granules
If you are using a granular weed and feed you need to use a drop or rotary spreader to apply the granules onto your lawn evenly. Cover the area by walking back and forth across the lawn, with overlapping stripes.
Use A Garden Hose For Liquid Weed And Feed
With most liquid weed and feeds you can attach a hose pipe to the sprayer. Then apply the product as instructed on the label.
Carefully Follow Instructions
For the best results and to make sure you get the most out of your weed and feed product, it’s important that you carefully follow the directions on the label. This will prevent any accidents and also avoids burning your grass.
Frequently Asked Questions
Should I Use Weed And Feed?
You can apply pre-emergent weed & feed to kill weeds before they start to grow.
For the best results, you should apply weed and feed in spring each year. This prevents common weeds, like dandelion, crabgrass and Japanese stilt grass, from returning.
Bear in mind that even if you completely killed the weeds the year before, they may still return because weed seeds are carried across your lawn by air.
That’s why it is a good idea to treat your lawn annually with pre-emergent weed and feed.
Should I Water After Weed And Feed?
Some lawn weed and feeds require you to water the lawn straight after application, while others instruct you to only water after 24 hours. For these, make sure that there is no rain in the next day after application.
If it does not rain in the days after, you should water the lawn properly to work the fertilizer in.
Can I Weed And Feed In The Fall?
Ideally, you should apply weed and feed in the spring after weeds begin to pop up but if you need to apply weed and feed to your lawn a second time, it’s best to wait until fall so your lawn has time to recover before the fall.
There are also special weed and feed products designed for use in the fall to strengthen your grass before the winter, so it looks lush and green in the next spring.
Should I Mow My Lawn Before Using Weed And Feed?
Most products label clearly on their instructions whether you need to mow your lawn before using weed and feed.

How Do The Seasons Affect The Use Of Weed And Feed?
