How to Treat Root Rot: Save Your Plants Now

Learning how to treat root rot begins with identifying this common plant menace. Root rot occurs when the roots become saturated with excessive water. They become vulnerable to fungi. You may see yellow leaves or wilting. Timely intervention can rescue affected plants.

Screen for root rot quickly. Your plant has a prayer. I saved an orchid once by catching it in time. This quick guide outlines what to look for when finding, fixing, and stopping.

Do not lose hope. Plants bounce back with care. Follow the steps ahead. You will gain confidence. Your green friends will thrive again. Start with knowing the enemy.

What Causes Root Rot

Overwatering drowns the roots in water. They need air to breathe; too much water creates anaerobic conditions. Oxygen disappears, and roots suffocate! I learned that, unfortunately, my fern, which had been in wet soil for days, had mushy roots.

Fungal pathogens thrive in waterlogged soils. Pythium will quickly attack roots weakened by other causes. It moves the caterpillar through the wet soil until it reaches your plants! It can move that quickly in the greenhouse - something I witnessed firsthand. One of my over-watered plants infected three others before the season was through. Keep the soil dry!

With poor drainage, oxygen can't circulate well. Water collects at the bottom, causing roots to rot even when watering is done correctly. Always use a pot with holes, even if no drainage stones are present. Add perlite or even sand to your soil! This simple fix rescued my citrus tree last year!

Fungus gnat spreads root rot, carrying muck from sick plants into healthy ones. Dirty tools do, too. One should always scour the base of each stem cut with sterilized shears and quarantine new plants; otherwise, these silent destroyers will wreak havoc. Preventive measures always pay better than cures.

Signs of Root Rot

Yellow leaves. These usually begin at the bottom of your houseplant and then start making their way up. Your plant backgrounds even after watering. Slow growth. New leaves are small. I once ignored this and lost a prized monstera. Don't delay if you notice these signals.

Dig deeper for root rot! Carefully unpot your plant. Healthy roots are white and firm. Rotten roots are brown or black. They mushily crumble when tested. Do the origins smell of rotten eggs? Uh-oh! This smell never lies.

Symptoms that won't let up. Your plant wilts no matter how much you water it; it's got root problems. Fungus gnats hover around the surface of your soil; root problems. Mold forms on your topsoil; root problems. Your plant is rocking in its pot due to root problems.

Never, ever skip the root inspection. Last year, my peace lily deceived me. The leaves appeared fine, but the roots were soft and mushy. Always check underground whenever anything appears off. Your nose knows. Trust that smell of doom as your last warning.

How to Treat Root Rot

Begin the treatment for root rot by removing your plant from the pot. Gently rinse the roots in lukewarm water between 68-77°F. Thoroughly wash away the soil to expose any areas of rot. I tend to use a soft shower spray for this purpose to avoid damage, although a hose would also be fine. Throw out old soil (don't compost it) to limit the spread of spores.

Before cutting, sterilize your pruning shears in 70% alcohol. Snip rotten roots above the damaged area until you reach the healthy white tissue, disinfecting your blades after each cut through every potentially infected root. That is how I learned to stop the infection from spreading further. As insurance against this fall, take cuttings from healthy stems ahead of your major pruning.

Mix up a fungicide solution according to directions on the label. Soak the roots for thirty seconds to kill the pathogen if the rot is severe; dilute Buxus Blight 1:100. Air-dry the roots for ten minutes before potting. Save the remainder for use on other plants.

Repot into fresh soil mixed with perlite and in a pot that is roughly 20-30% smaller than the old pot. Water the plant lightly, then place it in the shade for 48 hours. My rescued fiddle leaf fig sprang back to life this way, so check for signs of new growth the next day!

Aftercare for Recovery

Check your soil moisture daily by the finger test. Stick your finger into the dirt 2 inches deep. If dirt sticks to your finger, it's not time to water. Only water when your finger comes out dry. That's how my snake plant was saved. Bottom-watering prevents soil compaction. Just sit pots down in a little shallow water for 15 minutes. They will soak it up. Just drain off the extra.

Start plants in dim light for 72 hours. Ten days afterwards, gradually increase the exposure by placing them daily a little nearer to the windows. Maintain a temperature between 68°F and 77°F, which is fairly even. Avoid drafts of cold air and humidify the atmosphere using pebble trays, rather than sprinkling water on the leaves.

Wait four weeks before fertilizing. For the first two feedings, you should use a half-strength solution. 10-10-10 balanced fertilizer may be used monthly while plants are growing. Flush out the soil in the pots every month to prevent salt from accumulating. My orchids bloomed again after that deliberate restart.

Inspect for bright green shoots in about two to three weeks. Gently tug on the plants after a month. If there's resistance, the roots regrow, but if the plants are still somewhat yellow, they have failed. Try to keep the plants entirely isolated for approximately eight weeks. Use some fans to keep air circulation for about 6 hours a day to prevent fungus on your pieces.

Preventing Root Rot

Watering depends on the plants and the season. Succulents require watering every 2 to 3 weeks, whereas tropical plants prefer to be watered once a week. Use half these watering frequencies in winter. Always check to see if the earth is dry by pushing one finger into it, down 2in. Water only when it is dry.

Mix soil for drainage. Most plants prefer a mixture of 60% potting soil and 40% perlite. Ferns thrive in a 70% coco coir and 30% orchid bark mix, Cacti like half sand, 30% pumice, 20% compost. Refresh topsoil every spring.

Choose pots with a minimum of three drainage holes. Terracotta pots reduce the need for watering by a whopping 30%. When selecting containers, go a size or two bigger than the root ball (at least 1 inch/2.5cm bigger on every side), and empty the saucers within 30 minutes after watering (otherwise the roots will sit in the water).

Monthly: Apply natural fungicides. Make an antifungal spray with chamomile flowers steeped in water. Dust soil and plant leaves with cinnamon powder after watering thoroughly. Use a garlic solution once every two weeks (that works against aphids and other pests but is also anti-fungal). Use yellow sticky traps for fungus gnats. Quarantine new plants for three weeks before adding to your collection.

5 Common Myths

Conclusion

Root rot is thus easily prevented or cured by a little care. Adopt three simple safeguards: good *drainage*, careful *moisture*. sanitation, and you decide the fate of root rot.

Check roots occasionally to catch early signs of problems. Every few months, lift your plants out of their pots to check for firm white roots. That's all it took for mine, and I saved my rubber plant last winter by inspecting its roots then. Catching trouble at an early stage gives it little opportunity to spread and promises almost complete recovery.

When plants receive the correct care, they can recover very easily, even after significant damage has occurred. Given the proper care, harmed plants will also recover, but it may take more time and patience. Keep following the instructions we provided; you will have your garden thriving again! Have faith in nature's capability to recover and in your staff's assistance in this process.
