Organic Mustard Seed

Each packet of Organic Mustard Seed has approximately 1700 seeds. Each plant will produce approximately 1-pound of fresh mustard.


Mustard is generally sown directly into the garden early in the spring. Use a soil thermometer to make sure soil is 45 °F before planting. Under perfect conditions, it takes 4-7 days for the mustard seed to germinate.


In order to grow the healthiest; best tasting mustard, the pH level of your garden soil should be 6.0-7.5. A soil tester will take the guess work out of determining the pH levels.


All of our Mustard seeds are OPEN-POLLINATED unless otherwise specified as a HYBRID. All of our organic been seeds are non-GMO!
