Why Grow Mustard Greens?

Fast-growing: Ready to harvest in as little as 20–30 days.
Cold-hardy: Thrives in cool spring and fall weather.
Nutrient-rich: Packed with vitamins A, C, and K.

Where to Plant Mustard Greens

Choose a sunny location (6+ hours of sunlight).
Grow in loose, fertile, well-draining soil rich in compost.
Mustard greens tolerate light shade, especially in warm weather.

Watering Mustard Greens

Keep soil consistently moist but not waterlogged.
Water deeply once or twice a week, more often in containers.
Even watering prevents bitterness and bolting.

Feeding Mustard Greens

Work compost into the soil before planting.
Side-dress with a balanced organic fertilizer every 3–4 weeks.
Avoid over-fertilizing with nitrogen; it leads to lush growth but weaker flavor.

Caring for Healthy Growth

Thin seedlings to 6–8 inches apart for full-sized leaves.
Mulch to keep soil cool and retain moisture.
Watch for flea beetles and aphids; use row covers or organic sprays if needed.

My Experience Tip

In my Sonoma Valley garden, I find mustard greens taste sweetest when grown in cool fall weather. They’re one of the first crops I plant in late summer and one of the last I harvest before winter sets in.
