What are Weed Killers?

Weed killers are chemical-based herbicides that target different weeds in the best way without hurting other plants or grass. If you manage to find the right weed killer for specific weeds, then your job becomes easy.

These come in a lot of different varieties. Some are entirely herbal, while some contain toxic chemicals. You must take into account the size and location of the area and the type of weed that you want to get rid of.

When to use Weed Killers?

You can remove weeds in the following ways:

  • By Hand: hold the weed close to the ground and pull it out with the roots. You can do this only if there are a few weeds, but it is not possible with widespread growth. It will also not work if the weeds are too deep-rooted.
  • Fork out: dig and fork out the weeds with care to remove every small root without damage to the plants you want to keep. Weeds are stubborn, and any small part of the root may sprout into a new plant.
  • Hoeing: Using a hoe blade to cut off the weeds is a good option, but this is not effective in wet weather. Hoeing may also bring the seeds of the weeds back to the surface.
  • Mulching: by applying a thick layer of mulch to the soil can help in suppressing the weeds.

All these methods are limited in their functions and require a lot of time and effort on a user’s part. This is why weed killers are such a great option.

They are easy to use and very effective. Some selective weed killers act on specific weeds, and the results are excellent. For different types of soils and locations, you must use different types of weed killers.

Types of Weed Killers

  • Pre-emergence: perennial weeds store energy in their roots in the fall season before they go dormant. Spraying these herbicides in early fall will prevent the weeds from storing energy. There are fewer chances of weeds re-emerging after winters.
  • Post-emergence: these herbicides are used for weeds that have already germinated. Spraying this weed killer is most effective when the weeds are in the early stages and are yet to produce seeds.
  • Selective: as the name suggests, they only kill specific weeds. They are suitable for large lawns and do not cause any damage to the grass. However, you must check before buying that there is no harm to the grass.
  • Non-selective: they are also called wide spectrum herbicides and can kill almost any plant they contact. They are perfect for areas like pathways, sidewalks, driveways, etc.
  • Contact: it starts to work as soon as the plants come in contact with this herbicide. These are perfect for killing annual weeds and are fast-acting.
  • Systematic: this is a potent herbicide that can travel down to the roots even if applied on the leaves. They take time but are more methodical and kill the plants thoroughly.
  • Residual: they create a barrier in the ground, which prevents the seed from germinating. They remain in the soil for months and control weed growth for a long time.

How to Use Weed Killers?

It is quite simple to use weed killers, but you must follow all instructions and directions provided on the cover for each product. You can spray the herbicide with:

  • Water can: use an old watering can for applying weed killer in a controlled way. Remember to clean thoroughly or use a separate water can for watering other plants.
  • Pressure sprayer: for larger areas, these sprayers are better. They come in a variety of designs. You can choose from chest or back-mounted or pull it behind you on wheels.

Things to Consider When Buying Weed Killers

Before selecting any herbicide, you need to consider a few things for effective weed management.

  • Usually, you need to mix water with weed killers before spraying. Check the concentration level to understand how much do you need for your lawn or garden.
  • There are different types of weed killers, and you should choose carefully so that there is no harm to the grass and plants.
  • Some weed killers remain in the soil for months and can adversely affect plant growth and soil productivity.
  • Check the area where you will use the weed killer and its proximity to other plants, people, animals, etc.
  • How fast do you want the result? Some herbicides act very fast, while some take time to show results.
