How to Grow Mustard Greens in Containers Step-by-Step

I’ve grown mustard greens in containers for years, especially when I want an easy, portable crop for fresh salads and stir-fries. Mustard greens adapt well to pots, making them a great choice for gardeners with limited space, patios, or balconies. Here’s my proven step-by-step method.

Step 1: Choose the Right Container

Use a container at least 8–10 inches deep with good drainage holes.
A 12-inch-wide pot can grow 3–4 mustard plants comfortably.

Step 2: Select the Right Soil

Use a loose, well-draining potting mix rich in compost.
Avoid heavy garden soil—it compacts and slows growth.

Step 3: Plant Seeds or Seedlings

Sow seeds directly ¼–½ inch deep.
For continuous harvest, sow new seeds every 2–3 weeks.
Thin seedlings to about 6 inches apart.

Step 4: Provide Sunlight

Mustard greens thrive in 6+ hours of sunlight daily.
In hotter climates, provide light afternoon shade to prevent bolting.

Step 5: Water Consistently

Keep soil evenly moist—container soil dries out faster.
Water deeply when the top inch feels dry.

Step 6: Feed for Leafy Growth

Use a balanced organic fertilizer every 3–4 weeks.
Fish emulsion or compost tea works well for steady growth.

Step 7: Harvest Regularly

Begin harvesting tender leaves when 4–6 inches long.
Pick outer leaves first, allowing the center to keep growing.
For baby greens, harvest the entire plant at 3–4 weeks.

My Experience

In my container garden, I’ve found that mustard greens grow quickly and reliably when given rich soil and steady water. By reseeding every few weeks, I keep a constant supply of greens right outside my kitchen door. Container growing also makes it easier to manage pests like flea beetles—I simply move pots around when needed.
