If you're looking for a chemical-free, eco-friendly, non-toxic, and highly affordable method for improving the health of your garden, vinegar shines through.

Vinegar is an effective natural fungicide that can fight off plant diseases like downy mildew. You can apply a mix of warm water and apple cider vinegar on most plants.

However, avoid using it on succulents and plants with delicate leaves sensitive to acidity. Spraying it directly on the plant may also harm beneficial garden bugs.

Meanwhile, spraying straight or diluted vinegar along the edges of your garden, fence posts, and even yard decor can keep unwanted garden visitors, like cats and deer, away.

Vinegar is also an ant repellent and killer. When applied on ants or areas infested with ants, its smell will clear away the scent trail ants use to communicate.

This acidic liquid can also keep your gardening tools rust-free. Let your rusty tools soak in the bath of undiluted vinegar for 12 to 24 hours, then gently wipe away the corrosion.

Vinegar is also a potent herbicide but can damage plants with its acetic acid content. A concentration above 20% is better at weed control but can burn your plants.
