#### 4. **Pest Control Without Chemicals**
Hydrogen peroxide can deter soft-bodied insects like aphids and fungus gnats by disrupting their life cycle. It’s a safer alternative to harsh chemical pesticides.
**How to Use:**
Spray a diluted solution (1 part hydrogen peroxide to 4 parts water) directly onto plant leaves, stems, and surrounding soil.
#### 5. **Soil Aeration Boost**
When used correctly, hydrogen peroxide adds extra oxygen to the soil, helping roots grow stronger and healthier — especially in compacted or poorly draining soil.
**How to Use:**
Water with a solution of 1 teaspoon of hydrogen peroxide per cup of water once every few weeks.
### A Word of Caution
While hydrogen peroxide is natural and biodegradable, it’s still a strong oxidizer. Always use a 3% solution (the kind found at pharmacies), dilute it properly, and avoid overuse, as too much can harm beneficial microbes in the soil.
### Final Thoughts
Hydrogen peroxide is one of the most underappreciated tools in a gardener’s arsenal. It’s cheap, easy to use, and multitasks like a pro — from saving sick plants to helping your garden thrive. Next time your garden needs a little TLC, consider reaching for that trusty brown bottle.
