Compost and drainage

Watering matthiola incana 'giant imperial mix' in a pot
Containers dry far faster than open ground, so matthiola incana 'giant imperial mix' in a pot needs checking more often than the general guidance of "Keep evenly moist; water every 3-5 days, adjusting to weather" — especially in summer, wind, or a heated room.

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.
