1. Clear Site Of All Debris

By mowing, cultivating, or burning. A chemical application (glyphosate) might help as well. You want to make sure your seed has as little competition as possible.

2. Prepare A Firm Seedbed

Make sure, after cultivating 4-6″ deep, that the ground is firmly packed with a harrow or packer-wheel. This insures that the seed will be sown at a consistent depth and that it will not dry out.

3. Buy Quality Seed

It is very important to make sure that you are using the best quality seed available. Good seed insures that you will not have a problem with the flowability through your planter or spreader, making for consistent seed coverage. When you buy Rivard’s seed products, your are guaranteed to get the highest quality seed available with unsurpassed vigor.

4. Plant Seed According To Specs

If you are drill-seeding, most natives require a seeding depth of no more than 1/3″ deep. If you are broadcasting, we recommend at least 1.5 times the drill rate. Both practices should be followed with a light harrow or packer-wheel. To be sure of seeding specifications, check with your local NRCS office.

5. Control Weeds

Mowing or spot spraying with a chemical application can reduce weed competition. We have seen the best results of native seed stands by mowing (6-8″) several times a year until established. Applying a chemical application will work, but most broad leaf grass chemicals will kill the forbs and wildflowers in your seed mix. The key is to mow before the weed heads seed out, and patience. A quality prairie may take between 2-4 years to establish, and you will see your planting develop into the prairie you envisioned.
