DIY Rubbing Alcohol Weed Killer That Really Works

Correct application is crucial for success and to protect your garden and yourself.

1. Ideal Application Conditions

Apply on a calm, dry, sunny day. Wind will cause drift onto desirable plants. Rain will wash the solution away before it can work. Sunlight and heat help accelerate the dehydration process after application.

2. Application Technique

Spray generously, thoroughly wetting all leaves and stems of the target weed until the solution just begins to drip off. The goal is complete coverage. For best results, spray young, actively growing weeds. Avoid soaking the soil extensively, as this is wasteful and unnecessary since the alcohol does not target roots.

3. Post-Application Expectations

You will notice wilting and browning often within a few hours, with full desiccation occurring in 24-48 hours. Since alcohol is non-systemic, check the area in a week. If the weed regrows from the crown or roots, a second application will be necessary once new growth appears.

4. Precise Spot Treatment

For weeds growing very close to desirable plants, consider using a shielded sprayer or even a small paintbrush to dab the solution directly onto the weed's leaves, avoiding any contact with valued plants.
