The Complete DIY Recipe and Mixing Instructions

This recipe balances potency with accessibility, using ingredients easily found at home or in local stores. For best results, use the highest acetic acid concentration vinegar you can safely handle.

1. Ingredients You Will Need

Gather the following items before you begin: one gallon of white vinegar (at least 5%, but 10-20% horticultural vinegar is far more effective for perennial weeds), two cups of Epsom salt, and one-quarter cup of liquid dish soap (preferably a simple, non-ultra, biodegradable brand like Castile soap). You will also need a large one-gallon spray bottle or a garden sprayer, a long spoon or stick for stirring, and protective gear.

2. Step-by-Step Mixing Process

First, pour the gallon of vinegar into your mixing container. Slowly add the two cups of Epsom salt to the vinegar. Stir vigorously and continuously for several minutes. The salt will eventually dissolve, but it requires patience and thorough stirring. Once the salt is fully dissolved, carefully add the quarter cup of liquid dish soap. Stir gently to incorporate; avoid creating excessive suds. The soap is the final ingredient to prevent premature foaming. Your natural weed killer is now ready for immediate use. Any unused mixture should be stored in a clearly labeled container, out of reach of children and pets.
