Culture methods 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.
