The buckwheat plant (Fagopyrum esculentum) is a fast-growing, herbaceous plant known for its ability to thrive in poor soil conditions and colder climates. It features broad, heart-shaped leaves and small, fragrant white or pink flowers that attract pollinators like bees.
The plant produces triangular seeds, which are harvested and used as a grain alternative, though technically, buckwheat is not a true cereal grain. Its ability to grow quickly and suppress weeds makes it a popular choice in sustainable farming and as a cover crop.
The buckwheat plant is valued for its role in improving soil health and providing a gluten-free food source rich in nutrients.
How to Grow Buckwheat

Growing buckwheat improves soil health by suppressing weeds and adding organic matter through its rapid growth and dense foliage. It also attracts beneficial insects, making it a great choice for pollinator-friendly gardens.
Planting Buckwheat:
- Timing: Plant buckwheat in late spring or early summer, after the last frost. It’s best suited for warm weather, with temperatures between 50-90°F.
- Soil: Buckwheat thrives in well-drained, moderately fertile soils. It can tolerate poor soils but doesn’t do well in heavy clay.
- Spacing: Sow seeds directly into the soil, about 1-2 inches apart and 1/2 to 1 inch deep. If planting in rows, space rows about 6-8 inches apart.
- Watering: Keep the soil moist until germination, which usually happens within 5-7 days.
Growing Buckwheat:
- Care: Buckwheat is low-maintenance. It grows quickly and shades out weeds, so minimal weeding is needed.
- Water: Buckwheat is drought-tolerant but benefits from occasional watering during dry spells.
Harvesting Buckwheat:
- Timing: Buckwheat is ready to harvest in about 10-12 weeks. Harvest when 75% of the seeds turn dark brown or black.
- Method: Cut the plants close to the ground and allow them to dry for several days. Thresh the plants by beating them to release the seeds, and winnow to remove the chaff.
