The arrival of spring and early summer in Illinois brings the highly anticipated season for local strawberries. These bright red berries offer a flavor and sweetness unmatched by fruit shipped from warmer climates. Understanding the short window of the local harvest is paramount for consumers seeking the freshest possible fruit. The seasonality of this crop determines the best time to visit a local farm or market for peak quality and flavor.
Defining the Harvest Window
The primary strawberry crop in Illinois comes from June-bearing varieties. These plants produce one large, concentrated harvest, typically beginning in late May and peaking throughout June. The U-Pick season for these main varieties is notably brief, generally lasting only about three to four weeks from start to finish.
This short harvest period ensures a large yield of the biggest, most flavorful berries, which are excellent for fresh eating and preservation. Some farms may also grow ever-bearing or day-neutral varieties. These types produce smaller flushes of fruit later in the season, sometimes yielding berries into the summer and early fall, though their overall production is smaller than the main June crop.
Regional Differences Across Illinois
Illinois’s length from north to south creates a variance in when the strawberries ripen. The growing season progresses northward, meaning Southern Illinois often starts its harvest earlier than the central and northern parts of the state. Farms in the far south, near regions like Murphysboro, may see their first ripe berries appear as early as the first or second week of May.
Moving into Central Illinois, the harvest generally begins in the latter half of May and extends into early June. For Northern Illinois, including the Chicago metropolitan area, the season usually commences later, peaking in early and mid-June. This difference can be a delay of 10 to 14 days between the southern and northern extremes of the state. Growers often divide the state using major interstates like I-70 and I-80 to mark these distinct regional harvest zones.
Finding and Harvesting Local Strawberries
The two primary ways to acquire local strawberries at their freshest are through U-Pick farms and farmers’ markets. Visiting a U-Pick farm requires preparation, such as calling ahead to confirm field conditions and berry availability. Since strawberries are sensitive to weather and high demand, fields can be picked clean quickly, making an early start advisable.
When picking, select only berries that are fully red, as strawberries do not continue to ripen once detached from the plant. The correct technique involves grasping the stem just above the berry with a slight twist to detach the fruit. Wear long pants and closed-toe shoes or boots, as fields can be muddy or have rough plant material. Do not overfill containers, as heaping berries more than five inches deep can crush the delicate fruit underneath.
Farmers’ markets offer a great alternative for securing fresh fruit. Buyers should arrive early to secure the best selection, especially during the peak weeks of the season.
Post-Harvest Care and Usage
Freshly picked strawberries have a short shelf life, making immediate and proper care essential to preserve their peak flavor. The berries should not be washed until immediately before they are ready to be eaten or used in a recipe. Washing them prematurely introduces moisture that encourages mold growth and rapid spoilage.
The best way to store fresh berries for short-term use is in the refrigerator, loosely covered to allow air circulation, and they should be consumed within two to three days. For preserving a large harvest, freezing is the most common method to maintain quality.
To prepare for freezing, wash and hull the berries, then ensure they are completely dry to significantly reduce ice crystal formation. The berries should then be spread in a single layer on a baking sheet and flash-frozen until solid before being transferred to a sealed freezer bag. This technique prevents the berries from clumping together and helps maintain their texture when thawed.
