A Buying Guide To Weed Killers

The wrong weed killer can cost you time, money and valuable plants. It can be hard to choose the right product but our quick guide will hopefully make the experience less troublesome!

What You Need To Know

Types of Weeds

The first factor that you need to put in mind when buying a weed killer is the type of weeds that you want to eliminate. Once you have identified the weed, it will be easier to choose a weed killer that will get rid of them quickly and effectively.


The second thing to consider is how often the weed reappears after treatment. This will help you determine how strong you want your weed killer to be. A stronger weed killer containing triclopyr will also be needed to get rid of tough weeds like white clover and brambles.

Selective or Non-Selective

Two types of weed killers are available on the market today. There are the selective type and the non-selective weed killer. The former is ideal for use in areas where you have flowers and vegetables growing because this weed killer will only work to eliminate the weed and leave out the valued crops.

However, the non-selective will destroy the entire green plantation when applied. This type is the best lawn weedkiller to keep it looking good, free from weed. Choose whether you want to clear everything or you want to selectively remove the weed.


Q: What are some of the homemade remedies for weed?

A: Vinegar is a popular homemade herbicide to use as it is a non-selective weed killer and works on the max to clear small weeds. Salt is also another homemade weed killer that can be used to eliminate the weed as well as combat pests on your garden plants. Apply the sodium chloride powder on the soil and use a brush to keep it in place. These products are the cheapest way to get rid of weeds.

Q: Can one use trisodium phosphate as a weed killer?

A: No. Trisodium phosphate is a very strong and dangerous chemical that is poisonous when you come into contact with it. Be it when you touch or inhale, it is harmful to crops and pets. Therefore, it is not recommended.

Q: What can one use to de-weed the garden in rainy seasons?

A: Since most weed killers are prone to get washed off by rain once applied, there is the use of a propane weed burner torch to kill the weed. This is a de-weeding process that doesn’t involve the use of chemicals and it is ideal for use in any season, especially in the rainy season. You will remove weed like a pro using these weed killers.
