Answer: Corn may be pregerminated indoors (wrap it in a damp paper towel, then wrap that in clear plastic and set it in a bright spot out of direct sun) and then planted directly outside to accelerate growth. (In general it is not a good idea to transplant corn.) The beans would be direct planted later when the soil is much warmer. This way the corn has a good head start over the beans and can gain some height before the beans need to climb. You may find too that the corn does better with some extra nitrogen, depending of course on the condition of your soil to start with. Good luck with your project!
