Pocket Botanist
Check these first
- Inspect the undersides of the leaves for fungal growth.
- Check if the soil is soggy or waterlogged.
- Assess if the plants are crowded too closely together.
Likely causes
Fungal Leaf Spot
Most likelyHow to tell: You will see dark, circular spots that may have a yellow halo around them. These often appear when the plant is crowded or the weather is damp.
What to do: Remove the affected leaves immediately to stop the spread. Improve airflow by spacing out your plants and avoid overhead watering to keep the foliage dry.
Overwatering
PossibleHow to tell: The spots might look water-soaked or mushy rather than dry and papery. This often happens if the soil stays soggy for more than a week.
What to do: Let the top inch of soil dry out completely before you water again. Ensure your pot has drainage holes so excess water can escape.

When to worry
If the spots are spreading rapidly to every leaf, you should act quickly to save the plant. A few small spots on older leaves are usually nothing to worry about.
Stopping it coming back
Water at the base of the plant rather than over the leaves, and ensure your morning glory gets plenty of direct sunlight.
