The definition of weed depends on the perspective of the owner or the gardener. A mint plant in a cash crop field can be called a weed as its requirement is not there, whereas some people might want to purposely grow mint in their vegetable garden. Oh gosh, they are weeds!

Weed Killers

There are different ways to get rid of weeds growing in your garden or crop fields. Some of them are:

    1. Plucking – Pluck the weeds when they are small and before they could bear flowers.
    2. Mulching – mulch keeps sunlight away from underground seeds, so they do not sprout. 

It also retains moisture and enriches the soil.

 Pre-emergence herbicides prevent seeds from emerging from the soil. Preen (trifluralin) or Treflan and Dacthal are the two most commonly used pre-emergence herbicides in gardens.

 Non-selective herbicides like Glyphosate are used to clear all plants on land. 

 Please read the label for the list of vegetables and their plant stages before applying these weed killers.


Thus, we can say that a weed plant has two features: firstly, they grow up naturally and spread in no time to a large area of the yard if not treated or plucked properly, and secondly, they are unwanted in the surrounding by the owner or the gardener of the property. By using natural ways or chemicals, to can get rid of them.
