    Description

    For best results, direct-seeding of Douglas-fir in northern California should be done in November or December. In trials on two National Forests, sowing in those months resulted in significantly more seedlings than sowing in February or March. Also, more seedlings became established on fine-textured red soils than on coarser gray-brown soils. On red soils, more seedlings developed on south aspects; on gray-brown soils, more developed on north aspects. Some seeds particularly on spring sown plots-did not germinate until the second growing season.
