The ideal time to plant wildflowers is either in the spring (one month prior to date of last hard freeze) or late fall (after October).
For even distribution, combine with clean, dry sand at a ratio of 4:1 (sand to seed) and scatter by hand or mechanical spreader. Gently rake over the area covering to a depth of 1/8 to 1/4 inch or 2-3 times the seed diameter. Keep moist for 4-6 weeks to ensure the best germination.
Plant in open, well drained areas where seedlings will not be in competition with more vigorous species until firmly established.
