My nana swears by this DIY weed killer recipe. Here’s how it works

Dish soap acts as a surfactant in Nana’s weed killer recipe. Its primary role is to reduce the surface tension of the vinegar and salt solution, allowing it to spread more evenly across the leaves of the weeds.
This increased coverage ensures that the active ingredients can penetrate the plant’s defenses more effectively. The soap also helps the solution stick to the leaves, preventing it from being washed away by rain or irrigation.
6. Step-by-Step Guide to Making the Weed Killer
To make Nana’s DIY weed killer, start by gathering the necessary ingredients: 1 gallon of white vinegar, 1 cup of salt, and 1 tablespoon of liquid dish soap. Begin by pouring the vinegar into a large container or spray bottle.
Next, add the salt to the vinegar and stir until it is completely dissolved. This may take a few minutes, as salt can be slow to dissolve in vinegar. Once the salt is dissolved, add the dish soap and gently stir to combine.
Once mixed, the solution is ready to use. For best results, apply it on a sunny day when the weeds are dry, as this will enhance the solution’s effectiveness.
