They require a cold period to bulb correctly and can be planted in the fall for a summer harvest. Spinach is another crop that can brave the Illinois winter, and its leaves can be harvested in early spring.

Lastly, broad beans and peas can be sown in late winter to get a head start for spring harvesting.

Summer in Illinois brings warmth, making it an ideal time for growing many vegetables. Tomatoes, bell peppers, and zucchinis are the easiest crops to grow in Illinois during summer. These vegetables love the sun and are relatively easy to manage. Cucumbers, often used for salads or pickling, can be sown directly into the ground in late spring and will produce abundantly in summer. Furthermore, green beans are not only easy to grow but also provide high yields in a short amount of time.

Spring Vegetable Planting Guide for Illinois: Top Choices for a Bountiful Harvest

Spring is a season of renewal and is an excellent time for planting a wide range of vegetables in Illinois. Carrots, beets, and radishes are root vegetables that can be started early in spring, promising a tasty harvest. Lettuce and other leafy greens like Swiss chard and arugula thrive in the cooler temperatures of spring.

Additionally, potatoes can be planted in early spring, ensuring a plentiful yield come summertime.
