In its native habitat, cotton is a perennial that does not die in the fall. During periods of drought, the most mature cotton bolls continue to develop and less mature bolls abscise. Cotton's indeterminant fruiting habit derives from its perennial nature. In North Carolina, cotton blooms for up to eight weeks. True leaves appear 7-10 days after the cotyledons appear. Flower buds appear on a fruiting branch, which arises from the axil of the fifth to seventh true leaf, after 30-35 days of vegetative growth. Approximately 90 percent of the harvestable bolls appear at the first or second position on a fruiting branch. Excessive nitrogen applications may delay fruiting. Plant mapping techniques determine fruit retention. Fields with low early square retention respond to applications of Pix. Plant monitoring during the boll opening period helps schedule defoliant and boll opener applications.
