I AM DESPERATELY SEEKING TO PURCHASE BLACK WALNUTS JUST FALLEN OR ABOUT TO FALL! THIS IS A POWERFULL HEALING AGENT ERGENTLY NEEDED, FROM ANY WHERE IN NZ PLEASE CONTACT ON 09 424 3669 OR EMAIL amber.mcgregor@yahoo.co.nz THANKYOU
Hi Amber, I’ve got a tree full and want to pass them along. Problem is that i am in North Canterbury.
Any thoughts or anybody local interested

Please could anyone help. Last walnut crop most of the walnut shells had holes. What would be the cause? Would it be an insect? or perhaps the lack of nutrient / s? And what would be the solution?
Hi
I have a 60-70 year old Walnut tree on my Wairarapa property which recently lost a major limb (almost half the tree). The remainder of the tree is still standing but I think may have some rot.
I’ve had a arborist take a look and he suggests felling the remainder. I’m very reluctant to do that as I really love the tree however it is close to the house. Is there anything the arborist is ‘nt telling me in regard saving the tree ? Should I get a second opinion ?
It’s not a particularly straight tree but if it does need to come down is there a market for the wood?

Hi I would very much like to buy a small quantity of green walnuts off someone when the time is ripe. If anyone would like to sell a couple of bags please contact me on jloc@woosh.co.nz (I am in the auckland area) Many thanks, Janet
Hi – wonder if anyone has had experience with a walnut tree releasing water from its cut roots? We’ve just put in a driveway past a 20-year-old tree, it’s reasonably healthy, sometimes has blight, other times not, we just leave her to it. Flat, sandy soil, in Waikato, within 500m of natural waterways. Have ruled out all other sources for an amount of water which seems to be rising from the driveway, in the exact spot that a few roots were cut to make room. Someone raised a theory it could be the tree. “That’s Impossible”?
Where can I buy Franket Walnut Trees?
I am wondering if you can help me, or refer me to someone who can.
I have a large black walnut tree (Juglans nigra) overhanging our newly built house. Our water supply for the house is from the water catchment from the roof, collected into a water tank.
As you may know, Black Walnut Trees product a natural toxin called Juglone.
I have concerns about the safety of our drinking water, after reading about the toxic effects of juglone on dogs, horses and plants.
The water tank is not currently connected to the house, as we are still in the building stages, however I am hesitant to get it connected until I can determine if juglone which is found in the roots, leaves, hulls and fruits of the tree can seep into the water and contaminate it.
It would be a costly process, once the water supply is connected, to discover if the water was indeed tainted, and therefore could not be consumed.
We may need to have the tree removed (it is a protected tree), so I want advice as to if this will be necessary, and information to provide to our local council.
Any help you can provide me with would be appreciated.
Kind Regards
Johnna Alborn
Hi Johnna,
I am no expert but would suggest that any roof water should be filtered anyway, because of bird sh***t , a real health hazard.
I suggest you talk to a good filter supplier or reputable plumber.

Hi Joanna ,
Black Walnut wood is very valuable up to $80,000 per mature tree, Make sure you have it milled by and expert.
Perhaps you could persuade the council to let in come down in exchange for some money going towards a community project ;.)
Also do you have any seedlings ? thanks
Hi. I have a very large old tree that is perhaps 60 years old on the property that we purchased last year in Taupo. The tree was unloved and growing amongst a lot of debris and native undergrowth on a section that we have since built on. It produced a good crop of walnuts last year (although small). This year the section has undergone development, clearing and irrigation. The tree has grown considerably and the walnuts were huge (almost apple size!) when green. I was very excited about my pending crop. As the fruit has ripened it has developed a black mottle and some have large areas of black almost rotten looking patches. The fruit inside is very damp and black/mouldy. The rest of the tree (foliage wise) looks very healthy. I am really disappointed and after searching the internet I am unsure what the problem is. Does this sound like blight and how can I start to tackle this problem with such a huge tree? We have had a very long, warm humid summer and wet spring this year in Taupo and I wonder if this is just a seasonal problem or if it is more serious? I also have mulched around the base of the tree with compost and it has been irrigated frequently (Am I killing it with kindness – affecting the PH levels??) Please any more information you can provide me with about possible causes or indicators to look for which will tell me what I am dealing with would be greatly appreciated!!
Many Thanks
Sherri
Hi Sherri
This does sound like walnut blight, and you are correct that blight is much worse in humid conditions. There is quite a bit of info on walnut blight on the NZWIG website (e.g., see the Research section, including http://www.walnuts.org.nz/reports/sprayguide.html )
Normally in commercial orchards we use copper sprays in spring/early summer (particularly at budburst time) to control blight. However I can understand it would be very difficult to achieve spray coverage on a single large tree like yours.
There are not a lot of other options for controlling blight apart from copper sraying, so you may just need to accept that your crop will be more or less affected depending on the dampness of the particular season.
Anything you can do to assist the drying of the tree after dew and rainfall could help (e.g. by allowing breeze through the tree / not having it excessivey overgrown by shelterbelts), since the blight bacteria spreads and infects via water droplets on the leaf and nut surfaces. Also it could well be worth removing the mulch and irrigating less, as this could help keep the overall environment round and inside the tree drier – I don’t know how wet you have been keeping the soil but in general it’s better to err toward the slightly dry side rather than the wet side with walnuts (they don’t like wet feet) – though without going to the extreme of allowing the tree to turn yellow and lose its leaves with drought! I suspect that a large old tree is probably able to fend for itself in your climate without irrigation, though I don’t know your summer rainfall figures so may be wrong.
Cheers, Heather
Its Feb 2011 and there are a lot of walnuts about on my property, which is situated near CHCH. Unfortunately at least 25% of my crop has fallen off or ready to fall off. This is due to the nut going soft and mushy. The outer husk starts turning brown , sometimes all of it , sometimes just half of it. When the shell is opened the walnut is a mushroom colour and in various states of mushiness.
Does anyone know the cause of this, what it is and how to prevent it for next year ?
Hi Tony
That sure sounds like our old enemy walnut blight to me. I will be interested to see if others come up with an alternative diagnosis. Good old xanthemonas juglans I reckon.
Graeme
Hello Tony
I’ve just had a chat to Clive Marsh about this, as we have seen nuts with these symptoms in Tasmania, and also occasionally in NZ. The symptoms you have described sound like Brown Apical Necrosis (BAN) which is a fungal disease. We’ve had quite a bit of warm, damp weather this year – perfect conditions for fungal development.
Clive pointed out the following scientific paper which discusses BAN:
http://apsjournals.apsnet.org/doi/pdf/10.1094/PDIS.2002.86.6.599
Apparently BAN often seems to occur on the same nuts that are also infected by walnut blight. Did you observe very much blight on the nuts in mid-January?
In any case, if you are applying a series of copper sprays for walnut blight (usually from budburst until around Christmas), then I would expect this to also provide some control for a fungal disease such as BAN. What was your spray programme this season?
Cheers, Heather
Thanks for your reply Heather.
Sure looks & sounds like BAN.
I did have a bit of blight, especially on the 157. Rex showed minimal blight, but have taken a hammering with this disease.
A couple of trees (the ones that are meant to be Rex ,have lost the complete crop).
Funnily enough Myric are not too bad with blight or BAN.
I only sprayed 2 or three times at bud burst and 3-4 weeks later, but not a lot on Rex as they had proved to be more blight resistant than the others.
I have been spay irrigating 3 times a week for the last two months – this probably didn’t help.

Can anyone out there in walnutland give me some ideas on the best way to manage clover growth in the understory
Does mowing back hard reduce the potential nitrogen gain,or should it be left to get ankle high.-Does clover that has been cut back come back more strongly than it would have otherwise.Does the mowing of top growth encourage more root growth,hence more nitrogen fixing,or does it mean less flowering /seeding,and relatively less clover the following year.To what extent does the fixed nitrogen become available to the walnut trees,hence reducing the need for urea,or is healthy clover just a sign of a low nitrogen soil.
Any musings welcome. Linton
Hi all,
I was looking at some land in Waihi, BOP. I was going to grow chestnuts but have been warned away from this crop.
How do walnuts do in Waihi. The property i am looking at has shelter belt, north facing, was a kiwi fruit block with all the vines pulled out.
Your thoughts would be appreciated as I do not know what I am doing and getting into.
Thanks,
Peter
Hi there, I got a land of 51 Ha in Coramandel I want to plant black walnut trees. the land is gental slop , now full of manuka bush.
is that suit walnut? where can I got the seedling?
Hi Mike
Interesting enquiry. As an industry group we are not really expert in black walnuts, although some of our members may be and may like to comment. The industry is really based around supporting growers of juglans regia – or the Persian Walnut, for nut crop. Most of these orchards are not planted with seedlings, but with grafted trees so we can control the quality of nuts. From the little I know about black walnuts they are rather prone to wind damage, so thinking about the wind on your site will be important.
Best wishes with your exploration.
Graeme
I’ve had an enquiry from Martin Otero, a walnut grower in Chile. He would like to do an internship in New Zealand and ‘share knowedge and experience’ for three months.
He is applying for a grant from the Chilean government which would cover 70 per cent of his costs. He would need the New Zealand grower to cover the balance.
At this stage it seems likely that he would come to us in November.
Let me know if you are interested in exploring the possibility of having him do his internship at your orchard or maybe sharing him amongst growers in your area.

We have recently bought a property just north of Wellington with 5 walnuts trees (House built 1915 and trees look this age too).
Just one of the trees has been dropping loads of green walnuts since mid Jan. Can these be dried out and eaten, or do I have to wait until the black ones fall?
Any idea why this one tree could be shedding early?
I would be interested in having someone check the wellbeing of our trees, to assess if they need any pruning, although I hear a good gust of wind will usually get rid of any unnecessary wood.
I spoke to a guy in Palmerston North who has a plantation of walnuts at Ashhurst, just out of almy, and he says last year he had a bumper crop, this year he has none, and simply puts it down to a poor season. So maybe you don’t have to be too concerned.
Where can I purchase green, soft, walnuts. I live in Palmerston North

Hi Mike
Perhaps without seeing the tree, I should not comment, but unfortunately your ‘conspiracy theory’ does sound rather plausible. I have seen a situation where a grower mistakenly left traces of moss killer he had used in his backpack sprayer, and then used the backpack to spray his trees with copper (for walnut blight control). The trees were extremely late to leaf out in spring and then had very few leaves (the grass underneath also copped some run-off and turned up its toes). I think in the end the trees did recover though I have not seen them recently. However, if you do think there is a chance it could be an exotic disease, it could be worth a call to MAF’s Exotic Pest and Disease Hotline 0800-809-966, as they would be best placed to suggest how to proceed.
Cheers, Heather
Hello Heather
We live in Christchurch and have done at the same address for nearly 32 years. The tree was well established when we arrived – hence my guess at being 50 years old. Except for the last 2-3 years we have always had a bountiful supply of walnuts. Then over the last 3 years it started to progressively have fewer leaves with each spring and the crop correspondingly dropped and we had virtually no walnuts last year and certainly none this year. A few of the branches seem to be struggling to produce a few leaves this year but otherwise the tree looks bare with perhaps 90% of the branches appearing to be dead. There is no obvious yellowing of the leaves that are there. There is a yellowish moss/lichen type growth on the bark – covers about 50% or so of the existing bark surface – but this is not new and has been there as long as I can remember. Nothing else has changed in the environment except for the renovation of an old (110 years) neighbour house through a succession of occupants over the last 5 years. Successive owners chopped down virtually all the old well established trees on that property – the leaf fall into the new swimming pool is probably the reason for this! It just so happens that our walnut does/did shadow their garden near the pool – conspiracy theories abound over possible previous (not the present!) owners actions???
The only other comment I can add is that our other neighbours who also border the ones just talked about have mysteriously had their well established Holly Oak (an evergreen!) lose its leaves – it is not quite as sick as our walnut. It also throws a shadow over the said other neighbour??
Query posted on behalf of Mike Dewe:
I am looking for someone who is knowledgeable on walnut tree diseases to advise us on a 50 year old walnut tree in our Holly Road garden that has been progressively dying over the last 3 years. This year there are very few leaves on the tree and I suspect that it will have to be removed but would like advice before removing what was a very healthy tree.
On the web I picked up the problem that is now rampant in black walnut trees in the USA ā a disease related to the Geosmithia genus (the so called Thousand Canker Disease) which is apparently killing hundreds of walnut trees in California and several other states within USA. It has been likened to Dutch Elm Disease and its devastating effects. It is apparently transmitted by a small beetle and has only become known about in New Mexico in 2001 ā so it is relatively new. The symptoms on our tree are very similar so we were wondering whether it has crossed the Pacific and hit New Zealand.
I would be very grateful for any help. If it is in any way related to the USA problem then I think NZ is on the brink of inheriting a similar problem.
Thanks

Thanks for this enquiry. We are not aware of Geosmithia in NZ so it would be very concerning if you have discovered it. As an industry research group we would like to know more and have it checked out.
Graeme
Hello Mike
It’s hard to suggest a diagnosis without seeing the tree and the environment it’s growing in. Are the symptoms a gradual yellowing and loss of leaves? Are there any other symptoms (e.g. have you seen any cankers on the trunk?). Normally if we saw a tree in an orchard with gradual yellowing and loss of leaves (assuming the tree is not in drought stress) we would be suspecting phytophthora root rot, which is brought about by the roots being too wet, and is not uncommon in NZ. Is there a chance there could be standing water under the tree within a few metres of the surface? Where in the country are you based? I certainly hope the disease is something we already have here, but if not, it would be important to quickly get a sample sent away to a MAF diagnostic lab.
Regards, Heather
Hi, We have recently purchased a property in Rotorua and have discovered that there are about 20 white walnut trees which are just starting to fruit. Does anyone know of a market for these walnuts. The outer flesh is quite thick and yellow and dosn’t fall off the walnuts, unlike the other varieties that are also on the property.
Thanks
Oops forgot to say where we are…..Eastern BOP.

Hi. I was wondering if someone out there can help me. We purchased a block of 13 acres a few years ago and on it is approx 15 large walnut trees. When we purchased we were told that it was thought that they were Black Walnuts. These trees each year produce a large quantity of walnuts which go to waste as my understanding is, that you can not eat Black Walnuts (despite the fact that one year a local Maori asked to have some and the rabbits enjoy a good feed).
My question is this….how can I tell if these trees are Black Walnut, without cutting down, and if they are…what can I do with all the nuts?
Hope someone can help me. Thanks.
If anyone out there is in need of an excellent hand held nut cracker, we have recently designed and built the WonderCracker. It can easily crack hazels, macadamias, pecans, or walnuts, (except the bigger grafted varieties). These crackers are not available from retail outlets, only direct from us here in the Bay of Plenty. Check them out!
Cheers,
Paul Robin, Ohiwa Macadamias.
Hello,

Can you advise me on which variety of walnut to buy for growing in the Whangarei area/ Northland? and any key differences between the different types?
Hello
We have a two year old walnut tree that we planted on our property in Kerikeri. It seems to be a healthy specimen and has produced good growth in the second year. It is a grafted variety labelled as ‘ Walnut 1340′. Is anyone able to provide me with information on this variety as I have been unable to find any.
Many thanks
Craig.
I am in Dunedin and have one large walnut tree. There are a lot of walnuts on it this year and a lot have fallen off already. Is this too early? Are they all right to keep and would I have to take the green husks off them first? The husks are not at the stage of splitting themselves. Thanks.

Hi Jim
Thanks for your email on the availability of Paradox seed. It’s not easy to get hold of in NZ, but we are currently trialling a few trees grafted onto Paradox (seed taken from a hindsii tree surrounded by regia here in NZ) to see how they go compared to our standard regia-rooted trees.
I just thought I should mention, though, that we have very stringent biosecurity regulations here in NZ, and any walnut seed we want to bring in from other countries would have to go through Level 3 quarantine and be thoroughly tested for pests and diseases (eg. we don’t have walnut husk fly here, and would not like to get it!) – it’s slow and expensive to go through this process. The regulations are at:
http://www.biosecurity.govt.nz/files/imports/plants/standards/155-02-05.pdf
It’s unfortunate, but it would be quite difficult for us to bring in Paradox seed.
Cheers, Heather
I found this site – as I too – like Brigid would like to find some green walnuts.
We had two huge trees in South Canterbury and my mother always pickled them. Quite a job – I seem to recall pricking them with a (silver?!) fork.
Also at some point during the year I used to go out and hit the trees once with a hammer on the trunk – to ‘wake’ them after winter!
I live in Nelson and would look forward to any pointers/ideas.
Happy NY – Jj

It would helpful to know what part of the world you are in. I am not aware of such a stem grub, although others may know more.

We had a huge beautiful Black Walnut Tree but sadly it’s not so beautiful anymore.Last year two huge branches died.The leaves rapidly wilted,died and dropped off.I had them chopped off ,but now another branch is dying.
They’re all on the same side of the tree which is on a slope and the dying side is at the bottom.
I looked on the web and wonder if its phytothora?
What do you think? Is there anything we can do to save it?
The dying part has oozing black bark which starts on the large limb (where all the dead branches come off)rather than the main trunk.Should we cut the whole large limb off? Also ,like Graham before me (#18) the dead branches had grubs eating it.(The arborist I got to cut off the branches said the grubs come after the tree is sick rather than being the cause of the dying branch.He didn’t know how to help me though and didn’t know why our tree is dying.)
I have a mature walnut tree which fruted last year. This year a grub has got into the stem. Most of the branch tips have died and therefore has not produced any leaves or fruit. I cannot find anything on the web about Walnut stem grubs. I have several types of fruit trees on my porperty. Does anyone have any advise to share on my dieing tree.
Many thanks

Has anyone bought a machine like the ROTO-NUT on this American website and where did you get if from?

Most growers around Canterbury are selling their nuts to A Cracker of a Nut, in West Melton. they also buy nuts from old trees such as yours. You can find out more on http://www.crackernut.co.nz
It is important though to gather the nuts and spread them out to dry so they keep their quality.

We have a very large lovely old walnut tree that has and still is dropping hundreds of walnuts and I don’t know what to do with them all as we will never eat them and hate to see them go to waste. Any ideas we live in mid canterbury
I have a very large, old walnut tree which is producing plenty of fantastic walnuts and am having trouble as to how to dry them out effectively, due to the cold wet weather. I am finding that each year alot are not drying out to great and some are mouldy inside. There are far to many walnuts for me to spread them out in garage. Have been puting them in baskets and in plastic kids pool shell. Would they dry out better if hang in onion bags in garage?
Would appreciate some expert advice on this.
I am in Christchurch. I found where I can buy wulnut trees.
Kate
I hope others will also respond. My observation is that most growers simply leave it to gravity and nature. Some use a rake or other implement to shake individual branches.
Graeme
We have a walnut orchard of about 400 trees. Many of our trees are now too stout to be shaken by hand. Do any growers have a mechanical tree shaker- we would love to see one if possible!
Cheers,
Kate

You need to have the nut out of the green husk to dry. Ideally the husk has split and allowed the nut to fall out.

I like wulnut. I do not where I can a some wulnut trees.

Many thanks for your prompt reply. Do I leave them to dry with the green outer covering still on or remove that first ?
My only experience of walnuts has been the cheats way of purchasing them, ready to crack open, to make christmas a real cracker. !! I take on board your comments about the correct time to attempt to improve the shape of my tree, but
feel it’s squat, round, unusual, ugly dimensions give it a quality of it’s own. The wife has not been happy with some of my earlier attempts at garden aesthetics and after what this tree has been through, I may have to leave well alone.
Regards Chris
Chris
Your story is enough to touch the hearts not only of walnut growers but all who have loved trees and all whose love of trees has not been understood or supported by their friends.
As for harvesting, do nothing until they fall. This will happen without effort thanks to the wonders of gravity, although a timely shake once some have begun to fall could help. Then pick them up, wash them, spread them out somewhere with plenty of dry air-flow to dry, leave them a couple of weeks (defending them from rodents and misguided friends), gather them and eat them. The Omega-3 content will help you live long enough to harvest increasing quantities over the years to come.
You may also like do a little pruning to improve the shape during the winter.
Best wishes

Hi all,
I’m the proud owner of one tree. Intended as a shade
tree and purchased as a three year old. I lovingly looked
after my pride and joy for almost a whole month !! At a party in the back garden, an EX friend tripped, landing on the tree. Even novices like me know there is not too much a future for horizontal trees. Perhaps a tribute to my renewed
dedication, or just bloody good luck, this hardy specimen survived having its trunk snapped at ground level. Five years later, I am still the proud owner of perhaps the ugliest
walnut tree in Taranaki.
A few small fruit last year, better size and quantity this
year, brings me now to enquiring of you experts on how and when I should harvest the fruit.
Regards Chris
