Origin

Fittonia verschaffeltii is native to humid tropical forests of South America, where it naturally grows close to the ground under dense vegetation and filtered light.

Recommended substrate

Use a light, humus-rich and free-draining mix containing coco fibre, light organic compost, perlite and a small amount of sphagnum moss.

The growing medium should remain lightly moist without becoming waterlogged.

Watering

Maintain consistent moisture in the substrate.

Fittonia does not tolerate prolonged drying well and may quickly lose turgidity when the substrate becomes too dry.

Humidity

Humidity of approximately 70% to 90% is particularly suitable.

This species thrives in humid environments, which explains its excellent adaptation to terrarium culture.

Temperature

Ideal growing temperature: approximately 20°C to 26°C.

Avoid prolonged cold conditions and cool draughts.

Light

Fittonia 'Joly Josan' prefers soft to medium filtered light.

Avoid intense direct sunlight, which may scorch or fade the foliage.

Growth

Moderate to fast growth under warm, humid and well-lit conditions.

Flowering

The plant may produce small inconspicuous flower spikes, although its main ornamental value is its striking foliage.

Propagation

Propagation is very easy from stem cuttings containing several nodes.

Maintenance

Regular pinching or pruning helps maintain a dense, compact shape.

Remove old or damaged leaves to keep the plant neat and evenly filled.

Fertilisation

Use a very weakly dosed tropical plant fertiliser during active growth.

Avoid excessive feeding, especially in small substrate volumes.
