Anubias – An Overview
Anubias is a genus of aquatic, semi-aquatic, and semi-terrestrial plants belonging to the Araceae family. The plants are native to tropical African regions and grow in marshy habitats, near streams, and other wet areas. There are around 70 species of Anubias, comprising of submerged and emergent aquatic plants, terrestrial plants, and hybrids. Anubias plants are highly popular in the aquarium and water garden trade because of their attractive foliage, ease of care, and slow growth which makes them ideal for aquascaping.
How Tall Does Anubias Grow?
The maximum height a Anubias plant can reach depends on the species and its growing conditions, but as a general rule of thumb, Anubias plants typically reach a maximum height of about 18 inches (45 cm). Some species, such as Anubias barteri, can reach up to 24 inches (60 cm) in height, while others, such as Anubias nana, stay relatively small and reach only 4-6 inches (10-15 cm).
Factors That Affect Anubias Height
The height of Anubias plants is affected by several factors, including the species, light, fertilizer, water temperature and flow, and the substrate. The species of Anubias will affect the maximum height the plant can reach, with some species reaching a greater height than others. Light is also important for Anubias growth and plants grown in low light will reach a shorter height than those grown in higher light. Fertilizer, water temperature and flow, and the substrate can also affect Anubias growth, as can overcrowding and inadequate pruning.
Light Requirements for Growing Anubias
Anubias plants need bright light to grow, but they are not tolerant of direct sunlight and will be damaged if exposed to it. For best growth, Anubias should be grown in medium to high light, which can be provided by fluorescent or LED lights. As Anubias is a slow-growing plant, it can be grown with low to medium light intensity, but high light will promote better growth.
Fertilizer for Anubias
Anubias plants do not need much fertilizer, but they do benefit from a good quality liquid fertilizer applied every month or so. It is best to use a fertilizer specifically designed for aquatic plants, as these contain the right balance of nutrients to promote growth and flowering. If the water is well-supplied with nutrients, Anubias will benefit from a fertilizer supplement.
Water Temperature and Flow for Anubias
Anubias plants prefer a water temperature of between 72-79°F (22-26°C). The plants can tolerate temperatures outside of this range, but for best growth, it is best to keep the temperature within this range. Anubias plants also prefer a slow to moderate water flow, as this helps to keep the water oxygenated and prevent the leaves from becoming waterlogged.
Substrate for Anubias
Anubias plants can be grown in a variety of substrates, including gravel, sand, and clay. For best growth, it is best to use a nutrient-rich substrate that is well-draining, such as a mix of sand and gravel. Anubias can also be grown on bogwood or rocks, as long as the substrate is not too compacted.
Overcrowding and Pruning Anubias
To prevent overcrowding, Anubias plants should be planted at least 4-6 inches (10-15 cm) apart. It is also important to prune the plants regularly to keep them from becoming too tall and overgrown. Pruning should be done by snipping off the top leaves, as this will encourage lateral branching and help keep the plant compact.
Conclusion
Anubias plants are popular aquatic plants due to their attractive foliage and ease of care. The maximum height of Anubias plants depends on the species and growing conditions, but as a general rule, Anubias plants typically reach a maximum height of about 18 inches (45 cm). Factors such as light, fertilizer, water temperature and flow, and the substrate can affect Anubias growth, as can overcrowding and inadequate pruning.
