How to Grow Maidenhair Fern and What to Watch Out For

Maidenhair fern (Adiantum) prefers a warm, humid and semi-shaded environment. The suitable growing 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 below 5°C the leaves will suffer frost damage. It likes bright, diffused light and fears direct sun. In summer it can be shaded appropriately; prolonged direct strong light will cause most of the leaves to turn yellow and wither. Indoors it should be placed in a bright spot; even after being placed there for 1 year it can still grow normally. So, what are the cultivation methods for maidenhair fern?

Cultivation Methods for Maidenhair Fern

◇——1. Propagation——◇

Under ordinary cultivation conditions, maidenhair fern is mainly propagated by division, and can also be propagated by spores.

Division propagation: Usually in spring (early to mid-April), before new buds have sprouted, division is carried out together with repotting. Knock the plant that has filled the pot out of the pot, remove most of the old potting soil, divide it into 2 to several clumps, and cut apart the connected rhizomes, then plant them separately in pots to become new plants.

Spore propagation: After the spores of maidenhair fern mature, they scatter on moist soil and can grow and develop into new plants. Therefore, it is often seen that beside flower pots and under flower stands there are maidenhair fern plants that have propagated and grown on their own; once they reach a certain height they can be transplanted into pots.

◇——2. Soil——◇

Maidenhair fern likes loose, permeable, fertile calcareous sandy loam. For potting, the growing medium can be made by mixing equal parts of loam, leaf mold and river sand.

◇——3. Light——◇

It likes bright, diffused 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 shaded appropriately; prolonged direct strong light will cause most of the leaves to turn yellow and wither. Indoors it should be placed in a dark spot; even after being placed there for 1 year it can still grow normally.

◇——4. Temperature——◇

It likes warmth and is also cold-tolerant. The suitable growing 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 below 5°C the leaves will suffer frost damage.

◇——5. Watering——◇

◇——6. Fertilizing——◇

Apply dilute liquid fertilizer 2-3 times a month. When fertilizing, do not splash the leaf surfaces, so as to avoid causing leaf rot. Because maidenhair fern likes calcium, it is advisable to add an appropriate amount of lime and crushed eggshells to the potting soil; regularly applying calcium fertilizer will give better results. In winter, reduce watering and stop fertilizing.

◇——7. 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 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.

◇——8. Pruning——◇

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

◇——9. Repotting——◇

When potting maidenhair fern, light-colored glazed pots and clay pots can be used. The potting soil must have good water permeability and aeration. Generally, peat soil or leaf mold rich in humus is used, with about 1/3 coarse sand and fine sand added, along with some bone meal. The bottom of the pot should be lined with some broken tiles or coarse sand to aid drainage. The rhizome should be planted at a depth of 1.5-2.5 cm. Planting is done in spring, or the pot and soil are changed then. For potting, a growing medium commonly made by mixing humus soil or peat soil with a small amount of river sand and base fertilizer is used. Change the pot every spring; when repotting, do not damage the roots, avoid wind, and keep the potting soil moist and the air humidity relatively high. Once new branches grow, normal care can resume.

Maidenhair fern likes a humid environment. During the peak growing season it should be watered thoroughly; in addition to keeping the potting soil moist, attention should also be paid to maintaining 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, the leaves will shrivel. Avoid letting the potting soil alternate between dry and wet when watering, as this easily turns the leaves yellow. Apply dilute liquid fertilizer 2-3 times a month. When fertilizing, do not splash the leaf surfaces, so as to avoid causing leaf rot. Because maidenhair fern likes calcium, it is advisable to add an appropriate amount of lime and crushed eggshells to the potting soil; regularly applying calcium fertilizer will give better results. In winter, reduce watering and stop fertilizing. What are the precautions during the process of growing maidenhair fern?

Precautions for Growing Maidenhair Fern

◇——1. Although indoor light does not usually seem too dim, ordinary indoor light is still slightly too dark for maidenhair fern, so indoors it is best to place it in a brightly lit spot.

◇——2. Maidenhair fern likes a cool climate. The growing temperature is between 15°C and 25°C, and the leaf temperature must not be lower than 7°C, otherwise the leaf surfaces may be frostbitten.

◇——3. Maidenhair fern very much likes a high-humidity environment, so in spring, summer and autumn it should be watered 4-5 times a day.

◇——4. Fertilizing is essential for maidenhair fern, but follow the principle of "small amounts, more frequent applications"; a 1000-2000 times dilution of Hyponex or similar is sufficient.

◇——5. Maidenhair fern by nature likes a warm, humid and semi-shaded cool environment, and strongly dislikes direct sunlight.

◇——6. Ferns all grow in damp environments, and for maidenhair fern this is naturally no exception.

◇——7. Repot once every spring, and at the same time prune away dry leaves and old roots.

After reading this article, I believe everyone has gained a deeper understanding of how to grow maidenhair fern and its cultivation methods. As long as everyone follows scientific cultivation methods and cares for it carefully, they can grow a graceful and lovely maidenhair fern. The above is the relevant introduction on how to grow maidenhair fern, its cultivation methods and precautions, and I hope it can be helpful to everyone.

Indoor light does not seem too dim, but ordinary indoor light is still slightly too dark for maidenhair fern, so indoors it is best to place it in a brightly lit spot.
