Although article on H peroxide for plants abound , it actually has few proven gardening - colligate habit . As Jeff Gillman , Ph.D. , author ofThe Truth About Garden Remediesand director of theUNC Charlotte Botanical Gardensnotes , “ In my limited tests and experience , it is perfectly useless for controlling disease . ”
Gillman says that atomic number 1 peroxide “ is a airfoil sterilant , and for that purpose , it works well . But it bring out down apace when it is put on , so it is n’t going to provide lasting disease control . It ’s just H2O with an spare atomic number 8 atom , so it ’s useless as a fertiliser and it is n’t something that could supply reliable insect mastery . ”
Benefits of Using HydrogenPeroxide for Plants
Because this special chemical chemical compound kills good germ as well as bad , you ’ll probably want to avoid applying it to soil in most cases . So , as far assecret ingredient for gardeninggo , hydrogen peroxide for plant may seem pretty much a bust ! But thehousehold stapledoes have a few America for home gardeners .
It sanitizes the surfaces of tools and produce.
As Gillman notes , peroxide is a open sterilant . The same timber that equip it to clean cuts and scrapes also enable it to clean bacterium and fungus kingdom from theblades of garden peter , as well as planting trays . It can even pick the outside surfaces of produce . Keep in head , though , that a University of California study find that peroxide did not kill fire blight bacterium as well as other disinfectants ( such as bleach , Pine Sol , and Lysol ) did .
It enhances seed germination by eliminating fungi.
ANorth Carolina State University studyby Robert M. Jetton and W. Andrew Whittier determined that seeds of Atlantic white cedar soaked in atomic number 1 peroxide for 1 hour before their sowing germinated at a much higher rate than cum not soaked or soaked in other sterilizing root . The author of the study remark that “ fleece seeds in hydrogen peroxide is known to be effective for sterilizing ejaculate coat infect with saprophytic and pathogenic fungus . ” Of course , only type of seeded player that oft are infected with fungi would require such a “ bathing tub . ”
It cleans the surface of seed-starting mix.
If white mold appears atop yourseed - start mixwhile you are in the summons of starting seeds , you’re able to spray the control surface with a body of water / hydrogen peroxide solution to eliminate the fuzzy interloper . Also , should your seedling begin stagger over due todamping - off disease , you may want to cloud their soil mixture with a diluted hydrogen hydrogen peroxide spray for plant . This can help turn back the mass murder by controlling the fungus that do it . germ - start mixture often are hygienise anyway ; if so , you may not be killing any good bacterium in the cognitive process .
It adds oxygen to flooded hypoxic soil.
Although atomic number 1 peroxide adds no nutrients to the soil , make it useless for distinctive fertilization , it is sometimes used in oxygen fertilization . AUniversity of Floridaarticle notes that the effect of saltwater flooding of works often is that “ air in the soil is replaced by saline water . ” As a result , not enough oxygen reach the flora etymon , and the plant can not support the “ aerobic respiration of the ascendant . ” The authors take down that adding even a small amount of atomic number 1 peroxide when irrigating those plants might be enough to save them .
Applying Hydrogen Peroxide to Soil
To merge up a hydrogen peroxide solution for plants vulnerable to damping off , combine 1 tablespoonful of hydrogen peroxide with 1 quart of water . ( Use the distinctive 3 percent hydrogen peroxide from your pharmacy as your garden hydrogen hydrogen peroxide . ) For combating mold , mix 4 tablespoons of hydrogen peroxide per dry pint of body of water .
Whenwatering plantswith H hydrogen peroxide , either mist the Earth’s surface of the seed - starting admixture with your solution orwater the containerfrom the bottom with that resolution until it dampen the surface . Just keep in mind that the consequence of hydrogen peroxide do n’t last long . So , for seedling specially prostrate to damping off , you might demand to apply raw treatments on a steady basis .
To tote up O to hypoxic soil , the University of Florida recommends that you apply only 1 teaspoon of peroxide per gallon of H2O whenever youwater affected plants .

Avoid Spraying Hydrogen Peroxide on Foliage and Roots
As for apply hydrogen peroxide on plant , it ’s good to avoid that . AsNick Goltz , director of the University of Connecticut Plant Diagnostic Laboratorynotes , “ H peroxide does desex surfaces and can reduce bacteria and some fungi . But the rapid reaction that throw hydrogen peroxide its sterilizing properties occur almost immediately after come in impinging with other chemical compound . This does not allow hydrogen peroxide to move throughout a plant life . ”
This mean that its exercise will not affect most pathogens ( organism that cause diseases ) if the fungi or bacteria are in a plant life ’s tissue paper rather than on its outside . “ use hydrogen hydrogen peroxide to a fault or improperly may even makeplant health issuesworse by drying surfaces and killing good microbes , ” says Goltz .
You ’ll also want to ward off using undiluted hydrogen peroxide for tooth root rot , as is sometimes recommended . A written report done onmoth orchidsproved that even a 3 - minute pic to that compound could damage roots , and the peroxide did little to subdue algae population around the roots .

Disinfecting Garden Tools With Hydrogen Peroxide
To disinfect garden shaft and supplies such aspruning shearsand planting flats , imbue them in a solvent of 1 part 3 per centum hydrogen hydrogen peroxide to 4 parts water .
For cleaning produce , Seattle Times columnist Teresa Graedonrecommends that you apply a food - grade form of 3 percent peroxide rather than the typical drugstore product . add together only about ¼ to ½ cupful of it to a Imperial gallon of water system , and soak produce for 10 to 20 minutes , being sure to rinse it with clean water afterward .
Althoughdrugstore peroxideshould cultivate well enough for hobby nurseryman , there also are stronger types of gardening hydrogen hydrogen peroxide uncommitted for professional grower . In those , the peroxide often is mix with other ingredients and in the main used for glasshouse sanitation .
