Chicago, Is It Safe To Plant Yet?

The 10-day forecast is looking pretty decent Chicago (zones 5-6), save for tomorrow’s night time temp in the mid-40s. Dare I risk making a predication that we’ll be in the safe planting zone starting the end of this week? I don’t foresee frost being an issue, but many varieties of warm weather veggies don’t like cold nighttime temps- unlike leafy greens which thrive under cooler conditions. ┬áSo if you’re thinking spinach and lettuce, the 80’s we’re receiving this week is not a good seeding climate. Everything else, however might just be in the clear. But don’t take my word for it, I don’t want anybody knocking on my door with shriveled or stunted seedlings if we have a midwest surprise!┬áStart the conversation here… what are you planting and when?

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.
