Citrus fruit trees is a genus of citrus-like plants that prefer moderately sunny environments, well-draining, fertile soil, and consistent watering to maintain humidity without waterlogging. They generally favour warm climates. A common challenge includes citrus canker and pests like mites, aphids, and whiteflies. Specific care in summer includes protection from extreme heat and additional watering, while winter requires protection from frost. Changes in light, watering needs, and temperature tolerance throughout seasons should be observed.
