lots of green peppers? make sweet hamburger relish. about half green peppers and half cukes.
or just freeze them. if you don't cook with them (like me) , fry them up with onions. sooooo goood like that, i think.
that's what i do, at 64. still try to can or freeze as much as i can. try to can, then as i get tired, or not have enough for a canner full, i freeze.
nemotodes? i'm going to have to look that up. lots to do for that sandy soil. manure the heck out of it. old straw or hay, grass clippings, leaves, dig a hole and plant your garbage. last resort, compost. fertilize. you would be surprised, with fertilizer and water, a lot of times, you can raise something.
