Hi Jim,
A very reliable source of information for what to do during years 1 through 3 after seeding an area with wildflower seeds is Michigan Wildflower Farm.
Here is an excerpt from their website:
FIRST YEAR MANAGEMENT is critical for the success of your planting. Weeds will be a concern the first year. We recommend following a mowing regime for at least one-year post planting. Cut the planting to 4-6 inches whenever growth reaches 10-12 inches throughout the first growing season. A string trimmer works well on rough terrain or if mower cannot be set high enough. This technique is effective in preventing weeds from reseeding.
LONG TERM MANAGEMENT of a planting would include pulling weeds, cutting or spot spraying with herbicide. Do use extreme caution if spot herbiciding so as not to affect desirable plants. The entire planting can be mowed in late fall or early spring. If the site allows, burning every three years will help benefit a meadow planting. Do not burn the first two years, as tender seedlings may be damaged. Be sure to obtain a burning permit or contact a professional. In lieu of burning, a mowing/rake off every 2-3 years is beneficial to remove thatch buildup.
It is uncertain when the closing of operations at the Beltsville lab will occur, it could be as early as September 30, 2026 or phased in over years.
Anyone who has submitted or plans to submit samples to the lab should contact the USDA directly for current status of sample processing:
