Root rot might not sound dramatic—but for houseplants, it’s one of the most common (and sneakiest) causes of decline. The good news? It’s preventable, and with the right know-how, you can keep your plants thriving.
Here at Plant Paradise by Gemma, we often help customers who are worried about sad-looking plants. And more often than not, root rot is the hidden culprit. So, let’s break down what it is, how to spot it, and most importantly—how to stop it in its tracks.
🌱 What Exactly Is Root Rot?
Root rot is a fungal or bacterial infection caused by too much moisture around the roots. When roots sit in waterlogged soil for too long, they can’t breathe. As oxygen disappears, harmful pathogens move in, leading to soft, brown, and mushy roots that can no longer support the plant.
Left untreated, the plant struggles to take in nutrients and water—eventually wilting and dying from the roots up.
🚨 Signs to Look Out For
Root rot often hides below the surface, so knowing what to watch for is key:
-
Yellowing leaves
-
Wilting despite watering
-
Leaves dropping unexpectedly
-
Foul-smelling soil
-
Mushy or blackened roots (when checked)
If your plant looks poorly despite regular care, don’t just water more—check those roots!
🪴 What Causes Root Rot?
Root rot is nearly always a result of overwatering, poor drainage, or a combination of both. Some common causes include:
-
Using pots without drainage holes
-
Watering on a schedule rather than checking the soil first
-
Using dense soil that holds too much moisture
-
Letting plants sit in standing water in trays or saucers
Even well-meaning plant parents can fall into this trap, especially during cooler months when plants drink less.
🧑🌾 How To Treat It
Caught early, root rot can be reversed. Here’s what to do:
-
Remove the plant from its pot and gently shake off excess soil.
-
Trim away affected roots using clean scissors—look for brown, black, or mushy sections. Healthy roots are firm and white/tan.
-
Repot the plant in fresh, well-draining soil and a pot with drainage holes.
-
Let the plant rest—don’t water immediately. Give it a few days to settle and dry out a little.
-
Keep the plant in a warm, bright spot (not direct sun) and monitor closely for new growth.
If in doubt, bring it in to us at Plant Paradise by Gemma. We’ll take a look and help you nurse it back to health.
🌿 How To Prevent It in the Future
-
Always check the soil before watering—if it’s still damp, wait.
-
Use a pot with drainage holes and never let water sit in the saucer.
-
Choose the right soil mix for your plant—some need extra drainage (especially succulents).
-
In winter, cut back watering—plants grow slower and need less moisture.
