Root rot occurs when the roots don't receive enough oxygen, usually because of too much water. A parasite called Pythium makes its way in, and needs to be sterilized from the soil! Use peroxide or bleach to do this!
You can treat the roots with a topical fungicide, such as organic Neem oil, or a water and hydrogen peroxide solution. Mix one tablespoon of hydrogen peroxide with one cup of water and spray the roots down well. Hydrogen peroxide can be used to kill off the organisms responsible for root rot.
Wash the pot with a bleach water solution to kill any fungus or bacteria. Dip the roots in a fungicide solution to prevent re-infection. Repot in new, clean potting soil.
with either Daconil® Action™ fungicide (3.5 fl. oz./1,000 ft.2) or Secure® Action fungicide (0.5 fl. oz./1,000 ft.2) on a 14-day interval are most helpful when take-all root rot symptoms break through.
Most root rot fungi prefer wet soil conditions and some, such as Pythium and Phytophthora, produce spores that can survive for long periods in soil.
Hydrogen peroxide can help to control fungal growth and fungal infection, such as root rot, by preventing the growth of fungi. It can also help kill fungus and bacteria on plant roots.
Hydrogen peroxide kills root rot-causing bacteria and fungi and restores the oxygen balance in the soil which boosts your plants' growth and health. Due to its chemical similarity to water, hydrogen peroxide is one of the safest chemicals you can use in the garden to combat root rot.
It is perfectly safe for plants when properly diluted and used in moderation. Adding hydrogen peroxide to water promotes better growth in plants and boosts roots ability to absorb nutrients from the soil. Diluted 3% peroxide adds needed aeration to the soil of plants and helps control fungus in the soil.
Another product that'll help prevent the spread of root rot is non-flavoured cinnamon. After having removed the dead roots, sprinkle a thin layer onto the healthy tissue before placing into a bed of new compost.
A good place to start is a mix of mild liquid soap and water, sprayed onto houseplants. One teaspoon of soap per litre of water will do the job. It sounds simple, but this formula will treat a lot of common houseplant pests. Add just a teaspoon of bicarbonate of soda and it becomes a great fungicide as well.
Root rot can be identified by the presence of soft, brown roots. The root system of a healthy plant should be firm and white. But when soil is soggy, fungal spores multiply and the fungus starts to spread3, developing in the extremities of the roots first.
Repot with new soil.
Fresh soil will help guarantee that any bacteria or fungus that might have formed will be mostly removed. It'll also supply nutrients that may have been depleted in the old soil and help the plant recover. Keep in mind that the plant is likely already stressed and vulnerable due to root rot.
If you do encounter fungus on your plants, just remember it can be treated and your plants will more than likely recover beautifully. Learn how to recognize powdery mildew and black spot, and how you can prevent and treat them in your own garden.
Apart from being more mindful of how often and how much water you give your plants and plant roots, you can also use a mixture of 3 percent hydrogen peroxide concentration mixed in 1 quart of water once a week to encourage healthy root growth in your plants' roots or treat the spread of root rot and root decay.
If you use a higher concentration of hydrogen peroxide on the foliage of the plant you run the risk of burning it. You could burn the roots, but since it's necessary to kill the root rot-causing bacteria, it's a risk worth taking.
It is not possible to reverse root rot. The treatment of this disease involves removing the affected portions of the plant. Once the rotting or dying parts have been removed, they can then be repotted in fresh soil to give the remaining healthy roots a fresh start.
Best Overall
We chose the Lamisil Terbinafine Hydrochloride Antifungal Cream as our top pick because it works to address a variety of infections, including toenail fungus. The prescription-strength cream comes highly recommended by Dr. Lipner because it can treat athlete's foot before it spreads to the toenails.
Use Tea Tree Oil
Tea tree oil is naturally antifungal and antibacterial. Mix it with any carrier oil like coconut oil or olive oil and dab over the infected area about three to four times a day. This is one of the most effective home remedies to treat fungal infections.
Cut off any diseased roots using a sterile cutting tool like a knife or scissors. You want to make sure that you're cutting off the roots that are black and mushy. After you've cut off any dead roots, we recommend soaking them in an 80:20 solution of water to hydrogen peroxide. Five minutes or so should be sufficient.
Don't just pour straight hydrogen peroxide on the roots. Instead, create a mixture of one part 3% hydrogen peroxide and two parts water, and put it in a watering can or spray bottle. You can either use it while the plant is still in the pot, or after taking it out of the pot.
