How to Grow Maidenhair Fern? A Complete Guide to the Latest Cultivation Methods

The maidenhair fern is one of the more common and widely cultivated green plants. Its stems and leaves are elegant and varied, and the plant is compact, making it very suitable for small pot cultivation to decorate home windowsills and other places. The maidenhair fern fears dryness and strong light, so it must be placed in a spot without direct sunlight for cultivation. Below, the editor will give you a detailed introduction to the cultivation methods for the maidenhair fern.

The Growing Environment of the Maidenhair Fern

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

Propagation Methods for the Maidenhair Fern

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

1. Division propagation

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

2. Spore propagation

Place the 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 off leaves with mature spores, collect the spores and evenly scatter them over the shallow sowing pot; no soil covering is needed. Cover it with a piece of glass, soak water from the bottom of the pot, keep the potting soil moist, and place it in a semi-shady environment at 20-25°C. After about 1 month, the spores can germinate into prothallia, and once they have filled 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 the occurrence of pests and diseases. In addition, in a warm and humid environment, it very easily disperses spores and reproduces on its own.

Cultivation Techniques for the Maidenhair Fern

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

The 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 and green, but when below 5°C the leaves will suffer cold damage. It likes bright indirect light and fears direct sun exposure. In summer, appropriate shading can be provided; long periods of strong direct light will cause most of the leaves to turn yellow and wither. Indoors, it should be placed in a bright spot; even if placed there for 1 year, it can still grow normally.

The maidenhair fern likes a humid environment. During the peak growing season, water thoroughly; in addition to keeping the potting soil moist, also pay attention 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 there is a lack of water, it will cause the leaves to shrivel. When watering, avoid the potting soil being sometimes dry and sometimes wet, which easily turns the leaves yellow. Apply dilute liquid fertilizer 2-3 times a month; when fertilizing, do not contaminate the leaf surface, so as to avoid causing leaf rot. Because the maidenhair fern likes calcium, the potting soil should be supplemented with an appropriate amount of lime and crushed eggshells; frequently applying calcium fertilizer will produce even better results. In winter, reduce watering and stop fertilizing.Potted maidenhair ferns often suffer from leaf blight. In the early stage, Bordeaux mixture can be used for control; in severe cases, a 1000-1500 times dilution of 70% thiophanate-methyl can be used for control. If scale insects harm the plant, a 1000 times dilution of 40% omethoate can be used for control.

Four-Season Management of the Maidenhair Fern

The low-temperature period in winter and the high-temperature period in summer are its seasons of stopped growth; try not to fertilize, and in summer increase the frequency of water spraying 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. According to needs and growth conditions, apply light fertilizer. If you want to grow a large pot, after switching to a large pot, apply fertilizer once a week. The fertilizer concentration should be low, for example 0.1% compound fertilizer (preferably imported or specially formulated for flowers) 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

Keep ventilation, spray water on the leaf surface once each morning and evening. If the leaf surface appears shrunken at noon, spray water on the leaf surface at any time or spray water into the surrounding 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 condition of the potting soil.

3. Winter management

Try to maintain indoor temperature; keeping the room from freezing is best. From last year's situation, a 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, it is fine not to spray), and water thoroughly once every 10 days. In winter, just keep the potting soil moist; it must not be too wet, otherwise it is prone to freezing damage.

If water management is normal and the temperature is normal, a small number of yellowing leaves at the base is normal old-leaf renewal, and they can just 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 all leaves die due to improper management (for example, withering), 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 be restored.
