How to raise potted Dryopteris?

Dryopteris, also known as clematis, etc., is a perennial herb of the genus Dryopteris of the family Pteridaceae, with strong adaptability and easy cultivation, suitable for indoor perennial potted plants, and small potted plants can be placed on the desk or coffee table. Larger potted plants can be used to decorate the windowsill, aisle or living room of the shaded room, and they are also good materials for cutting leaves and dried flowers. Let's take a look at how to raise potted ferns.

Growth habits of Dryopteris Dryopteris

Dryopteris prefers loose, permeable and fertile calcareous sandy loam, and the cultivated soil can be mixed with loam, rotten leaf soil and river sand. The suitable temperature for growth is 21: 25 ℃ in daytime and 12: 15 ℃ at night. The leaves can keep fresh green when the temperature is above 5 ℃, but freezing injury will occur when the temperature is lower than 5 ℃. Like bright scattered light, 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.

Propagation methods of Dryopteris Dryopteris

1. Split-plant reproduction: Dryopteris can be propagated indoors for four seasons, but usually in early spring, the mother plant is taken out of the basin, its rhizome is cut off, and each piece is planted in a small basin with part of the rhizome and leaves, and then planted in a small basin. The new plant can be obtained by covering the rhizome with mixed soil and irrigating and culturing in a wet environment.

2. Spore reproduction: Dryopteris can also be propagated by spores. Peat and fine sand as substrates are disinfected at high temperature in the oven to kill germs and weed seeds. Then, the sterilized soil is put into a shallow sowing basin, the leaves with mature spores are cut, and the spores are concentrated and evenly sowed in the shallow sowing basin. There is no need to cover the soil, covered with glass sheets, soaked in water from the bottom of the basin, to keep the basin soil moist. The spores can germinate into prothalli in about one month under the semi-overcast environment of 20-25 ℃, and can be planted when the pot is full.

How to raise potted Dryopteris?

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

2. Watering: the fern 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. 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 cold-tolerant, 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 to Dryopteris Dryopteris 2 or 3 times a month, and do not stain the leaves so as not to cause rotten leaves. Due to the calcium-loving habits of Dryopteris, appropriate amount of lime and broken eggshell should be added to the basin soil, and the effect of calcium 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: after the beginning of autumn, the fern enters a slow growth stage with the drop of temperature, and the old leaves will gradually turn yellow, so cut them off.
