Is anyone else troubled with nematodes and if so what do you do and it doesn't have to be an organic remedy I am about ready to try anything...
Nematodes
Go to Market Growers forum. Lots of discussion on it there.
Are you talking about bad nematodes or beneficial nematodes?
Years ago I had root stinging nematodes in my garden, the extension agent said he had never seen them around here because they are usually found in sandy soil, I have rock. I figured out that they came with the construction sand that my ex husband put in my huge garden even though I had ask him not to. I used a product called Sarolax by hi-yield but I don't think it is on the market any more. You might be able to find it some of the smaller feed stores still. Then when I did plant I poured vegtable oil in each hole this way the plant's roots got a chance for some healthy growth before they got stung.
I have to admit it was probably the most frustrating garden problem I have ever had. To see healthy plants stop growing and then wither up and die right before your eyes is crazy making. Besure you clean your gardening tools really well so you don't spread the D.... things.
