How to grow black walnut

When to plant black walnut

NC State Extension says black walnut has a very deep taproot that makes it difficult to transplant, so it is best established young. It gives no planting date; set out dormant bare-root stock in early spring while the soil is workable.

Black Walnut is timed by season rather than your frost dates, so the planting calendar does not generate ZIP-specific dates for it. Check the cited sources below to fine-tune for your area.
