You can sow seeds for winter vegetable crops, like salad greens, radishes, carrots, onions, Swiss chard, English peas and kale. Look for transplants of other cool-season vegetables, including Brussels sprouts, broccoli and cauliflower. Herb transplants also appear in garden centers during winter.
Fall is a great time to plant perennial herbs, which come back year after year and thrive in either pots or planting beds. Plant herbs such as thyme, oregano, mint, and sage any time from summer to mid fall, and you'll be able to harvest now and up until a hard freeze.
Freezing temperatures don't necessarily mean that planting is out of the question. As long as you can work with the ground enough to plant a bulb, then you can plant almost anything including plants that are currently in pots.
In warmer zones, the winter planting window is wide open. You can sow seeds for winter vegetable crops, like salad greens, radishes, carrots, onions, Swiss chard, English peas and kale. Look for transplants of other cool-season vegetables, including Brussels sprouts, broccoli and cauliflower.
SNOWDROPS (Galanthus nivalis)
True to their name, these early-blooming bulbs often emerge while snow is still on the ground to provide a breath of fresh air for winter-weary gardeners. In mild winters, snowdrops can flower as early as late January, but February or March is more common.
Mid-August to mid-October is an ideal time of year to plant new trees, though, that time frame can be stretched into November and December. To be 100% sure, measure soil temperature early in the morning for a few, consecutive days. If your soil is consistently 50° F or higher, you're good to plant.
From early fall through most of November is one of the best times of year to plant spring-blooming bulbs, cool-season annuals and vegetables, as well as many trees, shrubs, and perennials.
"Fall is an excellent time to plant almost any perennial, with the exception of many ornamental grasses, which are better planted in spring," says Erin Schanen, Troy-Bilt's gardening partner, a master gardener volunteer and creator of The Impatient Gardener blog and YouTube channel.
Fall and Winter LEAFY GREENS
A beautiful sampling of some of the leafy greens you can grow in your fall and winter garden, including different varieties of kale, spinach, lettuce, chicory, and even wild chickweed! Spinach is a very fast-growing, cool weather vegetable.
Broccoli, Brussels sprouts, cabbages, kale, leeks and parsnips are hardy vegetables and will stand through the winter.
Optimally, seeds should be started in late summer, but nursery seedlings transplanted in early fall will still do well. Some plants, such as onions, leeks, and cole crops, take a while to become established.
Although each plant's needs may vary and some will be more winter-hardy than others, in general about a month before the last fall frost is sufficient in giving the plant enough time to establish itself and take root.
Plant your fall vegetables so that the crops you choose have time to reach maturity before the first frost in your area. Find your first frost date, then count backward based on days to maturity for each type of veggie you want to grow. That's your ideal planting date.
It's important to cut back foliage in the fall to protect flowering plants from disease and give them a clean start for regrowth as winter starts to turn into spring. However, there are some plants you can keep around through the winter since they benefit wildlife and still offer visual interest for your home.
If you live in a frost-free region, October is a great time to plant cool-weather flowers and vegetables in your garden. Crops such as kale, cabbage, collards, lettuce, carrots, mustard, onions, Brussels sprouts, cauliflower, beets, and garlic can all be planted in early to late October.
You can transplant perennials anytime until the ground freezes in the fall, or wait to transplant them in the spring. Fall is an excellent time to transplant herbaceous perennials because your plants will then have three seasons to establish a good root system before hot summer weather sets in next year.
The answer is you can plant as late into the season as you are able. That is, as long as you are able to get a spade into the ground you can plant or divide. Where I live in New England, Zone 5b/6a, our ground usually doesn't freeze until December or early January.
