Growing water violet in a pot
Compost and drainage
Use a quality peat-free compost with a handful of perlite for air, and make sure the pot has drainage holes. Compost in containers compacts over time, which suffocates roots — that is the main reason potted plants decline.
Watering water violet in a pot
Containers dry far faster than open ground, so water violet in a pot needs checking more often than the general guidance of "Fully submerged aquatic; grows in 20–80 cm of water" — 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.
