Late summer is the ideal time to start your fall garden. In most areas of the country, you can grow a "second season" crop of your favorite cool-season vegetables and lovely fall flowers. In mild winter areas, you can grow even more garden favorites for harvest in late fall, winter, even into next spring. Now is the time to gear up for some of the best growing weather of the year, which lies in the cool season ahead
What to GrowHome Garden Seed Association
Beets, calendula, cilantro, kale, lettuce, peas, radish, salad greens, spinach and Swiss chard.
Even where winters are cold, many vegetables can still be grown to maturity before first frost. In addition to the Top 10 listed above, try broccoli, carrots, cabbage and arugula. When choosing varieties, select ones that are fast-maturing to ensure a harvest before the cold weather hits. Consider extending your planting season even more by growing crops under cold frames and row covers. Now is also a good time to start seeds of many flowering perennials. Sown in fall, many will be ready to start flowering by the following spring or summer.
In mild winter areas, you can grow an even wider selection of fall and winter crops, including onions, leeks, and parsley. Seeds of annual flowers that thrive in cool weather can also be sown now for fall and winter bloom, including alyssum, candytuft, calendula, lobelia, stock, and sweet pea.
When to Start
Remember that sowing seeds or setting out transplants in midsummer can be more stressful to young plants than seeding during cooler, often wetter spring weather. Be sure to keep the soil moist as seeds are germinating. Protect young seedlings with shade cloth or plant them near taller plants, such as corn or tomatoes to provide shade from the hot afternoon sun. Another option is to start seeds in containers in a spot with high, bright light and then transplant young seedlings into the garden. This works well for crops like lettuce and spinach, whose seeds don’t germinate as well when soil temperatures are high.
With a little effort in late summer, you'll have a splendid harvest of vegetables in fall. Cool weather-loving crops, such as kale, lettuce, spinach, and broccoli, will thrive in the lower autumn temperatures.
