When winter’s chill settles in and your garden beds are blanketed in frost, it’s easy for gardeners to feel the itch to get back to cultivating something green. Fortunately, growing microgreens indoors offers a perfect solution to banish the winter blues. These tiny, nutrient-packed plants can be grown quickly and easily in the comfort of your home, bringing freshness and vitality to your meals while keeping your gardening spirit alive.
Here’s a comprehensive guide to growing microgreens indoors during January and February—a satisfying way to bridge the gap until spring.

What are microgreens?
Microgreens are young plants harvested at an early stage of development, just after their first true leaves appear. Despite their small size, they pack a big punch in terms of flavor, nutrition, and visual appeal. Popular microgreens include:
Radish
Arugula
Broccoli
Sunflower
Peas
Cilantro
Basil
Their short growing time—usually seven to 21 days—makes them an ideal indoor gardening project during winter.

Why grow microgreens in winter?
Winter can feel like an uninspiring time for gardeners, with limited outdoor opportunities to plant or harvest. Growing microgreens indoors offers several benefits:
Quick results: Some varieties are ready to harvest in as little as a week, providing instant gratification.
Minimal space required: A sunny windowsill, countertop, or a small shelf with grow lights is all you need.
No special equipment needed: Basic supplies like trays, soil, and seeds make it easy to get started.
Nutritional boost: Microgreens are rich in vitamins and minerals, adding a fresh, healthy touch to winter meals.
Therapeutic value: Caring for plants has been shown to reduce stress and improve mood—perfect for combating winter doldrums.

What you’ll need to grow microgreens
Starting a microgreens garden is simple and affordable. Gather these materials:
Seeds: Choose seeds labeled for microgreens or organic vegetable seeds. Avoid seeds treated with fungicides.
Growing trays: Shallow trays (2-3 inches deep) with drainage holes are ideal. Recycled containers like takeout trays can also work.
Growing medium: Use seed-starting mix, coconut coir, or another light, well-draining medium.
Light source: A sunny windowsill works well, but grow lights are great if natural light is limited.
Spray bottle: Useful for misting seeds and seedlings.

Step-by-step guide to growing microgreens
1. Prepare the tray
Fill the tray with one to two inches of your chosen growing medium. Smooth the surface but avoid compacting the soil.
2. Sow the seeds
Evenly sprinkle seeds over the soil surface, spacing them densely but not overlapping excessively. Lightly press seeds into the soil without burying them.
3. Water and cover
Mist the seeds gently with water using a spray bottle. Cover the tray with a clear lid, plastic wrap, or another tray to create a mini greenhouse effect.
4. Provide light and warmth
Place the tray in a warm, bright location. If using grow lights, position them four-six inches above the tray and keep them on for 12-16 hours daily.
5. Monitor growth
Remove the cover once seeds sprout, typically within two-five days. Mist daily to keep the soil moist but not soggy. Rotate the tray occasionally to ensure even light exposure.
6. Harvest time
When the microgreens are one-three inches tall and have their first true leaves, they’re ready to harvest. Use scissors to cut them just above the soil line.
7. Enjoy your harvest
Rinse the microgreens gently and add them to salads, sandwiches, smoothies, or as a garnish for soups and entrees.

Troubleshooting tips
Mold or fungus: Ensure proper ventilation and avoid overwatering. A small fan can help improve air circulation.
Uneven growth: Ensure all areas of the tray receive consistent light. Rotate trays regularly if using natural light.
Leggy microgreens: This often indicates inadequate light. Consider growing lights if this occurs.

Creative ways to use microgreens
Microgreens are versatile and can enhance your indoor space in creative ways. Use them as:
A vibrant centerpiece for your kitchen counter.
A thoughtful gift for friends and family who enjoy fresh greens.
A fun educational project for kids during winter break.
