Description

Common names: HM, Baby tears, Pearl weed, Manatee mudflower,
Amano pearl grass and Pearl grass

Pearl weed (Hemianthus Micranthemoides) is a popular aquatic plant, known for its bright green colour and quick growth. It is easy to care for and can be grown as a carpet, midground or background plant, depending on how often and where it is trimmed. Pearl weed is native to Florida, where it will grow in wet areas with still, stagnant water.

Pearl weed will grow, like most aquatic stem plants, by placing the stems into a substrate, which will begin to root. To propagate pearl weed, cut a piece of a mature and healthy plant, and bury it back into the substrate. If your aquarium has good lighting, the stems will quickly root into the substrate and continue to grow.

Basic Guide for Growing Pearl Weed:

• Lighting: Pearl Weed requires high-intensity lighting to maintain its compact growth and vibrant coloration.
• CO2 and Nutrients: Supplemental CO2 injection and regular fertilization are recommended for optimal growth.
• Water Parameters: It thrives in a temperature range of 68-82°F (20-28°C) with slightly acidic to neutral pH levels.
• Planting: Plant individual stems in the substrate, allowing space for horizontal growth and carpet formation.

Do's:

• Provide high-intensity lighting to promote compact growth and vibrant coloration.
• Maintain consistent CO2 levels and nutrient supplementation for optimal health.
• Regularly trim and replant to encourage horizontal growth and carpet formation.

Don'ts:

• Avoid shading Pearl Weed excessively, as it may result in leggy growth and reduced coloration.
• Be cautious with carbon dioxide injection to prevent overexposure and potential stress to the plant.
