Vinegar, a common household item, can effectively serve as a natural herbicide. This guide explores how vinegar functions as a weed killer.

How Does Vinegar Work as a Weed Killer?

Vinegar contains acetic acid, which is the primary ingredient that allows it to kill weeds. When applied to the leaves of plants, the acetic acid draws moisture out of the foliage, leading to plant desiccation and death. The higher the acidity (higher concentration), the more effective it is at killing weeds.

Benefits of Using Vinegar as a Weed Killer

• Non-toxic and safe for children and pets.
• Biodegradable and environmentally friendly.
• Inexpensive compared to commercial herbicides.
• Readily available in most households.

Limitations of Vinegar as a Weed Killer

• Effectiveness may be reduced during rainy or very humid conditions.
• Best suited for annual weeds rather than perennial plants.
• Can kill desirable plants if not applied carefully.

When to Apply Vinegar on Weeds?

The best time to apply vinegar is on a sunny day, preferably when temperatures are above 70°F (21°C). The warmth enhances the effectiveness of the acetic acid, making it easier for the solution to penetrate and dry out the weed leaves.

Application Method

1. Choose a vinegar with at least 10% acetic acid concentration for effective weed killing.
2. Fill a spray bottle with undiluted vinegar.
3. Aim the spray directly at the leaves of the weeds, avoiding any desirable plants.
4. Apply in the early morning or late afternoon to minimize evaporation.
