Water: Originating from riverbanks, caucasian walnut prefers consistently moist soil but can tolerate moderate drought. Water every three weeks to ensure proper hydration. Its robust root system evolves from its native habitat's fluctuating water levels, supporting its resilience to varying moisture conditions.

Fertilize: Caucasian walnut thrives with balanced N-P-K fertilizers (10-10-10) applied annually in early spring at 1/2 pound per inch of trunk, focusing on the drip line. Reduce fertilization during active growth and avoid late-season application. Always water after fertilizing and use lighter doses for saplings.

Pruning: Prune caucasian walnut in early spring to encourage healthy growth and shape. Remove dead or diseased branches and thin overcrowded areas for better air circulation. Use clean, sharp tools to prevent infection and promote a vibrant, aesthetically pleasing structure for the growing season.

Propagation: Caucasian walnut propagation involves sowing healthy seeds in evenly moist, well-draining soil under shade to partial sun. Regular watering is essential for growth. Protect seedlings from extreme weather and pests to promote healthy establishment and growth of caucasian walnut.
