Spinach microgreens are tender, nutrient-packed young greens harvested when just 1 to 3 inches tall. They feature vibrant green leaves with a delicate, juicy texture and a mild, slightly sweet flavor touched with earthy undertones. While similar to mature spinach, their taste is more concentrated, making them versatile in both raw and cooked dishes.
Ready in as little as 10 to 20 days, these microgreens are excellent for quick, nutrient-dense harvests. They are rich in vitamins A, C, and K, as well as iron, calcium, and powerful antioxidants, delivering a concentrated nutritional boost in a small package.
In the kitchen, spinach microgreens shine in salads, sandwiches, and wraps, where their fresh taste blends beautifully with other ingredients. They can be blended into smoothies and juices to enhance nutrition without overpowering flavors, or sprinkled as a garnish over soups, omelets, stir-fries, and roasted vegetables. Their delicate leaves also add a wholesome lift to breakfast dishes like quiches and scrambles.
With their quick growth, exceptional flavor, and strong nutrition, spinach microgreens are an easy and rewarding crop for home growers and chefs alike—bringing a touch of freshness and vitality to everyday meals.
Planting Instructions for Spinach Microgreen Seeds
When to Plant
Spinach microgreens take a little more patience than some of the faster crops, but they’re well worth it. Expect them to be ready in about 10 to 20 days, depending on temperature and light. If you’d like a steady harvest, start a new tray every two weeks. Keep in mind that spinach microgreens don’t grow back once cut, so succession planting is the best way to enjoy a continuous supply.
Where to Plant
Use a shallow tray or container with drainage holes, set inside another tray to catch extra water. Place your tray in a sunny windowsill or under grow lights for 12–16 hours of light per day. If you’re using natural light, rotate your tray each day so the seedlings grow straight instead of leaning toward the sun. A small fan set on low nearby can keep the air moving, strengthen stems, and help prevent mold.
How to Plant
-
Fill a shallow tray with about one to two inches of moist seed-starting mix, coconut coir, or another fine, clean medium.
-
Smooth the surface gently, but don’t pack it down.
-
Scatter spinach seeds evenly across the top, pressing them lightly into the medium. Since spinach seeds are a little larger, it’s best to cover them with a thin layer of soil—just enough to keep them moist without burying them deeply. For quicker germination, you can soak the seeds in water for 6–8 hours before planting.
-
Mist the surface with a spray bottle, then cover the tray with a humidity dome, another tray, or a cloth to hold in moisture until sprouts appear.
Growing
Spinach seeds can take longer to sprout than fast crops like radish or broccoli, so don’t worry if they seem slow at first. Once you see green shoots, remove the cover and give them steady light. If you’re using grow lights, keep them about one to two inches above the plants. If you’re using a windowsill, rotate your tray daily for even growth. Water from below by pouring water into the bottom tray so the soil wicks it upward—this keeps the leaves dry and reduces the risk of disease.
Harvesting
Harvest spinach microgreens when they are one to three inches tall, usually within 10 to 20 days. Use clean scissors or a sharp knife to cut the greens just above the soil line. At this stage, the leaves are tender, juicy, and bright green, with a mild flavor that combines sweetness and a gentle earthy note—like concentrated baby spinach.
Storage
Spinach microgreens are best enjoyed right after harvest for the best flavor and nutrition. If you need to store them, place the unwashed greens in an airtight container lined with a paper towel and refrigerate for up to five days. Rinse gently with cool water just before eating.
FAQ:
How long do spinach microgreens take to grow?
Spinach microgreens usually reach harvest in about 10 to 20 days. Warmer temperatures, steady light, and good moisture can help them grow faster.
What lighting do spinach microgreens need?
Provide bright, consistent light for 12–16 hours daily. A sunny window works, but grow lights one to two inches above the canopy produce straighter stems and deeper color when outdoor lighting is poor. Rotate window-grown trays daily to prevent leaning.
Should I soak spinach microgreen seeds before planting?
A six to eight hour soak can speed germination for this slower sprouter, but it is optional. Drain well before sowing so seeds don’t clump. If you skip soaking, just keep surface moisture even until germination.
How do I plant spinach microgreens?
Fill a shallow tray with one to two inches of moist, fine seed-starting mix or coconut coir. Broadcast seeds evenly, press gently, and cover with a thin layer of medium to keep them moist. Mist, then cover with a humidity dome or an inverted tray until you see sprouts emerging.
What conditions help them sprout evenly?
Aim for a room temperature around sixty-eight to seventy-two degrees and keep the top layer evenly damp, not soggy. A light blackout period (two to three days under a cover) helps uniform germination; remove the cover at first sign of green.
When and how do I harvest spinach microgreens?
Harvest at one to three inches tall—usually cotyledons plus the first true leaves. Use clean scissors to cut just above the surface so no grit gets into the greens. They will not regrow, so plan your next tray ahead.
What do they taste like and how do I use spinach microgreens?
Mild, fresh, slightly sweet with a gentle earthy finish—like concentrated baby spinach. Excellent in salads, sandwiches, wraps, omelets, and as a smoothie boost that does not overpower other flavors. They also finish soups or roasted vegetables beautifully!
How should I water and prevent issues while growing spinach microgreens?
After uncovering, switch to bottom watering: add water to the catch tray so the medium wicks it up. This keeps leaves dry and reduces mold risk. A small fan on low improves airflow and strengthens stems.
How do I store harvested spinach microgreens?
Use them fresh for best flavor. For short storage, place unwashed greens in an airtight container lined with a paper towel and refrigerate up to five days; rinse gently with cool water just before eating.
