Nematodes in Bonsai

Hi all,

Ryan has discussed briefly in Q&A V the application method of Nematodes, as done at Mirai.
Does any one have knowledge on what type of Nematodes we should use in Bonsai Cultivation and for what pathogens?
Sorry if i sound ignorant :slight_smile:
Thank you

Go to the Arbico Organics website. They have three different species of beneficial nematodes with descriptions of their characteristics. You can buy them in a three-pack, if you want. They’re not cheap, though.

I wish it was that easy … I’m in the UK.
Thanks for the info - I will look into the type of Nematodes and see if i can get the same species in the UK.

I shirley hope you are discussing beneficial mycorrhizae (fungus that are endosymbionts with the tree roots). Really beneficial. And healthy.
Nematodes… Not so much for the tree.
I assume I do NOT have BAD PESTS, if any, in my bonsai soil for flatworms to attack.
Hmmmmm… Systemic bug killer…
?

I am not talking about mycorrhizae. Nematodes are used for controlling plant pests in a Biologically friendly way. They attack the pests - they do not harm the plants. A systemic pesticide would kill beneficial bacteria in the soil (with the possibility of affecting the plant in a negative way) - Nematodes do not.

Take a look at Viresco UK and see if it offers you anything. I use some of their products.

Will do, thank you for the link.

Got the same thoughts and are looking for a web shop that ships to Germany?!?!?

@Jurgen, there are several products available in Germany i.e. from Neudorff.

Does anyone have results from using Beneficial Nematodes? Pictures of before and after would help.

I have used the nematodes in the link above but have bought them from gardening naturally website, a little cheaper.

I have used the nematode which kills vine weevils on a whole batch of field grown trees in grow bags and also some nursery stock that were all riddled with vine weevils. It was probably a little over kill as I had bare rooted everything and washed the roots already. Everything is doing fine.

I have also used the cutworm killing nematodes on my vegetable garden and the ant one when preparing the base for my greenhouse after disturbing a few ant nests when removing turf. All seem to have worked well.

They are a living product so have to be used within a week or two of purchase and you have to protect against cold temperatures as well for a while after application so can only be used at certain times of year.

Hi guys, I’m living in Czech Republic and I would like to try out these wormies. I think buying from the UK will probably cost a bit. Is the German Neudorff, the place to go?

Been reading… still see no healpfull, usefull, reason for this application. Palative? Looking for a problem? I might if I had an infestation? Each type of nematode is pretty specific to a larvae species.
I did try BT on my tomatoe horn worms once. Not impressed. Chickens and ducks decimated them, though.
BUT, then, I avoide using bug spray or antifungal much; either; mostly, except for…hhhmmmm.
.
Nematodes…they are used to control ants, fleas, moths, beetles, flies, weevils, and other larval pests.
Except the odd earthworm, I’ve never seen bug larvae in my BONSAI SOIL. I would notice them and recognize they need to be addressed… I DO see parasitic wasps, lady bugs, spiders, and praying mantis on the trees. (I had to look up the lady bug larvae form!)
.
Did read this: Chryseobacterium nematophagum – or golden death bacillus – that effectively kills a wide range of important nematodes. Interesting… I would not want to cultivate THAT in my backyard…
.
That being said, I have not broke out my microscope yet to REALLY see what is in MY bonsai soil. If I am using good organic techniques, AND there are any larval bugs in it, I will probably find nematodes too!

Life has a way… balance of water and oxygen.
Have a beer… wire a tree…
Oooohhhmmmm…
(More later if I find anything interesting…)
