Don gloves and cotton bag.
Start with the first cotton plant in the line. Assess the plant to see if the cotton bulb has fully bloomed. The cotton tuft will be fully exposed if the cotton is ready for picking.
Hold the base of the bulb with one hand. Loosen the cotton tuft gently from the bulb until it is removed in whole.
Move to each subsequent plant. Repeat Steps 2 and 3. Be careful not to remove cotton from bulbs that aren't fully bloomed.
