Can pests cause yellow leaves?

Yes, aphids and whiteflies suck sap from the leaves, which can cause them to yellow and drop. Check the undersides of the leaves carefully for these insects.

Should I cut off the yellow leaves?

Yes, you can snip them off with clean scissors. They will not turn green again and removing them helps the plant focus energy on healthy growth.

Purple bell vine: yellow leaves, causes and fixes

Check these first

Stick your finger one inch into the soil to check for moisture.
Check the drainage holes to ensure they are not blocked.
Look at the underside of the yellow leaves for tiny pests.

Likely causes

Overwatering
Most likely
How to tell: The lower leaves turn yellow and feel soft or mushy to the touch. The soil stays wet for more than 7 days.
What to do: Allow the top inch of soil to dry out completely before watering again. Ensure your pot has drainage holes and never let the plant sit in a saucer of standing water.
Nutrient deficiency
Possible
How to tell: Older leaves turn yellow while the veins remain green, indicating a lack of iron or magnesium. This often happens if the soil pH is off or the plant has been in the same pot for a long time.
What to do: Apply a balanced liquid fertilizer diluted to half strength. If the issue persists, consider repotting into fresh, well draining potting mix.

When to worry

A single yellow leaf at the base of the vine is normal as the plant ages. Worry if multiple leaves across the vine turn yellow at the same time.

Stopping it coming back

Follow a strict watering schedule based on soil feel rather than the calendar. Use a high quality potting mix that drains well.
