Key Takeaways:
- Microgreens are harvested 7–14 days after sowing, making them one of the quickest edible crops to grow.
- Most microgreens thrive indoors year-round with bright light and consistent moisture.
- Shallow trays with drainage holes help prevent overwatering and root problems.
- Use fresh, untreated seeds specifically intended for growing or sprouting.
- Sow seeds densely but evenly for a full, healthy harvest.
- Cover trays during germination to improve sprouting, then uncover once seedlings emerge.
- Water from the bottom whenever possible to reduce mold and fungal diseases.
- Maintain good airflow around growing trays to keep plants healthy.
- Harvest with clean scissors just above the growing medium once the first true leaves begin to appear.
- Beginner-friendly varieties include broccoli, radish, kale, mustard, pea shoots, and sunflower.
- Most microgreens require no fertilizer because the seed contains enough nutrients for early growth.
- Succession planting every few days provides a continuous supply of fresh microgreens throughout the year.
Overview
Growing microgreens is one of the fastest and easiest ways to produce fresh, nutrient-dense greens at home. These young vegetable and herb seedlings are typically harvested 7–14 days after planting, just after the seed leaves (cotyledons) and, for many varieties, the first true leaves appear. Microgreens require very little space and can be grown year-round indoors using shallow trays, a quality growing medium, clean water, and either natural sunlight or full-spectrum grow lights. Common beginner-friendly varieties include broccoli, radish, kale, arugula, mustard, sunflower, and pea shoots. Proper moisture management, good airflow, and harvesting at the right stage help prevent mold while producing flavorful, tender greens. Research and extension gardening programs continue to highlight microgreens as an easy way to add fresh vegetables to your diet while maximizing limited growing space.
Microgreens are one of the easiest ways to add a concentrated source of nutrients to your daily meals. Think of them as a natural multivitamin you can enjoy in salads, sandwiches, smoothies, wraps, and grain bowls. Despite their small size, many microgreens contain significantly higher levels of nutrients per gram than their mature vegetable counterparts, with some varieties providing up to 40 times more nutrients by weight.
So, what makes these tiny greens so nutritious?
Rich in Vitamins
Microgreens are an excellent source of essential vitamins, including:
Vitamin A
B Vitamins
Vitamin C
Vitamin K
Packed with Essential Minerals
They also provide valuable minerals such as:
Manganese
Folate
And many other trace minerals that support overall health
Loaded with Antioxidants
Microgreens are naturally rich in polyphenols—powerful plant compounds that help protect your cells from oxidative stress. Diets high in polyphenols have been associated with improved heart health, healthier aging, and better cognitive function.
Potential Health Benefits
Emerging research suggests that regularly eating microgreens may help support a healthy weight while improving cholesterol levels by lowering LDL (“bad”) cholesterol and triglycerides. Although more human studies are needed, current findings highlight the impressive nutritional potential of these young greens.
By now, you can probably see why microgreens have become a favorite among gardeners, home cooks, and health enthusiasts alike.

Supplies for How to Grow Microgreens:
What You’ll Need to Grow Microgreens
1. Microgreen Seeds
I recommend purchasing a mixed variety of microgreen seeds for the best flavor and nutrition. My favorite approach is to combine a spicy seed mix with a mild seed mix before planting. This creates a diverse blend of around 10 different microgreen varieties in a single growing tray, giving you a colorful, flavorful, and nutrient-rich harvest.
2. Seed Starting Trays
Use a two-tray seed starting system for optimal drainage. The top tray should have drainage holes to prevent overwatering, while the larger bottom tray catches excess moisture and makes watering simple and mess-free.
3. Organic Potting Mix
Choose a high-quality organic potting mix that provides excellent drainage and nutrients for healthy microgreen growth. You can purchase a suitable organic potting mix here.
Method:
Fill a seed-starting tray about two-thirds full with a pre-moistened, organic seed-starting or potting mix, leveling the surface gently.
Evenly scatter the microgreen seed blend over the soil. For a standard 12 x 12-inch tray, approximately 1 teaspoon of seeds provides excellent coverage.
Lightly cover the seeds with 1/4 inch of additional potting mix, ensuring they remain evenly protected while allowing for successful germination.
Place the tray in a warm indoor location, such as a kitchen counter or shelf. Direct sunlight is not required during the germination stage. Within a few days, the seeds will sprout, and delicate green shoots will begin emerging through the soil. In about 7 to 10 days, your fresh, nutrient-rich microgreens will be ready to harvest. Simply snip them just above the soil line and enjoy them in salads, sandwiches, wraps, smoothies, or as a flavorful garnish.
Harvest your microgreens by snipping them just above the soil line once they reach about 2 to 2½ inches (5–6 cm) tall. For the best flavor and nutrition, enjoy them immediately after harvesting.
Microgreens are incredibly versatile. Sprinkle them over avocado toast, toss them into fresh salads with lettuce, sunflower shoots, and pea shoots, or layer them into sandwiches, wraps, grain bowls, soups, and smoothies for a vibrant burst of flavor, texture, and nutrients.
Enjoy every bite! One of the biggest advantages of growing microgreens is that you can harvest fresh greens indoors all year long. They provide a convenient source of vitamins, minerals, antioxidants, and phytonutrients, making them an excellent addition to your diet—especially during the colder months when fresh garden produce may be limited.
