- Maintain high humidity for the new plants.
- Avoid dividing very young or unhealthy plants.
- 1 Remove the plant from the pot
Carefully remove the fern from the pot, shaking off excess soil from the roots.
- 2 Divide the rhizome
Identify sections of the rhizome with several healthy fronds and roots. Use a sharp, sterilized knife to cut the rhizome into sections.
- 3 Plant the divisions
Plant each section in a new pot with fresh, well-draining substrate, ensuring the rhizome sits slightly above the soil line.
- 4 Water and care
Water thoroughly after planting and keep the new plants in a high-humidity area with indirect light until they become established.

What Diseases Commonly Affect Crocodile Fern?
TLDR: Crocodile Fern is susceptible to 5 known diseases. Monitor regularly for early detection.
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.
Mealybugs
Mealybugs are small, soft-bodied insects covered with a white, waxy, cottony material. They are common pests of houseplants and outdoor plants in mild climates. These sap-sucking insects feed on plant tissue, causing damage, stunted growth, and can lead to plant death if left untreated. They produce sticky honeydew which attracts sooty mold.
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.
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.
