Ferns, a lineage of vascular plants, have graced the Earth for hundreds of millions of years, boasting a rich history dating back to the prehistoric era. They flourish worldwide, thriving in moist conditions ranging from rainforests to woodlands and even deserts. Native to diverse regions such as tropical jungles, temperate forests, and subtropical climates, ferns exhibit remarkable adaptability to various environments.

In addition to their natural habitats, ferns have found their way into human spaces, where they are cherished for their ornamental beauty and air-purifying qualities. With their diverse leaf shapes and textures, ferns offer endless possibilities for styling and incorporating them into indoor and outdoor landscapes. From cascading varieties perfect for hanging baskets to compact species ideal for tabletop arrangements, ferns lend themselves well to a range of planting styles.

For those with limited space, ferns can thrive in vertical gardens, adding lush greenery to walls and fences. Terrarium enthusiasts can create miniature fern ecosystems, complete with mosses and small decorative accents. Ferns also excel as mounted specimens, showcasing their trailing fronds against a backdrop of bark or driftwood.

Whether adorning a shaded patio, brightening a dim corner indoors, or enlivening a woodland garden, ferns bring a timeless elegance and sense of tranquility to any setting. With their ancient lineage and enduring appeal, ferns continue to captivate plant lovers around the world, inviting them to explore the beauty of nature's green wonders.

Toxicity: While ferns are generally non-toxic to humans and animals, some species may cause mild irritation if ingested. It's advisable to keep ferns out of reach of curious pets and children.

Ferns Common Symptoms

• Yellow Leaves: The yellowing of fern leaves typically indicates overwatering or exposure to direct sunlight.  Ensure proper drainage by using a well-draining potting mix, that still holds some moisture, and pots with drainage holes. Adjust the fern's location to a spot with indirect sunlight and avoid overwatering. Allow the top inch of soil to dry out before watering again.
• Leaf Drop: Excessive leaf drop can occur due to underwatering, low humidity, or sudden temperature fluctuations. Maintain consistent watering, ensuring the soil remains evenly moist. Increase humidity levels by misting the fern's leaves regularly or placing a humidity tray nearby. Avoid placing ferns near drafts or heaters to prevent temperature fluctuations.
• Fuzzy White Growth: Fuzzy white growth on fern foliage indicates a fungal infection, commonly known as powdery mildew, which thrives in humid conditions. Trim  back any infected leaves, and provide ventilation. If the infection is severe, treat with a fungicide such as Copper Soap.
• Crisping Foliage: Crisping or browning of fern foliage may result from insufficient humidity or exposure to dry air. Increase humidity levels around the fern by misting the leaves daily or placing a humidifier nearby. Grouping ferns together can also help create a microclimate with higher humidity. Ensure adequate airflow to prevent stagnant air around the plant.
• No Growth: Lack of growth in ferns can be attributed to inadequate light, nutrients, or root-bound conditions. Assess the fern's lighting conditions and provide sufficient indirect sunlight. Avoid making the common mistake that ferns do not need light. Feed the fern with a balanced liquid fertiliser at a diluted ratio during the growing season and ensure it is not root-bound by repotting it into a slightly larger container with fresh potting mix.
• Mushy Stems: Mushy or rotting stems indicate overwatering and poor drainage. Allow the soil to dry out slightly between waterings, and ensure the pot has proper drainage. Trim away any mushy or rotting stems with clean, sharp scissors to prevent the spread of disease. Improve ventilation around the plant to reduce humidity levels and prevent fungal growth.
• Wilting fronds can be caused by underwatering, root rot, or excessive heat. Check the soil moisture levels and water the fern thoroughly if the soil feels dry. Ensure proper drainage to prevent waterlogging and root rot. If exposed to excessive heat, relocate the fern to a cooler, shaded area. Trim away any wilted or damaged fronds to encourage new growth.
• Pests: Common pests that may affect ferns include spider mites, scale insects, and mealybugs. They are commonly spotted when fern leaves start to curl. Inspect the fern regularly for signs of pest infestation, such as webbing, sticky residue, or tiny insects. Treat affected plants with neem oil or organic pesticides, ensuring thorough coverage of both the tops and undersides of leaves. Isolate infested ferns to prevent the spread of pests to other plants. To identify pests, have a look at our: Pest Identification Blog.

Basic Fern Care Instructions

• Origin: Ferns originate from various regions worldwide, including tropical rainforests, temperate woodlands, and subtropical climates. Some varieties are even found in the desert, and go dormant during the no-rainfall period.

FUN FACT: Certain desert-adapted ferns, such as the Resurrection Fern (Pleopeltis polypodioides), are capable of going dormant during periods of drought or low rainfall. During dry spells, these ferns curl up and appear brown and withered, seeming almost dead. However, when moisture returns, they quickly revive, unfurling their fronds and resuming growth. This remarkable ability to enter dormancy and revive when conditions improve allows desert ferns to survive in harsh environments where water is scarce.

• Height: Ferns vary in height, with some species growing compactly while others can reach several metres in height.
• Light: Most ferns thrive in indirect or filtered sunlight. Avoid exposing them to direct sunlight, which can scorch their delicate foliage.
• Water: Keep the soil consistently moist but not waterlogged. Water thoroughly when the top inch of soil feels dry to the touch, and ensure adequate drainage to prevent root rot.
• Humidity: Ferns prefer high humidity levels, ideally between 50% to 80%. Increase humidity by misting the leaves, placing the plant on a tray filled with pebbles and water, or using a humidifier.
• Temperature: Maintain temperatures between 15°C to 24°C. Avoid exposing ferns to drafts or extreme temperature fluctuations.
• Soil: Use a well-draining potting mix rich in organic matter, such as peat moss or mixes formulated for ferns. A slightly acidic to neutral soil pH (around 5.5 to 7.0) is ideal for most fern species.
• Fertiliser: Feed ferns with a balanced liquid fertiliser diluted to half strength during the growing season (spring to early autumn). Avoid overfertilizing, as it can lead to salt buildup and damage the plant's roots.
• Pruning: Remove dead or yellowing fronds regularly to maintain the plant's appearance and promote healthy growth. Use clean, sharp scissors or pruning shears to make clean cuts at the base of the frond.
• Repotting: Repot ferns every 1 to 2 years to refresh the soil and provide room for root growth. Choose a pot slightly larger than the current one, and gently loosen the roots before placing the plant in its new container.
• Propagation: Ferns can be propagated through division or spores. Divide overcrowded clumps of ferns during the growing season, ensuring each division has healthy roots. Alternatively, collect spores from mature fronds and sow them in moist soil to propagate new plants.
