Propagating a Frosty Fern Plant

Despite its name and fern-like appearance, the frosty fern plant (Selaginella Krausianna Variegatus) isn't a fern, but a member of the Selaginellaceae, or spike moss family. Although it is a perennial suitable for growing outdoors in the warm climates of U.S. Department of Agriculture hardiness zones 11 to 15, it is most commonly grown as an indoor plant. This easy-to-grow plant is propagated by stems cuttings or divisions.

Instructions

  1. Division

    • 1

      Remove the frosty fern from its container. If the plant is grown outdoors, dig up the plant, working carefully to avoid damaging the roots.

    • 2

      Pull the plant carefully into smaller sections. Ensure that each section has at least three to five healthy roots.

    • 3

      Plant the divisions in planting containers filled with a peat moss-based commercial potting mixture that has been moistened ahead of time. Place the containers in filtered or partial light. Keep the soil moist.

    • 4

      Plant outdoor frosty ferns in well-drained soil and partial or full shade. Water as needed to keep the soil lightly moist. Don't allow the soil to become waterlogged or bone dry.

    Stem Cuttings

    • 5

      Fill a planting container with moist potting mixture.

    • 6

      Cut a 2-to-5-inch length of stem from the tip of a healthy frosty fern plant.

    • 7

      Pinch the leaves from the bottom half of the stem.

    • 8

      Dip the bottom 1 inch of the stem in powdered rooting hormone.

    • 9

      Plant the bare stem in the moist potting soil. Pat the soil lightly around the stem.

    • 10

      Cover the planting container with clear plastic. Place the stem cutting in a warm spot where the cutting is exposed to indirect sunlight. Avoid direct sunlight, which will scorch the stem cutting.

    • 11

      Check the potting mixture every day. If the mixture is dry, open the bag and add a small amount of water, or mist inside the bag. Keep the soil slightly moist, but never soggy.

    • 12

      Watch for new growth to appear, which indicates the cutting is rooted. Remove the plastic, but continue to keep the soil lightly moist.

      Frosty fern benefits from regular fertilization during spring and summer. For indoor plants, use an all-purpose liquid houseplant fertilizer. For outdoor plants, use a dry or liquid fertilizer. Always apply fertilizer according to the rates indicated on the package label.
