How to Propagate Asplenium Bird’s Nest Fern

Propagating ferns is not an easy job and can be a challenge but fun.

Commercially propagation of most bird’s nest ferns is produced from tissue culture.

But many fern lovers grow new plants from spores.

If the plant is mature enough leaves bearing spores may appear on the underside.

Cut them off and dry them for about a week. Make sure the leaves are dry and the side harboring spores faces up so the spores don’t fall off.

Once the leaves are dry, crush them and sprinkle them over a layer moistened peat moss.

Whether you use a tray or a pot, once you have sprinkled the crushed leaves, water gently and cover the container with plastic or glass.

Place it in a warm spot to encourage growth.

Allow lots of indirect light but make sure it does not receive direct sunlight.

Also, it is essential that the soil does not dry out.

Keep in mind that bird nest Asplenium propagates slowly. After about a month, small sporelings may appear.

Again, try to maintain the appropriate temperature and move the plant away from the cold breeze.

Asplenium Nidus is also susceptible to scale insects that may cluster beneath the leaves.
