Planting Guidance Chart for 35.724°N -78.683 °E
Based on Today's Date
Corn germination is based on an accumulation of at least 40-50 GDDs over the next 4-5 days (of the current date, not the planting date). This table shows the predicted accumulation of GDDs over the next 5 days, starting with each date.
| Mon | Tue | Wed | Thu | Fri | Sat | Sun |
|---|---|---|---|---|---|---|
| Apr 22 | Apr 23 | Apr 24 67 | Apr 25 80 | Apr 26 71 | Apr 27 73 | Apr 28 72 |
| Apr 29 69 | Apr 30 63 | May 1 83 | May 2 84 | May 3 69 | May 4 53 | May 5 35 |
Numbers in each box indicate the forecasted 5-day accumulated GDDs, starting on the given date. Daily GDDs are based on NWS Forecasts for days 0-7, and on historical averages for days 8+. 5-day accumulations shown may be based on a combination of NWS forecasts and historical data.
