Watering mary washington asparagus in a pot
Containers dry far faster than open ground, so mary washington asparagus in a pot needs checking more often than the general guidance of "Weekly deep watering in the first two seasons; established beds need water only in drought" — 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.
