Product Details

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.

    This is my first experience with a covercrop. I started with buckwheat and, wow, it's amazing! I live in the southwest where ammending our mostly sandy soil is a never-ending chore. This is only 3 weeks of growth and it's already beginning to flower! I plan to cut it to the ground before it goes to seed, let the tops mulch in place, then plant my garlic there. I'm anxious to see what improvement it makes in my veg garden. Vetch and crimson clover are on my list next.

    Pollinator Paradise

    I am on the second planting as I am waiting to put in winter veggies here in AZ. The seeds sprouted quickly. The first planting was chopped into small pieces as a mulch/green manure and the second planting is getting ready to bloom. Pollinators love it!

    Hey Anna,

    Thank you so much for sharing your buckwheat success story! Two plantings, quick sprouting, and creating a pollinator paradise - you're really making the most of this versatile cover crop! It's so smart how you're using that first planting as mulch/green manure while timing everything perfectly for your winter veggie beds in Arizona.

    Your strategic approach to cover cropping will be so inspiring for other gardeners who want to maximize their growing space while supporting local pollinators and building better soil at the same time!

    Keep on growing 🌻️

    Buckwheat is so easy to grow, and my pet pig likes to graze on it.
