The present study was carried out in North-Western Coast of Egypt in summer resorts of Marina during the two seasons of 2012/2013 and 2013/2014 to study three maintenance systems (technical system, internal management system and specialized company system) on three ornamental plant species (Ficus retusa, Hibiscus rosa sinensis, and Vinca rosea) which were chosen in Marina resorts for evaluation, taking in consideration the effect of these maintenance systems throughout the four climatic seasons of the year on the tested plants. Evaluation of these factors included some plant growth and quality parameters such as plant height, crown diameter, stem diameter and plant performance. The results showed that among the three used maintenance systems, the specialized company system was the most effective followed by the internal management system, then the technical system which gave the lowest values in all investigated parameters. Moreover, the best results were measured in the summer season followed by spring.
