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.

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.
