Compost and drainage

Pygmy Water Lily likes steady moisture but not waterlogging — a tricky balance in a pot. Use a good peat-free compost with some added perlite for air, make sure the container drains freely, and mulch the surface to slow evaporation.

Watering pygmy water lily in a pot

Containers dry far faster than open ground, so pygmy water lily in a pot needs checking more often than the general guidance of "Permanently aquatic — crown submerged 10–25 cm (4–10 in) below water surface" — especially in summer, wind, or a heated room. Check the top few centimetres with a finger rather than watering on a fixed day.

Potting on

Pot on when roots show through the drainage holes or growth slows noticeably — usually every 1-2 years for a plant this size. Move up one pot size only; jumping several sizes leaves wet compost the roots cannot reach, and that is what rots them.
