Plants are resilient, but they are also susceptible to environmental stress, pests, and diseases. Catching these issues early is the key to recovery. Here are the most common ailments and how to cure them:

1. Root Rot

Symptoms: Yellowing, dropping leaves, mushy brown stems at the base, and a foul smell from the soil.

Treatment: Stop watering immediately. Remove the plant from its pot, trim away the dark, mushy roots, and repot in fresh, dry, well-draining soil. Ensure your pot has drainage holes!

2. Powdery Mildew

Symptoms: A dusty, white or gray coating on leaves and stems, often looking like flour.

Treatment: Improve air circulation around the plant. Wipe the affected leaves with a damp cloth, and treat with a mixture of water, baking soda, and a drop of dish soap, or use a commercial fungicide.

3. Spider Mites

Symptoms: Tiny, spider-like webs under the leaves and stippled, pale, or yellowing leaves.

Treatment: Spider mites hate humidity. Wash the leaves thoroughly with insecticidal soap or Neem oil, and increase the humidity around your plant.

4. Fungus Gnats

Symptoms: Tiny black flies buzzing around the soil surface.

Treatment: These pests breed in moist soil. Let the top two inches of soil dry out completely between waterings. You can also use sticky traps to catch the adults and a diluted hydrogen peroxide soak to kill the larvae.

5. Leaf Spot (Bacterial or Fungal)

Symptoms: Brown, black, or yellow spots on the leaves, sometimes with a yellow halo.

Treatment: Remove heavily affected leaves to prevent spreading. Avoid getting water on the leaves when watering, and improve air circulation.
