All plants have an optimum range of temperatures for growth. While it may be obvious that temperatures too low will inhibit growth (if not damage the plant), temperatures that are too high can cause stress for the plant. Stress Degree Days (SDD) are a way of tracking how much stress a type of plant has been subjected to within its growing season. To learn more, see our "About Stress Degree Days" page.

SDD Departures are based on the 1991-2020 Climatological Normals.
