The rows of leaves on a tobacco plant. The number of primings varies, but six is average. The first priming is closest to the ground, the sixth is near the top. The higher the priming, the stronger the tobacco. Most fine cigar tobacco is harvested by priming. Workers always harvest from the bottom of the plant up, taking two to three leaves at a time. The lowest level of priming, known as sand leaf, or libre de pie, is often discarded. A few days go by between priming harvests, allowing the plant to further mature.
