Maintain nest fern - How to water, fertilize and hibernate properly


Proper care of the nest fern is important for the tropical plant. It is important to consider the needs of the nest fern.

The Asplenium plants occur in around 700 species worldwide. The main distribution area of ​​the nest fern (Asplenium nidus) is Asia, Australia and East Africa. The nest fern differs from the other species due to its funnel-shaped growth form. In its homeland, the nest fern lives up to its name and serves as a home for birds. In addition to the nest fern, the deer tongue fern and the brood fern are popular houseplants in our latitudes.

In its original homeland of Malaysia, the nest fern is the most common type of fern, which grows epiphytically, i.e. on the branches of trees. The ferns can be found there in all tree heights. The fronds are funnel-shaped and are able to collect the rainwater. The plants grow in the mangrove forests on the coasts as well as in the mountain forests of China, at an altitude of almost 2,000 meters. You can find out here how it is possible to offer the nest fern in the living room ideal growth conditions.

Water the nest fern correctly

Pouring requires a bit of tact, as the floor must not dry out, but it should also not cause waterlogging. The root ball may always be slightly moist. The upper layer of earth can dry up a bit between the individual watering.

Do not pour with tap water. This contains too much lime. The better alternative is rainwater or stale tap water mixed with distilled water. If you water with tap water, you should repot your nest fern every year (instructions on planting and repotting the nest fern). The substrate can defy the lime for a certain time, but after about a year the relevant tolerance limit is reached. If you then do not react and replace the soil, you will notice a reduced growth, dried leaves and other deficiency symptoms on your plant.

Since the plants need a high level of humidity, you should spray the nest fern several times a week. Rainwater should also be in the plant sprayer, because calcareous water leaves stains on the fern fronds. A weekly immersion bath also meets the fluid requirements of the plant.

At what point should watering?

This question arises when you look at the nest fern. Should the watering be done in the rosette or directly on the ground? Both are possible. Every room gardener has probably developed his own method. However, you should avoid letting water run down the leaves when watering the nest fern.

How can you ensure high humidity?

As a tropical plant, the nest fern cannot do without a constant high level of humidity. This should be at least 50%, better still a constant 60%. Ferns can therefore be cultivated very well in the bathroom. The room with the highest humidity is the ideal terrain for the nest fern and of course for other representatives of the ferns.

Nothing speaks against cultivation in the living room. Here you can help with some methods to produce a piece of tropical climate in addition to dry heating air:

  • Place the plant in a coaster filled with water
  • spray frequently
  • Set up or hang up the humidifier
  • Set up indoor fountains

Fertilize nest fern properly

The plants' nutrient requirements are rather low. With a liquid fertilizer in low concentration, you can support the growth of the nest fern in spring and summer. You should prefer organic fertilizers to commercially available preparations. The fertilizers should be administered approximately every four weeks. Newly acquired plants are supplied with all the necessary nutrients and do not need to receive any fertilizer in the first year.

Tip:
The nest fern indicates a lack of nutrients by wavy and brown leaf margins. Even when it is dry, the plant reacts similarly and should then be sprayed daily and immersed in water once a week.

Overwinter nest fern properly

The nest fern does not take a winter break in the traditional sense. Cultivation should take place at room temperature all year round. The ideal temperatures are 18 to 25 degrees. The thermometer should never drop below 16 degrees, as this would result in growth disorders. In addition, the plants do not want to be adjusted. This in turn means that the nest fern is confronted with dry heating air. You will be asked a lot in winter, because you must continue to ensure high humidity. Alternatively, the plant can move to the bathroom or bedroom, provided the temperature does not drop below 16 degrees.

You should slightly reduce watering between October and February. You don't have to fertilize the plant in winter either. If you still want to do this, you can give liquid fertilizer in a light concentration every six weeks.
