Should I use a fungicide?

Fungicides do not work on bacterial infections. Focus on removing the infected parts and keeping the foliage dry.

Is the plant going to die?

If you catch it early and improve the environment, the plant will recover. If the stems turn black and mushy, the infection may be too far gone.

Why does my English Ivy have dark spots on its leaves?

Check these first

Check if the soil is constantly wet.
Inspect the spots for a yellow halo.
Ensure the plant is not crowded by other plants.

Likely causes

Bacterial Leaf Spot
Most likely
How to tell: You will notice dark, water soaked spots that may have a yellow halo. These spots often appear after the leaves have been misted or kept in high humidity.
What to do: Remove and discard all affected leaves immediately to stop the spread. Improve air circulation around the plant and avoid getting water on the leaves when you water.
Overwatering
Possible
How to tell: The soil stays soggy for long periods, which encourages bacterial growth. The leaves may also turn yellow or soft.
What to do: Let the top inch of soil dry out completely before watering again. Ensure your pot has drainage holes so excess water can escape.

When to worry

If the spots are spreading rapidly to new growth, you need to act fast. A single spot might be minor, but a cluster of them indicates a serious infection.

Stopping it coming back

Water only the soil, never the leaves, and ensure the plant has plenty of space for air to move around it.
