How to Propagate Asplenium Bird’s Nest Fern

Propagating ferns is not an easy job and can be a challenge but fun. Commercially most bird nest are 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 sun.

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

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

Leave them alone for a few months, allowing them to grow at their own pace.

Move the sporelings to individual pots, ensuring that the small ferns remain warm and have enough light.

The first real leaves will grow after about a month. With proper care, in just six months, you will have an entire collection of tiny ferns.

Bird Nest Fern Pest or Disease Problems

Asplenium is a fern susceptible to multiple problems. If the leaves of the plant are turning black, curling at the edges, maintain lower temperature and increase humidity.

This generally results from too much heat and lack of humidity.

Sometimes, brown or dark spots can appear on the leaves. This happens when the temperature is too cold or the fern is allowed to stand in cold drafts.

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.

The best approach is to use a toothpick to remove these insects as using an insecticide can harm the plant.

If the leaves start to lose their color, turning pale or white, the fern is probably not getting enough food.

It can happen if the plant receives too much light.

An easy way to tackle the problem is to move the plant to a shadier spot and add liquid fertilizer in the water when watering.
