Common polypody · Polypodium vulgare

Why are my common polypody leaves curling?

It is less common for this fern to have curling leaves, which is usually a sign of low humidity or underwatering. Check the soil moisture first to see if the plant is thirsty.

Check these first

  1. Feel the soil to see if it is dry to the touch.
  2. Check the humidity levels in your room.
  3. Look for any heat vents blowing directly on the plant.

Likely causes

  1. Low humidity

    Possible

    How to tell: The edges of the fronds will curl inward and may become crispy. This is common in homes with dry air, especially during winter.

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

  2. Underwatering

    Possible

    How to tell: The entire frond will curl and look dull or shriveled. The soil will feel dry and pull away from the edges of the pot.

    What to do: Water the plant thoroughly until water drains from the bottom. Maintain a schedule where you check the soil every 3 to 7 days.

When to worry

If the curling is accompanied by browning or crispy edges, the plant is stressed. Minor curling on very old fronds is just part of the natural aging process.

Stopping it coming back

Keep the humidity around the plant high and never let the soil dry out completely.

Questions people ask

Should I mist the leaves?
Misting provides only temporary relief and can encourage fungal spots. It is better to use a pebble tray or a humidifier.
Will the curled leaves uncurl?
Once a frond has curled due to dehydration, it usually will not return to its original shape. Focus on keeping the new growth healthy.
