preventing the spread of root-knot nematode
I discovered root-knot nematode galls on the roots of a single fig tree that's been in the ground 5 years. I can always plant more fig trees, but I have 12 young pomegranate trees of rare cultivars in my yard that I want to protect from this. There is no evidence of rkn on any of their roots. What would be the best way to protect my poms? I'm pretty sure this fig came from the nursery with rkn and I just wasn't aware of the disease. Do I need to dig up the fig along with the dirt around it, or would this increase the chance of spreading rkn? I'm pretty sure I wouldn't be able to get all the roots from the fig up as it has become fairly large.
