Root Rot: It’s Not Always What You Think
You water your plant. Two days later, you notice that the leaves are wilted, soft, and yellowing. Googling the symptoms leads you to sources saying it’s root rot. But that can’t be right—right? You’ve only just watered after two weeks of not watering. The roots couldn’t have deteriorated from rot if it hasn’t been overwatered… right?
Dry Root Rot: The Overlooked Culprit in Houseplant Care
There’s a common misconception that root rot is only caused by overwatering. This belief often pushes plant owners to water their houseplants less frequently, sometimes going weeks without moisture. The logic makes sense: if you water less, you can’t overwater. But in reality, irregular or sparse watering can cause just as much damage—sometimes in a more deceptive way.
This is where dry root rot comes in.
When a plant is underwatered for extended periods, its roots can dry out and die. These dead roots are brittle and no longer absorb water efficiently. When water is finally introduced again, instead of reviving the plant, moisture sits around these decayed roots, creating the perfect environment for fungal and bacterial infections to set in. What you end up with is root rot—but not from too much water. It’s from a combination of dehydration and decay.
How to Spot Root Rot—Wet or Dry
Regardless of whether the cause is overwatering or underwatering, root rot symptoms are fairly consistent:
Wilting or drooping leaves, even after watering
Yellowing, soft, or mushy foliage
A foul, musty odor coming from the soil
Black, brown, or mushy roots when inspected
If you suspect root rot, gently remove the plant from its pot and examine the roots. Healthy roots are firm and white or light tan. If you notice dark, mushy, or hollow-feeling roots, it’s time to act.
How to Treat Root Rot in Houseplants
Remove the Plant from Its Pot: Shake off excess soil and rinse the roots gently.
Trim Affected Roots: Use sterilized scissors to cut off any blackened or mushy roots.
Repot in Fresh Soil: Choose a well-draining potting mix and a clean pot with proper drainage holes.
Adjust Your Watering Schedule: Focus on consistent moisture, not extremes. Let the top inch of soil dry out between waterings.
Improve Air Circulation: Good airflow around the pot can help prevent fungal issues.
At Vick & Vines, we recommend using our curated indoor plant care products, including soil mixes designed to improve drainage and reduce the risk of root rot.
Finding the Right Balance: Houseplant Watering Tips
The key to preventing both overwatering and dry root rot is balance. Here are a few quick tips to keep your plants thriving:
Check Soil Before Watering: Stick your finger one inch into the soil. If it feels dry, it’s time to water. If not, wait a few days.
Use the Right Potting Mix: A chunky, well-aerated soil helps roots breathe and prevents excess moisture buildup.
Choose the Right Pot: Always use containers with proper drainage holes.
Match Watering to the Plant’s Needs: Tropical plants like Philodendron and Anthurium prefer consistent moisture, while succulents and cacti need more drying time.
