Unless you are creating a black walnut plantation out in the country specifically for the purpose of harvesting the trees' nuts and/or wood, I see no reason on this earth for planting one. They do NOT belong on the grounds of an ordinary urban or suburban house. A few observations:

The juglone contained in and secreted by every part of the black walnut--its roots, bark, branches, leaves, and nuts-- poisons the ground and everything living in it for at least fifty feet around it, so you won't be able to plant what you want, only the limited number of species that can tolerate juglone. Also, squirrels will bury the nuts in random places, spreading the poison even farther than the tree itself reaches. And even after the tree dies, the juglone remains in the ground for years bef... read more

It is a very common tree in my native northern Illinois and in the Mid-Atlantic Region and other parts of its large native range from the eastern Great Plains to the Atlantic, from south TX and northern FL to the southern Great Lakes Region in upland woods to bottomlands. It is a handsome, large tree with handsome dark furrowed bark and a strong outline. It bears lots of round walnuts that are good for wildlife and that can be processed to be edible for humans. It grows about 1 to 3 feet/year depending on how rich the soil is, which can be dry or draining wet, or acid or alkaline from pH 6.0 to 8.0. It lives about 150 to 250 years. It bears a large taproot and is hard to transplant. It is offered by some native nurseries in containers and by some nursery mail order magazines for the nuts,... read more

As a gardener, my feelings about this tree are mixed.

It's a very valuable timber tree. A single tree may be worth tens of thousands of dollars. People considering having a mature tree removed should be aware of the harvest value of their tree. The people you hire to remove it certainly are.

I find the squirrel-sown seedlings to be a weedy pain. They grow very quickly, and once well established regrow from the roots again and again, like ailanthus. I can get rid of them permanently only by digging down at least a foot and cutting there.

I've never cared for the strong flavor of the nuts, and it takes specialized equipment and a great deal of time if you want to extract the nutmeats in any quantity.

I have a mature black walnut in my front yard (about 40' tall, canopy is roughly 40' wide, and the trunk is about 2.5' thick). To be fair, it's a beautiful tree that provides our home with great morning and early afternoon shade. And its roots appear to be far down enough that the secreted juglone is not harming the two mature rhododendrons and three azaleas that have been growing under its canopy for years.

My problem with this tree is that it's very aggressively invasive. Because squirrels are constantly burying the walnuts in the late summer and fall, they're sprouting up all over the neighborhood. And they grow VERY quickly. If you have neighbors who aren't conscientious about what's growing in their yards, black walnuts will eventually become a problem. One sprout... read more

Good wildlife tree. A mature black walnut can tower to 100 feet, offering large limbs that serve as ideal roosting sites for wild turkeys and screech owls. Many species of woodpeckers, swallows, wrens, nuthatches and owls use black walnut cavities, and deer browse its leaves, twigs and buds. The nuts are a favorite of squirrels, rabbits and other rodents as it takes strong teeth and persistence to knaw through the hard shells. Woodpeckers also consume the nuts as do some ravens, who fly high in the air with walnuts in their beak then drop them to the ground to crack the shells. Wild turkeys will eat any pieces that remain after the squirrels have cracked them open.

I'm not going to give a negative feedback to this tree because there is plenty of information available as to what plants can be grown under it and I'm not stuck with an unwanted tree to deal with anyway. It's not for everyone and before planting, just educate yourself on it. Because of the falling twigs, limbs and nuts, the tree needs plenty of space and generally shouldn't be planted around a house. It pretty much has the same characteristics of a pecan tree, which is also messy in a home landscape. We have many old eastern black walnuts growing on the river banks and this year was a bumper crop. The trees make heavy crops in alternate years.

I planted and lost a lot of plants and trees before I realized that the walnut tree was the culprit. Most vegetable crops, fruit trees, and berry bushes will not tolerate being near a walnut tree.

People planting a large number of black walnuts should consider interplanting them with conifers. The author of Common Sense Forestry, Hans Morsbach, has planted thousands of black walnuts and found that they do better when they share space with conifers.

No one has mentioned the importance of eradicating weeds from the area where you plant a black walnut and controlling them for the first few years. I recommend (for small plantings) just breaking up the turf mechanically and then covering the area around the seedling with a 3' x 3' square of fabric mulch. Very effective in getting the tree off to a good start.

Pruning is another essential if you're raising black walnuts for future timber.

Plan on raised beds & will probably only remove the tree that is closest to their planned location.

We had a fairly "wet" summer this year (no drought) and I am woundering if this could explain the lack of set?

Unless you want them yourself for baking cookies do not be too hasty to pick them up. The squirels will do the whole job for you within a day or two. Such providence!

It is a beautiful tree which is easy to propagate by putting the nuts 1 to 2" in the ground. Squirels are natural propagators. One and two year old seedlings can be dug up and transplanted. A deep tap root makes it difficult after that. The wood is very desirable for woodworking, easy to work with power tools and hand tools. The grain is beautiful. In my 1/2 acre garden of 75' high trees there are trilium, jack in the pulpit, wild phlox and domestic phlox gone wild. The trilium and jack in the pulpit bloom in May, wild phlox bloom in June and the domestic phlox bloom July into September. All reseed themselves. They make a good companion planting and the toxicity of the black walnut keeps many competitors out.
