Flowers that dry well are typically colorful, compact, strong-stemmed, and relatively low in moisture content. Harvest stems just as the first flowers reach maturity. Don't wait too long. Flowers at the top of the stem may be partially closed, but that's okay. Midmorning, after the dew has dried but well before any flowers wilt, is the best time to cut flowers for drying.
Dampness slows drying and can lead to mold.
When cutting, take as much stem as possible. This is the simplest and most popular way to preserve flowers. Cool, dry air is a requisite, so the first step is to choose a drying room. Low light is fine in the drying room, but direct light will drain the color from your flowers. Most flowers dry best hung upside down in bunches.
