How Do You Deal with Root Rot?

Root rot is like discovering termites in a house you’ve just renovated—it’s sneaky, destructive, and often worse than it looks. I’ve faced it more than I’d like to admit, and trust me, it can turn a thriving plant into a wilted mess in no time. But don’t panic. There’s a way through it, and it’s not as complicated as it seems.

What Is Root Rot?

Let’s start with the basics. Root rot happens when roots sit in soggy soil too long and fungi or bacteria take over. It’s like drowning, but slower and sneakier. Overwatered pots, poor drainage, or compacted soil are the usual culprits, and once it sets in, it spreads like wildfire underground.

How can you tell? Look for yellowing leaves, stunted growth, or that telltale “I’m dying” droop in your plant. If you pull the plant out and find slimy, brown or black roots that smell like something died, there’s your confirmation.

Can You Save a Plant with Root Rot?

You can, but only if you act like a firefighter at a burning house—fast and with purpose. Here’s how I tackle it every single time:

Step 1: Diagnose and Remove

The first thing I do is yank the plant out of its pot or the ground. Don’t hesitate. If root rot is the issue, leaving it in wet soil only makes it worse. Clean off as much soil as you can from the roots using lukewarm water.

With a pair of sterilized scissors (use rubbing alcohol or bleach), cut away all the damaged roots. Rotten roots won’t recover—ever. Keep only the healthy ones, which are white or light tan and firm to the touch.

Step 2: Treat the Roots

After trimming, I soak the remaining roots in a diluted fungicide or hydrogen peroxide solution (about 1 part peroxide to 5 parts water). This kills lingering pathogens and gives the plant a fighting chance. Some gardeners skip this, but I’ve found it helps, especially in severe cases.

Step 3: Replace the Home

If the plant was in a pot, toss the old soil—don’t reuse it. Pathogens love to linger in damp, contaminated dirt. Get fresh, well-draining soil, preferably one mixed with sand or perlite for added aeration.

For outdoor plants, amend the soil thoroughly. Add compost and organic matter to improve drainage, or consider planting in raised beds to keep water from pooling.

Step 4: Repot or Replant

Repot the plant in its fresh soil and make sure the pot has plenty of drainage holes. For in-ground plants, mound the soil slightly to encourage water to flow away from the roots. Water lightly, just enough to settle the soil around the roots, but don’t overdo it.

“Overwatering is the silent killer of more plants than pests or poor sunlight. When in doubt, water less.”

How to Prevent Root Rot in the Future

Once you’ve wrestled with root rot, you’ll probably do anything to avoid it again. Trust me, I’ve been there. The key is keeping your soil and watering habits in check.

  • Use pots with proper drainage: No drainage holes? Don’t even consider it.
  • Choose the right soil: For houseplants, I always mix in perlite or coarse sand to improve drainage.
  • Water wisely: Let the top inch of soil dry out before watering again. Stick your finger in the dirt—it’s a better gauge than any moisture meter.
  • Be mindful of placement: Outdoor plants in low-lying areas are more prone to soggy conditions. Raise them up or redirect water runoff.
  • Rotate your pots: Indoors, I rotate my pots every few weeks to ensure even light and airflow around the plant.

Some Plants Are Just More Prone

I’ve noticed that certain species—like fiddle leaf figs, succulents, and peace lilies—throw tantrums at the slightest hint of overwatering. If you grow these, tread carefully. They’re the divas of the plant world when it comes to root rot.

Final Thoughts on Fighting Root Rot

Root rot isn’t a death sentence, but it’s a wake-up call. It forces you to pay attention to your plants, your soil, and your watering habits. Once you’ve nursed a plant back to health—and trust me, you can—you’ll start to see the art of gardening differently. And hopefully, you’ll never let those roots drown again.

Frequently Asked Questions about Dealing with Root Rot

What causes root rot?

Root rot is primarily caused by overwatering and poor drainage, which leads to stagnant water around the roots.

How can I prevent root rot?

Ensure proper drainage by using well-draining soil and pots with drainage holes. Water plants only when the top inch of soil is dry to the touch.

How do I know if my plants have root rot?

Look for wilting, yellowing leaves, and a foul odor. Gently remove the plant from its pot to check for brown, mushy roots.

What should I do if my plants have root rot?

Trim away all the affected roots with clean shears, disinfect the pot, and repot the plant into fresh, well-draining soil.

Can I save a plant with severe root rot?

Unfortunately, severe root rot can be difficult to recover from. It's best to propagate any healthy parts of the plant and discard the rest.

How often should I water plants to avoid root rot?

Water your plants thoroughly but infrequently, allowing the soil to dry out between waterings. Frequency may vary depending on your specific plant's needs.

By implementing these steps and keeping an eye on your plants, you can help them live a long, happy, and healthy life in your home. Even if a plant does suffer exposure to root rot, proper care can help it regain its feet and enjoy the prosperity of the garden once again.
