Yeah, it's like that in Indiana, too. I don't really remember when they get planted, though. I saw a lot of planting going on over the weekend. All I know is that it's got to be "knee high by the fourth of July."
Knee High was a really old standard no longer applicable. Modern franken corn simply needs to be planted by that date. However, work proceeds apace on development of varieties that can grow in Canada.
I just came back from a mini-vacation in Wisconsin the last 5 days, and let me tell you ..... I didn’t see very many farms along I-90, I-94 or I-43 planted yet. That’s not a good sign.
