Black walnut is one of the most prolific trees in North America. They are highly prized for their timber, nuts and ecological value. Fine wood workers prize the wood for high valued wood products. The nuts are delicious and commonly used in baked goods. Black walnuts grow quickly and are adaptable to climates outside their native range. Our black walnut seedlings come from parent trees planted by famous nut breeder Jack Gellatly in Kelowna BC. 

Black walnut produces a compound called juglone which is toxic to some plants. While this affect is real it is often highly over emphasized and recent studies have shown that soil high in organic matter can help to buffer the effects of juglone. Basically don't plant it over your garden, research plants it doesn't go well with, and use several sources to make sure the information you have is correct. We have seen black walnut interplanted with many other types of food producing plants and trees with no problem whatsoever.

Nursery Practice: Direct seed to permanent site (risky due to likelihood of critter theft) or the preferred method is planting in air prune bed. Space seed at least 4 inches apart. Do not move live plant until dormant.

Planting Out: Seedlings can be field planted directly or after the 1st year in the home nursery once dormant. Be careful not to break the taproot when digging from the nursery bed.
