Growing Nutrient-Rich Greens from Seed in March in Zone 6

by

March is an exciting time for gardeners in Zone 6, signaling the beginning of the growing season. One of the most rewarding crops to start early is nutrient-rich greens, which can be grown from seed indoors or directly sown outdoors as soon as the soil is workable. These greens not only provide essential vitamins and minerals but also add vibrant color and flavor to your meals.

Choosing the Right Greens to Grow in March

  • Spinach
  • Kale
  • Swiss chard
  • Lettuce (varieties like Romaine and Butterhead)
  • Arugula

These greens are hardy and can tolerate the cool temperatures typical of early spring in Zone 6. They are also quick to mature, providing fresh greens in just a few weeks.

Starting Greens from Seed

There are two main methods to start greens in March: direct sowing outdoors or starting seeds indoors for later transplanting. Each method has its advantages depending on your gardening setup and local weather conditions.

Direct Sowing Outdoors

If the soil has warmed enough and there is no longer a risk of frost, you can sow your seeds directly into the garden bed. Prepare the soil by loosening it and mixing in compost to provide nutrients. Sow the seeds about ½ inch deep and space them according to the variety’s recommendations.

Starting Seeds Indoors

To get a head start, plant your seeds in seed trays or pots indoors. Use a quality seed-starting mix and keep the soil moist. Place the trays in a warm, bright location or under grow lights. Transplant the seedlings outdoors once they have developed a few true leaves and the weather permits.

Caring for Your Greens

Proper care ensures healthy, nutrient-dense greens. Keep the soil consistently moist but not waterlogged. Mulching can help retain moisture and regulate soil temperature. Thin seedlings to avoid overcrowding, which can lead to disease and poor growth.

Tips for Success

  • Use cold frames or row covers to protect young plants from late frosts.
  • Maintain even soil moisture through regular watering.
  • Fertilize lightly with a balanced, organic fertilizer to promote healthy growth.
  • Harvest greens regularly to encourage new growth and prevent bolting.

Growing nutrient-rich greens from seed in March in Zone 6 is a rewarding way to kick off your garden season. With careful planning and attention, you can enjoy fresh, healthy greens for salads, smoothies, and cooking throughout the early spring.
