Anubias plants are a popular choice for aquatic environments like aquariums and paludariums, known for their hardiness and adaptability, making them suitable for all plant enthusiasts. Propagating Anubias allows owners to multiply their collection; this straightforward process involves creating new plants from an existing one.
Understanding Anubias for Propagation
Anubias plants possess a unique growth structure centered around their rhizome. The rhizome is a horizontal, thick stem from which both leaves and roots emerge. This structure is crucial for the plant’s health and successful propagation. A fundamental rule is to avoid burying the rhizome in the substrate, as this can lead to rot. While roots can be buried, the rhizome must remain exposed.
Step-by-Step Anubias Propagation
Propagating Anubias primarily involves dividing its rhizome. Select a healthy, mature parent plant with robust growth and multiple leaves. Sterilize sharp cutting tools, like scissors or a razor blade, to prevent pathogens and minimize stress on the plant.
Carefully identify suitable cutting points along the rhizome. Each new section should ideally have at least two to three leaves and some healthy roots. Make a clean cut through the rhizome, avoiding crushing the tissue. Alternatively, make small, shallow notches in a bare rhizome section to encourage new growth.
Once separated, secure the new Anubias pieces to hardscape elements like driftwood or rocks, as the rhizome should not be buried. Common attachment methods include aquarium-safe super glue gel, fishing line, or cotton thread. For glue, apply a small amount to the hardscape or rhizome (avoiding roots) and press the plant firmly until it adheres. Roots will eventually anchor the plant.
Post-Propagation Care
After propagation, newly divided Anubias benefit from stable environmental conditions. They prefer moderate to low light levels; excessive light can cause algae growth. Consistent water parameters (temperature, pH) reduce stress. Anubias absorb nutrients directly from the water column, so liquid fertilizers are beneficial, especially for new plants. Growth is slow, with new leaves appearing every few weeks as the plant establishes.
Troubleshooting Propagation Issues
One common problem is “melting” leaves or rhizome rot, often due to a buried rhizome, sudden water parameter shifts, or general stress. If observed, trim affected leaves and ensure the rhizome is exposed. Slow or absent growth might stem from insufficient light, lack of nutrients, or unstable water conditions. Adjusting lighting, ensuring proper nutrient levels, and maintaining stable water parameters can help stimulate growth. Algae growth, particularly green spot algae, often signals excessive light; reducing light or introducing algae-eating invertebrates can manage this.
