Can I save a yellow leaf?

No, once a leaf turns fully yellow, it will not turn green again. It is best to snip it off so the plant can focus energy on new growth.

Is yellowing always a disease?

Not at all. It is most often caused by watering habits or light issues rather than a pathogen.

Check these first

Feel the soil to see if it is soggy.
Inspect the undersides of leaves for fuzzy growth.
Check if the plant is sitting in standing water.

Likely causes

Overwatering
Most likely
How to tell: The leaves feel soft and limp while the soil stays muddy for days. You might see yellowing starting at the base of the plant.
What to do: Let the top inch of soil dry out before watering again. Ensure your pot has drainage holes so extra water can escape.
Downy Mildew
Possible
How to tell: You will see yellow spots on the upper leaf surface that eventually turn brown. Look for fuzzy fungal growth on the underside of the leaves.

When to worry

Worry if the yellowing spreads rapidly across the whole plant. A single yellow leaf at the bottom is usually just the plant aging.

Stopping it coming back

Water only when the top inch of soil feels dry and keep the leaves as dry as possible.
