Question:
Black walnuts also exude a substance that is toxic to many plants, so don’t plant them near your garden. I think tomatoes and apples are affected…to be safe you might assume that no member of the rose family is going to achieve its fullest perfection near or withing the drip-line of a black walnut. — Live Globally, Die Locally.

I live in Northern California at about 200 ft elivation. There are lots of black walnuts here. They are hardy, in fact they are used to graft the English walnuts to. There are two things you should be aware of. First the nuts have a thick green cover on them when they are growing, and this cover is still on them when they drop. When they drop, they drop! They are heavy. They hurt! On tim roofs they are noisy! They are a little bigger than golf balls and just as heavy. Aslo this green skin will stain your hands. If you wanted to fake a sun tan, just rub the skin on your body and you will look like you had a heavy tan. I live around the old gold mines and there are still "stamp mills" for crushing the gold ore, so cracking the black walnuts pose no problems for me, as long as I don’t put more then three or four in the stamp mill at a time.

We have about 4 that grew on their own and all they contribute is squirrel food and opportunities for me to turn my ankle stepping on the fruit. The falling fruit is loud. On the drive it is a thump (after crashing through many branches). When it happens to fall on a vehicle, it has the wonderful metalic ring. They have even created some dents in our vehicles. My neighbor today referred to me as "anal retentive" for sweeping my drive with a broom. I, like my neighbor use a blower normally. But the black walnuts, especially when crushed, don’t collect with a blower. So, I swept my drive of my black walnuts. jl — JG Computing princeton!jonlab!jon 4455 Province Line Road Princeton, NJ 08540-4322 (609) 252-0159

Walnut tree exude a substance from the roots which is washed from their leaves by rain or sprinklers that kills plants and may be animals. We lost a rabbit very suddenly and we feel it may have nibbled on the fallen walnuts and/or its leaves. A friend had a dog die and there may be a connection. As a result we do not compost the leaves or leave the sticky green nuts on the ground. Admittedly, not all the flowers, shrubs etc around the tree are dying or dead but beware.
Walnuts and Pecan trees (and I believe Hickories too) produce a toxic substance called jugalone. This toxin is exudeed from all parts of the plants and can presist in the soil several years after removal. Jugalone acts as a inhibitor to other plants (its own "herbicide " if you will) . This effect is called alleopathy. Solanacous crops (peppers, potatoes and particularily tomatoes) can be killed by jugalone. This is known as Walnut Wilt. So for this matter it is NOT recommended that one uses debris from these trees for vegetable garden compost. Some Grasses are also susceptable. Most Dark wooded trees also produce tannins which can be toxic in large quantities. Oaks also. It is not likely that either of these substance would be in large enough quantities to kill a small mammal. However, I could not find a LD50 for jugalone. Gardeners beware! even roots from near by walnut trees can invade your garden. I know. This is why I know about these substances. They got my tomatoes one year.

When I was a kid, walnuts used to fall off our walnut tree and our dog would find them, crack them open, and eat the walnuts. He was always healthy and had no problems. However, one day, one of the walnuts got stuck in his throat. We were on vacation and when we came home, there was a walnut tree seedling in the middle of the yard with a dog collar around it. —Steve

We had a rabbit that would frequently eat walnut leaves and sticks with no apparent ill effects. (Until it died quite suddenly, not from poisoning, but from being eaten by a dog whose owners let run loose.) We never had to worry about leaving the nuts on the ground because the squirrels took them away quite rapidly. — Steve Mercer

My dad just gave me two little black walnut trees (which I’ve planted in the backyard) and a bushel of black walnuts. I left the bushel out on my porch & the squirrels attacked it. They had a little trouble getting the nutmeats out of the very hard shells (I cracked them open with a heavy hammer), but they sure seemed to be enjoying what they did get. I was even thinking about taking the bushel of nuts to the woods & leaving it there for the animals. Before you leave it in the woods, care to send me some? I love black walnuts and often use them as a treat in baking. Will pay postage. Louise

I don’t know what to make of your animals dying. I’d sure hate to give the black walnuts to the animals as a treat & have it kill them.
Having grown up in Eastern Kansas where Black Walnuts and bunnies are quite common (i.e., native), I find it very biologically unlikely that they would be harmful to wild rabbits. If they were indeed toxic, I would expect that the rabbits would have evolved to avoid them. There is an alkaloid in the hulls that is toxic to fish: Plains tribes of Native Americans crushed the hull and put them in streams to stun the fish so that they could be collected. I might further add that I have grown quite nice vegetable gardens very close to large black walnut trees without any problem, despite what I have heard to the contrary. (I must admit to holding a prejudice in favor of the black walnut tree— for its exotically flavored nuts, its fine hardwood, its beauty, and as the structural support for my favorite swing in childhood.) — Mike Lacy, Sociology Dept. voice (303) 491-6721 Colo.

Back in the late 1970’s, there was a book about growing and farming black walnut trees for profit. After 15-30 years, you could sell the trees to furniture veneer makers and get 5000-15000 per tree (I’m sure it’s more now). You plant 200 trees and you’re a millionaire when you retire. Anyway, this book listed a small company that produced black walnut tree seedlings that were bred genetically so they grew straight and didn’t fork. It cost $3 per one year seedling…(1978 price). So, as long as it’s a first year seedling, you should have no trouble transplanting it successfully. My grandfater grew English walnut trees from seed that the squirrels planted for him. He gave us a year old seedling, we transplanted it, and it grew into an enormous and healthy tree. —Steve

I’m not sure what zone you are in and I don’t know the exact range of Walnuts but I’m looking at a Stark Bro. Nursery Book and the general range they recommend is zone 4-9 depending on the type of walnut you choose. I have had decent luck getting seedlings to live by planting walnuts in the fall and they will (some of them) germinate and produce a tree..No guarantee on quality of nut due to genetic roll of the dice. The tap root is very important as pointed out in the previous post. We have a silty loam soil type here with 12-15" of topsoil and lot’s of walnuts growing wild. I’m not sure there is any special preparations that have to be undertaken but don’t be disappointed if transplants don’t do well. The younger the transplant the better. Good Luck Tim

I need information on the care and nuturing of what I believe is a black walnut. I am obtaining a couple saplings from the family farm, but I am not sure if the soil where I live (significantly far away) is conducive to the growth of Black walnuts or what I should do to ensure the young tree gets off to a good start. Anything I can find out now will help me prepare the soil for the spring planting.
Maybe someone can correct me, but I think a black walnut is a tap rooted tree, and if so very difficult to transplant. The length of the tap root will be similar to the height of the tree so almost impossible to dig up intact. If cut it will take years to regenerate and the tree will not prosper until it does. This is why one rarely sees pecan, hickory, walnut, some oaks, etc. in nurseries: Tap roots arn’t compatible with pots either. They do make for some very nice trees however. — Lloyd Fortney —Opinions, just opinions—
