Building ridges in corn always seems to have a narrow window of opportunity. We had a couple false starts where we were burying too much corn. Waited 3 or 4 days and suddenly we were ridging like mad July 1 -3. A few areas in the field were already on the verge of being too large as my rock box occasionally snapped off a stalk because it is the lowest point on my tractor. That will be remedied before next year’s ridges are built.
One week later, the corn was significantly taller. No way we could have made it through it then. One mistimed rainfall and we may have missed our opportunity.
