Silver King Corn is a popular variety of sweet corn that is well-suited for growing in Illinois. With its delicious taste and high yield, it’s a favorite among both home gardeners and farmers. In this article, we will discuss when to plant Silver King Corn in Illinois and how to grow it successfully.
Climate & Hardiness Zones in Illinois
Before we dive into the specifics of growing Silver King Corn, it’s important to understand the climate and hardiness zones in Illinois. The state experiences a diverse range of weather conditions, so it’s crucial to choose corn varieties that can thrive in your specific region.
Illinois is divided into several hardiness zones, ranging from zone 5 in the northern part of the state to zone 7 in the southern part. The USDA Plant Hardiness Zone Map is a reliable resource that can help you determine the exact zone for your area.
Zone 5 in northern Illinois experiences cold winters with average minimum temperatures between -20 to -10 degrees Fahrenheit. This means that crops like Silver King Corn, which require warm temperatures for optimal growth, may need to be planted later in the season to avoid frost damage.
On the other hand, zone 7 in southern Illinois has milder winters with average minimum temperatures between 0 to 10 degrees Fahrenheit. This allows for a longer growing season and the possibility of planting Silver King Corn earlier in the year to maximize yield.
When to Plant Silver King Corn in Illinois
When it comes to planting Silver King Corn in Illinois, timing is key. Generally, corn is a warm-season crop that should be planted after the soil temperature has reached a consistent 50°F (10°C) or higher. In Illinois, this typically occurs in late April to early May, depending on your location and the prevailing weather conditions.
However, it’s important to note that Silver King Corn is a variety with a long maturity period, usually requiring around 90 to 100 days to reach harvest. Therefore, it’s essential to take into account the average first frost date in your area, which typically ranges from late September to early October in Illinois.
Planting Silver King Corn is not just about timing; it also requires proper care and attention throughout its growth cycle. This particular variety of corn is known for its tall, robust stalks and large, sweet kernels. Silver King Corn thrives in well-draining, fertile soil with a pH level between 6.0 and 6.8. Ensuring the soil is rich in nutrients will promote healthy growth and development of the corn plants.
To ensure a successful corn crop, follow these steps for planting Silver King Corn:
- Prepare the soil by removing any weeds, rocks, or debris.
- Loosen the soil to a depth of at least 6 inches (15 cm) using a garden fork or tiller.
- Add organic matter, such as compost or well-rotted manure, to improve soil fertility and drainage.
- Sow the corn seeds, spacing them around 12 inches (30 cm) apart in rows that are 30 inches (75 cm) apart.
- Cover the seeds with soil, ensuring they are planted at a depth of around 1 to 1.5 inches (2.5 to 3.8 cm).
- Water thoroughly after planting and keep the soil consistently moist throughout the growing season.
As Silver King Corn matures, it will develop tassels at the top of the stalks, which release pollen to fertilize the corn silk. Each silk strand corresponds to a kernel on the cob, and proper pollination is crucial for full kernel development. Bees and wind play a significant role in transferring pollen from the tassels to the silks, so planting Silver King Corn near other flowering plants can attract pollinators to your garden.
Once the corn begins to form ears, it’s essential to monitor for pests and diseases that can affect the crop. Common pests that may target corn include corn earworms, armyworms, and corn borers. Regularly inspecting the plants for signs of damage and implementing appropriate pest control measures can help protect your Silver King Corn crop.
When to Harvest or Pick Silver King Corn in Illinois
Harvesting Silver King Corn at the right time is crucial to enjoy the best flavor and texture. The timing of harvest also depends on personal preference regarding sweetness and tenderness.
On average, Silver King Corn is ready for harvest approximately 80 to 100 days after planting, depending on the weather conditions and cultivation practices. However, there are a few signs that can help you determine when it’s time to pick your corn:
- The silks on the ears of corn turn brown and dry.
- The corn kernels feel plump and firm to the touch.
- If you peel back the husk slightly, the kernels should appear milky and juicy.
To harvest Silver King Corn, follow these steps:
- Hold the corn stalk near the base, just above the first ear of corn.
- Gently pull the ear of corn downward, twisting it slightly to detach it from the stalk.
- Inspect the ear to ensure it is fully filled out and free from any signs of pests or disease.
- Store the harvested corn in a cool place or enjoy it immediately for the freshest flavor.
It’s important to note that the sweetness of Silver King Corn can be influenced by the time of day it is harvested. Many farmers and gardeners believe that picking corn in the early morning, when the temperatures are cooler, can result in a sweeter flavor compared to harvesting in the heat of the day.
Additionally, the size of the corn kernels can also indicate the optimal time for harvest. While larger kernels may seem appealing, they can sometimes indicate that the corn is past its prime and may have a tougher texture. It’s best to aim for a balance between plumpness and tenderness when selecting ears for harvest.
