Welcome home! A little settling-in is completely normal — here’s what to know in week one.
- A dropped leaf or a little droop in the first week is just travel shock — give it a calm, bright spot and time.
- Don’t repot for at least 4 weeks. It ships happy in its nursery pot — just sit that inside your decorative cover.
- Check the plant-specific watering guidance below before giving it a drink — different plants prefer very different levels of dryness.
Light
Bright shade or gentle indirect light — think of the dappled forest floor. A north or east windowsill is perfect. Direct sun bleaches and crisps the fronds quickly.
Watering
Keep the compost lightly moist at all times — check twice a week and water when the surface has just dried. Crucially, water around the edge of the pot, never into the central ‘nest’, which rots if it stays wet.
Humidity & temperature
Humidity is this fern’s love language — bathrooms and kitchens are its natural habitat, and it makes a superb shower-room plant. Keep it above 16°C and out of draughts.
Feeding
A half-strength balanced feed once a month through spring and summer is all it wants — ferns burn easily on full-strength fertiliser.
Repotting & size
Slow-rooting and happy snug — repot only every two to three years when roots fill the nursery pot, into a free-draining peat-free mix with a little extra bark.
Something wrong?
Most problems are fixable — find the symptom below.
Brown, crispy frond tips
Cause
Dry air — the universal fern complaint.
Fix
Move it somewhere more humid and keep watering consistent. Trim crisped tips cosmetically.
Rotting brown centre
Cause
Water sitting in the central rosette.
Fix
Always water at the compost edge, never into the nest. Remove affected material and let it dry out.
Pale, bleached fronds
Cause
Too much direct sun.
Fix
Shift it into bright shade — new fronds will come through a richer green.
Yellowing fronds
Cause
Overwatering or feed burn.
Fix
Let the surface dry between waterings and halve your feed strength.
Fronds not unfurling
Cause
Too cold or too dark.
Fix
Warmth, brightness (not sun) and humidity get the crozier tips moving again.
Brown spots in rows under fronds
Cause
Almost certainly spores — not a pest.
Fix
Neat rows of brown dots are how healthy ferns reproduce. Nothing to treat.
