Reminders that autumn is close by are popping up around us. Stores are filled with school supplies and fall decorations. College students are preparing to return to their classes in a week or two. Fields of pumpkin vines are dotted with large orange fruit, ready to be picked. However, one of the surest signs of the change of season may not be so obvious. By the end of August the evening temperatures are dropping, making plant and lawn surfaces cool. As a result, the atmospheric moisture condenses on the surfaces below. We call this dew. The dew returns after a long hot summer to refresh the earth.
