This simple, homemade weed killer might become your new go-to
Ingredients
Let’s talk ingredients, because this recipe is refreshingly straightforward. You’ll need:
- 3 cups distilled white vinegar
- ¾ cup regular table salt
- 2 teaspoons blue Dawn dish soap (it really does work best, though others can substitute)
- 3 teaspoons of liquid arthritis rub—yes, seriously! The arthritis rub usually contains capsicum, which helps break down the weed’s structure and speeds things along. You can find it easily in the grocery store or pharmacy for just a few dollars.
How It Comes Together
- To make it, grab a spray bottle and a funnel. Add the salt first, followed by the dish soap, vinegar, and the arthritis rub.
- Give it a good shake until everything is well mixed.
- When you’re ready to use it, spray the mixture directly onto the leaves of the weeds. You’ll often see results almost immediately, and within 24 hours the weeds are usually well on their way to withering away for good. It continues working as the plant dries out, which is oddly satisfying to watch.
Tips About Capsicum
- Because this recipe includes capsicum, you’ll want to be mindful while mixing and spraying.
- Avoid touching your face or eyes during use, and wash your hands well afterward—capsaicin has a way of making itself known if it ends up where it shouldn’t.
- If you’re sensitive, gloves are a smart idea. It’s also important to use extra care if you have pets that roam outdoors.
- Apply the spray directly to weed leaves and allow it to dry completely before letting curious paws back into the area.
- Used thoughtfully, this mixture is effective and safe, but a little caution goes a long way in keeping both people and pets comfortable.
A Few Important Garden-Loving Notes Before You Go Spray-Happy
- This is not recommended for weeds growing in grass, as it can damage the lawn.
- Aim carefully and avoid letting the mixture touch the soil—this is a leaf treatment only.
- Be extra cautious around flower beds, especially if your yard slopes, since runoff could affect nearby plants.
- While this is a very diluted saline solution and doesn’t harm animals or leave lasting effects on soil when used correctly, thoughtful application is key.
Used with care, this recipe a simple, effective way to keep weeds in check and get back to enjoying your garden the way you intended.
