Looking for Healthy Butternut Trees
Butternut trees (Juglans cinerea) are not common. Many people may have never tasted the nuts, which are prized in eastern N. America, where they are native. The tree is plagued by butternut canker, which has wiped out 80% of Juglans cinerea in some US states. To promote the tree researchers are searching the tree's native range for healthy stock to use in breeding research.
The Agricultural Research Service of the US Department of Agriculture has created a butternut orchard in Corvallis, Oregon as part of its germplasm repository. Scientists at the facility are trying to breed trees with larger tastier nuts as well as disease resistance. Researchers from the service will be touring several states this year in search of healthy trees.
Mike Ostry, a US Forest Service research plant pathologist has also been looking for healthy butternut trees. He feels that the best hope for the future of the tree is in finding trees that are naturally resistant to the canker.

Like some black walnuts, butternuts produce toxins that inhibit the growth of some plants in their vicinity. People interested in the tree may want to read more about this trait.

We are not conducting research on the butternut here at UBC, but the researchers mentioned in the article may be interested in receiving information about healthy butternut specimens.

How do you cultivate a tree from a butternut seed? I would like to grow seedlings from the tree I have in my yard.
Posted by: Donna at August 7, 2005 8:09 PM
Butternut seed should be sown fresh when fully ripe. It will need a period of cool stratification. You can plant seeds in deep pots and leave them outdoors over the winter. You will need to keep the pots protected from rodents or other pests that will dig out the seeds. It may be best to grow them in a cold frame. Germination should occur in the late winter or early spring. Alternately you could place the seeds seeled in a plastic bag with moist peat moss in the refrigerator over the winter and plant out in spring. Good Luck!

We have 5 butternut trees that have some dead limbs and are loosing leaves. What can be doon to help the trees?

I saw a huge butternut tree in the Atnarko River Valley above Stuie at the Robson place. It is huge and the only butternut tree I have ever seen. It was loaded with flowering parts in May of 2003.

I recenly found a butternut tree growing on my farm.I found it growing in a small secton of woods.IT all so has plenty of nuts.
This is the first butternut tree I have seen since I was small boy.By the way I live in southeastern OHIO.

we have a wonderful butternut here in Kinnelon, NJ. It is estimated to be over 100 years old. I have some of the dropped fruit. I would love to grow a couple of trees. Any suggestions would be helpful.

I found a very large and healthy looking butternut tree growing behind Clinton Memorial Hospital in Wilmington,Ohio bearing large elongated nuts.

We believe that we have a large butternut tree in our backyard in South Central Connecticut. It has bore fruit each year since we moved in 3 years ago. I have not seen any sign of canker. Can someone tell me what to do to the fruit to make it edible and cultivate more trees?

My father-in-law, a lifelong hunter and woodsman, had no idea what this tree was in my back yard (northern NH). Now I know why. Not very tall, but I have about 8 of them growing in a small cluster on one side of my farm.

Our tree was very much admired by my mother before she passed on, and when it bursts into leaf each spring I am reminded of her visits with us. We have trimmed the lower branches of the tree as they were overhanging the vegetable garden giving too much shade, but the main centre growth still spreads majestically 50 or 60 feet high.
My question to you is about the shedding of leaves - our tree constantly sheds leaves throughout the summer and is the first to be bare before the fall really gets underway. Is this normal? Our lawn is covered with leaves from the tree all season long.
Do you know if there is something we can do to prevent this loss of foliage?
Posted by: Ed and Stella Cox at September 21, 2005 6:59 AM
Ed and Stella, that sounds like a wonderful tree. I do not know the answer to the leaf drop. You may wish to ask your question on the UBC Botanical Garden Forums. The forums are set up for questions and you are likely to get answers there. Judging from the comments here, there is a lot of interest in the butternut tree. I would welcome discussion of the tree in the Fruit Tree category of the forums.
When I was growing up in Ohio, a butternut tree grew at the end of our lane. It was never vigorous and only attained a height of around 4 metres (12 feet), but it had the finest nuts I have ever tasted.

I have a large 35-40 year old butternut tree growing on the old home place. I has produced a bumper crop of nuts this year and shows no sign of canker. I have a neighbor and myself trying to get the seeds to sprout this year for transplanting seedlings in likely spots to try to replenish the tree (many locally are sick or dead) If anyone from a state or national government group would like some of the seed nuts contact me with the word butternut in the subject line and I will gladly ship nuts to you on a first come first serve basis.
The butternut tree is so useful and necessary to a healthy mixed forest it deserves preservation.

I live in northeastern Ohio near Canton and have a butternut tree in my yard with a crown that spreads 100'. It's limbs are long and reaching. It had a bumper crop this year after producing no nuts last year. I have no idea how old this magnificant tree is. I have lived here 25 years and it was huge and producing nuts then. The house is 140 years old, so I have no idea how long the tree has been here. It feeds many squirrels and always has ladybugs at it's base. Every spring we have volunteer sprouts of trees all over the yard. We also have another butternut tree about 250' from this one that is not as large or as big a producer but was here when I moved here.

How do I go about trying to start a new butternut tree?
Posted by: SAndra Abert at October 20, 2005 8:48 AM
I don't know much about the propagation of butternut trees, but apparently judging from Cathy's post above, they germinate naturally in their native environment with ease.
This would be an excellent conversation to take up on the UBC Botanical Garden Forums

I live in the Butternut Valley of upper New York State. I am looking to help the plight of butternut trees by offering a reputable research person, come and plant more trees and watch their progrees. I have lost all of my butternut trees with much sadness, and would like to replant and contribute to the future of healthy trees by finding out what we can do to make this happen.

I live in New York State,Approximately 30 miles from Vermont,right on the US.-Quebec border.I think that I have several large Butternut trees.I am having difficulty identifing the Butternut tree,I am almost sure that they are the same trees by what I have found in the pictures and info that I have gathered.Can you help me in any way to identify these trees.I have already made lumber from 1 very large tree and 1 small one that had died.I would appreciate any information that you could provide to help me with this.
Thank you----- ED

I live in Merrickville, Ontario Cananda
and have a healthy butternut tree in my yard.
What do I do with it?
Thanks Linda Hall

An Ohio Division Forester and I located two large Butternut trees in a secluded and rugged ravine in Southeastern Ohio. One has darker bark and appears to be healing over its cankers; no dead wood was detected. Is it possible that this is a naturally resistant speciman??? I will try to collect nuts and grow youngin's this year. Please contact me if this tree offers potential for your research and preservation work. Thank you.

I have just found a Butternut tree in our yard in Golden Valley MN. Please contact me as I would like to help to preserve the tree here in Minnesota. I believe the tree to be healthy, of course I can not be sure. Please help.

There is a large unspoiled forested area near Allegheny County Airport which must encompass over 1000 acres.
Scattered over this terrain there must be at least 100 butternut trees which look healthy to my eyes. When should the fruit start to appear?
Is it unusual to find this many butternut trees in so small an area?

Hello,
I am writting from Port Clinton, Ohio. We have a butternut tree in our backyard, in town, that has been there at least 50 years. The butternut crop is quite bountiful, but we'd like to know if there are any recipes for them and is there a special method to preparing them first. I don't believe it has the canker, but we will be checking that out this weekend. Thank you,
Lenore Jarmolowicz

I have a butternut tree planted it in 96. It did not produce any nuts until it was four years old. Then it took a couple years off and do not produce anything. After that there was maybe 6 nuts than this year. There was almost 100. Is it possible to graph the black walnut limb on to it? I read that the butternut is called the white walnut. How do you know, if they are ripe? Are there recipes you can use these nuts can be put in? I have seen some trees I believe what they did was made a slit in the tree and put some Pete Moss and burlap a round that slit and kept it moist until it rooted.(Do you know what I am talking about). Can you do this with any tree? By the way I live in West Virginia.

Living in southwestern PA., my brother has one each of black walnut, english walnut and butternut trees. The harvest was bountiful this year. Regarding recipes using butternuts, just use them as your only nut ingredient, or you can mix them with any other nuts, as my sister-in-law does (the butternut proportion is smaller as they are a richer nut).
I found with any nuts if you heat them in the oven, it brings out the natural flavor. Watch to not brown them much. Let them cool a little, chop if desired and add to other ingredients. The difference in taste is awesome. Blessings; jc4jc

Although it's been many years (1950s) since I visited my grandparents' farm, I will never forget the lovely Butternut Trees in their back yard (Hanover Ontario)! I remember sitting under the tree and cracking the nuts open with a rock (or hammer) as they are very hard and eating the fruit. So tasty and I've never had the opportunity to see a Butternut tree since then (have lived BC Lower Mainland many yrs). I was to read of its' extinction of course. Nobody has ever heard of them out west :-) and that is how I stumbled upon this forum. I wish I could help in some small way to fight off this disease that is destroying these lovely fruit-bearing trees. I wonder if they will grow in BC?

I read an article today in Nature Conservancy bulletin. It was about Butternut Trees. I have such fond memories of my grandfather and the butternut tree that grew next to my house in Frankton, Indiana. In the fall we would gather the butternuts and take them to the hay loft of his small barn. We would spread the current year's crop of nuts in a layer across the floor. The next spring the hulls would be brown and easy to remove. He had a special butternut cracker. It was an old clothes iron without the handle and a hammer with an old iron handle. We always used the same tools to crack the hard shell. Butternuts are about 2 inches long, and a scant inch wide. The outside of the nut is rough like a black walnut. The iron had a narrow groove where you could lay in to hit it and a rounded dent where you could stand it upright to whack it, if the other method didn't work. I own the iron and hammer and I think of Grandpa every time I see them. I haven't had a butternut in years, but I can still taste the butternut meat and remember my grandfather sharing them with me. I would love to try growing one here in Indiana. Does anyone have seedlings or a nut from which I could start a seedling?

I found two healthy butternut trees in our woods in S.E. Ohio, each about 40-60 feet tall. There are two diseased trees nearby one of them. I don't recall if the good ones had nuts but one of the "bad" ones did.
