Whole Lawn Or Spot Treatment

Does Weed Control Affect Grass Seed?
  • If the weeds are sparse or limited to certain areas of the lawn it is not necessary to spray the whole lawn you can spot spray the weeds or only spray the affected areas.
  • Coarse grasses can also be a weed in fine turf lawns. The broadleaf weed killers will have little effect on these and spot treatment with Weed Weapon Invade Gel is the best option. Apply the gel to the central growing crowns of the coarse grass.

Treat Those Weeds First

If you want to improve your lawns appearance, then you will need a weed control product and fertilizer. However, you need to apply these products in a specific order. The first course of action should be to use a safe herbicide to get rid of those weeds. Not only are weeds unsightly, but they can steal nutrients and water from your grass. The roots of the weeds will also compete for space in the first few inches of your soil, and they can effectively choke the grass and plant roots. As you can tell, it is vital to get rid of those weeds in your first step.

For those bare spots in your yard, you will want to till those spaces to help bring any weed seeds to the surface. A preemergent herbicide can be applied to the soil. Before you start adding fertilizer to your grass, you should wait at least a week. This period will give your grass a chance to absorb the weed control product. After a week, you can reseed your lawn with the appropriate grass species. In many cases, those palm-sized bare spots will fill in naturally. If there are still weeds poking through after a herbicide application, you might want to choose a glyphosate product to prevent further weeds in your yard.

What Is The Best Time To Kill Weeds

Its true that weeds are a year-long battle that we all fight, but planning ahead can help you control them more effectively. Many experts suggest that the best time to spray weed killer is in the warmer months because the chemicals arent as effective if theyre allowed to freeze. However, this doesnt mean that weed killer will be equally effective during any warm season.

Weedkiller works by interfering with the growth of weeds. It blocks their ability to produce protein as well as the development of roots. This is why the summer isnt the best time to apply weed killer, as the weeds will most likely already be growing and germinating.

Aim to spray your weed killer during the spring when its warm and the weeds are just beginning to grow. You can also apply the weed killer during the fall in October, as the weeds will be the most vulnerable. If the weeds dont die immediately, you can wait till the spring to reapply the treatments.

How To Time Pre

Pre-emergent herbicides only kill weed seeds as they sprout. It will not kill dormant seeds or sprouted weeds. Because of this, its important to spread pre-emergent shortly before weeds begin to sprout.

Spring weeds sprout when soil temperatures rise to 55 after winter lows. Fall weeds sprout when the soil temperature drops down to 70 after summer peaks. Because Texas climate differs from region to region, the best time to apply pre-emergent to your Texas lawn depends on soil temperatures in your region.

Helpful Tips For Lawn Weed Control In The Fall

If youre thinking about how to get rid of weeds in your lawn during the fall, here are some tips to keep in mind:

1. October is the best time

The ideal time for lawn weed control service is anytime in the month of October. Its best to do two applications that are applied two weeks apart. During this time, the weeds are fully in food storage mode thats needed for surviving in the winter. Taking weed control measures during this time will hinder this process.

2. Granules or liquid

When it comes to common weeds, granule applications may be most suitable. However, the weeds that are the most difficult to kill should be treated using a liquid herbicide.

3. Seeding

If youve seeded your lawn in the fall, make sure that you avoid the seeded areas, or spot-treat the larger weeds while avoiding spraying on the seeded regions around the weed. Weed killers can also kill young seedlings and seeds.

4. Fertilizing

The best way for lawn weed control is to maintain a thick, healthy lawn. Fertilization, especially in the autumn, is quite effective and can help you in this regard. Apply quality lawn food anytime in the months of October and November. The best time for fertilizer application is when youve just mowed the lawn.

Applying Weed Killer To A New Lawn

New lawns are more sensitive to herbicides than established lawns. Don’t apply pre-emergent weed killer to a newly seeded lawn. When the grass has an established root system, you can safely apply a pre-emergent herbicide product that contains dinitroaniline. Additionally, in spring, you can apply a product that contains pendimethalin to a lawn that was seeded in fall, after the lawn has been mowed four times.

When applying a post-emergent herbicide to a new lawn, again, wait until the lawn has been mowed four times. If the lawn is newly sprigged, wait until the sprigs are rooted and growing. Apply the weed killer at half the rate recommended on the label, and reapply the product seven to 10 days later to treat weeds that may have survived the first application.

How To Apply Weed Killer

Even if you select the right weed killer, applying it incorrectly can make your efforts fruitless, and the wrong application can cause complications.

Many weed killers need to be diluted with water and put in a spray bottle. The products label will explain precisely how much water and weed killer youll need to combine. Some weed killers, however, come in granular form. Solid weed killers must be applied with a spreader.

When applying weed killer, timing is everything. You dont want to apply weed killer immediately after mowing your lawn since that could harm your tender grass. The same goes for fertilizer. In both cases, wait several days before applying weed killer.

The weather also plays a role in when to apply weed killer. Applying weed killer when its too hot can stress your grass, and applying it right too soon before it rains means it can wash away before it gets absorbed.

Safety Issues Around The Home

Not only should we protect ourselves when spraying weed killer by wearing long sleeves, gloves and goggles, as well as using a respirator and protective headgear, but we should protect others. We need to read the label to know how long we must stay out of the treated area, but before that, we need to keep pets indoors. Also, we need to keep children away from the sprayed area before and after, so they should be inside during the spraying and avoid the area for the duration specified on the label.

Best Time To Apply Liquid Weed Killer

Apply the weed killer when you have at least two inches of new growing weeds. When they are actively growing, commencing sometime in April and finishing sometime in late September or early October. A lawn owner should have to choose the best weather and the best application timing to get the best result, so proper timing and clear weather are essential to avoid wasting your time.

Usually, a weed killer works best when the weather is dry but is too hot for several days. When it is monsoon season and the rainwater, even a light shower can wash out the herbicides from the upper surface that need to treat and can ruin your efforts. There will be a residual effect of herbicides that will get diluted by the rain.

Another factor is the wind, mainly when you apply glyphosate or similar non-selective herbicides. It can cause the killing of all other plants such as vegetation, flower, or vegetable which came in contact with it. Wind can cause a more expansive space of spraying chemicals onto the different areas of land, which can severely kill the desirable plants.

Why Do Most People Prefer Applying A Weed Killer In Late August Or Early September

Ortho® WeedClear Weed Killer for Lawns Concentrate

Late August or September, while there is still some warmth around, is one of the gardeners favorite times for full lawn weed control. If you only need one application per year, this is the time period to consider.

Why and how to apply a weed killer in late August:

  • Most weeds are already grown completely
  • The spring seeds in the lawn are already germinated by this time
  • Easier to kill than winter-hardened weeds in early spring
  • The lawn should be fertilized before the application to improve its effect
  • When there is moisture in the topsoil. Otherwise, you may harm the grass
  • When it is going to rain for 6 hours
  • Wet grass may dilute the weed killer, so apply only on dry grass
  • It is recommended to apply only in calm weather. Otherwise, wind may blow the substance away
  • Do not spread the weed killer in freezing conditions
  • Avoid extreme heat and strong sunshine
  • During the late summer, it is better to use a weed killer in the cooler evenings
  • Consider applying a weed killer after mowing. You should wait for 2 days if you intend to apply a liquid herbicide. After the application, do not mow for the next 3 days

How Often Can You Apply Pre

You can apply a pre-emergent weed killer up to twice a year. If timed correctly, one application in spring and one application in fall should control the vast majority of weeds year-round.

If you live in a region with aggressive late-growing summer weeds , then you can apply a second round of pre-emergent 8 weeks after your spring application. This application schedule should not cause any harm to your yard.

Weed Killer Or Fertilizer First

Weeds need the same things lawn grass needs to thrive, i.e. sunlight, water, and nutrients. Unfortunately, weeds can still thrive even when the grass is struggling from soil compaction, lack of enough nutrients, or less water.

Most weeds are deep-rooted and grow quickly, and they will choke lawn grass if left on the lawn and therefore should be eliminated for the grass to thrive. But should you kill the weeds or fertilize the lawn first?

As a thumb rule, you should kill weeds first, and then wait for 10 14 days before fertilizing the lawn.

  • Roundup and other Contact Weed Killers: Contact weed killers are any sprays designed to kill weeds quickly. There are some great tips for how to use Roundup and similar weed killers.
  • Spray Roundup when temperatures are between 60°and 85° Fahrenheit to ensure maximum effectiveness.
  • Apply Roundup early in the day so they are absorbed by the leaves during daytime photosynthesis.
  • Do not apply Roundup if rain is expected within the next 6 hours. Rain can wash away the active ingredients before they completely infiltrate the plants system.
  • Dont apply Roundup on an excessively windy day. Wind can cause Roundup to dry too quickly, which hinders it from entering the plants leaves.
  • Pre-Emergent Weed Killer: Apply in spring when soil temperatures reach 50° Fahrenheit for 35 days. This is when many seeds begin to sprout and is the effective window for pre-emergent weed killers.

Should I Mow Before Applying Weed And Feed

The question is, do you have to cut your grass before applying the weed & feed? If youve been following our blog for a while, you know that the answer is always it depends.

It depends on the type of weeds youre trying to get rid of, the species of grass you have, the phase of the season when youre applying herbicide, how the herbicide works, and, of course, how you mow.

If you have large broad leafed weeds, and are using a post-emergent product, then its best not to mow too short before putting down weed and feed, better to have a larger leaf area for the product to work on.

If you are going to be using a pre-emergent product, you can cut the grass not less than 2 days before application, then water it in, as it needs to get under the surface to start working.

So, the general rule is only mow at least 2 days before you apply weed & feed products, and dont mow before 2 days after the weed and feed application.
