As the end of the tomato season approaches, there are several things you can do with your tomato plants to maximize your harvest and prepare for the winter. Here are some tips from the search results:

1. Harvest the last tomatoes, even the green ones. You can pull the entire plant out, roots and all, or cut them at the base and allow the roots to decompose.
2. Watch out for disease. Check the plants carefully for any signs of disease before deciding whether to discard them or compost them.
3. Remove plant materials. Pull up spent tomato plants and weeds, collect dropped or “mummified” fruit, and rake the garden to remove plant remnants. Burn or discard plant materials, including roots.
4. Protect your plants from the cold. You can wrap your plants in a tarp, old sheets, or burlap to get them through chilly nights. Remove the coverings during the day. Tomato plants can also be protected in a cold frame, tunnel, or greenhouse.
5. Prune off late-season shoots from your indeterminate tomatoes to focus the plant’s energy into the blossoms and fruit that are viable.
6. Ripen green tomatoes indoors. Store green tomatoes in a paper bag with a ripening apple or banana, or wrap unripe tomatoes individually in newspaper and store them in a dry, dark location.

By following these tips, you can make the most of your tomato plants at the end of the season and prepare for the winter months.
