The main characteristics of the Asplenium Antiquum plant

Growth & Size

Asplenium Antiquum is pretty compact in size- hence making it easier for gardeners to install it indoors. The plant grows to a maximum height of around 80 to 90 cm and a spread of around 45 cm. This means that, on average, these plants have a slower growth rate as compared to other plants.


A healthy-looking Asplenium Antiquum is green. They are arched-shaped and have pointed endings. The length of the leaf is approximately 7 to 8 cm, and the plant’s leaves spread such that it looks like a nest from the center, which is why it is called Birds Nest. 


The plant belongs to the category of ferns, and usually, ferns do not produce flowers. The Asplenium Antiquum is no exception to this rule.


As the plant belongs to a tropical region, it is prone to get attacked by diseases. The disease can be extremely damaging to the plant; therefore, keeping the plant in a place that is shaded and has good air circulation is recommended.

If a disease attacks the plant, the leaves can turn brown. If the plant catches any disease, the leaves can be chopped off to avoid spreading.

How to take care of an Asplenium Antiquum plant


You have to understand the needs of your Asplenium Antiquum plant if you want to grow it to health. The Asplenium Antiquum is a tropical plant, and it needs high amounts of water to grow properly. You should water your plant just enough to keep its soil moist all the time.

We recommend that you water your plant every few days (depending on how quickly the soil dries out) and that you increase the frequency of watering during the summer season.

Be cautious, though; overwatering can damage the plant. To ensure moisture, you can put your fingers in the soil. If the soil is moist, you should wait to water your plant again.

Do not water your plant in the center, as it can increase the chance of rotting roots from the center of the plant.


If you want your Asplenium Antiquum to grow healthy, you must plant it in soil with good drainage. Having poor drainage can result in waterlogged soil, which will create difficulty in the plant’s growth.

Since this plant cannot survive in soggy soil, holes can be made to aid drainage. You can also add sand, pebbles, and grit into the soil, which is good for the roots.


Asplenium Antiquum matures well in warm temperatures ranging from 15 to 20 degrees Celsius. They can grow even when temperatures drop a little bit. However, you must exercise caution; extremely high temperatures can increase the chances of infectious attacks and diseases.


Since this plant is found in tropical areas (where there is shade and no direct exposure to the sun), it is well-adapted to receiving indirect sunlight of low intensity. Do not place your plant under the direct sun, though; bright sunlight can damage the plant’s green leaves.

To expose your plant to the correct intensity of sunlight, we recommend placing it near a large window with a thin, light-permeable curtain.


Low humidity is generally not good for plants, especially for plants that are grown in tropical areas. So, it is not surprising to find that the Asplenium Antiquum plants need high humidity to grow optimally. These plants can survive in any place that has above 50% humidity level.

However, that doesn’t mean that it cannot be grown in a house. If provided with humidifiers, they can even survive there as well.


The Asplenium Antiquum is a plant with a decent height; over time, you will find a branch or two protruding out and ruining its tidiness. To tame the plant, occasional pruning may be needed. It is also important to prune your plant if you notice any dead stems or leaves, as they can hinder your plant’s growth.


Fertilizers can be used occasionally to boost your plant’s growth. For Asplenium Antiquum, you must fertilize them in the spring and autumn seasons once a month. Liquid fertilizer can be used to meet your plant’s nutritional needs.

  6. Please do not place your pot in the bright sun as it can damage the spores.
  7. You will also need to provide humidity to the plant; you can keep your plant covered by a plastic bag.
