Here’s How To Spot, Treat, And Prevent Root Rot To Keep It From Wreaking Havoc On Your Plants
Imagine you’re nurturing your garden, expecting it to flourish, but instead, you just find your plants wilting, their leaves turning yellow, and their growth stunted.
If you’ve been diligent with watering and ensuring they get just enough sunlight and nutrients, the culprit often lies beneath the surface. We’re talking about a problem known as root rot.
This sneaky issue can devastate gardens and houseplants alike, but with the right knowledge, it’s thankfully preventable and manageable.
What Root Rot Really Is
Root rot is essentially a death sentence for plants if not caught early. It’s a condition where the roots of a plant start decaying due to overwatering or a fungal infection in the soil.
Healthy roots are usually white and firm, playing a critical role in water and nutrient absorption. When they rot, they turn brown or black, become mushy, and fail to nourish the plant, leading to its eventual demise.
Root rot can be caused by a variety of fungi, but the most common culprits are species of Phytophthora, Fusarium, and Pythium.
Recognizing The Signs
Spotting root rot does require a bit of detective work since its initial symptoms are similar to under-watering or nutrient deficiencies.

You can look out for wilting leaves, yellowing or browning, stunted growth, and a general appearance of unhealthiness despite proper care.
The definitive test, however, is to check the roots themselves. You can gently remove the plant from its pot and inspect the roots. If they’re slimy, discolored, and fall apart easily, root rot is likely the issue.
Treating Root Rot
Now, if you catch it early, you can actually save a plant from root rot. You should start by removing the plant from its pot and washing the roots under running water.
Then, trim away all the rotten roots with a clean, sharp pair of scissors or pruning shears, leaving only healthy tissue behind. Also, be sure to disinfect the shears after use to prevent spreading the fungus.
Afterward, repot the plant in a fresh, sterile potting mix and a clean pot, ideally one that ensures good drainage.
In the beginning, you should also water sparingly to avoid recreating conditions favorable to rot.
Preventing Future Outbreaks
The best way to combat root rot is to prevent it from happening in the first place.
One way to keep your garden root rot-free is by adjusting your watering schedule. After all, overwatering is the leading cause of root rot.
So, make sure you’re not watering your plants too frequently, allow the topsoil to dry out between waterings, and use pots with drainage holes.
Additionally, good drainage is crucial. You should use a potting mix that drains well to avoid waterlogging. Plus, adding perlite or vermiculite can improve soil structure and drainage.
Some plants are also simply more resistant to root rot than others. So, do your research and consider adding these resilient varieties to your garden, especially in areas where drainage is a concern.
Last but not least, remember that fungi can spread through contaminated soil, water, and gardening tools.
That’s why you should always sterilize pots and tools between uses and avoid reusing soil from a plant that suffered from root rot.
