Orchid plants are one of the most popular floral decorative plants. Among the several species of orchids, Phalaenopsis sp. is popular because of its distinctive color, shape, and size. However, orchids have a slow growth rate due to their long juvenile phase; thus, culture technique modification is required to boost their growth, i.e., shading and fertilizer application. This research was carried out to obtain the best shade percentage and fertilizer concentration to increase the growth of Phalaenopsis sp. The experiment was conducted from June to December 2022 at the greenhouse of Bale Tatanan Padjadjaran, Faculty of Agriculture, Universitas Padjadjaran, Jatinangor, Sumedang, Jawa Barat. The experiment used a split-plot design of eight shade and fertilizer treatments. The plants were cultivated in two shading intensities, namely 60% and 70%, then treated with four different complete foliar fertilizer compound concentrations (1, 2, 3, and 4 g/L). The results showed that 60% shade and 2 g/L fertilizer concentration significantly affected leaf length and root length, whereas 70% shade and 4 g/L fertilizer concentration significantly affected leaf area, chlorophyll content, and root number of Phalaenopsis sp.
