Midwest Fall Edible Garden

Fall is a great time to garden!  You don't have to worry about pests and there is typically good rainfall so you don't have to worry about watering.  The crops that thrive in spring, thrive in fall.

For fall gardening, you actually start some varieties as early as July.  These will be the same type of veggies you planted for your spring garden.  You may have to start some varieties indoors as some seeds will not germinate in the hot temps of summer.  You can extend the fall harvest by covering your veggies with crop fabric when chilly temps arrive in late October so you can harvest all winter.

Don't worry if you are just getting started now; there are plenty of cool season crops you can start from seed in September and many you can order on line or pick up at your local nursery or big box store if you are getting a late start or just want to grab plants and plant.

Crops fall into 2 categories-cold season and warm season crops.  Warm season crops are those that abhor frost or getting their feet chilly.  Most of the warm season crops are killed by frost and won't grow unless the soil is nice and warm.  Cold crops are those that prefer when temperatures are cool or downright cold.

A rule of thumb is that if you eat the tuber, leaf or flower, it is typically a cold season crop.  If you eat the fruit or seed, it is a warm season crop. 

Choose the Right Varieties

In addition to choosing the right plants for cold-weather harvests, you can also increase fall harvests by planting specific varieties bred for colder climes. Look for varieties marketed as: fast-maturing; short and compact; textured (such as curly kale and Savoy spinach), winter-hardy, frost tolerant, overwintering, for every season, year-round, remarkably cold hardy, etc. 

Because daylight hours are getting shorter in the fall, you will need to add about 2 weeks to the “Days to Harvest” your seed packet gives as the seed packet dates are based on spring planting.  Plants grow slower in fall because the days are getting shorter instead of longer.

Just like in spring, seeds have to be kept moist to sprout.  You can also plant the seeds in peat pots or you can reuse the plastic annual trays you got in the spring.  You can put the plastic trays in a water catch pan, find a shady spot convenient to watering, fill with seed starting mix, sow your seeds and keep moist.  When the seedlings get their true leaves on them (second set), they are ready to transplant into the garden or a larger pot.

Outdoor seed starting tips

There are some veggies that the temps are too high to germinate in our Zone 7, like lettuce.  These you will have to start inside or on the cool side of the house in the shade or indoors if you're having a really hot September.  Once the highs get down into the 80's, you're generally safe to start outdoors in the shade.

October

The month to plant garlic for next year’s harvest and over-wintering onions.  Order your favorites early as many sell out quick.

October is prime time to plant garlic

If you don’t want to start seeds, some big box stores and local nurseries have begun to have fall planting veggies.   If none in your area do, there are many mail order seed companies that carry fall bedding plants.
