The Pond Guy Water Lettuce

No, Water Lettuce is a free-floating plant. It absorbs all necessary nutrients directly from the pond water through its submerged roots, so it does not need to be planted in soil or substrate.

Water Lettuce is tropical and thrives in hardiness zones 9 to 11. It requires a minimum water temperature of 65°F, so it will not survive freezing temperatures and should be treated as an annual in colder climates.

This plant prefers partial to full shade. While it can tolerate some light, too much direct, intense sun can scorch the leaves, so placing it in an area of your pond that receives filtered light or shade is ideal.

Water Lettuce has a fast growth rate and propagates quickly via runners. You can expect the plants to multiply and spread across the surface of your pond throughout the growing season.

No, Water Lettuce does not require supplemental CO2 or fertilizers. It is highly efficient at absorbing excess nutrients directly from the pond water, which actually helps improve your water quality.

It is very low-maintenance. The only care required is the occasional pruning of any yellowing or decaying leaves to keep the plant healthy and your pond looking tidy.
