I was not able to find a publication by that exact title either. What type of clover do you want to grow?

Hello!

Unfortunately, we just have the one publication about clover seed weevil management (the second to last resource in my previous response).  I would be happy to answer any questions you have. Contact the Linn County Extension office<personal data hidden>) and ask for Christy Tanner.
