The flower petals turn pink on the second day and later dry up and drop off and then form a boll. The cotton plant is constantly adding squares to the plant and then aborting squares or young bolls to balance out the demand of the growing boll load. Boll retention should begin near the level of square retention and show a gradual decline throughout the bloom period as the plant reaches its capacity for supplying bolls with carbohydrates.
