When To Apply Lawn Weed Killer

How to Identify and Treat Weeds in 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

Pulling Weeds By Hand

Hand plucking is the easiest, cost-free and efficient method to prevent an infestation. Although not as convenient, this is without a doubt also the safest way to enjoy a weed-free lawn. While you may not be very excited about it at first, in time you may find out that this is actually beneficial for both you and your lawn. In fact, hand weeding is considered a stress-relieving activity by many gardeners.

It is important to take those weeds out the moment you see them grow. While it may be hard and it may take you more time, you have to be careful and take the whole weed out, roots and all. This will guarantee the efficiency of this method.

How To Treat Nutsedge:

To treat Nutsedge, you will need a particular herbicide, as Nutsedge is a sedge, so traditional broadleaf or grass chemicals will not work. We would recommend that you use a product containing halosulfuron or sulfentrazone for treating Nutsedge. Your lawn may need multiple treatments to eliminate this lawn weed. Nutsedge can be challenging to control, so it is best to treat your lawn from Nutsedge before it spreads. Fun Fact: Nutsedge can be easily spotted as it grows faster than typical lawn grass.

Identify And Treat Other Weed Types

After waiting for the second 2 week period after the second herbicide application, you then look to identify the remaining weed types.

If the remaining weeds are small in numbers, then the best option may be to spend a little time in pulling or digging them out.

However, if there are still a large number of unaffected and healthy weeds in the lawn, then it could be prudent to purchase a specific herbicide to kill them.

If youre well versed with weed types or are up for a bit of online research, this can be a very simple task. Otherwise, it would be wise to pull out some of the remaining weeds and take them to your local Nursery for identification, and a suitable weed killer purchased.

It is important to always identify weeds properly, buy the correct herbicide and always apply at the manufacturers specifications.

More On Annuals Vs Perennials

Eliminate Weeds from Your Yard

While fall is the best time to remove most weeds, not every weed should be treated in the same way.

Annuals. There are two different types of annuals, summer and winter. Winter annual weeds are just starting to sprout. Because they are still small, they are much easier to remove and treat right now, before they get big and grow deep roots. Summer annual weeds, on the other hand, should not be treated right now. Why? Summer annuals are already in decline, meaning any weed control treatment right now would be wasteful and ineffective. Instead, hand pull these and save your weed control for those tougher to remove perennial weeds.

Perennials. This category of weeds is kind of impressive in their ability to return year after year, regrow from root parts, and establish quickly. These characteristics also tend to mean they are tough to remove from your lawn if the entire root is not removed or if weed control is not timed correctly. However, fall is the best time to remove perennials. The plants are most vulnerable to spot treatment right now because as they send energy stores to roots, any spot treatment applications will kill above-ground tissue, reducing the amount of energy that can be stored in the roots over winter effectively killing the plant.

Why Lawn Weed Identification Is Important

Luckily, not all weeds cause harm to your plants, or your turfgrass.

Clover is a good example of this its a legume that actually turns air into Nitrogen and feeds the soil in your yard. But most people still want it gone from their lawns.

Yellow clover is an annual legume that acts in a similar way.

With so many different types of weeds knowing how to identify lawn weeds and combat each species in your yard is crucial if youre looking for a long-term fix.

Use the wrong product and you could end up killing your grass, not your weeds.

Killing Weeds With Vinegar

Vinegar can serve many purposes around the house. It is considered a toxic-free cleaning alternative and it can help you kill off the weeds in the lawn the same way it helps you remove germs.

Remember, though, that its best to stick to white vinegar, which is broadly distributed in stores. The most suitable product to help you get rid of weeds naturally should contain 3% to 5% acetic acid. Due to its acidic properties, though, it needs to be applied carefully and in the right manner, so it does not harm the soil.

Check also:

Stronger vinegar with up to 20 % acetic acid, also known as horticultural vinegar, is available, too. While you may be tempted to use it because it looks stronger and, therefore, should provide more effective weed control, better reconsider. It can be dangerous for both your health and the environment because of its corrosive power.

It is better to test with the less aggressive vinegar. And once you get it, here is what you have to do next:

Step 1: Get an empty and clean spray bottle.

Step 2: Pour the vinegar in. You can mix it with water or add soap, as vinegar and 1-2 tablespoons of dish soap could be an even more effective weed killer.

Step 3: Stir well until the ingredients blend.

Step 5: Check the results in a few hours and follow up with more spraying if needed.

Step 6: Remove the weed when its dead.

What Are Weeds And Why Are They A Problem

How to Treat Weeds in my Lawn

Before you can go to war with weeds, youve got to understand what they are, how they infiltrate your property, and what kind of damage they do.

Here are a few working definitions of a weed:

  • Any plant that grows out of place, or was not intentionally planted.
  • A plant that is competitive or that interferes negatively with human activity.
  • A plant that interferes with the activity of desired plants, flowers, or vegetables.

No matter how you define a weed, theyre strong competitors in the natural environment. Weeds reproduce rapidly due to factors like abundant seed production, long-term dormancy and survival of buried seeds, and their ability to occupy sites that cultivated plants wouldnt grow in.

Currently, there are an estimated 250,000 species of plants around the world, with about 8,000 behaving as weeds.

The most common weeds that affect homeowners in the US include the following:

  • Common lambsquarters

Here in California, the most common weeds are:

  • Grassy weeds such as annual ryegrass, blanket crabgrass, witchgrass, and creeping bentgrass.
  • Broadleaf weeds such as alligator weed, alsike clover, Asiatic hawksbeard, and annual sowthistle.

Left unchecked, these weeds can decimate lawns and gardens, choke out ornamental plants, act as hosts for pests and plant diseases, and negatively impact the appearance of your outdoor space.

Fortunately, the team here at Smiths knows how to tackle and eliminate all of these common weeds and more.

Weeds In Florida Have Unique Characteristics

Just like other plants, those we think of as weeds have distinctive characteristics and unique habits. In order to treat weeds effectively, its important to recognize some of those characteristics. Weeds are classified in a variety of ways, but essentially they are grouped into categories based on their growth habits, appearance, and life cycles.

Major categories of weeds include broadleaves that typically have net-like veins and showy flowers, grasses with rounded hollow stems, and sedges and rushes that thrive in moist habitats.

Weed life cycles can be annual, biennial, or perennial. Recognizing these characteristics will help to determine the proper control and treatment of the weeds in your landscape.

In all cases, healthy turf will minimize the presence of weeds, and treatment to prevent weed growth can be minimal.

With excessive winds and rainfalls, the soils of garden beds needs to be replenished. Whether the soil is your own creation or store bought you will need to remove existing soil from gardens. Remove a 2 to 3 inch band of soil from the base of established trees, shrubs, and perennial plants. A general rule of thumb is to remove 1/3 of your soil each year mixing with new soil in with the old. Careful mix these soils together without harming existing plant roots.

Once the soil is replaced you can mix in a granular pre-emergent herbicide. We recommend using a granular pre-emergent since it slowly releases nutrients over time to fight against weeds that not yet emerged. Products such as Barricade Granular Pre-Emergent Herbicide contains a granule formulation to continue to eliminate various broadleaf and grassy weeds for up to 60 days.

Apply 2.5 to 5.94 lbs. of Barricade Granular Pre-Emergent Herbicide per 1,000 sq. ft. of ornamentals. Broadcast the products granules with a hand spreader or broadcast spreader depending on the size of the garden. Once applied, active Barricade Granular Pre-Emergent Herbicide with 0.5 inches of water.
