What if the leaves of Dryopteris fern wither?

Clematis, also known as clematis, etc., is a perennial herb of the genus Dryopteris of the family Pteridaceae, with strong adaptability and easy cultivation. It is suitable for perennial potted plants indoors. 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 shady room. At the same time, they are also good materials for cutting leaves and dried flowers. Let's take a look at how the leaves of Dryopteris withered.

Soil discomfort

[reason] Dryopteris needs to change the basin every spring, like the loose, permeable and fertile calcareous sandy loam, pay attention to the choice of soil, if the soil is not suitable, it is easy to cause the leaves of Dryopteris to yellowing and falling.

[methods] Dryopteris likes calcium fertilizer, and a small amount of lime and broken eggshell can be added to the basin to add some calcium fertilizer.

Pruning discomfort

[reason] when withered leaves are found in the maintenance process, Dryopteris should be cut off in time to keep the plant fresh and beautiful and conducive to the germination of new leaves, otherwise too messy and crowded branches and leaves will lead to weak growth and yellowing of leaves.

[methods] when the clump of fern leaves is too dense, the old leaves can be pruned properly every autumn.

Insufficient watering

[reason] during the growth of Dryopteris, it is necessary to fully water and maintain high air humidity to keep the leaves dark green. If the water supply is insufficient or the air is dry, the leaves will turn yellow or curl scorched.

[methods] the branches and leaves of Dryopteris should be sprayed 2 or 3 times a day during the peak growing season.

The light is too strong

[reason] Dryopteris is a shade plant, such as strong light, it is easy to cause scorched leaf margin and yellow leaves.

[methods] the cultivation of Dryopteris should pay attention to shade outside, but it also needs to provide sufficient sunlight, and it is best to keep the flowerpot on the east or north windowsill of the room indoors.

Improper fertilization

[reason] improper watering and fertilization of Dryopteris will stain the leaves, resulting in the withering and yellowing of the leaves and affecting the ornamental effect.

[methods] the amount of fertilizer needed for Dryopteris is not much. It is generally possible to apply thin pancake fertilizer and water every 2 to 3 weeks, and the effect is better if a small amount of calcareous fertilizer can be added.

Too much watering

[reason] Dryopteris likes the environment with high humidity, but if it is watered too much, it will also cause stagnant water, thus causing the leaves of Dryopteris to dry up.

[methods] Dryopteris should be maintained in accordance with the principle of less watering and more spraying. Dry places in the north can consider putting a plate under the basin with water to achieve the purpose of increasing air humidity.

Matters needing attention

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: clematis like a humid environment, and should be fully watered during the peak growing season. Besides keeping the basin soil moist, we should also pay attention to high air humidity.

3. Sunlight: Dryopteris likes bright scattered light, afraid of direct sunlight, the light is too strong, the leaves are yellow or even die, and the leaves can be properly shaded in summer. Direct light for a long time will cause most of the leaves to wither and yellow.

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. It should be cultured in greenhouse in winter.

5. Fertilization: rarefied liquid fertilizer is applied to Dryopteris Dryopteris 2 or 3 times a month, do not stain the leaf surface, so as not to cause rotten leaves, basin soil should add appropriate amount of lime and broken eggshell, reduce watering and stop fertilization in winter.

6. Insect pests: leaf blight often occurs in Dryopteris. 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 there is a scale insect damage, 40% omethoate 1000 times solution can be used for control.

7. 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 cut them off.
