If it works well I might plant tomato plants during Autumn each year rather than Spring. We go through stress for 'economic efficiency' (plant spinach instead so that you double your crops in the same space), but less efficient methods can be much more enjoyable and easier.
The ideal is to plant your harvested tomato and pepper seeds in among the spinach or other greens so they are sheltered by cold tolerant annuals which will reach maturity and be removed about the time most people start their transplants.
One of our co-op directors had a low tunnel full of cherry tomatoes. at the end of the season she pulled the spent plants and closed it up for the winter. The soil was covered in fallen tomatoes so when she opened it to plant the next spring there was a solid carpet of little tomato plants ready to transplant. The natural way to plant the nightshade family is to let the fruit rot on the ground.
I wanted a summer ground cover to keep the ground open so I could transplant raspberries in the winter. I bought a bag of bird seed and sowed it on the bare ground, mulched it with grass clippings and watered it thoroughly. I now have ripening about ten times as much millet, sorghum, thistle and sunflower seed.
The golden flax and lentils dried out early so I only have about as much as I planted to harvest for the chickens. My old hens have become experts at recognizing seed heads and pods to thresh their food so all I have to do is through the mature plants in the tractor to feed them. They are working their way through the dwarf apple orchard now eating the wheat that came up where they buried seed they missed. This process started when a friend plantd wheat for a cover crop but then was not able to plow it in the spring. I mowed it with my scythe and stacked it in the barn to throw them a bundle each day.
Don't work any harder than necessary. let things reproduce as they naturally do.
