Care Instructions
Greater duckweed thrives in bright, indirect light and prefers moderate temperatures. It requires high humidity and should be kept in waterlogged conditions. This plant is easy to care for and can grow both indoors and outdoors in suitable water bodies.Soil
Spirodela polyrhiza does not require traditional soil as it is an aquatic plant. It thrives in nutrient-rich water with a loamy substrate. Ensure the water is clean and well-oxygenated for optimal growth.Fertilizer
Use a balanced aquatic plant fertilizer with an N-P-K ratio of 10-10-10. Fertilize monthly during the growing season to support its rapid growth.Repotting
Repotting is not typically required for Spirodela polyrhiza as it is a free-floating plant. However, if grown in a container, ensure the water is refreshed regularly to maintain nutrient levels.Propagation
Propagation is straightforward as the plant naturally multiplies by producing daughter plants. Simply separate the daughter plants and place them in a new water body or container.Pruning
Pruning is not necessary for Spirodela polyrhiza. However, you may need to thin out the plant if it becomes too dense to ensure adequate light and nutrient distribution.Toxicity
Spirodela polyrhiza is not toxic to pets or humans. It is safe to handle and can be used in aquariums and ponds without concern for toxicity.Additional
