After 20 something years of using food grade Hydrogen Peroxide, we are still constantly amazed over its many uses…
Where to buy food grade H2O2
Garden of Eden
Store food grade H2O2 in a labeled UV protected bottle and place in a cool, dark, and safe place away from pets and children. H2O2 reduces in strength less than 1/2 of 1% per month when stored in a refrigerator (but not in a freezer!).
To make a 3% Solution, mix 1 oz. of 35% food grade Hydrogen Peroxide with 11 oz. of Distilled Water.
Some of the many uses of food grade Hydrogen Peroxide
Garden
- Sprouting Seeds: Add 1 ounce of 3% Hydrogen Peroxide into 1 pint of water and soak the seeds overnight. Add the SAME amount of Hydrogen Peroxide when you rinse the seeds. (Some people have reported 3/4 inch Sprouts in 24 hours!)
- Plants & Flowers: Add 1 oz. of 3% Hydrogen Peroxide in 1 quart of water to water or mist plants. (This will enhance the growing environment)
- Insecticide Spray: Add 8 ounces white sugar and 4 - 8 ounces 3% Hydrogen Peroxide to 1 gallon of water.
Food and Water Storage
- Salad: Add 1 Tbsp. of 3% Hydrogen Peroxide to 1/2 cup of water and spray the top of the salad before covering and refrigerating.
- Vegetable Soak: Add 1/4 cup of 3% Hydrogen Peroxide into a gallon of cold water. Soak light/thin vegetables (Lettuce, etc.) for 20 minutes. For thicker skinned vegetables (like Cucumbers) for 30 minutes. Drain and dry (they’ll keep longer). If time is an issue, you can spray vegetables with straight 3% Hydrogen Peroxide, let stand for a couple of minutes, rinse and dry.
- Milk: Add 2 drops of 35% Hydrogen Peroxide (full strength) per gallon of milk. This extends the expiration date considerably (works great for us!).
- Water Storage (For two months or more): Add 30-50 drops of 35% Hydrogen Peroxide in 1 gallon of water.
Cleaning House
- Sparkly Clean Glassware: Add 2 oz. of 3% Hydrogen Peroxide to your regular dishwasher washing formula.
- Kitchen: Keep a Spray Bottle of 3% Hydrogen Peroxide in the kitchen. Use it to wipe clean counter tops, inside your refrigerator and appliances.
- Washing/Laundry: Add 8 oz. of 3% Hydrogen Peroxide to your wash instead of Bleach .
Health and Hygiene
- Bath: Add 1/2 to 1 pint of 35% Hydrogen Peroxide to a full bathtub. ( Try not to use this close to your bedtime as the increased oxygen absorption may keep you awake.)
- Mouth and Teeth: Add enough 3% Hydrogen Peroxide to baking soda to make a toothpaste. Use 3% Hydrogen Peroxide as a mouthwash.
- Humidifiers/Steamers: Use 1 pint of 3% Hydrogen Peroxide to 1 gallon of water.

I know it's been quite some time since I last posted and I apologize. Frankly, there hasn't been much going on in the garden over the past month or so and I'm really just now getting over early January's post-holiday hump. It's been cold here the past few days - in the low teens during the early morning and not warming much past the mid-twenties by afternoon. Wisconsin-ites may scoff at such toasty winter temps, but here in Pennsylvania such cold days have been few and far between the past few years. Global warming strikes again.
As I sit at my computer and look out the window, I can see a nice little treasure that I discovered just a week or two ago. Clinging to the branch of one of the Lawson's cypress we planted this past spring is a praying mantis egg case. I was so pleased to find it since I did not see a single adult mantis in the garden the entire summer. I can't wait to see all the babies this spring. What amazing creatures they are. Here is some information about praying mantids from my forthcoming book. As I said in an earlier post, I learned a lot while researching the book and here are some interesting little tidbits:
- There are over 20 native species of mantids found throughout the U.S. with many others introduced.
- An adult praying mantis can grow to 5 inches in length and live an average of 10-12 months.
- Their egg cases appear as spongy brown masses clinging to branches and twigs.
- It's true. Sometimes the female does consume the male after copulation.
- Large mantids can eat small salamanders, frogs and birds, though their diet consists mainly of other insects.
- To encourage praying mantids to make a home in your garden, focus on planting specimens suitable for egg laying (since mantids do not consume pollen or nectar). Good choices include golden rod, iron weed, ornamental grasses, Joe Pye weed, raspberries and other brambles.
- If you choose to purchase mantids for your garden and you live in a northern zone, be aware that Chinese mantids are more voracious than our native varieties, but they aren't nearly as winter hardy.
- Praying mantids are not discriminating eaters. They will catch and consume beneficial insects as quickly as pest insects, but they can definitely be added to the list of critters having an overall positive impact on your garden.
- Their heads can swivel 180 degrees and their compound eyes are perfect for spotting passing prey as they lie-in-wait for the ambush!
