Minute duckweed
Also known as: Tropical duckweed
Minute duckweed is a tiny aquatic plant that typically forms green carpets across still water surfaces. This free-floating species possesses minuscule, flat, oval fronds that cluster in groups, creating a lush, diminutive mat. Minute duckweed thrives in nutrient-rich freshwaters, reproducing rapidly and contributing to the ecosystem by providing food for aquatic life and shelter for microorganisms.

Water: Native to calm freshwater habitats, minute duckweed thrives in consistently moist conditions and has a high water content in its small fronds. It requires weekly watering and is adaptable to fluctuating water levels, making it suitable for studies on aquatic plant resilience.
Fertilize: Minute duckweed requires a balanced liquid fertilizer monthly during growing seasons for optimal growth. Adjust quantities based on plant size and seasonal dormancy. Over-fertilization can cause algae problems, so observe closely. Always dilute according to label instructions to protect minute duckweed's ecosystem.
Pruning: Minute duckweed is characterized by small, floating leaves. Regular pruning in early to late spring helps control growth, reduce nutrient depletion, and improve water quality. Focus on removing older, yellowing parts while avoiding over-pruning to maintain its ecological role.
Propagation: Minute duckweed is a small aquatic plant that reproduces mainly through vegetative fragmentation, forming dense colonies. It disperses via water currents or animals, though controlled propagation can be achieved by redistributing fragments. Minute duckweed thrives with sufficient light and nutrients.
