Understanding Anubias Plant Growth Stages:
A Comprehensive Guide

Updated: May 12, 2023

Anubias is a popular aquatic plant that is perfect for aquariums. It is easy to care for and can be grown in a variety of conditions. However, understanding the growth stages of Anubias plants is crucial for their successful cultivation. In this comprehensive guide, we will explore the different growth stages of Anubias plants, the factors that affect their growth, and how to care for them at each stage.

The Three Growth Stages of Anubias Plants

1. Emergent Stage

The emergent stage is the first stage of Anubias plant growth. At this stage, the plant has just been planted in the aquarium substrate, and its leaves are still above the water surface. During this stage, the plant will focus on establishing its roots in the substrate.

It is important to note that Anubias plants do not like to be planted too deeply into the substrate. The rhizome (the thick stem from which the leaves grow) should be planted just above the substrate surface. If planted too deeply, the rhizome may rot and cause the plant to die.

2. Vegetative Stage

The vegetative stage is the second stage of Anubias plant growth. At this stage, the plant has established its roots in the substrate and has started to grow new leaves. During this stage, the plant will focus on growing new leaves and increasing its foliage.

It is important to provide adequate lighting and nutrients during this stage to ensure healthy leaf growth. Anubias plants prefer moderate lighting and do not require frequent fertilization. Over-fertilization can cause algae growth and harm the plant.

3. Reproductive Stage

The reproductive stage is the final stage of Anubias plant growth. At this stage, the plant has grown enough leaves to produce flowers. The flowers are small and white or greenish in color and usually bloom underwater.

It is important to note that Anubias plants do not usually flower in aquariums, as they require specific conditions to do so. If you want your Anubias plant to flower, you may need to provide it with emersed conditions (i.e., growing it above water level) or transfer it to a paludarium (a type of aquarium that mimics a natural habitat with both land and water).

Factors That Affect Anubias Plant Growth

Several factors can affect Anubias plant growth, including lighting, temperature, nutrients, water quality, and CO2 levels.

Lighting

Anubias plants prefer moderate lighting levels (around 2 watts per gallon). Too much or too little light can harm their growth.

Temperature

Anubias plants thrive in temperatures between 72-82°F (22-28°C). Avoid exposing them to extreme temperatures as they can damage or kill the plant.

Nutrients

Anubias plants are slow growers and do not require frequent fertilization. Avoid over-fertilizing as it can cause algae growth and harm the plant.

Water Quality

Anubias plants prefer slightly acidic water with a pH between 6.0-7.5. They also prefer soft water with a hardness level of 5-12 dGH.

CO2 Levels

Anubias plants do not require high CO2 levels but can benefit from additional CO2 supplementation in high-light setups.

How to Care for Anubias Plants at Each Stage

Emergent Stage Care

During the emergent stage, provide moderate lighting levels and ensure that the rhizome is planted just above the substrate surface. Avoid over-watering as it can lead to root rot.

Vegetative Stage Care

During the vegetative stage, provide moderate lighting levels and avoid over-fertilizing. Prune dead or damaged leaves regularly to promote healthy growth.

Reproductive Stage Care

During the reproductive stage, provide adequate lighting levels and avoid disturbing the flowers or buds. If you want your Anubias plant to flower in your aquarium, consider providing emersed conditions or transferring it to a paludarium setup.

FAQ Section

Q: Can I grow Anubias plants in low-light setups?

A: Yes, Anubias plants can be grown in low-light setups. However, they may grow slower than they would in moderate lighting conditions.

Q: Can I use CO2 supplementation for my Anubias plant?

A: Yes, you can use CO2 supplementation for your Anubias plant. However, they do not require high CO2 levels and can benefit from additional CO2 only in high-light setups.

Q: Can I fertilize my Anubias plant too much?

A: Yes, over-fertilizing can harm your Anubias plant by causing algae growth or even killing it.

Q: How often should I prune my Anubias plant?

A: You should prune dead or damaged leaves regularly during the vegetative stage to promote healthy growth.
