As you taste your first garden-fresh tomato of the
season, thoughts of planting your next vegetable garden may be the furthest
thing from your mind. However, now is the time to extend your supply of
fresh vegetables by planting a fall garden.
A late-season garden can include frost-tolerant and
hardy vegetables that don’t grow well in the heat of the summer.
Some, including broccoli and cauliflower, are actually of better quality
because of the cooler weather when the heads are forming.
Some vegetables to consider for your late-season
garden are broccoli, cabbage, cauliflower, snap beans, and carrots. These
may be planted until about July 20. Keep in mind that the average date of
the first frost in central Illinois is Oct. 7.
Plantings of lettuce, spinach, turnips, kohlrabi, and
radishes can be made in early September in central Illinois.
Before planting a fall garden, clear the area of weeds
and plant debris. Avoid working the soil unless it was not prepared in the
spring.
Begin your fall garden by planting seeds in accordance
with package directions. Cover the seeds with potting soil to prevent
crusting of the soil surface. The upper inch of soil should be kept moist
until the seeds have germinated. During the summer, this can be a
challenge; a light layer of straw or dried grass clippings may help hold
moisture in seedbeds. Once seedlings have emerged, pull back the mulch and
decrease the frequency of watering, but thoroughly soak the top 8 inches of
soil when you do water.
Broccoli, cabbage, and cauliflower are best started as
transplants. Set plants in the garden at the same level or just slightly
lower than they were grown in the container. If the roots are compacted,
loosen the roots by carefully breaking the soil ball apart. This loosening
helps encourage better rooting in the garden soil. Carefully firm the soil
around the plant and water well to eliminate air pockets. Water plants as
needed to maintain uniform soil moisture.
I have high hopes for my fall garden: Last year one of
my master-gardener volunteers grew a broccoli head bigger than a
basketball!
