Culture methods and matters needing attention of Dryopteris Dryopteris what to do when the leaves are dry and scorched?

Dryopteris is very popular in recent years. Many people like farming very much and look good. What are the breeding methods and precautions of Dryopteris? In the process of breeding, what should I do if the leaves are dry and scorched?

Culture methods and points for attention of Dryopteris Dryopteris:

1. Selection of basin soil

When potted, the pot can choose light glaze basin, tile basin and so on.

Pot soil must have good water permeability and aeration, generally with humus-rich peat soil or rotten leaf soil, and then add about 1 to 3 coarse sand and fine sand, can put in some bone powder, pelvic bottom pad broken tiles or coarse sand, rhizome planting depth is about 2cm.

2. Change the basin

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, keep the basin soil moist and high air humidity, and manage normally after growing new branches.

3. Container selection

Bottle-grown fern chooses a colorless transparent square glass bottle with a smooth surface, which looks good. Mix the peat and fine sand as the cultivation medium and put them in a bottle.

Put the old wall ash at the bottom of the bottle and cultivate the substrate 2~3cm. Do not stick the substrate to the wall of the bottle. Divide the mother plant of Dryopteris into several clumps and plant it carefully into the bottle.

Press the root of the plant and the cultivation substrate, water the bottle cap, and put it in a place where there is no direct sunlight.

Just water it once a month and fertilize it once a few months. Don't put it in a place with a big temperature difference.

4. Proper pruning

After the beginning of autumn, as the temperature drops, the fern enters a slow growth stage, and the old leaves will gradually turn yellow, so they should be cut off.

The ambient temperature should not be lower than 5 ℃ throughout the winter. When the weather gets warmer in spring next year, the plant will grow a large number of new leaves, showing a scene of prosperity.

If it is not watered on time, the plant will produce leaves and branches.

5. Temperature and light

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 ℃.

6. pay attention to watering

Dryopteris likes the humid environment and should be fully watered in the peak growing season. In addition to keeping the basin soil moist, we should also pay attention to the high air humidity and sprinkle water around the plant when the air is dry.

Water should be irrigated 1-2 times a day in summer, the lack of water will cause the leaves to shrink, water bogey basin soil when dry and sometimes wet, easy to make the leaves yellow.

7. Fertilization

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.

8. Overwintering and summer maintenance

The temperature is low in winter and suffers frost damage from late or early frost. Dryopteris prefers warm and humid climate and is not resistant to cold. The suitable temperature for growth is 15 ~ 24 ℃. If the room temperature is above 10 ℃ in winter, the leaves can stay green, and turn black and yellow when the temperature is less than 5 ℃. Too shady, do not see the sun for a long time.

The iron fern is afraid of the summer heat and cannot be exposed to the sun or all shade. It is best to take proper shade in summer, moving outside at night or in the house during the day.

We should fully see the light in winter and increase the air humidity and ventilation in summer.

What if the leaves of Dryopteris are dry and scorched?

1. The cause of the focal edge of the blade.

The leaves of Dryopteris przewalskii are most prone to brown scorched edges, which is a common problem in cultivation. Dryopteris is originally born in wet wall cracks or stone surfaces, and likes to be wet most.

The summer light is strong, to put the fern in the shade environment, the direct sunlight will make the water of the leaves dry quickly, the green will gradually fade, and the focal edge will appear.

2. Focal edge treatment:

After the focal edge, cultivate in the semi-shade, cut off the charred leaves and spray water to the leaf surface and the surrounding ground to avoid the stimulation of strong light.

3. The method of evergreen in four seasons of Dryopteris.

Fully watering and maintaining air humidity during the growth of ①

It is necessary to spray water on the branches and leaves 2 or 3 times a day during the peak growing season to keep the leaves dark green. If the water supply is insufficient or the air is dry, the leaves will turn yellow or scorch the hem.

② does not need much fertilizer, applying thin cake fertilizer and water every 2 to 3 weeks.

The effect is better if a small amount of calcareous fertilizer can be added. However, it should be noted that the leaves should not be stained when watering and fertilizing, otherwise the leaves will be withered and yellow and the ornamental effect will be affected.

③ is a shade plant of the genus Dryopteris, which only needs a little light.

When indoor maintenance is in spring, summer and autumn, it is best to put the flowerpot on the east or north windowsill of the room for maintenance. If you put it outside to cultivate, you must avoid direct sunlight, if you are exposed to strong light, it is very easy to cause the leaf edge to scorch and the leaves to turn yellow.

④ found dead leaves and cut them off in time.

Keep the plant fresh and beautiful, and is beneficial to the germination of new leaves. When the leaves are too dense, the old leaves can be pruned properly every autumn, otherwise the branches and leaves are too cluttered and crowded, it will lead to weak growth and yellow leaves.

⑤ keeps the flowerpot on the south windowsill in winter

And keep the air moist and keep the room temperature above 12 ℃, so that the leaves will grow bright green and lovely.

⑥ change basin

Dryopteris przewalskii grows fast and needs to be changed every spring, with new culture soil added every time.

This is the end of the introduction of the breeding methods and matters needing attention of Dryopteris Dryopteris. The dry leaves and the solution of the coke edge in the process of breeding are also introduced. Come and raise one as soon as possible.

How to raise Dryopteris, how to cultivate Dryopteris and matters needing attention / avoid drying and strong light

Dryopteris can not only observe the leaves, but also raise harmful substances such as formaldehyde and nicotine at home, and the methods of maintenance and management are relatively simple, so more and more people are going to raise a few pots at home, so is it easy to keep them at home? How to raise Dryopteris? Today we will learn about the breeding methods and points for attention of Dryopteris Dryopteris.

Is Dryopteris easy to raise?

Dryopteris Dryopteris is one of the plants that are easy to raise. It has general requirements for soil, temperature, water and fertilizer, but higher requirements for light and humidity to ensure that its environment is not too dry and the light is not particularly strong, and then use suitable soil. And reasonable watering, fertilization can raise very well.

How to raise Dryopteris

In the growing environment, Dryopteris prefers fertile, loose and permeable soil; in light, it likes places where the light is bright but not too strong; in water, it likes a moist environment; in temperature, its leaves need more than 5 degrees to be green, so we should try to create such an environment for it during conservation.

Culture methods and matters needing attention of Dryopteris Dryopteris

What kind of soil does Dryopteris use?

In the choice of soil, the lowest requirement is good drainage and loose, and there are two most suitable soils, the first is to use garden soil, rotten leaf soil and fine sand, the proportion is 40%, 50%, 10%; the second is to use peat soil, rotten leaf soil, fine sand mixture, the proportion is 40%, 40%, 20%.

Note: no matter which kind of soil is used, you must pay attention to disinfection before planting. The easiest way is to dry in the sun for 1-2 days, and if possible, you can use carbendazim or potassium permanganate solution to achieve disinfection.

Second, lighting requirements

Dryopteris likes a bright environment with no lack of light, and it is afraid of direct sunlight, so it is best to keep it in the east or north windowsill when raised at home, so as to prevent it from being exposed to the sun. If you are kept in the hospital, you should block out more than 50% of the sun in summer.

Note: when the light is too strong, the leaves of Dryopteris may become zoom and dry, so we must not raise it in full light, but in the breeding methods and precautions of Dryopteris, we should also pay attention to the lack of light, if the light is too dark will make the leaves thinner, thin, unable to play the efficacy of Dryopteris and the role of ornamental value.

3. Suitable temperature

The most suitable temperature for Dryopteris 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 frostbitten, so keep warm in winter. In summer, you need to spray more water to lower the temperature.

Note: in autumn or winter, the temperature difference between day and night is large, at this time how to raise Dryopteris? It is suggested that flower friends move it indoors, which can not only control the temperature within a suitable range, but also reduce the excessive temperature difference and lead to the yellowing of fern leaves.

Fourth, watering method

When watering, you should try to keep the soil moist, because Dryopteris is a plant that likes a humid environment, so it can be watered once a day or two during the growing period. If it is a hot summer, it can be watered once in the morning and evening, not too much each time.

Note: if often not watered, the edges of the leaves will dry up and curl, so watering should be avoided. Although there are many times of watering, there must be no stagnant water in the soil. Try to water it by sprinkler irrigation.

5. Fertilization skills

The demand for fern on fertilizer is not high, as long as it can be applied with thin fertilizer and water once a month, because Dryopteris is an indicator of calcareous soil, so less calcium fertilizer can be applied when fertilizing, which can make the fern grow better.

Note: when the summer temperature is relatively high, you need to stop fertilization and wait until the temperature is cool before applying organic fertilizer. In winter, there is no need to apply fertilizer, especially when the temperature drops below 5 degrees, and fertilizer should not be sprinkled on the leaves.

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.
