The Clay Buster Seed Mix is formulated to establish wildflowers that grow excellent in heavy clay soils and are also highly preferred by pollinators. Planting this seed mix will boost local pollinator population and diversity while adapting to a wide variety of clay soils types in the Midwest, Northeast, and Southeastern U.S. This mix is also adapted to less clay heavy soils as well.

Clay adapted wildflowers dominate with a ratio of 90% wildflower seed to 10% grass seed. This design is to ensure long wildflower diversity long-term as native grasses and sedges can become over dominant over time when designed at higher seed proportions due to the lack of Bison and/or Elk grazing the Native Meadows/Prairies. The height is mixed with most plants remaining under 3.5 feet tall, and a minority of plants reaching higher than 3.5 feet tall. This seed mix is rated at 80 seeds per square foot and will bloom from May into October with a high diversity of native wildflowers. Its species will adapt to partial sun, full sun, seasonally saturated soils, moderate moisture soils, and lower moisture soils.

Cost Effectiveness

Native Prairie/Meadow Seedings cost about 1 to 11 cents per square foot where as using potted native plants to cover the same area costs $2.00 to $10.00 per square foot depending on how densely the potted plants are installed and mulch use. For example; a 1,000 Square foot pollinator garden would require at least 750 potted native wildflowers/grasses to cover the plot effectively. Potted Plants can cost $2 to $10 per plant, and at a cost of $5.00 per plant, 750 wildflowers/grasses would cost $3,750 + installation costs and mulching costs. If that 1,000 square feet were instead seeded with one of our mixes it would cost $107, and you could do the installation yourself simply: using our instruction manual. The cost effectiveness ratio increases even higher the larger of plot you are seeding vs. planting with plugs or potted plants - for 1/8th acre or larger the cost per square foot is only 2 cents where as the smaller 1,000 and 2,000 square foot portions are around 11 cents per square foot compared to the $3.75 per square foot cost of potted plants. Maintenance is easier and weed invasion resistance is much better with seeding projects vs. potted plant landscapes due to the density of native seedings repelling and blocking out weed competition as the plot matures.
