Welcome to UD Cooperative Extension


In 1869, the University of Delaware (UD) College of Agriculture and Natural Resources was established as the state’s land-grant university with a mission consisting of three elements: teaching, research and “extension”.

Cooperative Extension fulfills the third part of this mission: bringing knowledge to the people of Delaware. Today, we offer university knowledge, research and resources — just for you! You have questions. We have expert answers.

From nutrition classes and Master Naturalist courses to 4-H youth clubs and programs that support local agriculture — UD Cooperative Extension has something for everyone.

  • Dreaming of a green Christmas

    December 14, 2020 | Written by Diane Stopyra
    When it comes to Christmas tree shopping, there is a lot to think about — and not just which kind smells the best (balsam fir), which kind offers excellent needle retention (Scotch pine) or which kind the family dog is least likely to, ahem, mark (a toss up).
