Nice job. What is the model number of that planter?
Hope you have better luck with your sunflowers than I did. I planted 3 acres a few years ago with a JD planter. They germinated great. Weed control chemicals worked great. Deer loved them. Cleaned out the whole field .
I used Spartan 4F at planting. I was trying to make a dove field, so total weed control wasn't necessary. You can mix Dual Magnum, Prowl or Pendimax for better grass control. The Spartan by itself did an adequate job for my situation.Hey TNhobbyfarmer what chemicals worked well for you?
