Kwik-Krop Black Walnut Juglans nigra 'Kwik-Krop'

Phonetic Spelling
JOO-glanz NY-gruh
Description

Kwik-Krop black walnut tree is a cultivar of black walnut, a native tree species to North America. It grows rather fast when young but will slow down after it matures, preferring full sun and wet to dry loam or sandy high acidic to slightly alkaline soil.  Nut production can sometimes begin as early as 6 years but usually takes many years for a substantial crop.   It is cold and heat tolerant when established. The taproot contains juglone which might inhibit the growth of some plants such as azaleas, peonies, some vegetables like tomatoes, and blueberries beneath the tree's dripline.  Once used by Native Americans medicinally, it is a source for lumber used in furniture and veneer. This tree grows upright with a rounded crown.
