A system to collect information about plants on a per plant or near per plant basis and to promulgate remedial courses of action is disclosed. A horticultural operation collects plant information, aggregates the information, and allows an administrative worker such as a master grower to review issues about plants in a grow operations and the associated potential remedial course of action. The administrative worker can then browse data about the affected plants to determine whether to select the potential remedial course of action. Browsing and review of issues may be done collaboratively by remote administrative workers. Remedial courses of action are then dispatched to line workers solely using an iconographic language, who in turn provide notifications when the courses of action are done. Administrative workers may then validate and verify that the courses of action have been properly executed and evaluate the courses of action's efficacy.
