What is Climbing Fern?
Climbing Fern (Lygodium venustum) is a medium-care plant from the Schizaeaceae family. Lygodium venustum, known as the climbing fern, is a climbing pteridophyte native to Central and South America, especially abundant in dry forests and disturbed areas from Mexico to Paraguay. Its delicate fronds wind around supports with natural elegance, forming curtains of bright green foliage. It...
Climbing Fern grows up to 3.0m, spread of 100cm, watering every 3 days, 15°C – 30°C, 60–80% humidity. It is suitable for indoor environments and safe for pets.
Unlike many popular species, Climbing Fern is safe to keep around pets. Without adequate drainage, root rot can develop within 7 days.
How to Care for Climbing Fern?
TLDR: Climbing Fern needs Bright indirect, watering every 3 days, and temperatures between 15-30°C with 60-80% humidity.
How Often Should You Water Climbing Fern?
Water every 2-3 days to keep the soil slightly moist, but never waterlogged. In dry climates, check the substrate daily. Reduce frequency in winter. Use room temperature water to avoid thermal shock to the roots.
How Much Light Does Climbing Fern Need?
Prefers bright, indirect light with at least 6 hours of daily exposure. It can tolerate some mild direct morning sun, but avoid exposure to intense afternoon sun, which can burn the fronds. Indoors, position near an east- or north-facing window.
What Is the Best Soil for Climbing Fern?
Use a light, well-drained substrate, preferably a mixture of peat, perlite, and garden soil in equal parts. The ideal pH is between 5.5 and 6.5 (slightly acidic). Ensure the pot has adequate drainage holes to prevent root rot.
What Pot Should You Use for Climbing Fern?
Pots with generous drainage holes are essential. Opt for clay or terracotta pots that allow the substrate to breathe. As a climbing plant, combine with stakes, trellises, or vertical supports so the fronds can develop properly.

What Is Climbing Fern and Where Does It Come From?
Lygodium venustum, known as the climbing fern, is a climbing pteridophyte native to Central and South America, especially abundant in dry forests and disturbed areas from Mexico to Paraguay. Its delicate fronds wind around supports with natural elegance, forming curtains of bright green foliage. It is valued both as an ornamental plant and for its traditional medicinal use—prepared roots were used as an antivenom in indigenous communities in Nicaragua.
How to Propagate Climbing Fern?
Rhizome division
- 1 In early spring, carefully remove the plant from the pot
- 2 Identify the rhizomes and separate them manually or with a sterilized knife
- 3 Replant each division in an individual pot with fresh, well-drained substrate
- 4 Water lightly and keep in a place with indirect light until established
- 5 Avoid fertilization for the first 4 weeks after division
Spores
- 1 Collect mature fronds with dark spores
- 2 Spread the spores over moist, sterilized substrate in a covered tray
- 3 Maintain high humidity (80%) and a temperature of 22-25°C
- 4 Wait for germination in 4-8 weeks
- 5 Transplant the seedlings when they reach 3-5 cm in height

What Diseases Commonly Affect Climbing Fern?
TLDR: Climbing Fern is susceptible to 6 known diseases. Monitor regularly for early detection.
Root Rot
Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.
Powdery Mildew
Powdery mildew is a common fungal disease caused by various fungi species including Erysiphe, Podosphaera, Oïdium, and Leveillula. It affects over 10,000 plant species worldwide. The disease thrives in warm, dry climates with high humidity and appears as a distinctive white powdery coating on plant surfaces.
Spider Mites
Spider mites are tiny arachnids (less than 1/20 inch long) related to spiders and ticks that feed on plant sap. They thrive in hot, dry conditions and can cause significant damage to ornamental and vegetable plants. During severe infestations, crop losses can reach 14% or higher as these pests disrupt vital plant processes including photosynthesis, carbon dioxide absorption, and transpiration.
Scale Insects
Scale insects are small sap-sucking pests that appear as brown, shell-like bumps on plant stems and leaves. There are over 25 species, divided into armored (hard) and unarmored (soft) scales. They feed by piercing plant tissue and extracting sap, which weakens the plant and can lead to yellowing, stunted growth, and even death if left untreated. They also excrete honeydew, which attracts ants and promotes sooty mold growth.
