Signs of Overwatering
Yellowing, mushy tuberous roots pushing out of the pot and a sour smell from the soil mean it has been sitting too wet for too long.
Signs of Underwatering
The feathery needles turn pale, dry out and shed in a fine green rain across the shelf - a classic sign this fern has gone too long between drinks.
Adjusting for the Seasons
Growth almost stops below 15°C, so let the top 3cm dry out in winter rather than sticking to a fixed schedule.
Pro Tip
Despite the name it is not a true fern but a relative of the asparagus vegetable - its tuberous roots store water, so it forgives an occasional missed watering better than most feathery foliage plants.
