    Hi NZWIG We have a house in Hawkes Bay and we have a huge walnut tree.We are picking them off the floor and putting them in net bags to dry and i read on internet they should be ready to eat or give away in 6 weeks..We have just moved here so this is are first crop.
    We have bought small net bags as that is all we could find.
    Any advice for novices would be great


    • Hi Jacqui, Walnuts always taste better when they’re dried as soon as possible after they come off the tree. It’s likely that even in net bags the ones in the middle won’t dry out properly and may even go rancid and mouldy. We would recommend laying them out on a rack only one or two nuts thick for a at least month before they’re bagged up.

    We bought a property in Amberley in 2012 after the quakes and to our delight found a fairly large walnut tree,( bent and on a 20 degree angle, which we think has been bent for years), growing in our backyard. We were unable to gather nuts in our first year because of the grounds being very untidy. The 2013 harvest gave us 6kg of cleaned up nuts; 2014 it became, 7 kg and 2015 ,it was 8 kg. We have mostly given them away as gifts to friends, together with enjoying them ourselves.This year disaster struck:with hundreds of nuts falling off the tree far to early. We presume it has a disease of some sort. Taking nuts out of its overcoat right now to ceck them out they are mainly black on the inside. Still a good number of nuts are still on the tree and we are hoping that these may stay there and fall off at the right time as in previous years in their hard husks but then we are certainly not sure about that. Can anyone give some advice ? I have read it might have a disease called :BLIGHT .Rayma and Jacob.

    • Nelson Hubber says:

      Hi Jacob and Rayma,
      This year is a bad one for blight so that is probably what it is. Walnut Blight is more evident in wetter seasons. Commercial walnut growers use copper spray applying several applications in a season starting at bud burst, Large horticultural type air blast sprayers are used but this is hardly practical for one tree. The best advice is probably to take the seasons as they come and in dryer years it will be less of a problem.

      • Jacob and Rayma Schriek 03-3149520 AMBERLEY 7410 says:

        So much appreciated for your advice.. We may be able to salvage some of the nuts still on the tree. We hope so ..Indeed, spraying them is well beyond us so we will take the years as the come. The past few years in North Canterbury have been very dry so it would not be because of too much rain. All the creeks have been dry for 9 or 10 months these few years and we have a dry creek right along the rear boundary of our property with the tree about 2or 3 meters from the creek. Our back neighbour said it is the first time in 17 years the creek has been dry, since he first built his house there. We appreciate your help..
        Again, thank you.
        Our best regards ,
        Rayma and Jacob Schriek

    I am interested in planting some walnut trees on a block of Land just out of Alexander. What would be the best variety to plant.the land is pretty much clay and gravel with some better ground in other areas.

    • Nelson Hubber says:

      Hi Kerran,
      Haven’t caught up for a long time. How many trees are you thinking of? Home use or commercial?
      There are late frosts in your area so Franquette would be a good variety to combat this but it tales a few years to produce. Darrell Johnston of River terrace Nurseries at Brightwater near Nelson is a good person to get grafted trees from, email rivernuts@tasman.net

    How do you propogate walnut trees from your own walnuts?

    • Nelson Hubber says:

      Just pop healthy mature nuts in the ground, not too deep and most will germinate and grow into trees. However commercial growers use grafted trees because they produce earlier and are true to type whereas there is huge variation in trees grown from the nuts and some may never produce

    • Trudi Meyer says:

      Try your local farmers markets, some shops stock NZ walnuts. Or try A Cracker of A Nut (as you live in Timaru). They are walnut processors (a grower coop). They are in West Melton (west of Christchurch). Have a look on their website

    • Hi Roly
      The nearest supplier to you that I know of is;

    Dear NZWIG,

    We live in Drury, 40km south of Auckland and have a spare 2 acres of land for growing something and our thought is to grow walnuts.
    We have heard that Wilson’s Wonder could be a suitable species for this region.
    Our soil is a heavy loam. We have shelterbelts as the site was once an apple orchard.
    Would this type of crop be a viable option?
    Having read some great stories about walnut growing we would love to learn a bit more about it.

    Gary is a landscape designer and is keen on utalising our extra block of land.
    Thanking you for your reply,

    Gary and Agnes DeBeer
