How Do You Care For Dryopteris Wallichiana?

When established, Dryopteris Wallichiana (wood ferns) are low-maintenance, slow-growing plants that require little effort. Provide just enough water to prevent the soil from becoming completely dry. Many species of wood fern are tolerant of damp circumstances and can even be seen growing near streams and ponds.

Dryopteris Wallichiana (Wood ferns) will not grow in the shade, however, they will tolerate low-light conditions. They do well in areas that receive dappled sun or light shade.

They prefer moist, humusy soils but will adapt to most garden soils if properly watered and fertilized. The following are the factors to consider when caring for Dryopteris Wallichiana;


Dryopteris Wallichiana (Wood Ferns) can tolerate dappled sunlight but prefer partial shade. Position in an area where they receive indirect light but are shielded from hot afternoon sun. Dryopteris Wallichiana (Wood ferns) will still remain healthy and attractive with their fronds growing in just 6-hour intervals per day.


The soil that Dryopteris Wallichiana (Wood ferns) are planted in should be friable (loosely packed but not soggy). The plants should be watered thoroughly and evenly on a regular basis to insure good root development. In addition, be sure to fertilize the soil regularly to improve overall health.


Although Dryopteris Wallichiana (Wood ferns) are not particular when it comes to watering, they do appreciate being kept moist. Watering every 3-4 weeks will insure proper soil moisture levels, as well as provide a space for the roots to form healthy new growth.

This plant will not tolerate standing water for extended periods of time. When watering, be sure that the soil is fully saturated and then allow the water to drain through the plant’s root system.


Dryopteris Wallichiana (Wood ferns) are not particularly particular about temperature. They tolerate a wide range of temperature variations. Although this plant prefers cooler weather, it will tolerate warmer temperatures to a point.

As the weather becomes hotter, the fronds will begin to brown and die back. This species is frost-tolerant and is able to survive temperatures as low as -30 degrees Celsius (-22 F).


Dryopteris Wallichiana (Wood ferns) prefer a moderate amount of humidity. They are not prone to mildew but will benefit from being misted or soaked periodically throughout the year. Dryopteris Wallichiana (Wood ferns) are tolerant of varying humidity levels, but will not tolerate damp conditions for prolonged periods of time.


Dryopteris Wallichiana (Wood Ferns) should be fertilized at the beginning of each season to promote strong growth. It is ideal to fertilize in early spring just as new fronds are emerging from the ground. Applying a balanced fertilizer will help to promote vigorous growth and compact, attractive fronds that remain upright and dark green.


Dryopteris Wallichiana (Wood ferns) are propagated from sowing spores and division. The seeds are sown in pots or trays of 1:1 peat moss and sand. The surface should be lightly sprinkled with sand to cover the seeds and then moistened.

Do not place the pot in an overly hot location as this plant is prone to rot. New fronds should emerge from the soil within two weeks. Dryopteris Wallichiana (Wood ferns) can be propagated by division after they have formed a mat of foliage approximately 16″-24″ across.


Dryopteris Wallichiana (Wood ferns) should be repotted every 2 years. The plants should be placed in a small, pot that is just big enough for their roots to grow.

If the root system is allowed to become too large, only part of the plant’s root system will remain healthy and the plant may begin to develop a lot of unhealthy fronds and dry out. Repotting should be performed in late spring or early summer when the new leaves are still tight and compact.


The graceful, wavy fronds of Dryopteris Wallichiana (Wood ferns) should be pruned regularly to shape. To do so, remove any dead or damaged leaves and check to see if your fern is growing up too high.

If it is getting too tall, remove the uppermost top frond by cutting it off at the base where its stem connects with the frond. This will help to keep it in proportion with other plants as well as improve its color and fertility in the soil.

Are Dryopteris Wallichiana Evergreen?

Dryopteris Wallichiana is evergreen. As long as you provide it with all of the sunlight, water and fertilizer that it needs in order to grow, it will stay green all year long. It will be dormant during the winter months which is a good thing because that is when it produces its seeds.

Dryopteris Wallichiana (Wood ferns) will also remain green in the shade because of the high proportion of microscopic chlorophyll in their fronds. The thick layer of this substance absorbs sunlight.

When it detects light, this substance pushes water up its stalks to be released through a number of tiny pores as little droplets which enable Dryopteris Wallichiana (Wood ferns) to survive in places that other plants cannot tolerate. Its fronds remain green during cold weather, but their posture changes from erect to prostrate during winter.

Dryopteris Wallichiana is not a cold hardy plant and will only survive if it is protected from the cold by row cover or a covered structure. If the temperature dips below -15°F, the Dryopteris Wallichiana will begin to rot, leaving behind a mess of dead leaves and stems.

The soil beneath this plant will also freeze in low temperatures and become compacted by all of the snow that you should put under it every year.

Is Dryopteris Wallichiana Hardy?
