So, weeds are the kind of plants that you don’t want to see in your lawn or you don’t desire for your lawn. Weeds are not individual but the universal problem for every gardener and its invasion in your vegetable garden, flower bed, or lawn.

Why it needs to control weeds:

Weeds are the most noxious plant for lawn and it can cover a lawn very quickly, and damage your grass or plants very badly. It competes with lawn grass or plants for light, water and nutrients, finally it appears as a most dangerous case for lawn and makes your lawn plant weaken and kill after a certain period.

Before spraying:

It is one of the crucial parts for you to understand how weed killers work before you spray. Is the sprayer weed killer can kill the weeds perfectly without damaging your grass or other plants? A weed killer can block the protein formation or destroy the root formation and interfere in the growth of weeds. It is not as dangerous as pesticides but you must need to be careful when you apply them. You must be known with some basic information before spraying.

Safety procedure:

safe use of weed killer

You have to bear in mind that safety procedures are first for you as well as others. So, concentrate on this issue from the very first thing. Wear personal protection equipment like long sleeves, gloves, and goggles as well as using a respirator and protective headgear. You must read the label with care to know what is the distance you need to stay out of the treatment area. It is very important to keep your pets indoors and children away from the sprayed area before and after.

Selecting the correct weed killer:

It is one of the best wonders and difficult for you to select the best weed killers from huge ones. The different chemical industries continually offer a new product of weed killers and remove the older one because of the environmental regulations. So, be careful about your choice, here we always recommend you to use the new ones.

Double-duty weed killer products can be a very effective way for you to tackle multiple problems.

When it is used for a broadleaf it is safe for most of the lawn but it can not affect the crabgrass. So, you have to find the correct one which can kill the broadleaf weeds as well as car grass weeds. Maybe it is somewhat costly but you can get a double result with less labor.

Pre-emergence WeedKillers:

Pre-emergence herbicides or weed killers are mainly used to control annual weeds, especially for Summer weeds. It helps the lawn to disrupt the life cycle of weeds in an established lawn. These herbicides are used to prevent the germination of weed seeds. To get a satisfactory result lawn owners should apply the herbicides before the weeds seeds become germinate, usually at the time of early Spring. It can be applied at any time of day and these create a chemical barrier in the soil to prevent weeds from emerging. A lawn owner needs to apply twice to control the invasive weeds like Crabgrass at an interval of eight weeks after the first application.

Eg: Dithiopyr and Benefin.

Post-emergence WeedKillers:

Post-emergence herbicides or weed killers are mainly used to kill the weeds upon contact which are absorbed by the plant tissue. It can be systemic or non-systemic. Systemic works effectively as moving through the plants to their roots when the plant is in an active growing period. Non-systemic damages the plant tissues and can be applied at any time of day.

It will be very effective for gardeners applying postemergence on the new and young weeds. It is used widely because of the maximum gardener face of lawn weed problems after the establishment of the weed population such as woody shrubs. To get a promising result the lawn owner needs to cut the weed down to the surface level and apply the herbicides when the new leaves and shoots appear becoming a few inches height as we mention it works best on new and young weeds.

Eg: Glyphosate.

Best time to apply liquid weed killer

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

Usually, a weed killer works best when the weather is dry but before it is too hot for several days because when it is monsoon season and the rainwater even a light shower can wash out the herbicides from the upper surface that you 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, especially 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 wider space of spraying of chemicals onto the other areas of land which can kill the desirable plants severely.

  • In Summer, early morning and late afternoon are best for applying weed killers. But it will be more convenient and effective for your lawn to apply it at the end of the season because the spray may evaporate in the heat of the full sun which prevails in the early summer. Must avoid applying it in the early afternoon in Summer because it can slow down plant growth and dry out the leaves quicker that reduces the amount of absorption of weed killers.
  • Fall is the great season to apply because the weeds are the most vulnerable in this season. By spraying post-emergence herbicides the weeds will survive in the winter. You need to apply to treatment at two-week intervals.
  • In winter, mid of the day when the temperature is high it is best to apply systemic herbicides because it works best during warmer conditions.
  • In Spring, It remains warm and it is the best season to apply weed killers and it has a great chance to apply in early spring because pre-emergence herbicides prevent the weeds from germination. You have to apply two treatments at eight-week intervals.

What time it needs to work:

This is the most important question, “What time a weed killer needs to work?”. It largely depends on the type of herbicides. Some weed killers kill weeds within a few days on the other hand some are needed a week or more. Also, it depends on the place where you need and why you need to treat. Due to the temperature concerns you need to apply weed killers early enough. You have to be concerned about the residual effect of weed killers, some have a high residual effect and remain toxic to plants for months. You must carefully read the label to ensure how long it takes to work and how long will it remain on your lawn.

Application strategy:

  1. Apply the liquid weed killers by using a sprayer.
  2. Apply it on dry grass because wet grass will dilute your weed killers.
  3. Apply It in wide and sweeping motions in calm weather.
  4. Must avoid one or two sweeping to a sole area.
  5. Avoid frost and freezing conditions.
  6. Apply lightly in low spots such as corners where runoff can accumulate to avoid damage containing plants and soil.
  7. Don’t apply it only to the soil.
  8. Though it absorbs through the leaves of weeds so you have to ensure that the spray must be in contact with the weeds for at least one or two days.
  9. Avoid when it is strong sunshine.
  10. Avoid mowing before application because it reduces the number of leaves that would absorb the herbicides.

 

Post-application strategy:

  1. Avoid mowing your lawn at least one week before the application because leaves absorb the weeds and it needs enough time.
  2. Hand-pull the weeds which can survive the weed killers with their roots.
  3. Don’t force yourself to apply over these plants, it is full of waste and failure of effort.
  4. After the removal of weeds, you can mow your lawn grass and notice that any kind of seeds can not spread. 
  5. Ensure favorable conditions such as adequate sun, interrupted water supply, and proper mowing to ensure that the weed seeds can not grow up again.

How often can we use weed killers?

It largely depends on what type of weed killers you are going to use. So before purchasing a weed killer read the label carefully to ensure about it. But many of the weed killers are designed for a maximum of two treatments per annum with different active ingredients. Two treatments in 7-8 weeks apart from one another will create the optimal result. One is in early spring than the other 7-8 weeks later. Also, you can do your last application in the fall, October is best because weeds can’t survive in winter 

Final thought:

From the above consideration, it is assumed that the best time for spraying liquid weed killers is in Spring and fall because we can not spray it in very hot weather as well as very cold weather. And in spring and fall, there remains a moderate temperature which is very effective to execute the works of weed killers.

Spray the weed killer in early spring and let another application for 2 months later. You can also apply it in fall because the weeds don’t survive in winter, and in this case, October is perfect to spray. If you are a beginner I believe now you can apply your liquid fertilizer in a very effective way in the proper time with proper weed killer in a proper way.
