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.
