How to Grow and Propagate the Bird's Nest Fern

The bird's nest fern is also known as the nest fern, mountain spinach flower, and crown fern. The bird's nest fern likes warm and humid environments. Note that the bird's nest fern cannot tolerate high heat or severe cold, so when the temperature is above 30°C, remember to mist and ventilate more. Although the bird's nest fern is relatively easy to keep, it still needs diffused light in its daily growing environment to grow better. Avoid direct sun exposure or completely dark spots.

The bird's nest fern grows best in medium to low indirect light. These ferns are usually grown for their crinkled leaves, and the light they receive affects how the leaves crinkle. A bird's nest fern receiving more light, for example, will have more wrinkled leaves, while one receiving less light will have flat leaves. But remember, too much light or direct light will cause bird's nest fern fronds to turn yellow and die.

Bird's Nest Fern

I. Planting

For potted bird's nest ferns, peat soil or leaf mold is best. After 2-3 years of growth, the nest fern's plant form opens up and the roots fill the pot, so it can be taken out of the pot, remove some of the dead roots and withered sporophylls at the base, separate the plants, and replant them individually in pots. When repotting in spring, add leaf mold and moss to the pot, along with a little crushed stone.

II. Temperature and Light

The suitable growing temperature for the bird's nest fern is 22-27°C. In summer, provide shade or place it under a large tree in dappled shade to avoid strong direct sunlight; this benefits growth and makes the leaves more glossy. Indoors, place it in a bright spot and do not keep it in a dark place for long periods. In winter, move it into a greenhouse and keep the temperature above 16°C so it continues to grow, but the minimum temperature must not fall below 5°C.

III. Watering and Fertilizing

Besides light, another important aspect of bird's nest fern care is watering. Ideally, all ferns want consistently moist, but not wet, soil. However, part of what makes the bird's nest fern an ideal houseplant is that it will tolerate the soil drying out. This plant does not need the same level of humidity that many other fern species require, making the bird's nest fern more forgiving for the occasionally forgetful houseplant owner than other ferns. Under high temperature and high humidity in summer, new leaves grow vigorously and need more misting; spray the leaf surface thoroughly and maintain higher air humidity, which favors spore germination. As the leaves enlarge, they often cover all the growing medium in the pot, so be sure to water thoroughly through the pot to avoid the plant's leaves drying out and curling from lack of water. Fertilizer should only be given to the plant 2-3 times per year. Even then, fertilizer should only be applied at half strength, and only in spring and summer. Over-fertilizing can cause deformed leaves, brown or yellow spots, or scorched edges.

IV. Propagation Methods

The bird's nest fern can be propagated by spore sowing and by division. Spore propagation is already widely used for commercial mass production. In general, division can be used. When the plant grows larger, small offshoots often appear; in late spring and early summer, before new buds emerge, use a sharp knife to slowly cut away the parts of the plant that need to be divided, then plant them separately. The bird's nest fern produces few offshoots, so the common method of separating young plants is rarely used for division; usually, in late spring, cut a robust plant from the base into 2-4 sections, and shorten the leaves by 1/3-1/2, so that each section has some leaves and rhizome, then pot each one separately to become a new plant; after potting, place it in a spot above 20 with half shade and higher air humidity for care, so the wounds heal as quickly as possible. Keep the growing medium in the pot slightly moist, not too wet, otherwise it easily rots. Once new leaves emerge, it can gradually regain its original form.

The bird's nest fern is an epiphytic fern. If kept indoors, the bird's nest fern will cling to wooden boards, so when growing bird's nest ferns indoors, be sure to prune regularly to prevent them from growing uncontrolled.

Growing, Propagating, and Care Notes for the Bird's Nest Fern

The bird's nest fern is a large shade-loving foliage plant, very suitable for indoor care. Whether hung indoors or grown in pots placed in the living room, meeting room, or study, it has its own distinctive charm. Moreover, the bird's nest fern is also a very effective air purifier; its large, dense leaves can absorb carbon dioxide through photosynthesis and release large amounts of oxygen, making the sealed indoor air fresh, so it is very popular among plant lovers. Below is an introduction to growing methods and care notes for the bird's nest fern.

The potting medium for the bird's nest fern can be mainly leaf mold or peat soil, vermiculite, etc., mixed with a small amount of river sand, or it can be made by mixing fern roots, crushed bark, moss, or crushed brick particles with a small amount of humus soil. In addition, each spring you can add a little crushed lime to the pot, which benefits the growth and development of its offshoots.

During the growing season, the bird's nest fern should be watered thoroughly. Especially in summer, besides frequently watering the growing medium thoroughly, you must also rinse the leaf surface 2 to 3 times a day, and at the same time sprinkle water on the surrounding ground to increase humidity, maintaining higher air humidity in the local environment; this not only increases the gloss of the leaves but is also very beneficial for the germination of sporophylls.

Under high temperature and high humidity in summer, new leaves grow vigorously and need more misting; spray the leaf surface thoroughly and maintain higher air humidity, which favors spore germination. As the leaves enlarge, they often cover all the growing medium in the pot, so be sure to water thoroughly through the pot to avoid the plant's leaves drying out and curling from lack of water.

a. Sowing Spores

In spring, first mix fine sand and humus soil evenly, sterilize at high temperature, put it into a sowing pot and press flat, then evenly scatter mature spores on the pot soil, then immerse the whole pot in shallow water, using osmotic action to make the pot soil fully moist, cover with glass to keep moisture, and place it in a warm, moist, cool place. The spores will germinate in 7 to 10 days; after about 1 month, green prothallia will grow; after 3 months, when several true leaves have grown, they can be potted for cultivation.

b. Division

This is generally done in mid-to-late April. Choose robustly growing plants, cut the rhizome together with leaves and root clusters into several sections, or pull off the small offshoots growing beside it, cut the leaves by 1/2, and pot them separately, covering with a small amount of leaf mold to create a small environment that is moist, ventilated, and well-drained. Keep the ambient temperature around 25°C; the survival rate is relatively high. Note that the pot soil must not be too wet, to avoid root rot. Division is the most effective propagation method for flower enthusiasts.

c. Tissue Culture

For productive mass propagation, its terminal short stems, young leaves, or spores can be used as explants for rapid tissue culture propagation, allowing large numbers of uniform commercial seedlings to be produced in a short time.

When the plant grows larger, small offshoots often appear; in late spring and early summer, before new buds emerge, use a sharp knife to slowly cut away the parts of the plant that need to be divided, then plant them separately. The bird's nest fern produces few offshoots, so the common method of separating young plants is rarely used for division; usually, in late spring, cut a robust plant from the base into 2-4 sections, and shorten the leaves by 1/3-1/2, so that each section has some leaves and rhizome, then pot each one separately to become a new plant; after potting, place it in a spot above 20 degrees with half shade and higher air humidity for care, so the wounds heal as quickly as possible. Keep the growing medium in the pot slightly moist, not too wet, otherwise it easily rots. Once new leaves emerge, it can gradually regain its original form.

1. The bird's nest fern is suitable for growing in peat soil or leaf mold, and the suitable growing temperature for the bird's nest fern is 22—27 degrees Celsius;

2. Under high temperature and high humidity in summer, new leaves of the bird's nest fern need more misting when growing, and maintaining air humidity favors spore germination;

3. Growing the bird's nest fern does not require too much sunlight; a moderate amount is enough;

4. During the growing season, the bird's nest fern should be watered thoroughly; in winter when room temperature is low, keep the pot soil moist.

The Benefits and Uses of the Bird's Nest Fern and Its Propagation Methods

The bird's nest fern is a new type of foliage plant, and growing it indoors gives a strongly tropical feel. Today we will tell you about the benefits and uses of the bird's nest fern and knowledge about its propagation methods.

The Benefits and Uses of the Bird's Nest Fern

1. Ornamental Value

Ferns, in recent years, have stood out among foliage plants and are deeply loved by people. Internationally, they are popularly used to make large hanging or wall-mounted potted plants, used for hanging decoration in spacious halls, or single bird's nest ferns are attached and fixed at different heights on a tree trunk to form the appearance of a thick old tree, placed in a hall or corridor like a row of ancient trees. An interior decorated with bird's nest ferns has a uniquely distinctive tropical style and can add a touch of vivid natural wildness. It gives people great visual enjoyment and has strong ornamental value.

2. Decorating the Home

The bird's nest fern is a relatively large shade-loving foliage plant, with a full plant form, lush green and glossy leaves, an elegant and unrestrained look, and a strong wild flavor, deeply favored by people. Hanging it indoors also has a distinctive tropical feel. Planted under tropical garden trees or on rockery stones, it can add wild charm. Small potted plants used to decorate a bright living room, meeting room, study, or bedroom also appear small and exquisite, dignified and beautiful.

3. Purifying the Air

It is said that the bird's nest fern placed in a room may release a bit more oxygen than other plants. It cannot remove cigarette odor, but it can absorb harmful gases such as nicotine in smoke, and has a certain air-purifying effect.

4. Market Value

The bird's nest fern has emerald green and glossy leaves, lush green and glossy leaf color, an elegant and unrestrained look, and a strong wild flavor. It is a commonly used leaf material in flower arranging, and the leaves of the bird's nest fern are also an excellent floral material.

5. Edible and Medicinal Value

The uses of the bird's nest fern are mainly reflected in medicine and potted plants. The bird's nest fern can be used as a potted or attached ornamental plant, and its leaves are an excellent floral material, but the bird's nest fern also has edible and medicinal value. The curled young leaves of the bird's nest fern can be stir-fried, boiled, or made into pickles. The bird's nest fern has a slightly bitter nature and flavor and can be used to clear heat and detoxify.

Propagation Methods of the Bird's Nest Fern

The bird's nest fern is usually propagated by spore sowing and division. In March or July-August, scrape mature spores from the leaves (the spores of the bird's nest fern can be seen in the accompanying image in this article), use a mixture of 2 parts leaf mold and 1 part fine sand as the medium, put it into a small flower pot, spread flat and press firm, sterilize, then place it in shallow water to fully moisten, evenly scatter the spores, and cover with a glass slide to keep moisture. At 24°C, with 12 h of light per day and a light intensity of 3000Lx, the spores germinate in about 6-8 days. After 2 months, the antheridia and archegonia of the prothallus mature; at this time, pay attention to misting to create conditions for fertilization. Soon a large number of young sporophytes will be produced, and they can be transplanted when 3-4 leaves have grown.

Because the bird's nest fern rarely produces offshoots, division propagation cannot use the method of separating young plants. Division propagation is simple and easy, but it easily damages the plant shape, and recovery is very slow. In mid-to-late April, cut a robustly growing plant from the base into 4 sections, and shorten the leaves by 1/3-1/2, so that each section has some leaves and rhizome, and pot each one separately to become a new plant. After potting, place it in a spot above 20°C, with half shade and relatively high air humidity, so the wounds heal as quickly as possible. Keep the growing material in the pot slightly moist, not too wet, otherwise it easily rots. Once new leaves grow, it can gradually regain its original form.
