Can I use a fungicide?

You can use a copper-based fungicide if the infection is persistent. However, improving airflow and watering habits is usually more effective.

Is this contagious to my other plants?

Yes, fungal spores can spread through the air or water splashes. Keep the infected plant away from your healthy ones until it recovers.

Ti Plant: spots, causes and fixes

Check these first

Look for spots on the undersides of the leaves.
Check if the soil is staying wet for more than 10 days.
Ensure the plant is not crowded by other plants.

Likely causes

Fungal leaf spot
Most likely
How to tell: You will see brown or black spots with yellow halos on the leaves. These spots may grow larger if the plant stays wet for too long.
What to do: Remove the affected leaves immediately to stop the spread. Improve air circulation around the plant and avoid getting water on the foliage when you water.
Overwatering
Possible
How to tell: The leaves develop soft, dark spots and the soil stays soggy. This creates the perfect environment for fungal growth.
What to do: Let the top few centimeters of soil dry out completely before watering again. Ensure your pot has drainage holes so the roots do not sit in water.
