Spot Treatment Is Better Than Broadcast Application

It’s no surprise that manufacturers of lawn care products, many of which publish a lot of online advice articles, insist that applying lots of chemicals over the entire lawn is the best way to control weeds. Their advice begins with broadcast application of pre-emergent herbicides in the fall or early spring, and continues with at least one, and preferably multiple, widespread applications of post-emergent herbicides at different intervals through the spring.

The advice becomes much different when you consult academic sources, such as the lawn-science departments at various universities. These scientific experts understand the dangers that over-application of herbicides, pesticides, and chemical fertilizers pose to water sources through run-off, and here the advice is always to treat weeds in the least toxic method possible, avoiding broad applications of chemicals whenever possible.

Instead, they argue it is best to avoid chemical means if possible, and if they are unavoidable, to spot-treat individual weeds with a spot-targeted spray rather than to spray or spread a dense layer of chemical over the entire lawn. Spot-treating weeds may sound like a lot of work, but a homeowner soon finds that it’s not a great burden to follow weekly lawn-mowing chores by walking the lawn with a hand sprayer and applying a small dab of weed killer to the weeds that are spotted. Over time, as most of the weeds are killed, it becomes relatively quick work.

How To Apply Various Types Of Weed Killers

The weed-killing pesticides are mainly known as Herbicides. With Herbicides help, you can get an almost weed-free lawn. You can increase the productivity of vegetables and fruits significantly. However, to get strong and healthy plants with a weeds-free yard, you must understand the products working procedure and follow some simple rules.

All weed killers are separated into two types:

  • ;;Non-selective herbicides;
  • ;;Selective herbicides;

There are many non-selective herbicides available in the market, such as Roundup, Hurricane Forte, etc. Typically, non-selective herbicides type weed killers are used before cultivating lawns or gardens.

Solid herbicides such as glyphosate that is mainly based on substances that can destroy all plants virtually. A wide range of selective action products is capable of killing. Dandelions or chamomile can be an example of it.;

During spraying, a glyphosate-based weed killer should have to be very conscious so that it doesnt fall on the leaves of plants; even a small drop of this type of pesticide can cause your fruit tree shrubs death.

It is good to spray soil herbicides when spreading the weed seeds into the soil because the application of these types of drugs directly to the ground affects the weed seeds adversely.

Both soil and systemic herbicides are excellent in their sector. We cannot compare them with each other. Because Systemic herbicides affect the plants, and Soil herbicides affect the seeds.

Controlling Lawn Weeds With A Pre

Pre-emergent weed killers control annual lawn weeds while they sprout, which means the herbicide must be on the lawn before the seeds begin to germinate. Annual plants grow during one season, and then set seed and die. Summer annual weeds like crabgrass and goosegrass germinate in the spring and winter. Annual weeds like common chickweed and henbit sprout in early fall. Consequently, to control summer annual weeds, apply a pre-emergent weed killer in early spring, and to control winter annual weeds, apply a pre-emergent herbicide in early fall. If you can already see annual weeds in your lawn, it’s too late to apply a pre-emergent herbicide.

When You Should Spray Your Weeds

The best time to treat weeds is when they are actively growing. This means you should start spraying and treating in the spring, usually sometime in April. Youll have to maintain your weed-killing regiment into late September/early October.

Its best not to jump the gun when using weed killers. Theres a lot of weeds in early spring that wont surface until later on in the year. Most weed killers are contact sprays: The treatment will only be effective if they make direct contact with the weeds. Youre better off waiting until May: By that time most of the weeds will have emerged, making them much easier to dispose of.

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.

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

If properly applied and watered into the soil, pre-emergent herbicide lasts 6-8 weeks. That means that for up to 2 months, any weeds that try to sprout in your lawn will be killed as they germinate.

To ensure maximum effectiveness of your pre-emergent, spread your weed killer at concentrations recommended by the manufacturer, using a sprayer or a drop spreader .

For longest-lasting results, after application, water the pre-emergent into your soil with 0.5 inches of water. Thats about half an hour of watering with a sprinkler. If you dont have a watering system, plan to spread your pre-emergent 2448 hours before rainfall and let nature do the watering. By watering pre-emergent into the soil, you ensure it forms a barrier beneath the surface to stop those sprouting seeds.

Does The Type Of Weed Impact How Effective Weed Killers Will Be

Yes, the effectiveness of weed killer will change depending on the type of weed you are trying to get rid of. This is mainly to do with its life cycle.;

You are likely aware that there are countless types of weeds. Read our ultimate guide to invasive weeds here if not. However, all these different types of weeds have different life cycles, and this affects the ideal time of year for targeting them.;

For example, some weeds grow in Fall and Winter, dying off in the same Spring and Summer, while some are the other way around. Some weeds are more resilient and will take a full two years to complete a life cycle before they die. And some will return year after year.

Therefore, when youre asking what is the best time of year to use weed killer, the answer will depend on the specific weed you are targeting. You will need to know the life cycle of the weed to ensure you target it at its most vulnerable.;

Classes Of Weeds: Broadleaf Grassy Sedge

First, know your target. Weeds fall into;three classes:;broadleaf, grassy and sedge.

Broadleaf weeds produce two seed leaves as the plant emerges and generally display wider leaves and branched stems. Broadleaf weeds include white clover, dandelion, thistle, pokeweed and even poison ivy.

Grassy weeds produce one seed leaf, like regular turfgrass. Examples include goosegrass, crabgrass and rushes.

Sedges also produce just one seed leaf, but in cross-section, the leaves show a triangular shape, as with yellow nutsedge.

What Time Is Best Time For Using Weed Killers

Spring is the best time for using weed killers. It would be better to use weed killer before a few weeks of cultivating the trees in your lawns. To destroy weeds entirely, you need a second treatment in between 2-3 weeks. In this case, the rest of the weeds deep into the soil will be destroyed completely.

At the time of weed control on your lawn, you must have to prevent the spread of seeds and destroy all young weeds before flowering. If you apply these tips, weed seeds will be decreased drastically.

In this case, it is a crying need to mow all of the overgrown weeds, then wait and give them to grow to 2.6 3.0 inches. Finally, apply weed killer on them.

Everyone should be conscious of some factors before applying a weed killer. Those are: ;

  • ; ;Dosing accuracy;
  • ; ;Processing of actively overgrown weeds;

Tips For When And How To Apply Weed Killer To Your Lawn

Preen Lawn Weed Control

When planning to apply weed killer plan around a predicted rainfall or sprinkler application, and severe hot days or mowing schedule.Weed killers are a contact killer, meaning they absorb the chemical through what comes in contact with the leaf surface and then translocates the chemical throughout the plant. Since weed killers are dependent on contact, it is very important to get good contact with the weed.

Granular weed killers should be applied when grass is damp and should not be watered for 48 hours after application. The dampness of the grass ensures the granular weed killer will “stick” to the leaf. Water applied too soon after application can wash off the weed killer from the surface of the weed before it can be absorbed.

To get good contact with the weed, don’t mow the grass before applying weed killers. Mowing eliminates the weed’s surface area and ultimately decreases the success of the weed killer. Plan to leave your grass uncut for two days after application and five days before.

During drought conditions or if you are having trouble getting adequate control, add spreader sticker which will increase absorption of the weed killer. During stress periods, plants tend to be more defensive and the addition of spreader sticker can be beneficial.

Applying weed killer is a five-step process:

  • Don’t mow the lawn before or after weed killer application
  • Plan around rainfall, or sprinkler application
  • Don’t water after treatment for two days
