The heat and sun over the next few days will send a lot of corn to tassel and will help younger corn reach rapid growth. All of the corn that had looked pale and yellow during those storms will reach a deep green color by Monday, June 23, 2025, as long as it has adequate nutrients and good roots. Corn that was shin-high this week will be waist-high or taller next week. Corn that was shoulder high this week will tassel by next Friday.
By next Friday, June 27, 2025, we will learn if we have too many planting sins. Corn suffering from sidewall compaction, corn planted too shallow (or soil washed away), and corn limited by subsurface compaction will start showing nutrient deficiencies by the end of next week.
