Instead of counting the days until spring and fresh salads, get started indoors to enjoy nutrition-packed micro greens and baby lettuces within a few weeks. Micro greens are the baby leaves of vegetables like leaf lettuces, kale, spinach and radishes. They grow quickly indoors and are just the thing to zip up salads and sandwiches when the ground is still frozen outside.
Be sure to plant consecutive crops as you will want to keep the greens coming for a nonstop harvest of tasty greens.
How to Grow Micro Greens:
- Start with flat containers, plastic salad boxes or any item you can punch holes in for drainage.
- Fill containers with damp potting soil mixed with organic fertilizer.
- Scatter seeds across the soil surface and press firmly into soil with the palm of your hand.
- Cover containers with plastic lids or plastic wrap.
- Use a spray bottle to mist daily.
- Within 3-5 days, seedlings emerge.
- Move containers to a south-facing window or under grow lights, set for 12 hours daily.
How to Harvest Micro Greens:
- The first leaves that pop out of the soil are called seed leaves. These don’t look like the “true” plant. Once the first 2 sets of true leaves develop, start harvesting, about 10-14 days after planting.
- Snip the micro greens just above the soil level. When you’re finished snipping, you can begin the whole process over again!
- When harvesting lettuces, begin harvesting the outer leaves. The plant will continue to grow from the inside out, giving you a continuous harvest.
