Underwatering stress
Yellow lower leaves on dry, limp soil mean it's been drying out too far, too often.
Diagnosis
Underwatering stress
What's happening
Nerve plants have shallow roots and thin leaves that can't store water, so repeatedly letting the soil go bone dry stresses the plant. The oldest leaves are sacrificed first — they yellow and crisp — while the whole plant droops and the soil pulls away from the side of the pot.
How to fix it
Water thoroughly until it drains from the bottom, bottom-watering if the soil has gone water-repellent. Then commit to keeping the soil lightly and evenly moist: check it every couple of days, because Fittonia dries out faster than most houseplants and won't tolerate long dry spells. Trim the spent yellow leaves at the stem once the plant has recovered its firmness.
What fixes it
- Self-watering planters — A self-watering pot keeps moisture steady so the oldest leaves stop yellowing from repeated dry-outs.
If that doesn't fix it
This is general guidance based on common symptoms; individual plants vary.
