Prof. Martin Thorne, Ph.D.Some recommend vinegar for root rot. Do not use it! Its acidity will burn the roots and kill the beneficial soil microbes in your potting soil. I learned this the hard way when my peace lily started deteriorating late last summer after having been soaked in apple cider vinegar.
Root Damage Mechanisms
- Acetic acid burns root tissues on contact
- Disrupts nutrient absorption channels in roots
- Kills mycorrhizal fungi essential for plant health
- Creates toxic soil pH below 4.0
Soil Ecosystem Destruction
- Eliminates beneficial bacteria within hours
- Disrupts natural nitrogen cycling processes
- Causes long-term soil structure degradation
- Creates conditions favoring harmful pathogens
Hydrogen peroxide beats vinegar safely. Dilute 3 percent peroxide 1:3 with water. This slice bereft of an edge will quickly slay pathogens, but won't hurt the roots. I resuscitated an entire collection of orchids by this means. The release of oxygen aids poisoned roots. Use this during repotting.
Chamomile tea is reported to have mild antifungal properties. Brew 4 tea bags in 1 quart of boiling water and allow to cool completely before using. This is to be applied as a soil drench once a week. Plants receive a mild bath, and any fungi may be knocked off their surface in the process. My snake plants loved it.
Cinnamon powder offers good protection. Dust a teaspoon over the exposed roots after pruning. Reapply after watering. This forms a protective barrier against reinfection, and unlike vinegar, it nourishes the soil biology. I do this monthly as a preventative measure.
Use only natural treatments and avoid using vinegar or any other acids around the house. Keep an eye on your plants and note any changes in white roots, which indicate a successful recovery from damage. If you notice any new roots developing quickly, the plants will appreciate your help.
