What are the places that ferns are grown naturally? Actually, all the plants have natural growth habitats, but for the indoor decorative purposes, we have to acclimatize those plants to a new environment. Providing the same conditions as natural, we can make a better growing healthy fern plant. So let’s see the factors that need to better growth.

For a successful growth need a warm temperature, shade and moisture in the growing media are essential. High humidity level is better for good growth. In dry season need to supply water and get wet whole the plant.

Temperature requirement

As I said ferns need a warm condition for better growth. There are tropical and temperate fern varieties. Sometimes temperate varieties need a lower temperature than tropical varieties. Normally 15-24 oC range is better for ferns growth.

Humidity level and water requirement

Ferns are like to grow in a wet environment. Wet substrate is always preferred to grow.  To keep that moisture, the high humidity level is required. Normally it is better 60- 75 % of humidity for good growth. It is better to apply water as a spray. Keep good moisture content in the substrate and do not let the soil completely dry. 

Soil and Soil pH

Most ferns can grow 4-7 of pH and better to maintain 7-8. It is better to use organic matter like compost as the media. Naturally, ferns are growing on decaying substance like compost. Provide the same soil condition for better growth.


Ferns are not growing along.  They need a shade. In a forest, they always grow under a shade condition. They need to protect from direct sunlight. 50- 60 % shade is optimum for good growth.


Propagation of ferns in normally done by seeds. They are spores that can be collected under the leaves. Here is a guide to make a fern seed nursery.

Brown color fern spores should be obtained from one-year-old mature plants. Spores have seen the underside of the mature leaves. Spores should be removed using a brush on to a white color paper. (It is easy to see them) The medium for the fern spores consists with 2.5mm sized leaf mold 1: sand: 1.

A shallow pot can be used and wet it well. Then drainage holes should be covered using concave tile pieces and a layer of dried leaves need to be applied over the tile pieces. This facilitates a good drainage.

The medium should be filled up to 3/4 of the pot and then a 4 mm sized tile layer need to be placed on top of the medium in the pot. Next got wet it well and spores should be spread on the tile layer. After that, the pot should be kept in a water bath and cover with a glass. Then it must be kept under 50% shades to obtain plantlets.

Small plantlets with 4 leaves can be seen after 12 months. After those plantlets can be planted in 5 inch sized Polythene bags with the medium consist of Top soli: 4Leaf mould: 2 Cattle manure: 1 Sand 1: ½ inch Tile: ¼ Charcoal: ¼.

You can spray an N: P: K solution with two weeks interval. It is good to use a liquid fertilizer. It is also good to add organic fertilizer. Most ferns that grow in the forest are growing on decaying plants logs or places with rich organic materials. Therefore it is better to research there natural growing substance and make it artificially for our purpose. So it helps to make a well growing healthy plant. 

Problems with the growth

Plants can be weak, if not supply nutrients. In heavy warm conditions, leaves are turning into yellow. It starts from the base of the leave. Finally, leaves are turned into brown color. It is a good solution to recover this problem by using a sprinkler irrigation system. Plants need a shade condition. If not sun burning patches can occur on the leaves.  There are very low pest attacks on ferns. But mealy bugs and scales damages may occur. Remove those damaged part to stop the disease. In sever, conditions Dimethoate or Diazinon can be used.

What are the other requirements for a better ferns growth?
