Can you grow Mizuna on a balcony?
Brassica rapa nipposinica
Yes — great in containers
Mizuna (Brassica rapa nipposinica) grows well on a balcony in a pot of at least 15 litres. It needs partial shade — around 3+ hours of direct sun a day. Ready in about 20 days; ideal as cut-and-come-again, giving repeated harvests of young leaves over several months. All figures below are sourced from RHS and the Old Farmer's Almanac.

Good companions: Grows well among other brassicas as a quick catch crop
Balcony tip: Use a container at least 30cm wide, as smaller pots dry out too fast; space plants 10–15cm apart for repeated small-leaf pickings
