Planting After Vinegar-Salt Weed Spray: Wait 48 Hours

Homemade vinegar-salt weed killer (acetic acid + sodium chloride) is a contact burndown. The soil impact is temporary—here's the timeline.

Replanting Window

• Wait 48 hours after application before planting.
• Acetic acid breaks down rapidly in soil moisture (hours to days).
• Salt disperses with watering/rain; minor unless applied repeatedly in same spot.

Best Practices

• Don't spray before rain—dilution kills efficacy.
• Spot-treat only; avoid broadcast application.
• For root crops: ensure salt hasn't accumulated (test if unsure).

Why This Mix Works

• Vinegar (acetic acid) desiccates foliage.
• Salt enhances desiccation and lingers slightly longer.
• Dish soap (often added) improves leaf adhesion.

Safe for replanting in 2 days. Just don't make it a habit in planting beds—mechanical removal + mulch is better long-term.
