Pot culture methods and matters needing attention of Dryopteris Dryopteris

Dryopteris is one of the most common and popular green plants in our country. it has beautiful stems and leaves and small plant type. it is very suitable for small potted plants to decorate household windowsills and other places. Dryopteris is afraid of dryness and strong light. Must be placed in a place where there is no direct sunlight for breeding, the following editor will introduce the breeding methods of Dryopteris in detail.

The growing environment of Dryopteris Dryopteris

Like more shady environment, should not be placed in direct sunlight (indoor daylight intensity has been able to meet its growth needs). Properly increasing air humidity can make ferns grow luxuriantly, and the humidity requirement is generally up to 80%. The most suitable temperature for fern growth is 1425 ℃, and the most suitable season for fern growth is spring.

Propagation methods of Dryopteris Dryopteris

The reproduction of Dryopteris is mainly by ramet reproduction and spore reproduction, below our team these two propagation methods are explained in detail.

1. Ramet propagation

It can be used indoors for four seasons, but it is generally carried out in combination with changing pots in early spring. Take the mother plant out of the basin, cut off its rhizome, so that each piece has part of the rhizome and leaves, and then planted in a small basin. New plants can be obtained by covering the rhizome with mixed soil, irrigating and culturing in a damp environment.

2. Spore reproduction

Peat and fine sand as substrates are disinfected at high temperature in the oven to kill germs and weed seeds. Then, put the sterilized soil into a shallow sowing basin. Cut the leaves with mature spores, concentrate the spores and spread them evenly in the shallow sowing basin, without covering the soil, cover them with a piece of glass, soak the basin bottom with water, keep the basin soil moist, and place them in a semi-shady environment of 20: 25 ℃. The spores can germinate into prothalli in about 1 month and can be divided after the basin is full. Note that the glass on the sowing pot should be removed for ventilation 1-2 days before planting, so as not to cause plant rot or diseases and insect pests. In addition, it is very easy to spread spores to reproduce by themselves in a warm, shady and humid environment.

Cultivation techniques of Dryopteris Dryopteris

Pot, the pot can choose light glaze basin and tile basin; basin soil must have good water permeability and ventilation, generally with humus-rich peat soil or rotten leaf soil, and then add about 1 stroke 3 coarse sand and fine sand, and put in some bone powder, and the bottom of the basin should be covered with some broken tiles or coarse sand to facilitate drainage, rhizome planting depth of 1.5 cm 2.5 cm. Plant or turn the pot to change the soil in spring. Humus soil or peat soil is commonly used in potted plants, and a small amount of river sand and base fertilizer are added to form the culture soil. Change the box every spring, do not hurt the root when changing the basin, avoid the wind blowing, and keep the basin soil moist and high air humidity. It can be managed normally after the new branches grow.

Dryopteris prefers a warm, humid and semi-shady environment. The suitable temperature for growth is 21-25 ℃ in daytime and 12-15 ℃ at night. In winter, the leaves can keep fresh green when the temperature is above 5 ℃, but frost injury will occur when the temperature is lower than 5 ℃. Like bright scattered light, afraid of direct sunlight. Summer can be properly shaded, long-term direct light will cause most of the leaves withered and yellow. It should be placed in a brightly lit place indoors so that it can grow normally even if it is placed for 1 year.

Dryopteris likes the humid environment and should be fully watered in the peak growing season. In addition to keeping wet holes in the basin soil, we should also pay attention to high air humidity and sprinkle water around the plants when the air is dry. Especially in summer, water should be watered 1-2 times a day. If there is a lack of water, it will cause the leaves to shrink. Watering taboo basin soil when dry and sometimes wet, easy to make the leaves yellow. Apply thin liquid fertilizer 2-3 times a month, do not stain the leaves, so as not to cause rotten leaves, because of the calcium-loving habits of Dryopteris, basin soil should add appropriate amount of lime and broken eggshell, the effect of regular application of calcium fertilizer will be better. In winter, we should reduce watering and stop fertilizing.

Potted Dryopteris, often with leaf blight, can be controlled with Bordeaux solution at the initial stage, and 70% methyl topiramate 1000-1500 times in severe cases. If the plant is damaged by scale insects, 40% omethoate 1000 times solution can be used for control.

Four Seasons Management of Dryopteris Dryopteris

The period of low temperature in winter and high temperature in summer is its stop-growing season, do not apply fertilizer as far as possible, and the frequency of foliar spraying should be increased in summer. Spring and autumn is the growing season for ferns, which should be fertilized appropriately.

1. Management in spring and autumn

The spring and autumn season is the growing season for ferns. Thin fertilizer can be applied according to needs and growth conditions. If you want to develop a large basin, you can apply fertilizer once a week after changing it into a large basin. Fertilizer concentration should be low, such as 0.1% compound fertilizer (preferably imported or flower-specific fertilizer) or leaching solution. At the same time, maintain humidity, spray water to the leaves every other morning to work overtime, once a week to pour water.

2. Summer management

Keep ventilated, spray water to the leaf surface once every morning and evening, if the leaf surface is shriveled at noon, you can spray water to the leaf surface at any time or spray water to the surrounding environment to increase air humidity to ensure its good growth. Irrigate once every 5 days, of course, according to the basin soil conditions, the number of times of watering.

3. Winter management

It is best to keep the indoor temperature as far as possible and keep the room free from freezing. Judging from the situation last year, a short-term-5 ℃ low temperature will not cause much harm to it. Spray water on the leaves once every 2 days (if there is enough humidity in the room, it's okay if you don't spray), and water once every 10 days. Keep the basin soil moist in winter, not too wet, otherwise it is easy to freeze.

If the water management is normal and the temperature is normal, the yellowing of a small number of leaves at the base belongs to the normal renewal of old leaves, which can be removed or cut off. If most leaves turn yellow in the growing season, you can put 10 grains of compound fertilizer in the basin once a month. If all the leaves die (for example, withered) due to improper management, the dead leaves can be cut off, and the pots can be put in a wet and cool environment, and the ornamental value can be restored in about 2-3 months.

How to raise potted Dryopteris? Culture methods and matters needing attention of Pteridopteris in potted cultivation

The leaves of Dryopteris Dryopteris are green, small and dense, overlapping, and have high ornamental value. At the same time, Dryopteris fern has strong adaptability and easy cultivation, so it is very suitable for indoor planting, which can not only green the environment, but also purify the air. So, how to grow Dryopteris in pots? The breeding methods and matters needing attention of potted Dryopteris are introduced as follows.

Picture: Dryopteris Dryopteris

1. Culture methods of potted Dryopteris Dryopteris

1. Soil: Dryopteris prefers loose, permeable and fertile calcareous sandy loam. when potted, the cultivated soil can be mixed with loam, rotten leaf soil and river sand.

two。 Watering: clematis like the humid environment, the growing season should be fully watered, in addition to keeping the basin soil moist, but also pay attention to high air humidity, when the air is dry, sprinkle water around the plant. Especially in summer, water should be irrigated once or twice a day. If there is a lack of water, it will cause the leaves to shrink. Watering taboo basin soil when dry and sometimes wet, easy to make the leaves yellow.

3. Sunlight: clematis like bright scattered light and are afraid of direct sunlight. If the light is too strong, the leaves will be withered and yellow or even die, which can be properly shaded in summer, and most of the leaves will be withered and yellow if the strong light is directed for a long time. It should be placed in a dark place indoors, and it can grow normally even if it is placed for 1 year.

4. Temperature: Dryopteris likes to be warm and hardy, and the suitable temperature for growth is 21: 25 ℃ in daytime and 12: 15 ℃ at night. In winter, the leaves can keep fresh green when the temperature is above 5 ℃, but frost injury will occur when the temperature is lower than 5 ℃.

5. Fertilization: rarefied liquid fertilizer is applied 2 or 3 times a month, do not stain the leaves, so as not to cause rotten leaves. Because of the calcium-loving habits of Dryopteris, appropriate amount of lime and broken eggshell should be added in the basin soil, and the effect of calcareous fertilizer will be better. In winter, we should reduce watering and stop fertilizing.

6. Insect pests: leaf blight often occurs in potted ferns. Bordeaux solution can be used to control it at the initial stage, and 70% methyl topiramate 1000-1500 times solution can be used to control severe cases. If the plant is damaged by scale insects, 40% omethoate 1000 times solution can be used for control.

7. Pruning: the fern grows slowly as the temperature drops in autumn, and the old leaves will gradually turn yellow, so cut them off.

2. matters needing attention in potted culture of Dryopteris

Dryopteris should be planted or changed in spring. When changing the basin, be careful not to hurt the root system, avoid the wind blowing, and replace half of the new soil. Keep the basin soil moist and appropriate air humidity after changing the basin. Due to the rapid growth of the leaves of Dryopteris Dryopteris, some of the old leaves are often cut off during the growing season. When the leaves are too dense, Dryopteris not only loses its elegant form, but also its new leaves will die due to lack of light, which is easy to form hollow phenomenon and need to be pruned in time. When withered leaves are found in the process of maintenance, Dryopteris should be cut off in time to keep the plant fresh and beautiful and conducive to the germination of new leaves.

[conclusion] Dryopteris has fine leaves and has a good effect on absorbing harmful substances in the air, so it can be called a "plant purifier". The above introduces the cultivation methods and matters needing attention of potted ferns, hoping to help you!

How to raise Dryopteris Dryopteris, the culture methods and matters needing attention

Dryopteris habits, like fertile, permeable calcareous sandy loam, family pot can be made from a mixture of loam, rotten leaf soil and river sand. Dryopteris is native to the flowing stream or dripping rock wall at an altitude of 100,2800 meters above sea level, and is an indicator of calcareous soil. The suitable growth temperature of Dryopteris Dryopteris is 2125 ℃ in daytime and 1215 ℃ at night. As long as the temperature is above 5 ℃, the leaves will remain fresh green, but the leaves below 5 ℃ will be frostbitten. Dryopteris likes to scatter light and is afraid of direct sunlight. It should be placed in a brightly lit place indoors so that it can grow normally even if it is placed for 1 year.

How to cultivate Dryopteris Dryopteris in hydroponics (basic method)

Environment: the environment suitable for the survival of Dryopteris should be dark and humid, this plant can not stand cold and drought, and prefer to live in acidic soil, but it can also be placed in a place with sunlight scattering for a short time. This will make it grow better.

Soil: in terms of soil, the best combination is the semi-mixed culture soil of mountain forest soil and pastoral soil.

Watering: Dryopteris likes high humidity very much, so it should be watered 4-5 times a day in spring, summer and autumn, but it can be reduced to 1-2 times in winter, but it still needs frequent spraying to prevent the leaves from being too dry. Watering must be adequate during the growing season.

Fertilization: fertilization is necessary for Dryopteris. On average, thin fertilizer needs to be applied every 2 weeks or so in order to promote its growth. However, to grasp the principle of "giving more with a small amount", you can use 1000-2000 times dilute solution such as flower clover.

Temperature: generally speaking, when the leaf is more than 5 ℃, the leaf will not be scorched yellow, but it should not exceed 30 ℃. During hydroponic culture, the water temperature should be controlled in addition to the temperature in the room, which should be equal to the room temperature.

Lighting: be sure to shade and avoid direct sunlight. The stronger the light, the better. Toilet and indoor display can not be more than 3 days, and then move to the windowsill for 3 days, pay attention to spray water, can ensure that the plant grows well.

Humidity: the climate in summer is often too muggy, and the room is not well ventilated. At this time, we should improve the indoor air humidity and pay attention to strengthening ventilation.

Pruning: when the foliage is too dense, the old leaves can be properly trimmed with scissors, otherwise, the leaves will easily turn yellow, thus hindering viewing.

Water culture of Dryopteris przewalskii

First of all, wash the roots of Dryopteris cultivated in soil and disinfect them with potassium permanganate. Then find a container to add water, match it with a proper proportion of nutrient solution (which can be bought on the market) or fix it on the mouth of the container or on the surface of the water. The fern should be planted on the coral stone and put the coral stone directly in the water, which will grow well after survival.

Dryopteris hydroponics precautions: coral stone can be bought in a rockery shop in the flower-and-bird market. There are many styles that you can choose. The coral stone should be desalted by soaking before use. In order to let the stone grow moss, can not be kept indoors for a long time, properly accept the sun. When hydroponic culture, the water should not drown the head of Dryopteris. Water is replenished in time during maintenance, and the water can be changed at 5: 10.

Matters needing attention in culturing Dryopteris:

1. Dryopteris prefers warm, humid and semi-cool environments and hates direct sunlight, so it is best to put the plant indoors where the sun is out of reach. After all, too much light can easily cause scorching on the edge of the leaves.

2. Ferns grow in a humid environment, and Dryopteris Dryopteris is no exception. During cultivation, in addition to keeping the soil moist, water mist is often sprayed on the leaves to improve the humidity in the air. When the plant is yellowing, it is often caused by insufficient humidity. Of course, this may also be caused by frost injury.

3. The pot needs to be changed once every spring, and the dried leaves and old roots should be trimmed at the same time. The basin soil should also be replaced with fresh, fertile and loose rotten leaf soil, and it is best to add a small amount of brick dust inside.

Maintenance of Dryopteris przewalskii in four seasons

Maintenance of Dryopteris in spring

Dryopteris can be changed every April. Dryopteris likes a damp environment and is afraid of strong light. It can be illuminated sooner or later in early spring and placed in a room with bright scattered light. Spring is the growing period of Dryopteris, pay attention to water and fertilizer management. Especially in indoor maintenance, attention should be paid to increasing indoor air humidity, which is the key to family breeding of Dryopteris Dryopteris. In addition, ferrous sulfate solution can be irrigated once a month to increase the acidity of the soil, which is not only conducive to growth, but also make its leaves green.

Maintenance of Dryopteris in summer

Dryopteris grows normally in summer, but the high temperature, hot and dry environment is not conducive to the growth of Dryopteris. Should put the iron line fern in the bright light indoor maintenance, keep the basin soil moist, water each time in the morning and evening, often spray around, improve the air humidity. Do not water and fertilize when the weather is too hot. Fertilization is usually carried out in the evening and watered the next morning after fertilization. This is more conducive to the play of fertilizer effect. The iron fern is afraid of the wind and should not be placed in front of the electric fan and the air outlet of the air conditioner. The air humidity of the air conditioned room is lower, so the number of sprays should be increased.

Autumn maintenance of Dryopteris przewalskii

Dryopteris grows normally in autumn, so pay attention to the management of water and fertilizer. After the temperature drops at the end of autumn, we should pay attention to maintain the indoor temperature, gradually reduce the amount of water, make the basin soil moist, and gradually move it to a place with morning and evening light for cultivation. Don't fertilize when the temperature drops.

Maintenance of Dryopteris in winter

Dryopteris is not resistant to cold and should be kept above 5 ℃ at room temperature. The growth of Dryopteris less than 5 ℃ is stagnant and the leaves are dark green, which can appropriately increase the light intensity and time in the morning and evening (avoid noon light), reduce watering, keep the basin soil dry and do not apply fertilizer.

If the indoor temperature is on the high side in winter, the air humidity will be lower, pay attention to replenish the air humidity.
