7. Herbicide Application – Chemical Control Method

Beginners may consider targeted herbicide for large infestations. Glyphosate-based herbicides are effective for perennial weeds. Apply following manufacturer instructions carefully.

Herbicides ensure quick plant death. Protective gear is recommended to avoid exposure. Spot spraying prevents harm to nearby plants.

Additionally, it works on roots to reduce regrowth. Ideal for lawn edges or large garden beds. Overall, herbicides are efficient, fast, and scalable.

Pros

• Fast action

• Effective

• Scalable

• Beginner-friendly

• Root control

• Easy

• Reliable

Cons
