Common polypody · Polypodium vulgare

Why is my common polypody growing so leggy?

It is less common for this fern to get leggy, which usually happens when it is reaching for more light. Check your current light levels to see if the plant needs a brighter spot.

Check these first

  1. Move the plant closer to a window with indirect light.
  2. Check the soil moisture to ensure it is not drying out completely.
  3. Rotate the pot every week to encourage even growth.

Likely causes

  1. Insufficient light

    Possible

    How to tell: The fronds will grow long, thin, and sparse as they stretch toward the nearest light source. The plant will look weak and lose its compact shape.

    What to do: Move the fern to a location with brighter, indirect light. Avoid direct sun, which will burn the delicate fronds.

  2. Inconsistent watering

    Possible

    How to tell: The plant may struggle to maintain its structure if it goes through cycles of extreme dryness. This causes the fronds to lose their turgor and droop.

    What to do: Stick to a schedule of watering every 3 to 7 days. Ensure the top inch of soil is slightly dry before you add more water.

When to worry

If the plant is leaning heavily or the stems are becoming very thin, it is time to adjust its environment. Some minor stretching during the winter months is normal.

Stopping it coming back

Provide consistent, medium light and keep the soil evenly moist throughout the year.

Questions people ask

Can I prune the leggy fronds?
Yes, you can trim them back to the base to encourage new, fuller growth. Do this during the active growing season.
Will my fern fill back in?
If you provide better light, the new growth will be much more compact. The old, leggy fronds will not change their shape.
