Dryopteris affinis, the scaly male fern or golden-scaled male fern, is a fern native to western and southern Europe and southwestern Asia. It is most abundant on moist soils in woodlands in areas with high humidity, such as the British Isles and western France. In the Mediterranean region and the Caucasus it is confined to high altitudes.
Scaly male fern tends to be disease-resistant and is affected by relatively few insect pests. Its care is considered challenging because it needs consistently moist conditions and frequent watering. At the same time, the roots can rot if the plant is overwatered or the surroundings are poorly ventilated. It is best suited to people with some growing experience, since most can keep it alive for a period of time. Nevertheless, the fern may struggle to thrive, with leaves that dry out and become less healthy as time passes.
How to keep Dryopteris Affinis.
Light
Scaly male fern generally prospers with moderate sunlight and readily adjusts to both full shade and very bright sun. Excessive strong sunlight can cause its foliage to bleach, while inadequate light leads to reduced growth rates. This adaptability mirrors the woodland environments where it naturally occurs.
Water
The scaly male fern is well-suited to the moist understorey of temperate forests. It thrives in consistently damp soil, so you should water it twice a week. Although it has moderate drought tolerance, this evergreen plant needs hydration all year long. This is especially important in the winter when indoor heating can reduce humidity.
Temperature
Scaly male fern does best in forest thickets. It is very sensitive to temperature and humidity, and high heat, dry conditions, or strong sunlight can all stress the plant. In summer it needs adequate shading and a humid environment. Generally it does not need special care in winter, but an extended winter drought can still be lethal.
Pruning
The scaly male fern is known for its sturdy, arching fronds and distinct textured scales. To maintain its health and appearance, prune the fern in early spring by removing old or damaged fronds. This practice encourages healthy growth and helps maintain a pleasing shape. Proper pruning also improves air circulation, which reduces the risk of disease and enhances both the plant's appearance and longevity.

Reader questions.
What should I do if I give my Scaly male fern too much or too little water?
The Scaly male fern can be overwatered if it is left in a pool of water or if the planter does not have drainage holes. This can cause the roots to be unable to take up nutrients and moisture and can lead to the development of fungal or bacterial diseases. If the fern is overwatered, the leaves may become wilted and yellow and the stems may droop or feel soft and mushy. However, it is important to check for other causes of these symptoms, as it can be difficult to give the plant too much water. On the other hand, the Scaly male fern can also be underwatered if not monitored closely. In dry conditions, the appearance of the plant can change quickly from lush and green to brown and crispy. In extreme cases, the plant may dry up completely, but if some roots are still healthy, it is possible to save the plant. To do so, cut off all dry and dead stems, water thoroughly, and return the plant to its usual location. With proper care, the fern can recover and start to grow new fronds, although it may take several months to regain its previous size.
Why is it important to fertilize my Scaly male fern?
Fertilizing Scaly male fern is necessary for a few reasons. Firstly, it helps provide the necessary nutrients for healthy new growth. Secondly, it supports the overall health of the plant, including the old growth, and aids in the prevention of diseases and pests.
What are the sunlight requirements for Scaly male fern?
The Scaly male fern requires moderate sunlight exposure, thriving in both fully shaded and intensely sunlit environments. It is adaptable, reflecting its native woodland habitats, but excessive sunlight can lead to foliage bleaching, and insufficient light can slow down its growth. The plant needs about 3-6 hours of sunlight. In full shade or full sun conditions, it receives less than 3 hours of sunlight daily. It's important to watch the sunlight's movement through your garden to choose spots that provide a perfect balance of light and shade, ensuring the plant's well-being.
What is the botanic name of the Scaly male fern?
The botanic name of the Scaly male fern is Dryopteris affinis. This fern is recognized by its distinctive name and lacks additional common names in the provided information.
How do I make sure my Scaly male fern gets enough water?
To properly care for your Scaly male fern, it needs consistently moist soil to replicate its natural habitat. This may require watering every one or two days, as it is crucial to prevent the plant from drying out. When you notice the top layer of soil becoming slightly dry, it indicates the need for watering. Ensure thorough watering by completely saturating the soil until water drains out from the pot's bottom. Afterward, remove any excess water to avoid sitting in a puddle. Following this method will help maintain the soil's moisture levels and prevent it from becoming too dry.
When should I fertilize my Scaly male fern?
The feeding schedule of the Scaly male fern depends on where it is growing. This plant doesn't require a lot of food, but it does need some extra nutrients. For outdoor plants, you only need to fertilize them once in the spring. However, indoor specimens should be fed monthly, starting in the spring and continuing through the summer.
Can I use artificial lighting for Scaly male fern?
Yes, artificial lighting is a viable solution for Scaly male fern when natural sunlight is insufficient, especially in less sunny spaces or during winter. Optimal growth is achieved with adequate lighting. LED lights are recommended due to their capability to provide specific wavelengths needed by plants. The required wattage varies depending on the plant's sunlight needs: 30-50W/sq ft for full sun plants, 20-30W/sq ft for partial sun, and 10-20W/sq ft for full shade. The artificial light source should be placed 12-36 inches above the plant and left on for 8-12 hours per day to mimic natural daylight hours.
What things should I think about when I water my Scaly male fern?
The watering needs of your Scaly male fern depend on the humidity levels in the air. Higher humidity means less frequent watering. Avoid placing the plant near heating or cooling vents as it can cause it to dry out quickly. Find a location that is protected from drafts.
