Purpose: Problem-based learning (PBL), a relatively novel teaching and learning process in horticulture, was investigated. Proper application of PBL can potentially create a learning context that enhances student learning. Design/Methodology/Approach: Students worked on two complex ill-structured problems: (1) to produce fresh baby greens for a 4-week catering event and (2) to produce seedlings for a grower. Data collected were analyzed by the concurrent method and presented as case studies. Findings: Students developed positive attitudes through active engagement. Their presentations and reports demonstrated leadership roles, critical thinking and conflict management. Practical professional, social and affective skills were developed through production of 5 kg baby greens, and 2500 vegetable seedlings. Successes and limitations were identified. Theoretical Implication: The quality of the PBL problem is critical for the stimulation and elaboration of prior knowledge, development of epistemic curiosity and the relevant semantic framework. These are motivators that inspire effective learning. Practical Implication: Cognitive and emotional intelligence skills are realized by trusting the PBL process, identifying enhancers and inhibitors. Enhancement of creativity, social and employability skills manifest through challenges that help to develop for the "whole". Originality/Value: In the horticulture industry, stakeholders interact with each other and the agro-ecological system. Consequently, competencies in production and emotional intelligence are invaluable.
