Overwatering or a nutrient gap

Widespread yellowing usually traces back to soggy roots, or a long stretch with no feeding.

Diagnosis

Overwatering or a nutrient gap

What's happening

Yellowing across many leaves at once is most often advanced overwatering on this water-sensitive plant, so the roots are the first thing to check. Occasionally it's a fast grower that has exhausted the nutrients in tired old soil and simply run out of food.

How to fix it

Check the soil and roots first: if they're wet or rotting, treat it as overwatering — dry the plant out, trim the mushy roots, and repot into fresh fast-draining mix. If the roots are firm and it just hasn't been fed in months, resume a balanced liquid fertilizer at half strength every couple of weeks through spring and summer. Zebrina is a hungry, fast grower and greens back up quickly once it's fed.

What fixes it

  • A balanced liquid fertilizer — A balanced liquid feed at half strength restores color and vigor on this fast-growing plant over a few weeks.

This is general guidance based on common symptoms; individual plants vary.
