Propagation of Ischyrolepis Saxatilis Esterh.

Ischyrolepis saxatilis Esterh., also known as rock sword fern, is a rhizomatous perennial plant commonly found in rocky areas, cliffs, and canyons. It's a hardy plant that adapts well to different environmental conditions. To propagate this plant, there are two main methods: spores and division.

Propagation by Spores

The spores of Ischyrolepis saxatilis Esterh. are produced in sori, which are small brown bumps found on the undersides of the fronds. To propagate the plant using spores, follow these steps:

1. Choose a healthy frond and cut it at the base using sterilized pruning shears.
2. Place the frond in a paper bag and let it dry for a few days to allow the spores to mature.
3. Shake the frond over a piece of paper to collect the spores.
4. Mix the spores with a fine-textured substrate such as peat moss and perlite.
5. Moisten the mixture and cover it with plastic wrap or a clear plastic lid to maintain moisture and humidity.
6. Place the container in a warm, bright location but away from direct sunlight.
7. After a few weeks, the spores will germinate and will develop into small, green heart-shaped plants called gametophytes.
8. When the gametophytes produce their own fronds, they can be transplanted into individual containers and grown until they are large enough to be planted in the ground.

Propagation by Division

Division is the easiest and most common method of propagating Ischyrolepis saxatilis Esterh. This method involves separating the rhizomes or underground stems of the plant and replanting them as individual plants. Follow these steps to propagate the plant by division:

1. Dig up the entire plant or clump in late winter or early spring when the plant is dormant.
2. Divide the clump into smaller sections using sterilized pruning shears or a sharp knife. Each section should have at least one or two healthy fronds and a portion of rhizomes.
3. Plant each section in well-draining soil and water thoroughly.
4. Place the newly planted sections in a shaded area and keep them moist but not waterlogged.
5. After a few weeks, the plant should start producing new fronds, indicating that it is establishing new roots.
6. Once the plant is established, it can be transplanted into its permanent location.

Propagation of Ischyrolepis saxatilis Esterh. is relatively easy with the right techniques. Whether you choose to propagate the plant by spores or division, it's important to keep the soil moist and provide the plant with adequate light and humidity to ensure successful propagation.
