Watering persicaria amplexicaulis 'firetail' in a pot
Containers dry far faster than open ground, so persicaria amplexicaulis 'firetail' in a pot needs checking more often than the general guidance of "Keep evenly moist; water whenever the surface starts to dry, more in heat" — 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.
