It’s time to get your tomatoes out. It may still be a little warm where you are, and yet tomato season is over. But there are five or six crops you can plant after tomato season and still get a decent harvest for Thanksgiving.
Never plant tomatoes without this. For big fruits and more tomatoes, follow this
Short crops (those that take less than 45 days to mature) have the best chance of success in the fall. Start with radishes, which take 30 days to mature, and plant several varieties. You should also plant a few rows of beets: golden, red, Chioggia. Also plant turnips, both the white Japanese and the giant American varieties. You can also sprout rows and rows of carrots. If you plant a Little Finger, a Nantes variety, or a Parisian Market variety, you will probably get them before winter, but your larger storage carrots can grow all winter and will be waiting for you in the spring.
You have a narrower window for peas now than you do in spring, so I recommend choosing bush peas that grow three feet tall or less. There are plenty to choose from, and you should sow them right now.
Plant bok choy, which only grows well at this time of year, and then plant more in a week. Spinach is also growing like crazy now, as is Swiss chard. You might get lucky and Swiss chard will overwinter. Greens like mizuna also do well at this time of year. Kale will probably overwinter, so plant that in the ground.
