Nephrolepis exaltata ‘Sonata’

Keep the growing medium consistently lightly moist, allowing the surface to begin drying slightly before watering again. Avoid allowing the root ball to completely dry out for prolonged periods, but don't leave the pot sitting in standing water either. Watering may need to be more frequent during warm, bright weather.

Bright, indirect light is ideal for healthy, lush growth. ‘Sonata’ can tolerate somewhat softer light, but avoid deep shade and prolonged harsh direct sunlight, which can scorch and dry its delicate fronds.

‘Sonata’ appreciates high humidity and can struggle in very hot, dry air. Bathrooms and kitchens with suitable light can work particularly well. Keep it away from radiators and drying draughts, while still allowing good airflow around the foliage.

Feed lightly with a balanced houseplant fertiliser around once a month during active growth in spring and summer, following the manufacturer's instructions. Ferns can be sensitive to excessive fertiliser, so avoid overfeeding and reduce feeding during autumn and winter.

‘Sonata’ develops into a dense clump of arching fronds, with fresh growth emerging from the centre of the plant. Repot when noticeably root-bound, moving up only slightly in pot size and using a moisture-retentive but well-draining houseplant mix. Older brown or damaged fronds can be removed cleanly at the base to keep the plant looking fresh.

Nephrolepis exaltata ‘Sonata’ is generally considered non-toxic to cats and dogs, making it a lovely choice for pet-friendly homes. As with any houseplant, it's still sensible to discourage pets from chewing or damaging the foliage.
