Citrus essential oil (10-15 drops): Contains d-limonene, which can boost herbicidal activity and smells great.
Boiling water: For immediate scalding of weeds in pavement cracks (use alone or before applying the vinegar mix).
Step-by-Step Instructions: Mix, Apply, and Maintain
1. Prep Your Space (Safety First!)
Put on gloves and eye protection, especially if you’re using stronger vinegar. Cover nearby desirable plants with cardboard or a tarp—this solution is non-selective and will harm any plant it touches.
2. Mix the Solution
In a large bucket or sprayer, combine:
1 gallon white vinegar
1 cup table salt (skip if treating garden soil you plan to reuse)
