Culture methods and matters needing attention of Dryopteris Dryopteris

maidenhair

Adiantum, Adiantum family, perennial herbs, 0.1-0.6 m tall. Because of its slender stems and color like iron wire, it is named Adiantum. Adiantum is also an indicator of calcareous soil. Due to its fear of dryness and strong light, it must be placed in a place where there is no direct sunlight.

Adiantum fern growing environment

Adiantum like loose permeable, fertile calcareous sandy loam soil, potting soil available loam, decayed leaf soil and river sand mixed equal. Often born in Liushui stream limestone or limestone cave bottom and dripping rock wall, calcareous soil indicator plants, elevation 100-2800 meters.

The suitable temperature for growth is 21-25℃ during the day and 12-15℃ at night. The leaves can keep fresh green when the temperature is above 5℃, but the leaves will be frozen when the temperature is below 5℃. Like bright scattered light, afraid of direct sunlight. It should be placed indoors in a bright place, even if it is placed for 1 year, it can grow normally.

Adiantum fern culture method

soil selection

Adiantum like loose, fertile calcareous soil, families can use: garden soil + decaying soil + sand, according to the ratio of 4:5:1 for mixing. If you want Adiantum fern to grow better, you can sprinkle lime powder in the basin soil to increase calcium.

fertilizing method

Adiantum ferns like fertilizer, but the demand for fertilizer is not large. Spring, summer and autumn for its growing season, 30 days a thin liquid fertilizer. Ferrous sulfate solution can be irrigated 2~3 times a month. Pay attention to proper supplement of calcium fertilizer, so that Adiantum will grow better. Summer temperatures are higher, so try to minimize fertilization. Autumn temperature gradually decreases, mid-October, gradually stop fertilizer. Pay attention to fertilization, the application of fine-mouthed spray pot along the mouth of the pot slowly, do not let the fertilizer touch the leaves, otherwise easy to burn the leaves, affecting the viewing effect.

watering method

Adiantum like warm, semi-shady environment, watering once a day during the growth period, summer is hot, watering once a day in the morning and evening, at the same time watering the leaves and around the pot to improve the air humidity, keep the leaves green. If there is no one at home, you can put the flowerpot on a wet sand table and supplement the water, which can be watered once every 2 to 3 days. In late autumn, winter and early spring, when the temperature is low, the basin soil should be moist, and the surface of the basin soil should not be dried.

lighting requirements

Although Adiantum is a shade plant, it needs a certain amount of light during the growing season. Indoor maintenance, it is best placed on the east or north balcony, the light level is ideal. Summer noon needs shade, morning and evening appropriate light, too strong light will make Adiantum leaves zoom. If it is cultivated on an outdoor balcony, it needs shade at noon all the year round to avoid burning and yellowing of the leaves.

temperature requirements

Adiantum fern grows at 15~20℃, and leaves can keep fresh green only when the temperature is not lower than 5℃ in winter. In midsummer, if the temperature is too high, it is necessary to spray water on the plants every day to increase air humidity and cool down.

bingchong prevention

Adiantum is mainly harmful to leaf blight, which can be controlled by spraying Bordeaux mixture for 1~2 times at the initial stage of disease. Insect pests have scale insects, available 50% malathion 1500 times solution, or 2.5% deltamethrin 3000 times solution spray kill.

pruning method

Over-dense leaf clusters are not conducive to the germination of new leaves. They can be pruned properly in autumn to remove some old leaves and yellow leaves in order to keep the plants fresh and beautiful.

Attention to the cultivation of iron fern

Adiantum should be planted in spring or changed pot soil. When changing pots, pay attention not to hurt the roots, avoid wind blowing, and replace half of the new soil. After changing pots, keep the soil moist and the appropriate air humidity. Because Adiantum leaves grow fast, they are often thinned out during the growing season. When the leaves are too dense, Adiantum not only loses its elegant shape, but also the new leaves growing inside will die due to lack of light, which is easy to form hollow phenomenon, so it needs to be pruned in time. When dead leaves are found in the process of conservation, they should be cut off in time to keep the plants fresh and beautiful, and conducive to the germination of new leaves.

Reasons for yellow leaves:

When the pot soil is dry and wet, Adiantum likes a humid environment. In the peak season of growth, it should be fully watered. In addition to keeping the pot soil wet, it should also pay attention to a higher air humidity. When the air is dry, sprinkle water around the plant. Especially in summer, water should be poured 1-2 times a day. If there is water shortage, it will cause the leaves to shrink, resulting in yellowing of the leaves.

Yellow Solution:

The main reason for the yellowing of Adiantum leaves is improper watering, as long as the wrong watering method can be changed, pay attention to keep the pot soil moist environment, according to the season and climate control watering frequency, but pay attention to not too much watering Oh.

The main value of iron fern

medicinal value

Whole grass (bristle grass): light, bitter, cool. Clearing away heat and toxic materials, removing dampness and detumescence, diuresis and relieving stranguria. For dysentery, scrofula, cough due to lung heat, hepatitis, strangulation, snake bite, traumatic injury.

horticultural value

Shade-loving, adaptable, easy to cultivate, suitable for indoor perennial potted viewing. Small potted plants can be placed on the desk, tea table; larger potted plants can be used to decorate the windowsill, aisle or living room of the shady room. Adiantum leaves are also good materials for cutting leaves and dried flowers.

How to raise Adiantum fern cultivation methods and precautions

Adiantum fern is a relatively common plant, its leaves are relatively small, far from the past a little similar to the leaves of coriander. Home breeding Adiantum has the effect of purifying the air, so many people like to buy a pot of breeding. However, when it comes to farming, there are many skills.

How to raise iron ferns

1, basin soil selection first we have to choose this basin soil. The first choice is to mix half of mountain forest soil with half of garden soil.

2, watering fertilization growing season watering should be sufficient to promote its growth and prosperity. Reduce watering in winter to ensure that the pot soil is slightly moist. Low temperature and high humidity are easy to cause root rot.

3, fertilization skills Adiantum fern in winter, because the temperature is low, the overall physiological activity is not strong, therefore, it is best to apply less fertilizer in winter or simply stop fertilization, so as to ensure that the plant in winter, safe winter.

4, placed in the winter after moving indoors in the light dispersion, pay attention not to direct sunlight, to make it safe for winter, room temperature can be kept at about 10℃. In winter, it is placed indoors in the sun. Not cold, when the winter temperature is not lower than 5℃, the leaves will appear cold damage symptoms.

Culture method of Adiantum

1. Soil: Adiantum like loose permeable, fertile calcareous sandy loam soil. When potted, the cultivated soil can be mixed with loam soil, moldy soil and river sand in equal amount.

2, temperature: Adiantum love warm, environmental growth temperature 13~22℃, planting in the south spring is excellent, the north can also, but because Adiantum is not resistant to high temperature, maintenance methods are also different.

3, light: Adiantum love semi-shade environment, do not let Adiantum direct sunlight oh, suitable for growth in semi-shade.

4, watering: Adiantum like wet, growth period to water more, hot weather should be sprayed on the leaves or drenching water, in order to maintain greater air humidity, to maintain clear patterns and green leaves.

5. Fertilization: apply thin liquid fertilizer 2-3 times a month. Don't contaminate the leaves when applying fertilizer, so as not to cause rotten leaves. Due to the calcium-loving habits of Adiantum, the pot soil should be added with proper amount of lime and broken eggshells. The effect of calcium fertilizer will be better. In winter, water should be reduced and fertilizer should be stopped.

6, pest: potted Adiantum fern, often leaf blight occurs, the initial use of Bordeaux mixture control, serious use of 70% methyl thiophane 1000-1500 times solution control, if there are scale insects harm plants, available 40% omethoate 1000 times solution for control.

7, pruning: in the autumn, with the temperature drop, Adiantum into a slow growth stage, the old leaves will gradually turn yellow, then they should be cut off.

Notes on the cultivation of Adiantum

1. Adiantum fern should be planted in spring or replaced with pot soil. When changing pots, pay attention not to hurt the roots, avoid wind blowing, and replace half of the new soil. After changing pots, keep the soil moist and the appropriate air humidity.

2. Because the leaves of Adiantum fern grow rapidly, in the growing season, part of the old leaves are often thinned. When the leaves are too dense, Adiantum not only loses its elegant shape, but also the new leaves growing inside will die due to lack of light, which is easy to form hollow phenomenon, so it needs to be pruned in time.

3. When it is found that there are dead leaves in the process of maintenance, it should be cut off in time to keep the plants fresh and beautiful, and it is conducive to the germination of new leaves.

The breeding method of Adiantum

1. Radistic propagation of Adiantum. Adiantum can be propagated indoors all the year round, but it is generally carried out in early spring combined with changing pots. The mother plants are taken out from the pots, the rhizomes are cut off, so that each plant has part of rhizomes and leaves, and then they are planted in small pots respectively. The rhizomes are covered with mixed soil, and after irrigation, they are cultured in a damp environment to obtain new plants.

2. Spore propagation of Adiantum. Adiantum can also be propagated by spores, peat and fine sand as substrates are placed in an oven for high temperature disinfection to kill germs and weed seeds, then the disinfected soil is placed in a shallow sowing basin, leaves with mature spores are cut, spores are collected and evenly spread in the shallow sowing basin without covering soil, glass sheets are covered on the top, water is soaked from the bottom of the basin, the soil in the basin is kept moist, and the soil is placed in a semi-shade environment of 20-25 DEG C, spores can germinate into prothallus in about one month, When the pot is full, it can be planted separately.

Adiantum fern in the breeding time must pay attention to temperature, light, soil and other aspects. In the cultivation of luck also requires extremely strong pest control. Adiantum breeding methods are many, we can choose a suitable one to carry out, the above introduction, we can learn more about.

How to raise Adiantum, Adiantum cultivation methods and precautions/avoid drying and strong light

Adiantum can not only view leaves, but also raise harmful substances such as formaldehyde and nicotine at home, and the maintenance management method is relatively simple, so more and more people are prepared to raise a few pots at home, so Adiantum is good to raise? How to raise iron fern? Today we will learn about the cultivation methods and precautions of Adiantum fern.

Is the iron fern good to raise?

Adiantum is one of the better plants to raise, it for soil, temperature, moisture, fertilizer requirements are general, but the requirements for light, humidity are higher, to ensure that it is not too dry environment, light is not particularly strong, and then use the right soil, and reasonable watering, fertilization can be raised very well.

How to raise iron ferns

In the growth environment, Adiantum prefer fertile, loose, permeable soil; in the light it likes bright but not too strong light; in the moisture it likes a humid environment; in the temperature its leaves need more than 5 degrees to be green, so we should try to create such an environment for it.

The cultivation methods and precautions of Adiantum

What kind of soil does iron fern use?

The minimum requirement for soil selection is good drainage and porosity, and the most suitable soil has two kinds, the first is garden soil, rotting soil and fine sand configuration, the proportion is 40%, 50%, 10%; the second is peat soil, rotting soil, fine sand mixture, the proportion is 40%, 40%, 20%.

Note: No matter what kind of soil is used, disinfection treatment must be paid attention to before planting. The simplest method is to dry it in the sun for 1-2 days, and if conditions permit, it can be irrigated with carbendazim or potassium permanganate solution to achieve disinfection.

II. Lighting requirements

Adiantum likes bright environment without lack of light, it is more afraid of direct sunlight, so it is best to put it in the east or north windowsill when raising at home, to avoid it being exposed to sunlight. If it is kept in the hospital, it should cover more than 50% of the sunlight in summer.

Note: When the light is too strong, the leaves of Adiantum fern may zoom and dry, so we must not keep it in full light environment, but in the breeding method and precautions of Adiantum fern, we should also pay attention to not lack of light, if the light is too dark, the leaves will become thin and thin, and the ornamental value of the effect and function of Adiantum fern cannot be exerted.

III. Suitable temperature

The most suitable temperature for Adiantum is 10-20 degrees, but as long as the temperature is above 5 degrees, its leaves can remain green, but often below 5 degrees may be frostbite, so keep warm in winter. In summer, more water is needed to lower the temperature.

Note: In autumn or winter, the temperature difference between day and night is large, how to raise Adiantum fern at this time? It is suggested that flower friends move it indoors, not only to control the temperature within the appropriate range, but also to reduce the temperature difference caused by excessive yellowing of Adiantum leaves.

IV. Watering methods

When watering, you should try to keep the soil moist, because Adiantum is a plant that likes a humid environment, so you can irrigate water once every 1-2 days during the growth period. If it is a summer with high temperature, you can irrigate it once in the morning and evening, and you don't need too much watering each time.

Note: If you do not water often, it will lead to dry and curly leaves, so watering should not be more or less. Although watering times are more, but must not let the soil have water, try to sprinkle the way to water.

V. Fertilization techniques

The demand for fertilizer is not high, as long as you can apply thin fertilizer once a month, because Adiantum is an indicator of calcareous soil, so you can apply less calcareous fertilizer when fertilizing, which can make Adiantum grow better.

Note: When the summer temperature is relatively high, it is necessary to stop fertilizing and wait until the temperature is cool before applying organic fertilizer. In winter, fertilizer is generally not needed, especially when the temperature drops below 5 degrees, and fertilizer should not be scattered on the leaves.
