Planting Fall Crops in Chicago and the Great Lakes Region

Well, the strawberries are loving the late summer heat and putting out some serious runners and fruit. This week I pulled up some ugly looking squash plants that were starting to die back. That gave me space in a few planter boxes for fall crops, including some deep red chard seedlings. I hope to squeeze out every last drop of warmth from the season and harvest right through first frost.

Mid to late August and even into early September is a good time to plant early harvest vegetables in the Great Lakes region. Some crops will mature before first frost while others can withstand light frost and be productive through October. Chicago can expect an average first frost around October 14th, which is a week later than much of Illinois due to our position on the lake and micro-climates caused by the urban heat effect. That gives us plenty of time to plant veggies with 50 to 55 days maturity.

Vegetables that can be planted now include greens such as chard, collard, kale, spinach as well as lettuces. When it comes to radish, peas, beans, beets, broccoli and cabbage, look for early maturing varieties and plant now. In the northern Great Lakes it may be too late for some of these crops, so check a frost chart for your area to determine how many days you have left in the growing season.

Here are some charts that will help:
