Our grafted English walnut varieties are proven superior for heavy and reliable production.
These stately trees have large compound leaves and a handsome branching pattern that makes them attractive, even in wintertime. The walnuts and butternuts will thrive in most of the nation.
Pollination: English walnuts are self-fertile but may produce at a younger age with a second variety for pollination. Plant two black walnut seedlings for pollination.
Sun or shade: Walnuts require full sun to crop effectively.
Plant spacing: 40 foot spacings are most commonly used as a permanent spacing for walnuts.
Harvest time: Walnuts drop from trees from late September to mid-October.
Bearing age: Seedlings will bear in six or more years, while our grafted trees will often bear in the second or third year following planting.
How to Grow
Soil requirements: For good production and long life, walnuts should be located in reasonably deep soils of good drainage. They prefer slightly acid to neutral soils.
Cultural requirements: After one growing season, apply a nitrogenous fertilizer mulch in early spring because walnuts like a steady supply of moisture in the growing season.
How to Use
In the landscape: Walnuts are a fine yard, shade, or street tree, though it should be a fairly large yard, and they should be sited at least 20 feet from buildings to protect foundations.
In the kitchen: Walnuts are a highly concentrated protein source and thus are a great snack item, and add a nutritious component to cookies, cake toppings, fruit pies, salads, and breads. Ground in a blender or chopped, they make a tasty addition to casseroles or a meatless nutloaf.
