Why are my New York fern's fronds curling?

It is less common for this fern to have curling fronds, but it is almost always a sign of dehydration or heat stress. Check the soil moisture and the air temperature around the plant first.

Check these first

  1. Feel the soil to see if it is dry.
  2. Check if the plant is near a heater or drafty window.
  3. Look for crispy edges on the leaflets.

Likely causes

  1. Underwatering

    Possible

    How to tell: The leaflets curl inward and feel crisp or dry to the touch. The soil will likely be dry and pulling away from the sides of the pot.

    What to do: Water the plant thoroughly until water runs out the drainage holes. Ensure you are watering every 3 to 7 days to keep the soil consistently moist.

  2. Low humidity

    Possible

    How to tell: The fronds curl and turn brown at the edges, especially in winter or near heating sources. The plant looks generally unhappy and brittle.

    What to do: Group the fern with other plants to create a humid microclimate. You can also place the pot on a tray filled with pebbles and water.

When to worry

Curling is a sign of stress that needs immediate attention. If the fronds are brown and crunchy, they will not uncurl and should be removed.

Stopping it coming back

Maintain consistent soil moisture and keep the plant away from dry air sources. Misting the plant or using a humidifier helps keep the fronds supple.
