When is Late Winter? Late winter is 4 to 6 weeks before spring thaw begins. This could be any time in January to May, depending on your climate. Use your average last frost date and count back.
Note: The "late winter" period is the time from approximately mid-January through the end of February.
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.
In my mid-South (zone 7) garden late winter is February. The garden is still dormant but the spring thaw will begin within a month to 6 weeks. The job should be handled before new spring growth begins, but after the threat of severe cold has passed.
Winter vegetables need a solid start before winter arrives, because once cold, dark days settle in, plants won't grow gangbusters, like they do in the summer months. The general rule of thumb for planting a winter vegetable garden in Zones 7 to 10 is to plant during October.
Semi-hardy vegetables that can withstand light frost of air temperatures in the range of 28 to 32 degrees include beets, spring market carrots, parsnip, lettuce, chard, pea, Chinese cabbage, endive, radicchio, cauliflower, parsley and celery.
Late winter is 4 to 6 weeks before spring thaw begins. This could be any time in January to May, depending on your climate. Use your average last frost date and count back.
Some of the best performers in Zone 7 and 8 winters are arugulas, beets, swiss chard, mustard, cauliflower, radishes, spinach, broccoli, carrots, cabbage, peas, turnips, and varieties of lettuces. When shopping for seeds, keep a keen eye out for varieties that boast cold hardiness and have shorter maturation periods.
When you're ready to trim, remember the rule of thumb for how far to cut back perennials. At a slight angle, trim the plant nearly all the way down to the ground, leaving about a 1-to 2-inch stub above ground. Spray your pruners with alcohol or Lysol in between cuts to sterilize them.
Some farmers have been hesitant to adopt the practice of planting early because a late-Spring frost can reduce the yield potential gained by planting early. However, planting later not only reduces yield potential, but also presents the risk of an early-Fall freeze.
Fall is Good for Root Growth
Warm soil temperatures encourage root growth – more so than in the spring when the soil is still warming up. Plus, with the shorter days and cooler air temperatures, plants spend less energy on growing foliage and flowers and more on building a strong root system in preparation for winter.
For the Northern Hemisphere, the months of January and February are typically the coldest. The reason is due to cumulative cooling and a relatively low sun angle.
fall (autumn) runs from September 1 to November 30; and. winter runs from December 1 to February 28 (February 29 in a leap year).
December – Early winter. January – Mid-winter. February – Late winter.
These cold-weather champs are kale, spinach and collards. Other hardy vegetables include broccoli, Brussels sprouts, English peas, kohlrabi and leeks. Hardy root crops are radishes and turnip, which also yields some greens from the tops. Other hardy greens include kale, mustard greens and collards.
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.
The “Dead of Winter” is an old saying that refers to the coldest part of the winter season. For most of the northern hemisphere, that usually means the month of January. While actual daily weather varies, historical average temperatures typically reach their lowest point of the year between January 10 and February 10.
The winter of 1880–1881 is widely considered the most severe winter ever known in many parts of the United States. The initial blizzard in October of 1880 brought snowfalls so deep that two-story homes experienced accumulations, as opposed to drifts, up to their second floor windows.
By the meteorological calendar, the first day of winter is always 1 December; ending on 28 (or 29 during a Leap Year) February. Meteorological seasons consist of splitting the seasons into four periods made up of three months each.
At temperatures below 15° C, photosynthesis and plant metabolism slow, stopping growth as it waits for better conditions. As soon as the temperature rises, the plant resumes full functioning.
Seedlings, with their tender new leaves, often give up the ghost when temperatures dip to 32-33°F. Tropical plants have differing low-temperature thresholds. Some keel over when temps fall to 40°F; others crumble at 35°F. Other plants are just hardy by nature and can withstand temperatures as low as 18-20°F.
Second, know that a light frost—32°F and colder—kills all tender plants such as tomatoes. Hardier plants such as spinach and kale will survive until there's a hard freeze—28°F and colder.
