How do you care for the latest potted maidenhair fern?
Maidenhair fern, also known as wire grass, iron wire grass, etc., is a perennial herbaceous plant of the genus Adiantum in the family Pteridaceae. It is highly adaptable and easy to cultivate, suitable for year-round indoor potted ornamental display. Small pots can be placed on a desk or coffee table, while larger pots can be used to decorate the windowsill, hallway or living room of a shaded room. It is also a good material for cut leaves and dried flowers. Now let us take a look at how to care for potted maidenhair fern!
Growth habits of maidenhair fern
Maidenhair fern prefers loose, well-drained, fertile calcareous sandy loam. For potting, the growing medium can be made by mixing equal parts of loam, leaf mold and river sand. The suitable growing temperature is 21-25°C during the day and 12-15°C at night. At temperatures above 5°C the leaves can still remain fresh and green, but below 5°C the leaves will suffer cold damage. It prefers bright indirect light and is afraid of direct sunlight. Indoors it should be placed in a bright location, and even if left there for 1 year it can still grow normally.
Propagation methods of maidenhair fern
1. Division propagation: Maidenhair fern can be propagated by division indoors in all four seasons, but it is generally done in early spring together with repotting. Remove the mother plant from the pot, cut its rhizome so that each piece has some rhizome and leaves, then plant them separately in small pots, cover the rhizome with mixed soil, water them, and place them in a shady, moist environment for cultivation to obtain new plants.
2. Spore propagation: Maidenhair fern can also be propagated by spores. 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 off leaves with mature spores, collect the spores and evenly scatter them over the shallow sowing pot without covering with soil. Cover with a glass sheet, 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 one month the spores can germinate into prothalli, and once they have filled the pot they can be divided and planted.
How do you care for potted maidenhair fern?
1. Soil: Maidenhair fern prefers loose, well-drained, fertile calcareous sandy loam. For potting, the growing medium can be made by mixing equal parts of loam, leaf mold and river sand.
2. Watering: Maidenhair fern prefers a moist environment. During the peak growing season it should be watered thoroughly. Besides keeping the potting 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 it lacks water, the leaves will shrivel. Avoid letting the potting soil alternate between dry and wet when watering, as this easily turns the leaves yellow.
3. Sunlight: Maidenhair fern prefers bright indirect light and is afraid of direct sunlight. If the light is too strong, the leaves will turn yellow and withered or even die. In summer it can be appropriately shaded; prolonged direct strong light will cause most of the leaves to turn yellow and withered. Indoors it should be placed in a dark location, and even if left there for 1 year it can still grow normally.
4. Temperature: Maidenhair fern prefers 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 cold damage.
5. Fertilizing: Apply dilute liquid fertilizer 2-3 times a month to maidenhair fern. When fertilizing, do not stain the leaf surface, to avoid causing leaf rot. Because of the maidenhair fern's calcium-loving habit, an appropriate amount of lime and crushed eggshells should be added to the potting soil; 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 it can be controlled with Bordeaux mixture, and in severe cases it can be controlled with a 1000-1500 times dilution of 70% thiophanate-methyl. If scale insects harm the plant, it can be controlled with a 1000 times dilution of 40% omethoate.
7. 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.
