Description
Introduction
Duckweeed is a tiny floating perennial and the smallest flowering plant in the world. Despite its size, it provides important benefits in koi and goldfish ponds. It covers the water surface, moderates temperature, and offers shaded areas for fish to reduce stress and promote health.
How Duckweeed Improves Pond Health
This plant floats naturally and spreads across calm water surfaces. Its coverage helps limit sunlight, reduce harmful UV rays, and slow algae growth. Shaded areas created by Duckweeed keep the water cooler and provide a safer environment for fish, helping them thrive in summer heat.
Benefits for Koi and Goldfish
Fish often graze lightly on the plant’s surface. This provides supplemental nutrition and natural enrichment. The plant also creates hiding spots and shaded areas, which reduces stress and encourages natural behavior.
Growth and Care
Duckweeed grows well in nutrient-rich, calm water with full sun to partial shade. It requires minimal maintenance and adapts to most pond conditions. Fast growth can be managed by occasional thinning, but in ponds with active fish, natural grazing keeps the plant balanced.
Why Add Duckweeed to Your Pond?
Adding Duckweeed enhances the pond’s visual appeal while promoting ecological balance. It offers shade, surface coverage, and supplemental nutrition for fish, all in a low-maintenance, easy-to-grow floating plant.

The table below shows the estimated shipping and pick-up weeks for destinations to USA states. These dates can change depending on weather and how strong the plants are at that time.
For example, a wet spring will have many clouds leading to less sunshine. Thus, the plants may need a bit longer to grow strong enough for transplanting and transit. With the planet heating up, a warm spring may help the plants grow strong enough to ship before the dates in this table.
