Root rot is a disease that affects the root system of plants, causing it to literally rot. This problem compromises the roots' ability to support the aerial parts of the plant, leading to rapid decline in the stem and leaves.

Symptoms of Root Rot

Symptoms can vary, but the most common include:

• Gradual wilting of the plant.

• Brown spots appearing on the leaves.

• Rotten areas on the stem.

• A distinctive rotting smell from the soil or plant.

• Stunted, slow, and weak growth.

• Yellowing leaves lacking their usual vibrant green color.

Often, the first signs of the disease manifest on the roots. Healthy roots are strong, vigorous, and light-colored (especially young roots). In contrast, diseased roots appear dark, lack new growth, and emit a foul smell. Unfortunately, common pots often do not allow us to observe the roots unless the plant is unpotted.

Treatment of root rot: Can the plant be saved?

By the time symptoms are noticeable, it is often too late to save the plant. In some cases, chemical treatments can be attempted to stop the progression, but success is not guaranteed. This is why focusing on prevention is far more effective and simpler than trying to cure root rot.

Main causes of root rot

In home environments, root rot is most commonly caused by overwatering. Often, we unintentionally create the perfect conditions for the disease by neglecting factors that influence the water-to-root balance.

Key factors include:

1. Amount and frequency of watering: Overwatering or watering too frequently can be fatal.

2. Type of pot:

   • Wide, shallow pots promote better soil aeration.

   • Tall, narrow pots slow down drying.

   • Transparent pots, ideal for plants like orchids, anthuriums, philodendrons, and monsteras, allow root monitoring and faster drying.

   • Oversized pots increase the risk of prolonged water retention.

3. Use of saucers: If left filled with water, they can keep the soil saturated for too long.

4. Soil composition: A non-draining or unsuitable substrate increases the risk of root rot. Each plant has specific needs depending on its species, the season, and its environment.

Prevention: How to avoid root rot

To prevent root rot, it is essential to:

• Understand your plant’s needs: Learn about its water requirements and the most suitable soil type.

• Choose the right pot: Use a pot of the correct size, with drainage holes and, if possible, small feet to encourage water runoff.

• Opt for a draining substrate: Favor well-aerated mixes, particularly for tropical plants like orchids and monsteras.

• Avoid water stagnation: Regularly check saucers and empty them if needed.

• Moderate watering: Ensure the soil feels dry to the touch before watering again.

Conclusion

Root rot is a disease that can often be avoided with proper plant care. Prevention is always better than cure: by paying attention to the specific needs of your plant, the type of pot, and the soil used, you can drastically reduce the risk of root rot and keep your plants healthy and thriving over time.
