Polypodium glycyrrhiza
How to Grow Polypodium glycyrrhiza
Overview
Polypodium glycyrrhiza, also known as licorice fern, is a unique and fascinating houseplant that adds a touch of natural beauty to your home. Originating from the shaded, damp locations of northwestern North America, this summer deciduous fern thrives in similar conditions when cultivated indoors.
Growing Conditions
To ensure your licorice fern thrives, it's essential to provide the right environment. These plants prefer bright, indirect light and temperatures between 60-70°F during the day and a drop to around 55°F at night. They also require high humidity levels, ideally above 50%, which can be achieved by misting the leaves or placing a tray of water near the plant.
Planting & Care
When planting your licorice fern, choose a pot with proper drainage holes and fill it with a well-draining, peat-based potting mix. Gently remove the fern from its nursery pot and place it in the center of the new container. Fill in around the roots with more potting mix, ensuring the base of the fronds are just above the soil surface. Water thoroughly and position your plant in bright, indirect light. Regularly mist the leaves or keep the humidity tray filled to maintain high humidity levels.
Common Problems
One common issue licorice ferns face is overwatering, which can lead to root rot. Be sure not to let the potting mix become soggy, and allow the top inch of soil to dry out between waterings. Additionally, these plants may drop some fronds as they prepare for their summer dormancy period, but don't be alarmed – this is a natural process.
Harvest or Enjoy
While licorice ferns are not typically harvested for culinary purposes like their namesake plant, the common licorice (Glycyrrhiza glabra), they can still provide plenty of enjoyment. The delicate, lacy fronds add an air of tranquility and natural beauty to any indoor space. As your fern grows and spreads its roots,
