Pre-emergence Weed Killers

Pre-emergence weed killers are applied in early spring or late winter to kill weed seeds before they can grow. They are often used to control annual weeds such as crabgrass, chickweed, henbit, goosegrass, and broadleaf weeds. It’s important to point out that pre-emergence weed killers are not effective on weed seeds that have germinated already. These herbicides are useful for controlling weed seeds for 6 to 12 weeks. They shouldn’t be used on lawns within 2 to 4 months before seeding and at least 1 month after seeding because they can also kill grass seeds.

Post-emergence Weed Killers

Post-emergence weed killers are used to kill weeds that have already begun to grow. These herbicides are effective while the weed plants are still young and before they have begun to produce seeds.

Non-selective Weed Killers

Non-selective weed killers, also known as broad-spectrum herbicides, kill almost all plants they come into contact with, including turf grass. They include glyphosate, glufosinate, and diquat. Non-selective weed killers are commonly used to kill weeds in driveways and sidewalks.

Selective Weed Killers

Selective herbicides are the most common type of weed killers. They only kill certain species of plants. Most selective weed killers target broadleaf weeds. You can apply them to large lawns without hurting the grass. However, some selective weed killers that target sedges and rushes can be harmful to some types of lawn grass.

Selective herbicides include granular weed killer for lawns. To achieve an even spread, apply granules with a rotary or drop spreader. Mix weed killer powder with water based on the dilution rate suggested on the label, then spray the solution evenly to your lawn. Meanwhile, apply a liquid weed killer with an air sprayer to achieve even coverage.

Contact Weed Killers

Contact herbicides kill only parts of plants that they come into contact with (usually the above ground leafy parts). These weed killers don’t kill underground roots or rhizomes. They usually require several applications to get rid of weeds completely. In lawns, they are usually used for spot treatment of weeds growing in small or isolated areas.

Systemic Weed Killers

When applied to above ground leafy parts of weeds, systemic weed killers travel into the weed’s vascular system and roots. Systemic herbicides break down the weed’s ability to transport water and nutrients throughout the weed plant, killing it slowly as a result. Some examples of such herbicides include dichlorophenoxyacetic acid, imazaquin, sethoxydim, and dicamba.

Natural Weed Killer for Lawns

The following natural weed killers can work, but they have limitations.

Corn Gluten Meal: This pre-emergent organic weed killer for lawns can be used as a weed control product. A by-product of corn milling, corn gluten meal works by inhibiting weed seeds from growing. To be effective, it must be applied in spring before weeds begin to sprout. However, it may take several applications before you can see results. Corn gluten meal is a non-toxic weed killer for lawns (prevents weed seeds from germinating to be exact).

Vinegar: Acetic acid is the active ingredient for this natural weed killer for lawns. The vinegar you buy from the supermarket contains about 5% acetic acid. Vinegar burns the tops of weeds but isn’t effective for weeds with well-established roots. If you’re not careful, it can also kill nearby plants. To be effective, frequent application is also necessary.

When to Apply Weed Killer

Controlling weeds is an important aspect of lawn care. If you’re struggling with weed invasion in your lawn, you are not alone. While manual methods such as tilling can help control weeds, some gardeners and homeowners prefer to use herbicides for faster lawn weed control. If you go the chemical route and use the best weed killer spray for lawns at the right time, it can help you achieve a weed-free lawn. Much of it depends on the type of weed killer you’re going to use.

Most weed killers work best when they are applied during several days of dry weather. This is because rainwater can rinse off the herbicide from surfaces you need to treat. Also, any residual effects of the weed killer will get diluted by rain, which can lead to inefficacy. Another weather factor to consider is wind, specifically when applying nonselective herbicides that kill all plants, including desirable vegetation, flowers, or vegetables. Windy conditions can create drift, blowing the chemicals onto other areas of the garden and killing desirable plants.


There are a number of best weed killer for lawns that any lawn owner can choose to go with today. Like we have seen they are really affordable and quite budget friendly. Weed control options come in the variety of types. Some of the most common types include the following options.


The crabgrass recommended preventers are rich in nitrogen. Because of this, they work both as lawn inhibitors and also as a weed killer. They will inhibit the germination of crabgrass and many other lawn weeds.


Lawn feed such as fertilizers and their ideal application schedule will boost nutrients on your lawn. At the same time, they will also tackle weeds. They will prevent against any form of lawn weed invasion and could work all the yearlong, especially when done properly.


Finally targeted weed control is also a great option if you are looking for the best weed killer for lawns and don’t have enough budget for over the counter options. It can be a targeted post emergence herbicide or weed control procedure.  It works well on weed seedlings that are just emerging.


If you are using the best weed killer for lawns especially over the counter options, there are a number of safety precautions that you should choose to go with. Here are some tips for using weed killer on a lawn:

  • You must use the right application tools.
  • Wear gloves around your hands
  • Have an overall or a dust coat
  • Protect your eyes, mouth, and nose
  • Follow the manufacturer’s instructions to the top.
  • Ask for expert help if you don’t know what to do.

  • Keep far away from the reach of children


Like we have seen, there are a number of best weed killer for lawns. They include liquid weed killers, granular weed killers, weed killer sprays, over the counter options, and fertilizer application routines. The choice is yours.

Personally, I would suggest going with both the fertilizer application schedule, the best over the counter weed killer for lawns, and above all a targeted weed control procedure. This should be quite effective.
