Buying Guide:

Are you a beginner at gardening and have no idea as to what to look for in a weed killer? Well, we have got you covered by giving you a brief buying guide on how to select it. To make sure your garden or plants look aesthetically pleasing, here are some factors you need to see to get the best results from weed killers.

Impact rate:

The first thing you need to see is how effective is it? Can it prevent the long-term growth of weeds? if yes then it has a high impact rate. Chemicals like Glyphosate and Imazapyr show the effectiveness of a weed killer.

Water-resistant:

People who can afford expensive weed killers should get a waterproof weed killer. A waterproof weed killer gets dried quickly and is strong. Inexpensive weed killers aren’t waterproof, so you can not apply them on wet plants.

Safety precautions:

Nozzles and backpacks ensure maximum safety while spraying weed killers. Stay safe while spraying the weed killer as they contain toxic chemicals.

Type of weed killer:

The common types of weed killer are given under. Select the one you need:

• Contact: These types of weed killers are ideal for yearly weeds prevention. They attack plants and kill them by weakening the weed but they don’t go to roots.
• Systemic: They are put on leafy parts of the plant, called foliage. The results given by these take time as they attack the roots of plants. Weeds that are difficult to kill can be killed by systemic weed killers.
• Residual: They kill all plants wherever they are applied. We do not recommend using these on crops as they also kill useful plants.
• Selective: Selective weed killers just kill the harmful weed without attacking the edible plants.
• Non-selective: Non-selective kill all plants in their closeness.
• Pre-emergent: People who know the common place where the weeds initially start to grow can prevent the growth of weeds by getting pre-emergent weed killers. These stop the growth of weeds even before their growth.
• Post-emergent: This is for visible weeds, if you see weeds and want them gone immediately use this type.

Weed growth preventer or a weed killer:

You should keep in mind whether you want to permanently get rid of a plant or you want it to grow again. For permanent elimination of a weed, weed killers work best. Likewise, if you want to prevent the growth of weed for a time being then weed preventers work best.

Area of weeds and size of weed killer:

Another most important factor is looking into the area that weed killers cover. We recommend getting a large area weed killer as it can be used in the future as well. People who just want to get rid of selective little weeds instead of whole lawns can opt for a small size one.

Organic or Inorganic:

Both organic and inorganic weed killers get the job done. It’s up to whether you want an organic weed killer or an inorganic one. Organic weed killers are natural and non-toxic to the environment and you. Inorganic, on the other hand, are more powerful but you need to be cautious because they can damage your skin and health.

Budget:

Consider the cost of weed killers too. Make sure, if you are getting an expensive one, that it comes with features that back up the price. Some weed killers have nozzle spray and tank sprayer with them so they will cost extra.
