Walnut 75g

More information

The Persian walnut, so named to indicate its place of origin, is the most popular walnut, grown in many parts of the world. It was used as a source of food on the ancient trade routes across Asia and so became established in China in the east and Europe in the west. From Europe, it spread westward to North and South America as well as Australia as the "New World" was unfolded. Persian walnuts will grow in a range of well drained soils from sand to clay loam. The pH should be between 6 and 7. They grow to 15 m tall and spread about 10 to 15 m as they mature. Grafted trees will begin to bear in 3-4 years while seedling trees can take 5 years or more. Generally, seedlings from good selections are productive, reasonably thin shelled and good quality, but to be sure of quality, filling, and production, the grafted tree is superior.
