Since you are located in DC it is hard to know how long your plants will go into the fall. Kale is a good fall crop and turnips (Hakeuri) are small and can be planted together. Spinach and arugula can be planted late in the fall and will overwinter and continue to grow in the spring.
Take a look at our website on floating row cover which can extend the season. http://extension.umd.edu/sites/extension.umd.edu/files/_docs/programs/hgic/HGIC_Pubs/Edibles/GE004_2...
If you decide not to plant in some of the beds, you can plant a cover crop to protect and improve your soil. You can plant as early as mid August but usually no later than mid October. http://extension.umd.edu/hgic/cover-crops-protect-and-improve-your-soil
