My Nana Swears by This DIY Weed Killer Recipe — Here’s How It Works
In the world of gardening, weeds are the ever-present nemesis every gardener faces. While store-bought weed killers can be effective, they often come with a cost: harsh chemicals that may harm the environment, pets, and even the plants you’re trying to protect. That’s why many gardeners are turning back to natural solutions.
One such solution comes straight from the wisdom of my nana—a seasoned gardener with decades of experience. Her homemade weed killer is simple, effective, and eco-friendly. Best of all, it uses common household ingredients you probably already have on hand.
1. The Origins of Nana’s DIY Weed Killer
Nana’s recipe has been passed down through generations, a testament to its reliability. Back in the day, commercial herbicides were expensive or unavailable, so gardeners relied on natural remedies to protect their crops and flowers. Over time, this vinegar-based blend became a go-to solution in her garden.
Her tried-and-true formula:
1 gallon white vinegar (5% acetic acid)
1 cup salt
1 tablespoon liquid dish soap
This simple mixture has kept her garden weed-free for years without the risks associated with synthetic chemicals.
2. Why It Works: The Science Behind the Ingredients
Each ingredient in Nana’s recipe plays a key role:
Vinegar – The acetic acid burns and damages the weed’s leaves, stopping growth.
Salt – Dehydrates the plant and prevents it from absorbing water, making it more difficult for weeds to recover.
Dish Soap – Acts as a surfactant, helping the solution stick to the weed leaves so the vinegar and salt can do their job.
Together, they form a natural, powerful blend that targets weeds on contact.
