Acorn Sowing Date Affects Field Performance of Blue and Valley Oaks

Acorns of blue oak (Quercus douglasii Hook. & Arn.) and valley oak (Q. lobata Nee) were sown at monthly intervals from November until March. The earlier acorns were sown, the earlier seedlings emerged. First-year and second-year height growth and survival were also related to sowing date with the smallest growth and lowest survival for seedlings from the latest sowing. These results suggest that late acorn sowing reduces the chances for successful field establishment. Tree Planters' Notes 41(2): 6 -9 ; 1990.
