Seasonal Needle Drop (Horticulture/Urban IPM)
Description:

With the first snow falling, it is hard to believe that it is only fall. While the sun will hopefully come out again, conifers are still getting ready for winter. You may see yellowing and/or browning of the inner needles, especially on pine trees. This is a natural process called "seasonal needle drop". No management is necessary. For more information, please check out the attached PDF file.

Sincerely,

Eva Grimme (eva.grimme@montana.edu)
