My garden.

I'm very pleased with my science experiment this year. I'm going to do a few things different next year. I'm going to get heavier wire for the tomato plants. I think I'm going find a better pesticide for the corn. Perhaps I'll even build a mini green house to place over the green peppers to help them grow better.
Now the season is nearly over. I have no idea what to do with my plants that are dead/dying. My corn is kaputz and a big wind storm knocked them over and broke them so I can't use them for Halloween decorations like I was planning. My cucumber got a little frost and is turning brown.
So... do i mulch the plants back into the soil or do I throw them away?
Any ideas????
