How do I calculate my Accumulated GDD?

You can use our 'Growing Degree Days (GDD) Calculator' to find the GDD for each day. You need to sum the daily GDD values from your planting date to the current date to get the accumulated GDD.

Why are the growth stages different for each crop?

Different plants have different life cycles and respond to heat accumulation differently. The GDD thresholds for reaching stages like flowering or maturity are specific to each crop type.

What if my crop isn't listed?

This calculator uses data for common crops like corn, soybean, and wheat. For other crops, you would need to find a GDD chart specific to that plant from a university extension or agricultural service.
