You can propagate fox fern primarily through division.
Here's how to propagate fox fern by division:
- Carefully remove the fox fern from its pot.
- Divide the root ball. Cut the root ball in half, and then in half again if desired, ensuring each division has healthy fronds and roots.
- Repot the divisions. Plant each division in its own pot with appropriate potting mix.
- Water thoroughly.
- Care for the new plants. Provide appropriate light, water, and humidity.
