How to grow maidenhair fern? Potted cultivation methods and precautions

Maidenhair fern is one of the more common and widely cultivated green plants, with elegant and varied stems and leaves and a compact plant form, very suitable for small pot cultivation to decorate home windowsills and other places. Maidenhair fern fears dryness and strong light, and must be placed in a spot without direct sunlight for cultivation. Below, the editor will introduce the cultivation methods of maidenhair fern in detail.

The growing environment of maidenhair fern

It likes a relatively shady environment and should not be placed in direct sunlight (indoor fluorescent light intensity is already sufficient for its growth needs). Appropriately increasing air humidity can make ferns grow lushly; the humidity requirement is generally up to 80%. The most suitable temperature for fern growth is 14~25°C, and the most suitable season for fern growth is spring.

Propagation methods of maidenhair fern

The propagation of maidenhair fern mainly uses division propagation and spore propagation. Below we explain these two propagation methods in more detail.

1. Division propagation

It can be done indoors in all four seasons, but generally in early spring in combination with repotting. Take the mother plant out of the pot, cut its rhizome so that each piece carries some rhizome and leaves, then plant them separately in small pots. Cover the rhizome with mixed soil, water, and place in a shady, moist environment for cultivation, and new plants can be obtained.

2. Spore propagation

Place peat and fine sand used as the substrate in an oven for high-temperature sterilization to kill pathogens and weed seeds. Then, put the sterilized soil into a shallow sowing pot. Cut leaves with mature spores, collect the spores and evenly scatter them over the shallow sowing pot, no soil covering is needed, cover with a glass sheet, soak water from the bottom of the pot, keep the pot soil moist, and place in a semi-shady environment at 20~25°C. After about 1 month the spores can germinate into prothallia, and after they grow to fill the pot they can be divided and planted. Note that 1~2 days before dividing and planting, the glass on the sowing pot should be removed for ventilation, so as to avoid plant rot or pest and disease occurrence. In addition, in a warm and humid environment it very easily disperses spores and reproduces on its own.

Cultivation techniques of maidenhair fern

When potting, the pot can be a light-colored glazed pot or clay pot; the pot soil must have good water permeability and aeration. Generally use peat soil or leaf mold rich in humus, then add about 1/3 coarse sand and fine sand, and put in some bone meal. The bottom of the pot should be padded with some broken tiles or coarse sand to facilitate drainage. The rhizome planting depth is 1.5~2.5 cm. Plant in spring or repot and change soil. For potting, commonly use a culture soil mixed with humus soil or peat soil, plus a small amount of river sand and base fertilizer. Change the pot every spring; when changing pots, do not damage the roots, avoid wind, and keep the pot soil moist and the air humidity relatively high. After new branches grow, normal management can begin.

Maidenhair fern likes a warm, humid and semi-shady environment. The suitable growth temperature is 21-25°C during the day and 12-15°C at night. In winter it should be moved into a greenhouse; at temperatures above 5°C the leaves can still remain fresh green, but below 5°C the leaves will suffer frost damage. It likes bright scattered light and fears direct sun. In summer it can be appropriately shaded; long-term strong direct light will cause most leaves to turn yellow and wither. Indoors it should be placed in a bright place; even if placed for 1 year it can still grow normally.

Maidenhair fern likes a humid environment. During the peak growth season it should be watered fully. In addition to keeping the pot soil moist, attention should also be paid to relatively high air humidity; when the air is dry, sprinkle water around the plant. Especially in summer, water 1-2 times a day; if water is lacking, the leaves will shrivel. Avoid watering so that the pot soil alternates between dry and wet, which easily turns the leaves yellow. Apply thin liquid fertilizer 2-3 times a month; when fertilizing, do not contaminate the leaf surface, so as to avoid leaf rot. Because maidenhair fern likes calcium, the pot soil should be supplemented with an appropriate amount of lime and crushed eggshells; frequently applying calcium fertilizer will give better results. In winter reduce watering and stop fertilizing.

Potted maidenhair fern often suffers from leaf blight. In the early stage, Bordeaux mixture can be used for control; in severe cases, a 1000~1500 times solution of 70% thiophanate-methyl can be used for control. If scale insects harm the plant, a 1000 times solution of 40% omethoate can be used for control.

Four-season management of maidenhair fern

The low-temperature period in winter and the high-temperature period in summer are its growth-stopping seasons; try not to fertilize, and in summer increase the frequency of spraying water on the leaves. Spring and autumn are the growing seasons for ferns, and an appropriate amount of fertilizer should be applied.

1. Spring and autumn management

Spring and autumn are the growing seasons for ferns; thin fertilizer can be applied according to need and growth conditions. If you want to grow a large pot, after changing to a large pot you can fertilize once a week. The fertilizer concentration should be low, for example 0.1% compound fertilizer (preferably imported or special flower fertilizer) or leachate. At the same time maintain humidity, spray water on the leaf surface every other morning, and water thoroughly once a week.

2. Summer management

Maintain ventilation, spray water on the leaf surface once each in the morning and evening every day. If the leaf surface appears wilted at noon, spray water on the leaf surface at any time or spray water around the environment to increase air humidity, so as to ensure good growth. Water thoroughly once every 5 days; of course, you can decide the number of thorough waterings yourself according to the pot soil conditions.

3. Winter management

Try to maintain indoor temperature; keeping the room from freezing is best. From last year's situation, short-term low temperature of -5°C will not cause much harm to it. Spray water on the leaf surface once every 2 days (if indoor humidity is sufficient, not spraying is also fine), and water thoroughly once every 10 days. In winter just keep the pot soil moist; it must not be too wet, otherwise it is prone to freezing damage.

If water management is normal and temperature is normal, a small amount of yellowing leaves at the base is normal old-leaf renewal, and they can be picked off or cut off. If most leaves turn yellow during the growing season, place 10 granules of compound fertilizer in the pot, once a month. If due to improper management all leaves die (for example, wither and die), all dead leaves can be cut off, and the pot placed in a humid, cool environment; after about 2~3 months its ornamental value can recover.

How to grow potted maidenhair fern? Cultivation methods and precautions for potted maidenhair fern

The leaves of maidenhair fern are verdant and dripping with green, small and dense, layer upon layer, and have high ornamental value.

I. Cultivation methods for potted maidenhair fern

1. Soil:Maidenhair fern likes loose, permeable, fertile calcareous sandy loam. For potting, the culture soil can be made by mixing loam, leaf mold and river sand in equal amounts.

2. Watering:Maidenhair fern likes a humid environment. During the peak growth season it should be watered fully. In addition to keeping the pot soil moist, attention should also be paid to relatively high air humidity; when the air is dry, sprinkle water around the plant. Especially in summer, water 1~2 times a day; if water is lacking, the leaves will shrivel. Avoid watering so that the pot soil alternates between dry and wet, which easily turns the leaves yellow.

3. Sunlight:Maidenhair fern likes bright scattered light and fears direct sun. If the light is too strong, the leaves turn yellow and wither or even die. In summer it can be appropriately shaded; long-term strong direct light will cause most leaves to turn yellow and wither. Indoors it should be placed in a dark place with light; even if placed for 1 year it can still grow normally.

4. Temperature:Maidenhair fern likes warmth and is also cold-tolerant. The suitable growth temperature is 21~25°C during the day and 12~15°C at night. In winter it should be moved into a greenhouse; at temperatures above 5°C the leaves can still remain fresh green, but below 5°C the leaves will suffer frost damage.

5. Fertilizing:Apply thin liquid fertilizer to maidenhair fern 2~3 times a month. When fertilizing, do not contaminate the leaf surface, so as to avoid leaf rot. Because maidenhair fern likes calcium, the pot soil should be supplemented with an appropriate amount of lime and crushed eggshells; frequently applying calcium fertilizer will give better results. In winter reduce watering and stop fertilizing.

6. Pests and diseases:Potted maidenhair fern often suffers from leaf blight. In the early stage, Bordeaux mixture can be used for control; in severe cases, a 1000~1500 times solution of 70% thiophanate-methyl can be used for control. If scale insects harm the plant, a 1000 times solution of 40% omethoate can be used for control.

7. Pruning:After entering autumn, as the temperature drops, maidenhair fern enters a slow-growth stage, and old leaves gradually turn yellow; at this time they should be cut off.

II. Precautions for growing potted maidenhair fern

Maidenhair fern should be planted in spring or repotted and soil-changed. When repotting, be careful not to damage the root system, avoid wind, and replace half with new soil. After repotting, keep the pot soil moist and the air humidity suitable. Because the leaves of maidenhair fern grow quickly, during the growing season regularly thin out and cut off some old leaves. When the leaves are too dense, maidenhair fern not only loses its graceful form, but its inner new leaves will also die due to lack of light, easily forming a hollow phenomenon, so timely pruning is needed. During maintenance, if dead leaves are found on maidenhair fern, they should be cut off promptly to keep the plant fresh and beautiful and to help sprout new leaves.

[Editor's concluding remarks]The leaves of maidenhair fern are fine and dense, and have a very good absorption effect on harmful substances in the air, and can be called a “plant purifier”. The above has introduced the cultivation methods and precautions for potted maidenhair fern, hoping it can help everyone!

How to grow maidenhair fern, cultivation methods and precautions for maidenhair fern

Maidenhair fern habits: it likes fertile, relatively water-permeable calcareous sandy loam. For home potting, a mixture of loam, leaf mold and river sand can be used. Maidenhair fern is native to beside flowing streams or on dripping rock walls at an altitude of 100~2800 m, and is an indicator plant of calcareous soil. The suitable growth temperature for maidenhair fern is 21~25°C during the day and 12~15°C at night. As long as the temperature is above 5°C, the leaves will remain fresh green, but below 5°C the leaves will suffer frost damage. Maidenhair fern likes scattered light and fears direct sun. Indoors it should be placed in a bright place; even if placed for 1 year it can still grow normally.

How to grow maidenhair fern in water culture (basic method)

Environment: The environment suitable for maidenhair fern survival should be a dark and humid environment. This plant cannot tolerate cold and drought, and relatively likes to live in acidic soil, but it can also usually be placed for a short time in a place with scattered sunlight, which can make its growth better.

Soil: In terms of soil, the best combination is mainly a culture soil made by mixing half mountain forest soil and half garden soil.

Watering: Maidenhair fern very much likes a high-humidity environment, so in spring, summer and autumn it should be watered 4~5 times a day; in winter it can be reduced to 1~2 times, but it still needs frequent misting to prevent the leaves from being too dry. During the growing period, watering must be kept sufficient.

Fertilizing: Fertilizing is necessary for maidenhair fern. On average, a thin fertilizer needs to be applied once every 2 weeks or so to promote its growth. But grasp the principle of “small amounts, more frequent applications”; a 1000~2000 times dilution of Hyponex or similar is sufficient.

Temperature: Generally, above 5°C the leaves will not show scorched-yellow phenomena, but it also must not exceed 30°C. In water culture, in addition to controlling the indoor temperature, the water temperature must also be controlled; the water temperature should be equivalent to room temperature.

Light: Be sure to shade it, and avoid direct sunlight; the weaker the light, the better. Placement in the bathroom and indoors must not exceed 3 days, then move to a windowsill for 3 days, and pay attention to misting, which can ensure the plant grows well.

Humidity: Summer weather is often too stuffy and hot, and room ventilation is not very good either. At this time indoor air humidity should be increased, and ventilation should be strengthened.

Pruning: When the leaf cluster is too dense, scissors can be used to appropriately prune those old leaves; otherwise, the leaves easily turn yellow, thereby hindering ornamental value.

Water culture propagation of maidenhair fern

First, wash the roots of soil-cultured maidenhair fern clean, and disinfect with potassium permanganate. Then find a container, add clean water, and prepare a nutrient solution in the appropriate ratio (nutrient solution can be bought on the market), or fix it with something at the container mouth or on the water surface. Maidenhair fern is suitable for planting on coral stone; directly place the coral stone in water, and after it survives it grows very well.

Precautions for water culture of maidenhair fern: Coral stone can be bought at shops making rockeries in flower and bird markets; there are many styles, and you can choose one. Before using coral stone, soak it in water to remove salt. In order to make the stone grow moss, it cannot be kept indoors for a long time; let it receive appropriate sunlight. During water culture, do not let the water submerge the head of the maidenhair fern. Replenish water promptly during maintenance, and change the water once every 5~10 days.

Precautions for growing maidenhair fern:

1. Maidenhair fern by nature likes warm, humid and semi-shady cool environments, and very much dislikes direct sunlight, so it is best to place the plant in a place indoors where sunlight does not reach. After all, too much and too strong light easily causes the leaf edges to scorch.

2. Ferns all grow in humid environments, and for maidenhair fern this is naturally no exception. When cultivating, in addition to keeping the soil moist, water mist should also be frequently sprayed on the leaf surface to increase air humidity. When the plant shows yellowing, it is often caused by insufficient humidity. Of course, this may also be caused by frost damage.

3. Every spring it needs to be repotted once, and at the same time dried leaves and old roots should be pruned off. The pot soil should also be changed to fresh, fertile and loose leaf mold, preferably with a small amount of brick crumbs added inside.

Four-season care of maidenhair fern

Spring care of maidenhair fern

Maidenhair fern can be repotted every April. Maidenhair fern likes a shady and humid environment and fears strong light. In early spring, light can be given in the morning and evening, and it can be placed indoors with bright scattered light. Spring is the growing season for maidenhair fern; pay attention to water and fertilizer management. Especially when caring for it indoors, attention should be paid to increasing indoor air humidity; suitable air humidity is the key to growing maidenhair fern at home. In addition, once a month a ferrous sulfate solution can be poured to increase the acidity of the soil, which is not only beneficial to growth but also keeps its leaves verdant.

Summer care of maidenhair fern

In summer maidenhair fern grows normally, but a high-temperature, hot and dry environment is not conducive to its growth. Maidenhair fern should be placed indoors in bright light for care, keep the pot soil moist, water once each in the morning and evening, and frequently mist around it to increase air humidity. When the weather is too hot, do not water or fertilize; fertilizing is usually done in the evening, and water the next morning after fertilizing. This is more conducive to the exertion of fertilizer efficiency. Maidenhair fern fears wind, and should not be placed in front of an electric fan or at an air-conditioner outlet. Rooms with air conditioning have lower air humidity, so the number of mistings should be increased.

Autumn care of maidenhair fern

In autumn maidenhair fern grows normally; pay attention to water and fertilizer management. After the temperature drops in late autumn, attention should be paid to maintaining indoor temperature, gradually reducing the amount of watering, keeping the pot soil moist, and gradually moving it to a place with morning and evening light for cultivation. After the temperature drops, do not fertilize anymore.

Winter care of maidenhair fern

Maidenhair fern is not cold-tolerant, and room temperature should be kept above 5°C. Below 5°C maidenhair fern enters a state of growth stagnation, and the leaves are dark green. The intensity and duration of morning and evening light can be appropriately increased (avoid noon light), watering should be reduced, the pot soil should be kept on the dry side, and no fertilizing should be done.

If the indoor temperature in winter is on the high side, air humidity will be relatively low; pay attention to supplementing air humidity.
