I last post I described our establishment concept where planting of the vole desirable trees and shrubs occurs in nätkorgar galvanized putsnät. We've built well over 100 nätkorgar late last year and start getting into a good technique now. The network we use is that said mesh size 12,7 mm. Larger than that, vole probably get through. We purchase online at 25 m long rolls and to cut it on a workbench. On the bench we have made instructions for different pot sizes, so we do not need to measure the length of each time. Nätkorgarna usually have 15-25% larger diameter than the pot plant stand in:
The height of nätkorgarna varies, but we want them to be around 5 cm deeper than the root system and that they will stick up above the ground with at least 5 cm. heights 25-30 cm is usually adequate for most smaller trees and bushes.
To cut online, we use a metal shears. Then you can cut several wires simultaneously. With practice, you can very quickly this way. We usually make three nätkorgar at the same time. The slightly narrower fourth row (the far right in the picture) we make the bottoms of the latter.
It is important that the baskets are provided with a bottom. Otherwise vole burrow under the trees and access to the roots that way.
To assemble the baskets and attach the bottom part we use a small pair of pliers (eltång). We turn thread ends (as well be provided as long as possible during the cutting) to fasten the various parts. It's good to do it pretty well, so that there will be gaps in the basket when filled with soil at planting.
Planting plants in nätkorgar differs little from conventional planting. More on that in the next post.
Nu väntar vi på nästa inlägg om planteringen i korgarna 😀.

Hi, a question about the network used. After searching, I found hot-dip galvanized mesh in the right dimension. Have you tried this? Does it also work or does it stay in the ground too long? As I understand it, hot dip galvanizing provides a more durable rust protection, but my knowledge of this is very deficient.
Hi Axel,
we use hot-dip galvanized mesh. I dug up some old mesh baskets I made from hot dip galvanized chicken wire a few weeks ago and it turns out they were completely broken down after only two years. Chicken netting has much thinner threads than plastering netting, but it seems to break down faster than I thought. Now I am a little worried that the cleaning web will not last long enough, but we'll see. In the Spanish study, held it in the least 7 years, but perhaps our soils nature of matter also. I think in any case that galvanized mesh will keep for a long time.
Greetings
Philipp
Thanks so much! Then we try galvanized putsnät. It is likely that Spanish soil is dry during the greater part of the year and that can perhaps give a longer life to the basket.
What good baskets!
1) I'll be planting lots of tulips in a lawn, it can work for that too? Could you imagine making a basket with a lid on so that you can have soil on top and then grass? So that it is possible to mow the lawn other parts of the year and so that the basket is hidden?
How would you do?
2) Sork scares are an idea to invest in? What kind / brand in that case?
Thousand thanks!
And, the baskets work very well! You can definitely try making a basket with a lid for the tulips. We have not had any major success with voles, but some say they work well, especially on a smaller scale. There is a post about sork in general here: https://xn--skogstrdgrden-hfbr.xn--stjrnsund-x2a.nu/sorkbekymmer-del1/.
Hi!
Have you had any problems with the roots of trees being "strangled" as they grow through the local baskets?
Hi! No, the galvanized mesh also breaks down and the roots are actually stronger than the mesh and crack it up when they get a little coarser. You can find some more information about it in this post: https://xn--skogstrdgrden-hfbr.xn--stjrnsund-x2a.nu/etablering-a-la-puttmyra/.
(the comment applies to water voles)
SHELL
You can also use crushed seashells (bought as chicken feed) and a comparison with 10 or so trees with and without, it was only those without crushing that suffered damage.
I also use it in combination with baskets (but only at the bottom when there are blueberries)
DIAMETER 40-60 CM
I don't want trees and bushes to survive but for them to grow decently so I use baskets as well 60 cm diameter for fruit trees and 40-50 for berry bushes. Around 13x13mm squares (except 20×20 in experiments with rhubarb. My Victorias just got eaten. Now I'm testing others. My fine Elmblutz with just a little of the child poison oxalic acid(the jumper) shall be protected by 13×13 but they grow well in pots too)
The depth ? 60 cm net, 10 cm above ground and a little too unattached, but becomes 45-50 cm underground. Bptten of course. I also put seashells in the bottom and later that I put in soil. A side note – compost or topsoil is used – use original compacted soil, otherwise the plant will gradually sink.
HOT GALVANIZED
As the blog writes – don't accidentally buy cold/galvanized. It rusts away immediately. Two years for HOT DIP GALVANIZED as the blog writes worries – lucky I was generous with seashells.
AUTUMN PLANTED?
If you planted recently and know there is field willow? According to SLU Report 2010:26 so the batten vole mainly eats roots during the early winter (but then through the winter) then it may pay to replant. Alternatively, bury the net afterwards – have done it with with small apple tree that was affected this year. A net of one meter in diameter followed by a root with a shell…
DRY
Is it dry like 2018 can the field vole gnaw bark in the summer according to the aforementioned report – not only in winter.
However, my information comes from different sources – and practice. And experience lifting a tree straight up – completely rootless. It won't happen again!
Tack för denna information!
Några frågor:
Var hittar ni galvaniserat putsnät med 12,7 mm mesh size? När jag letar hittar jag endast 19 mm maskstorlek på de nät som heter putsnät.
Jag gissar att tråddiametern har betydelse för hållfastheten.. Vilken tråddiameter har ni i dessa nät?
Regards
