How to Plant Mustard Seeds
If growing outdoors, plant the mustard seed about three weeks before your last frost date, or anytime indoors.
Since you will be harvesting the mustard seed, there is no need to space out plantings like you do with mustard greens. (Read more: Moving Plants Inside for the Winter: What You Need to Know)
Plant your mustard seeds about an inch apart. Once they sprout, thin the seedlings so they are 6 in. apart.
Mustard plants grown for seed are planted further apart than plants grown for leaves, as the mustard plant will be getting much larger before it flowers.
Growing the Seeds
Once mustard seed plants start growing, they need little care. They enjoy cool temperatures and will bolt (flower) quickly in warmer temperatures.
While this may seem like a great thing if you are looking to grow mustard seeds, it is not. Mustard plants that bolt due to warm weather will produce poor flowers and seeds. It is best to keep plants on a normal flowering cycle.
Mustard seed plants need 2 in. of water a week. They do not need fertilizer if they have been planted in well-amended garden soil, but if you are unsure if your soil is nutrient rich, you can add a balanced fertilizer to the roots once the plants are 3 or 4 in. tall.
How to Harvest Mustard Seeds
Mustard plants will eventually flower and go to seed. The flowers are generally yellow, but some varieties have white flowers. As the mustard flower grows and matures, it will form pods. Watch for these pods to start to turn brown.
Another sign that you are nearing harvest time is that the leaves of the plant will start to yellow. Be careful not to leave the pods on the mustard seed plant for too long as they will burst open when fully ripe and the mustard seed harvest will be lost.
The next step is to remove the seeds from the pods. You can do this with your hands, or you can place the flower heads in a paper bag and allow them to finish maturing.
The pods will open on their own in 1-2 weeks and a gentle shake of the bag will shake loose most of the mustard seeds.
Mustard seeds can be used fresh, but like other herbs and spices, if you plant on storing them long term, they will need to be dried.
