Growing mustard greens in your garden is a simple and rewarding process, whether you are a seasoned gardener or a beginner.

To get started, you can either plant mustard greens from seeds or seedlings.

Planting outdoors can begin three weeks before your last frost date, ensuring a healthy and continuous supply of this delicious and versatile leafy green.

About Mustard Greens

Mustard greens are part of the Brassica juncea species in the cabbage family.

They are an annual plant native to Asia and Africa, known for their pungent flavor and versatile uses in various cuisines.

To grow mustard greens successfully, choose a suitable variety based on your preference and location.

Plant your mustard greens seeds or seedlings in fertile, well-drained soil with a pH between 6.0 and 7.5, ensuring they receive full sun or light partial shade.

Growing Mustard Greens

To start planting mustard greens in your garden, sow seeds directly into the soil about a half inch (1 cm) apart in rows one to two feet apart.

Begin this process three weeks before your last frost date in spring or fall when the weather is cooler than 75 degrees F.

Once the seeds have sprouted, thin the seedlings to 3 inches (8 cm) apart.

Plant seedlings 3 to 5 inches (8-13 cm) apart instead of seeds if you're using transplants.

Mustard greens grow best in cool seasons, and a mild frost enhances their flavor.

Caring for Mustard Greens

Sun and Temperature

Mustard greens prefer full sun but can tolerate partial shade. They thrive in cool-season temperatures, ideally between 45°F and 75°F.

Water and Humidity

Water regularly, keeping the soil consistently moist but not soggy. Mustard greens don't require high humidity.


Choose a well-drained soil with a pH between 6.0 and 7.5. Add compost or well-aged manure to ensure the soil is rich in organic matter.


Fertilize with a nitrogen-rich fertilizer when planting and again mid-season. Feed container-grown mustard greens every 3-4 weeks.


If growing mustard greens in containers, ensure the size suits the plant's growth.

Repot if the plant becomes root-bound or if you transplant seedlings to a larger container.

Pruning and Propagation

Regularly harvest the outer leaves for a continuous crop. Optionally, thin seedlings encourage healthy growth by providing adequate spacing between plants.

Troubleshooting Plant Problems

Growing Problems

Sometimes, mustard greens don't germinate due to issues with the seeds or soil. If this happens, perform a seed viability test and check the soil.

Mustard greens are a cool-season crop, so avoid planting them in summer.

Plant seeds at the end of spring, then plant again in mid-summer for a fall harvest. Sow seeds just under the soil, about 0.5 inches (1 cm) apart.

Pests and Diseases

Mustard greens may experience pest issues from flea beetles, aphids, cabbage worms, and slugs.

Keep an eye out for these pests and address infestations early to minimize damage.

Diseases like downy mildew and anthracnose can also threaten your mustard greens.

To minimize risk, practice crop rotation, provide proper spacing, and maintain soil health.

Companion Planting

Consider companion planting with lettuce or other cool-season leafy greens to promote healthier growth for your mustard plants.

Companion planting can also help deter pests and boost overall garden health.

However, avoid planting mustard greens near other brassicas, such as cabbage or broccoli, as they share similar pests and diseases.
