Humidity
Field Mustard doesnât require additional humidity. Plants absorb most water through their root system rather than their leaves, so the best way to provide humidity for your plants is through watering the soil.

Field Mustard grows very slowly and doesnât require added fertilizer. Replacing your plantâs potting soil once a year should provide them with more than enough nutrition. Remember, plants get their energy from sunlight, not fertilizer!
