Climate & Hardiness Zones in Illinois

When to Plant Ruby Queen Corn in Illinois
Timing is crucial when it comes to planting Ruby Queen Corn in Illinois. You want to make sure that you sow the seeds at the right time for optimal growth and yield. Generally, corn is a warm-season crop, and the soil temperature should be at least 50°F (10°C) for successful germination.
In Illinois, the ideal time to plant Ruby Queen Corn is typically in late April to early May. By this time, the soil has warmed up, and the risk of frost has passed. Planting too early can lead to poor germination and stunted growth due to cold temperatures.
Before planting, prepare the soil by tilling it to a depth of 6 to 8 inches. Incorporate organic matter, such as compost or well-rotted manure, to improve soil fertility and drainage.
Once the soil is ready, use a garden hoe or a rake to create furrows that are approximately 1 inch deep. Space the furrows about 30 inches apart to give the corn sufficient room to grow.
Place the Ruby Queen Corn seeds in the furrows, spacing them about 6 inches apart. Cover the seeds with soil, gently firming it down to ensure good seed-to-soil contact. Water the area thoroughly to promote germination.
Note: Some gardeners prefer to pre-soak the Ruby Queen Corn seeds overnight before planting to encourage quicker germination. While optional, this method can be beneficial, especially in cooler climates.

Once the plants have reached a height of 12 inches or when the tassels appear, side-dress them with nitrogen-rich fertilizer.
3. Weed Control:

When to Harvest or Pick Ruby Queen Corn in Illinois
Knowing when to harvest Ruby Queen Corn is crucial to enjoy its optimal taste and sweetness. To determine if the corn is ready for harvest, keep an eye on these indicators:
1. Ear Development:
Wait until the ears of the Ruby Queen Corn have fully developed and reached their mature size. The ears should be well-filled and have plump kernels. Gently peel back the husk to inspect the kernels. If they appear milky and exude a milky sap when pressed, it’s a good indication that the corn is ready to be harvested.
2. Silk Appearance:
The silk of the corn, which emerges from the husk, turns brown as the ears mature. Monitor the color change in the silk. When the majority of the silk has turned brown, it’s a sign that the corn is almost ready for harvesting.
3. Taste Test:
If you’re uncertain about the maturity of the corn, you can always do a taste test. Carefully peel back the husk of an ear and sample a few kernels. Ideally, the corn should be sweet and tender. If the kernels are firm and lack sweetness, it’s best to allow the corn to mature further on the stalk.
When it’s time to harvest the Ruby Queen Corn, simply grasp the stalk firmly and pull it downward with a twisting motion. This should detach the ripe ear from the plant. Immediately after harvesting, cook or eat the corn to enjoy its peak flavor and freshness.
