Fagopyrum esculentum Warm season cover crop

Non-legume broadleaf does not fix Nitrogen but is one of the best hot weather cover crops because of its ability to produce organic matter and smother summer weeds (Canada Thistle, Quackgrass, Nutgrass, etc) quickly. Also accumulates insoluble phosphorus and, when turned under, releases it to the soil in plant-available form.

  • Application Rate: 3 lb/1000 sq ft or 60-80 lb/acre
  • Inoculant: None needed
  • Germination: 5-10 Days
  • Plant Height: 8" - 3'
  • Days to Maturity: 30-45
  • Uses: Planted early, it is an excellent trap crop for thrips during bloom of fruits and vines. Also attracts beneficial insects. Weed competition, accumulates phosphorus for later release.
  • Facts to Note: Grows on almost any soil with little assistance, but absolutely requires warmth. Quick to mature, so 2 to 4 plantings can be sown in one summer. Mature height varies with soil quality.


  • Adds Significant Organic Matter
  • Attracts Bees/Butterflies
  • Attracts Beneficial Insects
  • Easily Established
  • Good for Weed Competition
  • Loosens Heavy Soils
  • Requires Summer Water
  • Somewhat Drought Tolerant

Zone 5B. Trying to expand my garden, soil is so hard can't get a shovel into it. Mowed area as close as I can, covered with cardboard, covered cardboard with kitchen veggie waste (mostly tea bags, coffee grounds and filters) with some rabbit waste. Scattered with buckwheat seeds covered with some dirt from planting bushes in the yard. Buckwheat came up in 4 days, flowered after 27 days, pulled it all up 9 days (36 days total) later at 2 feet tall. The kitchen scraps have pretty much rotted down and I have only about 1 inch of "soil?" that the buckwheat grew in. Now I have beautiful buckwheat to compost in place making the soil a little deeper. Another cover crop or 2 this year then english peas in the spring followed by maybe a bean crop and I'll have some soil.

Fast grower

Ordered this to try to correct a novice mistake (bare garden ground over winter + no til gardening!) -- We planted it just as directed and had a very pretty ground cover within 3 days; 2 weeks in and it's about 4 inches high!

This buckwheat is wonderful for the warm climate of spring summer and fall. The bees love it, it germinates beautifully, it provides awesome magnesium for the soil, and it grows soo quickly!

Finally expanded some of the garden and needed something to grow there quick. Did great. Looks good and the bees were very happy. Also broadcast around my tomatoes and peppers to help the ground from baking in the sun.
