Water: Japanese torreya prefers humid subtropical climates and moist conditions, tolerating drought moderately. It's best watered deeply every 1-2 weeks. Typically grown outdoors, it thrives in well-draining soil that retains moisture during active growth while avoiding waterlogging.

Fertilize: For japanese torreya, use a balanced N-P-K fertilizer (e.g., 10-10-10) every two months during the growing season. Apply 1 cup per trunk inch, around the drip line. Reduce in fall and avoid winter feeding. Fertilize in the morning or post-rain, and always water afterward.

Pruning: Japanese torreya is an evergreen with dense foliage that benefits from winter pruning. Focus on removing dead branches and thinning crowded areas to enhance air circulation. Regular shaping maintains its form, while pruning in dormancy promotes health and prepares japanese torreya for vigorous spring growth.

Propagation: Japanese torreya is a slow-growing evergreen conifer that thrives in well-drained soils and partial shade. Freshly harvested seeds should be sown immediately for optimal germination without stratification. Consistent moisture is important, and young plants need protection from extreme temperatures. Germination takes several months.
