Black Walnut Tree Size and Roots
Expect a tree 50 to 75 feet high with a crown nearly as wide. The biggest on record, in Indiana, stood 150 feet. Rich soil can give a young tree 3 to 4 feet of new height a year. Roots go down before they go out. A one-year-old can already have a taproot over 4 feet long, and one 9-year-old Indiana tree had 7.5 feet of it. Hardy in zones 4 to 9. It wants sun, and full shade stops it.
Juglone: What Not to Plant Nearby
Leaves, roots and husks all carry juglone, a chemical that poisons some plants. Tomatoes, apples, blueberries, azaleas, peonies, birch and pines are on the list. It stays in the soil for years after a tree is cut down. A 2019 study questioned how far the effect reaches, but the safe move is to keep those plants well clear.
Nuts, Timber and the Wait
A walnut can set a few nuts at 4 to 6 years. Real crops take 20 to 30, and even then good years come about twice in five. Squirrels bury nuts and don't recover many of them, which is how walnuts spread. Timber takes longer still: 30 to 35 years for a 16 inch saw log, 40 to 50 for a 20 inch veneer log. Black walnuts live about 130 years.
Good to Know About Black Walnut
Wear gloves when you gather the nuts. The green husks leave a brown stain on hands and sidewalks. Keep black walnut wood out of horse bedding. Leaves open late, in early April in the south and as late as early June in cooler areas, and they turn bright yellow in fall. We ship black walnut to every state except Nebraska, California and Kansas.
Ordering Black Walnut Trees
Plant black walnut where it can stay. Deep, well-drained, near-neutral soil is best, and mature trees usually die after about 90 days of flooding. Keep the roots moist from the day the box arrives. Volume pricing is available on the larger packs. Our guides cover why black walnuts are worth the wait and which nut-bearing trees to grow, and you can browse more trees for sale.
