Buckwheat Microgreens

Fagopyrum esculentum

Buckwheat is widely grown as a grain crop, bee pasture, soil improving cover crop and as wildlife cover. It is a warm season grain which grows rapidly during the summer and several crops per year may be had with proper management. This rapid and dense growth chokes out weeds and is used in crop-free fields in rotation with vegetables. Buckwheat is often grown to attract beneficial insects and as pasture for honey bees. Sow in late May through July and till in about a month later, when flowering has begun. For grain harvest, sow 3 months before fall frost. Harvest after killing frost.

Harvesting

Winged achene with 3 sides. The wings of this achene form a heart-like shape with smooth edges. The achenes can be blown about by the wind because of their sizable wings.

Color: Brown/Copper. Type: Achene. Length: < 1 inch. Width: < 1 inch.

Garden value: Edible

Harvest time: Fall

Bloom time: Fall, Summer

Edibility: Cooked seeds can be eaten as a cereal grain.

Storage & Preservation

Fresh buckwheat microgreens store exceptionally well compared to more delicate varieties. After harvesting, gently rinse in cool water and spin dry in a salad spinner or pat dry with paper towels. Store in airtight containers lined with paper towels in your refrigerator at 35-40°F.

Properly stored buckwheat microgreens maintain their crisp texture and tart flavor for 7-10 days – significantly longer than most microgreens. Change the paper towel liner if it becomes damp to prevent moisture buildup.

For preservation, dehydrating works beautifully with these substantial leaves. Use a dehydrator at 95°F for 8-12 hours until crispy, then store in airtight containers for up to 6 months. The dried microgreens make excellent seasoning for soups and salads. You can also freeze them in ice cube trays with a little water for smoothie additions, though they'll lose their crisp texture when thawed. Avoid traditional canning methods as the delicate cellular structure breaks down under high heat processing.

Frequently Asked Questions

How long do buckwheat microgreens take to grow?▼

Buckwheat microgreens typically take 8-12 days from seeding to harvest. You'll see initial germination within 24-48 hours, making them one of the fastest-sprouting microgreen varieties. The exact timing depends on temperature and growing conditions, with warmer conditions (70-75°F) speeding up the process.

Are buckwheat microgreens good for beginners?▼

Yes, buckwheat microgreens are excellent for beginners due to their forgiving nature and reliable germination rates. They're naturally disease-resistant, tolerate minor watering mistakes better than delicate varieties, and their large seeds are easy to handle. The substantial leaves also make harvesting straightforward compared to tiny, fragile microgreens.

Can you grow buckwheat microgreens without soil?▼

Absolutely! Buckwheat microgreens grow excellently on coconut coir, hemp mats, or even paper towels. Many commercial growers prefer soilless mediums because they're cleaner, reduce contamination risk, and make harvesting easier. Just ensure whatever medium you choose retains moisture while providing good drainage.

What do buckwheat microgreens taste like?▼

Buckwheat microgreens have a fresh, slightly tart flavor reminiscent of lemon or rhubarb with a crisp, substantial texture. They're much more robust than typical microgreens, offering a pleasant tang without bitterness. The flavor intensifies slightly as they mature, making timing important for your preferred taste profile.

Do buckwheat microgreens contain gluten?▼

No, buckwheat microgreens are completely gluten-free despite the confusing name. Buckwheat isn't related to wheat at all – it's actually a pseudocereal related to rhubarb. This makes buckwheat microgreens safe for people with celiac disease or gluten sensitivity.

How much do buckwheat microgreens yield per tray?▼

A standard 10x20 inch tray typically yields 12-16 ounces of fresh buckwheat microgreens, significantly more than most microgreen varieties due to their large, substantial leaves. Using 1.5-2 ounces of seeds per tray usually provides optimal density for maximum yields without overcrowding.
