I too have nematodes in my 8'x4' bed. I know because of the knobby roots of the vegetable when I pulled out 3 eggplants, 2 tomato plants, and a squash last summer and the disappointing production. So far I have:
- Planted Naughty Marigolds every 7 inches where I pulled out the affected plants.
- I have saved my shrimp shells -- after rinsing, boiling, drying, and crushing them. I will add these to the bed.
- I have snipped my cauliflower leaves and added them to the bed to decompose in the bed. It's not mustard, so I hope this is a good substitute.
What I can't find is
clear plastic to solarize the bed coming of summer. Can I use 2 mil plastic sheeting normally used as tarp? The box says it's clear but it is opaque. Any other suggestions to help my bed?
I'm hoping to do this immediately after I harvest my garlic and onions in June. I don't even know if these nematodes will affect the onions and garlic. I also hope to add my compost as well.
