Sowing Months Harvest Months
  • Sow at any time of the year. Place 4 layers of kitchen/tissue paper on a saucer and moisten, allowing any excess water to drain away.
  • Sprinkle the seed thinly on the paper and place the whole saucer into a polythene bag and seal it.
  • Alternatively, sow onto vermiculite in pots or shallow trays on the windowsill and keep moist at all times.
  • Mustard will be ready to cut in 5 days from sowing.
  • To grow mustard and cress together, sow the cress seeds 3 days before sowing the mustard seeds. So they will be ready at the same time.
