Warm summer days are wonderful for us, but for ferns, high temperatures can be quite a challenge. These lush, green plants are naturally accustomed to moist, sheltered spots in forests or tropical regions. When the thermometer rises, their roots dry out faster, and their fronds can burn. Fortunately, with the right care, you can keep both your outdoor ferns and indoor ferns healthy and beautiful. Why ferns struggle in the heat Ferns love consistent moisture, both in the soil and in the air. However, during warm and dry periods, three things happen that can cause stress: The sun evaporates moisture from the soil more quickly, causing the roots to dry out. Strong sunlight can damage fronds, leaving yellow or brown spots. Dry air (outdoors from heat, indoors from air conditioning) causes the fronds to dry out, making them turn brown and curl more quickly. By keeping these factors in mind, you can prevent most problems. Outdoor ferns in summer Outdoor ferns, such as Dryopteris , Athyrium , or tree ferns ( Cyathea  and Dicksonia ), can handle a warm summer day quite well. However, when temperatures rise above 25°C (77°F), they need some extra attention. 1. Provide shade Ferns naturally grow beneath the canopy of trees, where they receive filtered light. Make sure they are placed in a spot with morning sun or dappled daylight, but protected from the intense midday sun. Is your fern in a border that’s too sunny? Consider using a shade cloth during the hottest days. 2. Smart watering In warm weather, it’s better to water twice a day in smaller amounts (early in the morning and late in the evening). Keep the soil consistently moist , but avoid letting the roots sit in standing water – this can cause root rot. A drip irrigation system in the garden can be ideal for providing a steady, gentle supply of moisture. 3. Protect the soil with mulch A layer of bark, compost, or leaves around the base of the fern helps retain moisture and protects the roots from extreme heat. 4. Protect the fronds For some varieties, such as tree ferns, you can gently mist the fronds on hot days. Do this preferably in the early morning so the foliage has time to dry before the sun is directly overhead. Indoor ferns in warm temperatures Indoors, temperatures can rise quickly due to sunlight and heat coming through windows. Indoor ferns, such as Nephrolepis  (Boston fern), Asplenium  (bird’s nest fern), or Adiantum  (maidenhair fern), enjoy warmth but thrive best in high humidity. 1. Shelter from direct sunlight Direct sunlight can scorch the leaves. Place your fern about a metre away from the window, or use a sheer curtain to filter the light. 2. Increase humidity Place a shallow dish of water nearby or use a humidifier . Group plants together : as they release moisture, they naturally raise the humidity in the surrounding air. Lightly mist the foliage from time to time, but avoid the centre of the plant to prevent mould growth. 3. Check the potting soil more often Warm indoor air causes the soil to dry out more quickly. Insert your finger 2–3 cm into the soil: if it feels dry, it’s time to water. 4. Watch out for air conditioning and fans Do not place your fern directly in the airflow. This will dry out the fronds and can cause brown edges. Rainwater: the bonus for healthy ferns Ferns prefer soft water. Tap water often contains lime (calcium), which can cause leaf damage or discoloration over time. Rainwater is perfect: it’s softer, natural, and usually just the right temperature. Conclusion With a little extra care during hot days, your ferns will stay beautifully green and healthy. Keep their natural preferences in mind: filtered light, consistent moisture, and protection from extreme heat. This way, you can create a little tropical forest feeling in your garden or living room even in the middle of summer.

The Cyathea medullaris  is a striking tree fern known for its dark trunk and large, elegant fronds. In this blog, you'll learn more about its origin, appearance, and how to care for it properly. Where does Cyathea medullaris come from? This tree fern is native to New Zealand  and several Pacific islands, including Fiji and Samoa . In New Zealand, it's commonly known as mamaku , a name from the Māori language. It grows in moist forests with a mild, humid climate. In the wild, these plants can grow very large — up to 15 to 20 meters  tall. What does it look like? Cyathea medullaris has a straight, dark trunk, often almost black in color. That’s why it's also known in English as the black tree fern . Its fronds are bright green and can grow several meters long. They spread out gracefully from the top of the trunk, giving the plant a lush, almost tropical appearance. Like many ferns, young fronds slowly unroll from the center of the plant. Care tips Cyathea medullaris does have some specific needs in order to grow well. Here are a few key tips: Water : Keep the soil consistently moist, but not soggy. Never let the roots dry out, especially in summer. It’s better to water more frequently in smaller amounts than to soak it all at once. Humidity : This fern loves high humidity. Indoors, mist it regularly or use a humidifier Light : Place it in a spot with bright, indirect light. Outdoors, it prefers partial shade. Temperature : This fern is semi-hardy . Protect it from frost, especially when it's still young. An unheated greenhouse or sheltered outdoor spot is ideal. Soil : Use rich, well-draining potting soil. Adding bark or perlite can help improve drainage and aeration. Did you know... The trunk isn’t a real tree trunk? What looks like a trunk is actually a mass of old leaf bases and roots. It’s not made of wood like a regular tree. Young fronds curl into a ‘koru’? This spiral shape is called a koru  in Māori. It symbolizes new life, growth, and harmony — and is a common design in New Zealand art and tattoos. It’s a prehistoric species? Tree ferns like the Cyathea medullaris have existed since the time of the dinosaurs, making them true living fossils . Now available in size S Excited to add one to your collection?

When is the Best Time to Plant Ferns in Your Garden? Ferns are beautiful, atmospheric plants that give your garden a lush and natural look. But when is the best time to plant them? And what should you consider to ensure they grow well? In this blog, we provide the best tips for planting and caring for ferns in your garden. The Best Time to Plant Ferns The ideal time to plant ferns in the garden is early spring or autumn. During these periods, the soil is still moist and not too warm, allowing for good root development before summer heat or winter cold sets in. Spring (March - May):  Once the risk of severe frost has passed, ferns can be planted. They will have enough time to establish their roots before summer begins. Autumn (September - November):  The soil is still warm from summer, and there is often more rainfall, which helps the plants establish. Make sure not to plant them too late, so they have time to root before winter. Tips for Planting Ferns Want to give your ferns the best start? Keep these essential tips in mind: Choose the Right Location Most ferns thrive in shade or partial shade with moist, well-draining soil. Plant them under trees, along fences, or in a woodland border. Prepare the Soil Well Ferns grow best in humus-rich, moist soil. Add compost or leaf mold to improve soil structure and retain moisture. Keep the Soil Moist Especially in the first weeks after planting, it is crucial to keep the soil moist. Water regularly, particularly during dry periods. Check Winter Hardiness Some ferns are evergreen and tolerate cold well, such as the male fern ( Dryopteris filix-mas ). Other species, like the tree fern ( Dicksonia antarctica ), need extra winter protection. Cover them with a layer of leaves or fleece. Combine with Other Shade Plants Ferns pair beautifully with hostas, hellebores, and shade-loving ground covers like creeping bugle ( Ajuga reptans ). This creates a lush, natural-looking garden. Conclusion Want to plant ferns in your garden? Choose spring or autumn, ensure moist and humus-rich soil, and give them a sheltered spot in (partial) shade. With these tips, you can enjoy a thriving fern garden! Good luck planting your ferns!

Have You Ever Wondered How Ferns Are Grown? In our greenhouse, we have developed a meticulous process to grow these stunning plants from tiny spores into fully developed ferns. Take a peek behind the scenes and discover how we make it happen! Seed trays with the first fern fronds It All Starts with the Seed Trays Growing ferns begins with the smallest building blocks of a fern: the spores. These are carefully sown in specially prepared seed trays. The trays are filled with a fine, airy soil mix, ideal for germination. The spores are evenly spread across the surface and left uncovered, as they need light to germinate. The trays are then covered with plastic sheeting to create a humid and warm environment. After a few weeks (or sometimes months), the first signs of life appear: tiny heart-shaped structures called prothallia, which form the foundation of the fern plants. Transplanting: Creating Space to Grow Once the prothallia have grown into small fern plants, it’s time for the next step: transplanting. This involves carefully moving the young plants to a new environment with more space. At this stage, each plant receives individual attention. We place them in specially designed trays, which can hold between 100 and 250 plants depending on their size. By giving the plants enough space, they can grow without competing for light and nutrients. Potting: Ready for the Big Stage As the ferns grow larger and stronger, they are ready for their own pots. We use pots of various sizes, ranging from 5 cm to 14 cm in diameter. The young ferns are gently transferred and firmly placed in the soil. An initial watering helps them settle into their new environment. These pots are placed in a controlled setting where the light conditions and humidity are perfectly adjusted to support their growth. Final Care Our care for the ferns doesn’t stop after potting. We closely monitor them to ensure they remain healthy and continue to grow optimally. Regular watering and adjustments, when needed, are essential. Through this process, our ferns grow into strong, beautiful plants, ready to begin a new life in your home or garden. With love and attention, we ensure every fern gets the best possible start. Bringing a touch of nature closer to you!

Ferns are beautiful plants, but they can sometimes suffer from various problems and diseases. In this blog post, we discuss the most common issues with ferns and how to recognize and effectively treat them. 1. Brown Leaf Edges and Tips The edges and tips of the leaves become brown and dry. Causes: Dry air: Ferns love a humid environment. Dry air, especially in winter, can lead to dehydration. Insufficient water: Ferns need regular watering but should not constantly stand in wet soil. Treatment: Increase humidity: Use a humidifier, place the fern on a tray with pebbles and water, or mist the leaves regularly.

By recognizing these common problems early and applying the right treatments, you can ensure your ferns stay healthy and continue to enjoy their green beauty.

As spring approaches, it's time to prepare your indoor ferns for the new growing season. These beautiful plants not only enhance your interior decor but also bring a peaceful and green atmosphere to any space. Here are some essential steps to optimally prepare your indoor ferns for spring: 1. Potting and Soil Quality First, check if your indoor ferns have enough space to grow. If the roots start growing out of the drainage holes or if the plant seems too large for its current pot, it's time to repot into a slightly larger container. Choose a pot with good drainage holes to allow excess water to drain away and use a quality potting mix that is light and well-draining. 2. Cleaning and Maintenance Thoroughly inspect your indoor ferns for any dead or damaged leaves and carefully remove them with scissors or pruning shears. Removing old foliage will stimulate the growth of new shoots and keep your plants healthy and vibrant. 3. Light and Temperature Place your indoor ferns in a location with bright, indirect light. While these plants naturally thrive in shaded environments, they still need some light to grow well. Avoid direct sunlight as it can scorch the leaves. Also, ensure that the room temperature is not too high or too low, ideally between 18-24°C. 4. Watering your indoor ferns in spring During the spring period, it's important to maintain a consistent but not excessive watering schedule. For many ferns, the potting mix should always remain lightly moist. However, be careful not to overwater as this can lead to root rot. 5. Feeding Give your indoor ferns a light dose of fertilizer in spring to stimulate growth. Choose a balanced, water-soluble fertilizer specially formulated for indoor plants. Follow the instructions on the packaging for the correct dosage and apply the fertilizer every few weeks during the growing season. With these simple yet effective tips, you can optimally prepare your indoor ferns for the upcoming growing season. By giving them the right care and attention, your indoor ferns will thrive and brighten up your home with their lush greenery throughout the spring and summer.

Outdoor ferns are beautiful plants that can embellish your garden or patio with their lush greenery, even in the colder months. But to ensure that your outdoor ferns survive the winter and come back to life in the spring, it's important to take some specific care measures. In this blog we take a closer look at the care and protection of outdoor ferns in winter. 1. Choose the right fern species Not all fern species are equally hardy. Make sure you select fern varieties that are suitable for the climate in your region. For example, in temperate climates, the autumn fern (Dryopteris) often winter hardy. 2. Isolate with mulch In the fall, before frost sets in, you can apply a thick layer of mulch around the base of your outdoor ferns. This helps protect the roots from severe frost and keeps the soil at an even temperature. Use organic material such as leaves, straw or compost for good insulation. 3. Limit watering During the winter, outdoor ferns need less water because they are dormant. Excessive watering can lead to root rot. Check the soil occasionally and only water if it feels very dry. Please note that water requirements depend on local weather conditions. 4. Protect from strong winds Strong winter winds can cause drying and damage the fern's foliage. You can install a temporary wind barrier, such as a fence or mesh, to protect your outdoor ferns. Make sure the barrier does not suffocate the plant and allows adequate air circulation. 5. Do not prune dead leaves Although it may be tempting to prune dead or yellow fronds from your outdoor ferns, it is best not to do so in winter. The dead leaves act as a natural protection for the plant, and pruning can weaken the fern. Wait until spring to carry out any pruning work. 6. Consider relocation In some cases it may be wise to move pots of outdoor ferns to a sheltered location such as a greenhouse or veranda during the winter. This provides extra protection against severe weather conditions. Make sure that the plant still gets enough light. Caring for outdoor ferns in winter requires some attention and care, but with the right measures, these beautiful plants can thrive even in cold climates. By selecting hardy fern varieties, insulation with mulch and protection from wind, you can enjoy green, lush outdoor ferns in your garden all year round.
