Abstract Urban agriculture has emerged as a practical strategy to strengthen local food systems in cities with limited land availability. Rooftop gardening, in particular, offers opportunities for fresh vegetable production, but the sustainability of this practice depends heavily on soil media preparation. This study evaluated the growth, physiology, and yield response of cherry tomato ( Solanum lycopersicum var. cerasiforme ) in different rooftop soil media supplemented with vermicompost and biochar. A 2‐year experiment was conducted during the winter season via a completely randomized design with four replications and nine treatments consisting of varying proportions of soil (74%–100%), vermicompost (10%–20%), and biochar (3%–6%). The results indicated that plant growth, physiology, and yield traits were significantly influenced by media composition. The combined application of vermicompost and biochar consistently outperformed the individual applications. The treatments with 74% soil, 20% vermicompost, and 6% biochar produced the tallest plants, the highest leaf number, thick stems, high soil plant analysis development values (leaf greenness), high relative water content, and the highest fruit yield across both years. Although fruit yield declined by 20.49% in the second year due to a reduced number of fruits per plant, residual amendment effects continued to enhance plant performance relative to the untreated soil. These findings demonstrate that integrating vermicompost and biochar into rooftop soil media improves soil health, plant physiology, and crop productivity. Such practices represent an effective strategy for sustainable rooftop farming and can contribute to resilient urban food systems in land‐constrained cities.
