I know that in organic gardening French marigolds are used as a nematode
repellent. There are beneficial nematodes as well however, and even ones
that prey on others.

I would like to learn more about crop rotation protocols, what crops
follow and how many years between bulb crops. In a garden situation, or a
small field how much 'space ' is needed separating crops, or are there trap
crops to use as cover cropping for nematode, virus and root rot diseases.

huge producer of cut flowers but that is all gone now too.
