Wildflower Planting Instructions
Planting Date
Spring is generally the best time to plant wildflowers. Be sure to wait until the threat of freezing has passed. Late summer and early fall can also be a good time, especially where irrigation is limited.
Remove Preexisting Vegetation
Existing vegetation can be removed manually by hand pulling, hoeing, or tilling. If this isn’t possible, a broad-spectrum herbicide can be applied to the area 2-3 weeks before planting, after which the dead plant matter can be mowed, trimmed, or raked away.
Prepare the seedbed
After the site is clear of vegetation, till or rake to loosen the soil. Organic matter such as compost or grass clippings can also be added at this time to help with soil fertility, structure, and moisture retention (optional).
Spread The Seed
Sow the seed directly on top of the soil surface. A broadcast spreader is the most efficient way to do this. When seeding extremely small wildflower seeds, you can blend the seeds with sand for a more even distribution. A ratio of eight parts dry sand to one part seed is recommended.
Seed-To-Soil Contact
DO NOT bury the seeds as this is one of the most common reasons for wildflower seeding failure. Instead, lightly compress the seeds into the soil by stepping on them or by laying down a piece of plywood and walking on it. A roller can be used for larger areas.
Constant Moisture
Keep the area constantly moist during the germination period. Soil should remain damp, but not soaked, until the new seedlings are at least four inches tall.
