What not to plant in the fall?
If you are new to gardening, you may not realize that—even if you had some leftover seeds—heat-loving veggies such as peppers, beans, squashes, and eggplants cannot be planted in fall gardens because they will not have enough time to fruit before a frost. Broccoli, cauliflower, and Brussels sprouts are best started as transplants in the fall garden. Lettuce, carrots, and greens—including mustard greens, turnips, collards, and chard—can be direct-seeded into the garden soil.
Should I plant in October?
October is the perfect time to plant trees, shrubs, conifers, and hardy perennials—or spring bulbs like tulips and daffodils—and if you’re looking to sow cover crops or install lawns, now is the time for that as well. October is one of the best months to plant hardy perennials and herbs. Many are looking great now including toad lily (Tricyrtis), hardy cyclamen, and Japanese anemones, as well as evergreen perennials like Heuchera, rosemary, and lavender.
