Watermeals is a unique plant genus comprising the smallest flowering plants in the world. Basic care needs include sunlight exposure, immersion in fresh water, and moderate temperatures. The plants prefer a nitrogen-rich environment and thrive in water bodies like ponds and lakes, as they can rapidly absorb nutrients from the water. Common challenges include pollution, changing water conditions, nutrient deficiency, and competition with algae. Seasonal concerns mostly revolve around colder climates, where watermeals species may need protection to avoid frost damage.
