Buckwheat has been used for centuries to improve soil health and smother common weeds. It grows better than most cover crops in poor soils and is better at retrieving phosphorus, a macro-nutrient that contributes to later crops' root, flower, and fruit growth. Buckwheat not only grows quickly, it also breaks down quickly in the soil, allowing for planting in the same area just 3 to 4 weeks after incorporating it into the soil. It can also be used as mulch on the soil surface. If allowed, white flowers will form about 35 days after sowing and are loved by beneficial insects and even make pretty filler in bouquets! Turn buckwheat into soil before seeds begin forming. Because buckwheat is cold sensitive, it is grown spring to fall frost, except in mild climates that may be warm enough to grow into fall and possibly winter.

I will plant it every year

5 out of 5 stars Oct 16, 2018
Early spring of 2018, we killed a bunch of the grass in the backyard by covering it with cardboard, and then covered that with compost. When the weather warmed up a bit, I planted buckwheat all over just help hold the soil in place while I decided what else I wanted to plant. As it warmed enough to put my tomato, pepper, okra and other starts out, I just dug a hole in the buckwheat and put my plants in. In places that the buckwheat got too tall and started shading my veggies, I just cut it down and left it in place on the surface of the soil. I let it flower everywhere else and the bees and other pollinators adored it. I had the best cherry tomato and okra crop I've ever had. It decays so quickly after it is cut, that it has already all incorporated into the soil and I didn't till it in anywhere. Just chopped and dropped. My neighbors were in awe of my garden this year and the number of pollinators that I had. I think the buckwheat definitely contributed to my success.

Yes! Did just what I planned. Mulched out buckwheat and mixed with potting soil for lettuce pots.

Buckwheat, peas & oats, mung bean sprouts

Planted Buckwheat and peas & oats in the fall. Didn't come up till the late spring. Will need to reread your instructions for this. Our climate is very different and crueler than most places that you sell this probably. It did come up and really competed with my melons. Liked it as a plant. Figured out that I should have left the roots from a gardener friend here. The bean sprouts are always good. My husband eats them and I put him in charge of all of that rinsing. Great project. Thanks for all that you guys do. Beautiful drawings on your packets. I am getting ready to try for a winter garden and hope I have better luck with some of the seed. There is a notch in the calendar where these will work straight in the ground. All our best!!!

Owner Response: Hi Debby, Thanks for the feedback. The buckwheat likely waited to germinate until the soil temperatures were best, which is different than it would be for peas and oats. We are always happy to help troubleshoot issues. Please don't hesitate to contact us! Happy gardening!

Good thing for the soil

I planted these seeds in a few areas in my garden - they were all in-ground soil in early January 2021. The seeds looked very healthy, and germinated really quick - they popped up everywhere. I ordered more packets - I think I got a dozen of them in multiple orders (along with other cover crops like Soil Builder Peas & Oats, Crimson Clover) and planted more. We (Austin, Texas) had a severe and rare winter storm in February which killed pretty much all of our plants, even huge & matured trees. Surprisingly most of these cover crops survived! I cut them down in spring and just integrated them into the soil before spring planting. Most of the new crops were thriving. I have to think these cover crops definitely helped with feeding the soil and the plants growing in it.

Works wonders

I love this cover crop so much! I sow them in place of where my early spring cold hardy vegetables were so that the soil will hold its integrity and to enrich the soil over summer so it will be ready for the next planting of cold hardy veggies that coming autumn. I definitely recommend letting this go to flower as it attracts such a wide range of beneficial insects. a big patch of it was growing beside my tomatoes last summer and i never had one pest problem on the tomatoes.

Owner Response: Hi Justin, Thank you for sharing your experience. We recommend killing this cover crop when 30% starts to flower to prevent reseeding. Happy gardening!
