Seed Rate: 12 lbs/acre rate for broadcast planting 10 lbs/acre rate for drill planting
Ground Preparation: Ideal conditions for germination is seed planted at a depth no greater than 1/4 inch in continually moist soil. The best method for planting is direct seeding with drill equipment. Most soil conditions are conducive for drill planting without ground prep. Very heavy/clay soils may need to be worked up if drill is struggling to penetrate the soil surface.
If broadcast seeding is the only option then a fine seed bed is desirable since most of the seeds are very small (like alfalfa). If broadcasting into loose/sandy soil skipping ground prep may be acceptable. If working with heavy/clay soils first use a shallow (3-5 inches) disk or spring-tooth harrow to work up the soil, then plant seed with a broadcaster, then cultipack with a ring roller, which covers the seed by pushing it into the ground. Dragging a piece of chain-link fence behind an ATV or tractor can also be sufficient. The seed should be covered so it can remain moist.
Planting Methods: Use a grain drill, no till drill, broadcaster, or even a hand-held broadcaster on small areas to evenly distribute the seed Timing: After Sept. 10 through Nov. 10, while soil is still warm (above 55⁰) is an appropriate time to plant wildflowers in California. Plant no more than 1/8” deep.
Management: If reseeding is desired leaving plants intact until June or July may be necessary. This date will vary depending on planting date and local climate.
