Does peroxide stop root rot?

Yes, diluted hydrogen peroxide (H₂O₂) can help stop root rot by killing harmful fungi and bacteria, and it adds beneficial oxygen to the root zone, but it's usually part of a larger treatment involving pruning dead roots and improving soil aeration to fully resolve the issue. Using a 3% food-grade solution, diluted further (e.g., 1 part peroxide to 2-4 parts water), is generally recommended for application to the soil or as a root soak after removing mushy, rotten parts.

You should water plants with a diluted hydrogen peroxide solution (about 1 tsp of 3% H2O2 per gallon of water) every second or third watering to oxygenate roots, boost health, and combat root rot or pests, but use sparingly (e.g., every 3-5 days for issues, or monthly for maintenance) as it can harm beneficial microbes and roots if overused, always spray-test first, and let soil dry between treatments. 

What not to put hydrogen peroxide on?

You should not use hydrogen peroxide on open wounds (it hinders healing), electronics, leather, natural stone (marble, granite), waxed surfaces, or delicate/colored fabrics (silk, wool) because it can damage coatings, etch surfaces, bleach colors, or slow cell repair. It also reacts dangerously with certain metals (copper, brass, iron) and shouldn't be mixed with bleach, ammonia, or rubbing alcohol, which creates toxic fumes. 

How do you bring a dying plant back to life?

To revive a dying plant, first diagnose the problem (under/overwatering, light, pests), then trim dead parts, check/improve roots by repotting if rootbound (using fresh, well-draining soil with compost/Epsom salt), adjust light to bright indirect, water correctly (soak if dry, let dry out partially), provide gentle nutrients (like diluted rice water or half-strength fertilizer), and be patient.

What actually causes root rot?

There are two causes for root rot, but the main cause is poorly drained or overwatered soils. These soggy conditions prevent roots from absorbing all the oxygen they require to live. As the oxygen-starved roots die and decay, their rot can spread to healthier roots, even if the soggy conditions have been rectified.

What can I spray on root rot?

Hydrogen peroxide can both kill the fungi and bacteria that cause root rot, sterilise the pot and soil, and restore oxygen to help the remaining roots recover faster. It has so many other uses that I always have a bottle in my plant cupboard (you can use it for household cleaning too).
