The count starts after Feb. 1st. To find the degree-days, add the positive differences between the daily high temperatures and 55° each day. When the total degree-days add up to about 300 degree-days is when we begin to see the pines releasing the pollen. When the total degree-days reach 626, pine pollen production has reached its peak.

Thank you for the explanation !
