Not enough light

A Nerve Plant that stretches, spaces its leaves far apart, and loses its crisp white veining is almost always under-lit.

Diagnosis

Not enough light

What's happening

Fittonia is a low, spreading groundcover that needs steady bright, indirect light to stay compact and to power its showy white veins. In dim conditions the stems stretch and lean toward the window with long gaps between leaves — a habit called legginess — and the bright veining fades to a duller, washed-out look as the plant strains for light.

How to fix it

Move the plant to a brighter spot with plenty of bright, indirect light, such as a few feet back from an east or north window or filtered south/west light, taking care to avoid harsh direct sun that would scorch it. If your space is genuinely dim, a full-spectrum grow light makes a real difference and is often the only way to bring the crisp veining and compact shape back as new growth comes in.
