The California black walnut thrives in direct bright light and prefers moderate temperatures. It requires a period of dormancy during the winter. Regular watering is needed, but the soil should be allowed to dry out almost completely between waterings. Moderate humidity levels are ideal.محصول
Juglans californica, commonly known as the California black walnut, is typically harvested for its nuts and wood. The nuts are usually ready for harvest in the fall, around September to November, when the husks begin to split and the nuts fall to the ground. To harvest, gather the fallen nuts and remove the husks. The wood, being a hardwood, is often harvested during the tree's dormant season in late winter to early spring to minimize sap loss and ensure better wood quality. Proper care should be taken to avoid damaging the tree during the harvest process.تربة
