Publisher's Synopsis
Excerpt from Seeding-Depth Trials With Bitterbrush (Purshia Tridentata) In Idaho: Research Paper 54; December 1957
Where bitterbrush seeds are planted singly, as they are in drill rows, a depth of inch probably is optimum for best emergente in the coarse sandy 10ams of certain southwestern Idaho game winter ranges. In some years frost damage may cause partial loss to seedlings coming from this depth, but the delay in emergence and the resultant protection from frost that can be obtained by seeding at greater depths will probably no more than compensate for the redue tion in number of emerged seedlings that accompanies an increase in depth.
