How to trim Dryopteris looks good, time / method / post-cutting maintenance management is very important.

In order to make the fern more beautiful, in addition to mastering the correct maintenance skills to make it grow strong and the leaves are thick and green, there is another thing that flower friends should know, that is, pruning, timely pruning can make the plant shape more beautiful. It can also increase air permeability and promote the germination of new buds. It can be said that there are many benefits, so how to trim and look good? The following editor sorted out the pruning methods of Dryopteris shared by flower friends.

How to trim Dryopteris looks good

Does Dryopteris need pruning?

Many flower friends think that as long as the maintenance and management is done, then Dryopteris can grow healthily, but in fact this idea is not entirely correct, because pruning and letting it grow healthily are not contradictory, but can help Dryopteris grow faster. For example, cutting off old branches and leaves can reduce nutrient consumption, let new leaves get more nutrition and grow better, so pruning is very necessary.

When will the fern be trimmed?

1. When the plant shape is messy

Due to the rapid growth rate of Dryopteris Dryopteris, its branches and leaves will be very luxuriant after a period of time, not only the branches and leaves will be too dense, but also the branches will be cluttered and crowded, resulting in a very messy appearance of the whole plant shape. it will also cause some of the leaves blocked inside to turn yellow due to lack of light, which needs pruning.

2. When changing the soil and removing the basin

In the culture method of Dryopteris Dryopteris, we have stressed that the pot soil should be changed every 1-2 years, and when the plant is removed from the flowerpot, some old fibrous roots in the roots need to be cut off, and this is also a rare water for root pruning in a year. Flower friends must not miss it.

3. Before resuming growth in spring

When Dryopteris is dormant over the winter, there will inevitably be some yellow leaves, dead branches, and so on. If they are left unchecked, they will affect their appearance, and it will be difficult to restore their green, so they also need to be pruned at this time. Cutting them will make them grow more vigorously when the spring growing season comes.

Pruning methods of Dryopteris Dryopteris

1. Use sharp scissors to cut off the thinner and old branches in the branches crossed together on the plant, so that the overall plant shape is maintained well, and the distribution of branches and leaves is more even. be careful not to cut off all the branches that are staggered together, otherwise it will look abrupt and ugly.

2. Stereotype. How do you trim the fern in the spring? In addition to cutting off withered and yellow branches and leaves, you can also use thin threads, sticks, brackets, etc., to let the plants grow in the desired direction, so that you can grow the shape you want, but you should pay attention to avoid breaking the branches when shaping.

IV. Matters needing attention in pruning

After pruning, the trimmed fern should not be placed in the sun, but should be maintained in a cooler place, waiting for the cut to dry, and then properly watered. At the same time, the pruned branches and leaves should be cleaned up to avoid falling into the flowerpot and mixing with the soil.

The culture methods and matters needing attention of Dryopteris Dryopteris, to teach you how to raise Dryopteris.

Among ferns, Dryopteris is one of the most popular cultivated species. Beautiful stems and leaves, beautiful shape, small plant type, very suitable for small pot cultivation and embellished with mountain and stone bonsai. Because the black petiole is slender and shiny, very similar to human hair, and its texture is very soft, like a girl's soft hair, it is also known as "girl's hair".

(1) morphological characteristics: perennial evergreen herbs, plant height 15cm-40cm. Rhizome transverse, densely brown lanceolate scales. Petiole slender, chestnut black, thin and hard, about 5-23 cm long, shaped like wire. Leaves sparse, ovate-triangular to oblong-ovate, 2-3-pinnatifid, pinnae suborbicular or fan-shaped, dark green, with obtuse rough notches. The sporangia are round and born on the back of the leaves.

(2) habits: originally wild on the wet rocks of the stream valley, like warm, humid and semi-shady environment, not cold-resistant, avoid direct sunlight. Like loose, fertile and calcareous sandy loam.

(3) cultivation and management: when potted, the pot can choose light glazed pots and tile pots; the basin soil must have good water permeability and ventilation, generally using peat soil or rotten leaf soil rich in humus, and then add about 1 to 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, and the rhizome planting depth is 1.5 to 2.5 cm.

Dryopteris likes shade and is afraid of light, so it can not grow smoothly under strong light. Potted plants should be cultured in half-day shade or indirect light in the shed, and avoid sun exposure in summer. The growing season should be fully watered. Usually can be watered once a day, summer can be watered twice a day, and maintain a high air humidity; summer high temperature season should also spray water to the leaves 2 or 3 times a day to keep the leaves green, and the basin can be soaked in water once a week. After the end of autumn, the watering times should be gradually reduced to keep the basin soil moist and enhance its cold resistance. When the water is insufficient, the leaves are easy to turn yellow. However, if the soil moisture is too saturated, or if the root is too dry, it will wilt or even die. The amount of fertilizer required is not much, liquid fertilizer can be applied once in 15-30 days during the growing period, and nitrogen fertilizer can be applied at the seedling stage. Do not stain the leaves when applying fertilizer, otherwise the leaves will be withered and yellow and the ornamental value will be reduced.

Dryopteris przewalskii has strong adaptability and fast growth. Overdense leaf clusters will lead to weak growth and yellowing leaves, so it should be propagated or changed in time. Dryopteris likes calcium fertilizer. When changing the basin, you can add a small amount of lime and broken eggshell to the basin to add some calcium fertilizer. Too dense foliage is not conducive to the germination of new leaves, which can be properly pruned in autumn to remove some old leaves and yellow leaves in order to keep the plant fresh and beautiful. The suitable temperature for growth is 18-25 ℃, and the overwintering temperature should not be lower than 10 ℃.

(4) Reproduction: commonly used ramet or spore reproduction

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, do not need to cover 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 ℃ and 25 met. the spores can germinate into prothalli for about one 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.

Matters needing attention in Dryopteris culture

Disease and pest control: there is mainly the harm of leaf blight. Bordeaux solution was sprayed for 1 and 2 times at the initial stage of the disease. Insect pests include scale insects, which can be sprayed with 1500 times of 50% malathion or 2.5% 3000 times of deltamethrin.

Brown scorched edge of leaf: Dryopteris leaves are most prone to brown scorched edge, which is a common problem in cultivation. Dryopteris is originally born in wet wall cracks or stone surfaces, and likes to be wet most. Due to the strong light in summer, Dryopteris can not grow normally if it is not placed in a shady environment. Direct sunlight will make the water of the leaves dry quickly, and before the root absorbs the water, some of the cells of the leaves have dried and dehydrated, and the green will gradually fade, so the focal edge will appear. Rescue measures:

① must be cultured in semi-shade immediately.

② cuts off the charred leaves and sprays water on the leaves and the surrounding ground in time.

③ should be carefully maintained to avoid being stimulated by strong light as far as possible.

The leaves blackened: the leaves of Dryopteris tend to blacken due to improper maintenance. The causes and prevention measures are as follows:

① has a low temperature 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 ℃.

② is too shady to see the sun for a long time. The iron fern is afraid of summer heat and cannot be exposed to the sun, but it cannot be completely shaded. It is best to put it in an outdoor shade shed and under big trees in summer, or move outside at night and back indoors during the day. You should see the light fully in winter.

The summer climate of ③ is muggy and poorly ventilated. The air humidity should be increased and ventilation should be strengthened.

④ fertilizer and water problems. Dryopteris prefers sandy loam rich in humus and needs plenty of fertility. Charcoal powder and brick shavings can be added to the culture soil to improve the aeration and permeability of the basin soil.

Dryopteris can absorb about 20 micrograms of formaldehyde per hour, so some people compare it to the most effective biological "purifier". It has a powerful role in air purification and plays an important role in improving the household environment.
