How Soon After Rain Can I Spray Weeds

Essentially, you want to make sure you dont spray weeds when theyre wet whether thats from rainfall, irrigation or dew.

Waiting for the leaves to dry may take hours and sometimes it will take longer when the weather is cooler. Thats not always convenient, but it does mean you wont be wasting your time or your money applying an ineffective chemical.

Still, always make sure to spray after the leaves have dried, and if it does rain again unexpectedly after applying your herbicide, you may need to repeat the application.

Now that you know the type of weed you have, you face more choices.

Your particular weed may be best fought by either a liquid or granular herbicide.

Liquid herbicides are usually mixed with water and sprayed from a handheld pressure sprayer.

Granular herbicides are mixed with an inert carrier like clay or lime, or a fertilized carrier and spread from a fertilizer spreader.

Selective herbicides kill specific plants. If the label says broadleaf herbicide or something similar, it is selective. If you follow label directions, you can spray it and it will kill the weeds without killing your grass.

Nonselective herbicides kill whatever they touch. For these, you need a spray bottle and careful aim.

There are two types of spraying, broadcast and spot. Dont mix them up, or you could kill your lawn.

Broadcast is applying the herbicide across the entire lawn, You broadcast spray selective weed killer, since the lawn can tolerate it.

Spot application uses an applicator, like a pressurized sprayer, to apply the herbicide directly to the weed in the effort to affect no other plants.

Selecting The Correct Weed Killer

Wondering what happened to the good old stuff that used to work for your Dad?

The chemical industry is continually introducing new garden products. They regularly remove old products, often due to environmental regulations, sometimes because it is not profitable for them to incur the cost of maintaining registration on a label.

Trust the new ones, if you have been attentive with your choice.It pays to look around at the options when you are in a garden department with an extensive selection.

Double-Duty weed killer products can be an effective way to tackle multiple problems. For example, a basic herbicide is a broadleaf weed killer safe to use on most lawns, but it would not affect crabgrass. It is now possible to get the same broadleaf killer with a crabgrass killer added.This may cost more than the original single formula, but not as much as getting two separate products, and you have less labor.

Be cautious, however, about trying Neighbor Ned’s boast about mixing his own garden cocktails. Chemicals that are combined can increase phytotoxicity .

A mixture might be harmful to a plant even if both chemicals alone would not be. This is another reason why you should not increase the dosage of chemical in your spray mix.

Safety Rules For Using Weed Killers

If you are thinking about safety, a question is coming into your mind. Can weed killers harm humans? Yes, it is less harmful to humans, but sometimes it can be deadly. All substances of herbicides have various degrees of toxicity. You will find the level of danger and toxicity in its label.

Most of the herbicides are medium-toxic for the human body. But they can be very harmful to pets and little kids, especially liquid herbicides. When applying herbicides, they must have to wear protective clothes, respirators, goggles, and rubber gloves.

Important advice: Before applying weed killer, you must have to protect exposed skin and mucous membranes from any contact with weed killers.

The contact of weed killer with your skin can be caused by rash and redness. Wash your skin properly with water if a single drop of herbicides falls on your skin.

If the herbicide affects your mucous membranes, wash the digestive tract with plenty of fresh water and then consult with a doctor.

After using weed killer, wash the sprayer with the detergent solution until the substances are eradicated.

Things to consider at the time of reading the label

Before applying weed killer, read the instructions of the label of weed-killer properly. It would be best if you remembered that most of the herbicides come from vegetative weeds. Check the label and apply the pesticide according to the instruction provided on the label. You will also get information about the time of action and properties there.

What Is The Best Time Of Day To Spray Weeds

How to Use Ortho® WeedClear Lawn Weed Killer Ready-To-Spray

The most critical factor on when is the best time to spray weeds is the weather, so this will vary from season to season. Most herbicides work best when application occurs during several days of dry weather, but not extended dry periods. It should not be too hot or dry, because the heat stress will reduce the weeds capacity to absorb the herbicide.

This is also the same with winds if its too breezy, the spray will drift off from the target plants and affect the rest of your garden.

And one final tip:

If you live close to a next-door neighbour, you should also consider communicating with them and discussing your plans to spray weeds. This is so that you can avoid inconvenience to them and their property. The same should happen in your own household, informing everyone about it so pets, children, or other potted plants arent in the area during or after spraying herbicides.

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.

Using An All Natural Weed Killer Is Possible

There are many environmentally safe ways to remove weeds. Many of these are homemade methods.

You can use vinegar, which can handle weeds on:

  • Lawns
  • Sidewalks
  • Driveways

Vinegar with the highest acidity is acceptable even in organic farms. It has the highest effectiveness in spring, when the weeds are small and havent yet entered the flowering phase. But even though its a non-chemical weed killer, vinegar destroys not only weeds but also crops. Its better not to use it in a garden full of growing vegetables.

You can also use salt or bleach, but these agents are so strong that when they penetrate deep into the ground, nothing can grow for a long time. Its not the best weed killer for grass.

Facts About Weed Killers & Chemicals

Weed Spraying in minneapolis Lawn

Satisfaction with any product comes when you have reasonable expectations about the results.

It may seem like the best product SHOULD kill everything you want it to kill, in one application, with no negative results, and very little bother.

That is not realistic. Here is what you need to know:


Lawn weeds may die after one application of weed killer. Additional spraying may be required for more mature weeds, for perennial weeds with stronger root systems, or for some stubborn types, especially those with waxy or hairy covering.

Definitions: Mature Weeds = the massive ones in your lawn because you waited too long Perennial Weeds = hardy weeds, like dandelions, that keep returning. By their nature, they survive season to season, unless you knock them out.

Stubborn Weeds = do not readily absorb herbicides, or drink it down and laugh in the face of danger probably genetically modified by mad scientists, hence the ugliness of waxy or hairy coverings


Weed killer does NOT work better with a stronger concentration. It is better to spray again, rather than go with a heavier dose which can have negative consequences.

Additional reasons to avoid this will follow below, but this is the #1 error that gardeners make when they get the notion to kill those darn weeds.


Weed killers take time, more or less. Some work quickly, within hours you may see dieback. Others work slowly and may take many days before you notice any result.

When To Fertilize Your Lawn

Fertilize your lawn as soon as the growing season begins. Grass doesnt start growing very well until the soil is moist and seeds are ready to take root. Also, if your lawn gets plenty of sun, it will grow quickly and may begin to green up before the weather gets too cold.

However, fertilizing too early will cause your grass to grow too quickly, and it may be at risk of overcompensation, which is when the grass starts growing too quickly and then freezes or gets too dry. The opposite also applies, such as a lawn that has too much water.

Its also a good idea to fertilize your lawn in the fall or during the winter to help keep your lawn green. If you wait until the spring, you may have to amend the soil to prevent weeds from growing back. It can take quite often.

Clean Up The Lawn & Bed Areas

As I said, Spring and Fall Weed Spray treatments generally require a yard clean up of dead leaves, limbs, trash, and other debris. This is an important step especially for pre-emergent applications but also to expose weeds to the broadleaf herbicide. The more pre-emergent we can get to the lawn surface and the most weed killer we can get on the leaf surface, the better.

Rule 2. Make sure you are using a spreader sticker.

A spreader sticker is a liquid additive that you mix with the weed killer and water. It helps the herbicide stick to the leaves more effectively, thus having better results.

Rule 4. Avoid overlapping so that you dont burn the grass.

If you overlap too often when spraying for weeds, you risk damaging the lawn and potentially killing your desirable grass. You might consider using a marker dye to see where you have already sprayed. Certain retail
