  • Giant Baby Tears (Micranthemum umbrosum) is highly sought-after for its ornamental appeal in aquascaping, vivariums, and terrariums due to its compact growth and vibrant green leaves.
  • It serves as a lush and visually appealing carpeting plant in aquariums, providing a naturalistic habitat for aquatic fauna and fostering a healthy ecosystem within the tank.
  • In outdoor gardens, it functions as an excellent ground cover, forming dense mats that suppress weed growth and maintain soil moisture.


Giant Baby Tears thrives in consistently moist environments and exhibits a strong affinity for water. When grown in aquatic settings, it requires well-oxygenated water to support healthy, vigorous growth. In terrariums and gardens, regular watering is essential to maintain optimal moisture levels in the soil.


  • Moderate to high light levels are conducive to the successful cultivation of Giant Baby Tears.
  • In aquariums, it flourishes under appropriate aquarium lighting, such as LED or fluorescent fixtures designed to support aquatic plant growth.
  • In terrariums and outdoor gardens, it thrives in partially shaded areas that offer filtered sunlight, as intense direct sunlight can lead to leaf burn and diminished vigor.


  • Supplemental fertilization can promote robust growth and vibrant foliage in Giant Baby Tears.
  • In aquatic environments, liquid fertilizers designed for aquarium plants can be added according to the manufacturer’s instructions to provide essential nutrients.
  • When cultivated in terrariums or outdoor settings, a balanced, water-soluble fertilizer formulated for ornamental plants can be applied at regular intervals during the growing season.


  • In aquatic environments, Giant Baby Tears can be planted in nutrient-rich substrates designed for aquatic plants, such as aquatic plant soil or specialized aquatic planting substrates.
  • In terrestrial settings, it thrives in well-draining, nutrient-rich soil with a slightly acidic to neutral pH range. A blend of quality potting mix and organic matter can provide an ideal growing medium.


Regular pruning is essential to maintain the compact, carpet-like appearance of Giant Baby Tears in both aquatic and terrestrial environments. Trimming the plant helps prevent overgrowth, encourages lateral growth, and enhances the overall aesthetic appeal.


Giant Baby Tears can be propagated through several methods, including:

  1. Division: The plant can be divided into smaller sections, each containing a portion of the root system and stem, which can then be replanted to establish new growth.
  2. Cuttings: Stem cuttings can be taken from healthy portions of the plant and planted in a suitable substrate to encourage the development of new roots and shoots.

Both methods offer effective means of expanding the plant population and cultivating new specimens for additional tanks, terrariums, or garden areas.
