Description
About the Stark® Kwik-Krop® Walnut Tree
The Stark® Kwik-Krop® Walnut Tree is an exceptional choice for growers who want earlier harvests and generous yields from a classic American black walnut. Selected for its ability to bear sooner than most walnut varieties, this grafted tree produces large crops of rich, flavorful nuts with thinner shells that crack easily and offer a higher kernel-to-nut ratio than typical black walnuts.
Kwik-Krop® is also a beautiful dual-purpose tree, providing cooling shade and strong landscape presence while delivering dependable nut production. The medium-sized nuts are easy to process and prized for baking, cooking, and fresh use. Harvest typically begins in early October.
This variety traces back to a native selection discovered in Kansas in the late 1920s and was later introduced by Stark Bro’s for its productivity, nut quality, and early bearing habit. The tree is self-pollinating, cold-hardy, heat-tolerant, and matures to 40–60 feet tall, making it well suited for larger properties and long-term plantings.
As with all black walnuts (Juglans nigra), Kwik-Krop® should be planted away from fruit trees to avoid juglone sensitivity and allow room for its mature canopy. With proper spacing and care, it rewards growers with decades of reliable harvests.
