Seeds per pound: 300,000 hulled
Minimum soil temperature for germination:
Soil pH range: 6.5 to 8.0
Planting Depth: ¼ to ½ inch
Planting Season: Scarified seed: Spring; unscarified seed: Fall
*Special considerations for spring germination: seed germination can be improved with mechanical scarification. Seed needs to be inoculated with Rhizobium for nitrogen fixation to occur. Germination of scarified seed generally occurs within 2 weeks after planting provided adequate soil moisture and temperature conditions are met.
