Nephrolepis exaltata Sonata is a compact variety of the popular houseplant fern. Its dense crown of light green, finely ruffled leaves brings a vibrant, fresh atmosphere to the interior. Sonata is suitable for smaller spaces and is one of the best air purifiers.
Watering Ferns require consistently moist substrate – water when the top layer (approx. 1–2 cm) is dry. They do not tolerate complete drying out or waterlogging. Caution: Use room temperature, standing water – chlorine and fluoride from tap water can cause brown leaf tips.
Light Tolerates a wide range of light conditions – from medium indirect to bright indirect light.
Avoid direct sunlight, which can burn the leaves.
It is also ideal for rooms with less natural light.
Temperature and Air
Ideal temperature: 16–24 °C.
Cold: Does not tolerate temperatures below 10 °C or drafts.
Humidity: Requires high air humidity (above 50%). Regularly mist the leaves or place the plant on a tray with moist pebbles. During the heating season, we recommend a humidifier – dry air causes brown leaf tips.
Fertilization During the growing season (spring–summer), fertilize once a month with a liquid houseplant fertilizer at half strength. Completely omit fertilization in winter. Ferns are sensitive to over-fertilization and salt buildup.
Substrate and Repotting Requires a light, humus-rich, and well-drained substrate – a peat mixture with perlite is ideal. Repot in spring when the roots fill the pot, always into a pot only one size larger.
Warning Nephrolepis exaltata is non-toxic to pets and children – it is one of the safe houseplants for homes with animals.
