Your fresh evergreen garland will begin the drying process as it is exposed to different elements of temperature and humidity. It will maintain its shape and style for years but the leaves will change in color to a lighter shade of green. Some shedding may occur. To prolong longevity keep out of direct light/sun moisture and away from direct heat drafts. Exterior use will also prolong the life. Expect fresh materials to be completely dried approx. days indoors and 14 days outdoors, weather dependent.
