Why are my morning glory leaves turning yellow?

Check these first

Stick your finger into the soil to check for dampness.
Inspect the drainage holes to ensure they are not blocked.
Look at the undersides of the leaves for pests.

Likely causes

Overwatering
Most likely
How to tell: The leaves turn yellow and feel soft or mushy. The soil stays wet for days after watering.
What to do: Let the top 2 inches of soil dry out completely before watering again. Ensure your pot has drainage holes so excess water can escape.
Nutrient Deficiency
Possible
How to tell: The leaves turn yellow while the veins remain green. This often happens in container plants that have used up all the soil nutrients.
What to do: Apply a balanced liquid fertilizer diluted to half strength. Repeat every 2 to 4 weeks during the growing season.

When to worry

If the yellowing spreads rapidly across the whole vine, it is a sign of root stress. It is normal for the oldest leaves at the very bottom of the vine to yellow and drop as the plant grows.

Stopping it coming back

Water only when the soil feels dry to the touch and use well draining potting mix.
