Ruby Queen corn is a popular and delicious variety of sweet corn that is well-suited for growing in Wisconsin. With its vibrant red kernels and exceptional flavor, it’s no wonder that many gardeners in the state are eager to give it a try. In this article, we will explore when to plant Ruby Queen corn, how to grow it, and answer some frequently asked questions about this tasty crop.
Climate & Hardiness Zones in Wisconsin
Before diving into the details of growing Ruby Queen corn, it’s important to understand the climate and hardiness zones in Wisconsin. The state is known for its unique weather patterns, which can vary from cool and mild in the north to warm and humid in the southern regions.
According to the United States Department of Agriculture (USDA), Wisconsin is divided into four hardiness zones: zone 3 in the northern part of the state, zone 4 in central Wisconsin, and zones 5 and 6 in the southern regions. These zones provide a useful guideline for determining the appropriate timing for planting and harvesting crops.
Wisconsin’s climate is greatly influenced by its proximity to the Great Lakes, particularly Lake Michigan and Lake Superior. The lakes have a moderating effect on temperatures, leading to cooler summers and milder winters near the coastlines. Inland areas, on the other hand, tend to experience more extreme temperature fluctuations throughout the year.
It’s worth noting that Wisconsin’s weather can be unpredictable, with occasional late frosts in the spring and early snowfalls in the fall. Gardeners and farmers in the state often have to adapt their planting schedules to account for these fluctuations and ensure a successful growing season.
When to Plant Ruby Queen Corn in Wisconsin
When it comes to planting Ruby Queen corn in Wisconsin, timing is crucial. This variety is considered a warm-season crop, meaning it requires a certain amount of heat to grow and thrive. It’s recommended to start planting Ruby Queen corn when the soil temperature reaches a consistent 50 to 55 degrees Fahrenheit (10 to 13 degrees Celsius).
In most parts of Wisconsin, this typically falls in late spring to early summer, around mid-May to early June. However, it’s always best to check the soil temperature using a soil thermometer to ensure optimal conditions for planting.
Before planting, prepare the soil by removing any weeds or rocks and incorporating organic matter, such as compost or well-rotted manure, to improve fertility and drainage. This will provide a strong foundation for your corn plants to establish their roots.
If you are planting Ruby Queen corn from seeds, sow them directly into the soil, about 1-2 inches (2.5-5 cm) deep and 9-12 inches (23-30 cm) apart. Alternatively, you can also start your corn seeds indoors 2-3 weeks before the last frost date and transplant them outdoors once the soil has warmed up.
Remember to provide adequate spacing between each row to allow for proper air circulation and avoid overcrowding the plants. The recommended spacing between rows is about 30-36 inches (76-91 cm).
When selecting a planting site for your Ruby Queen corn, choose a location that receives full sun for most of the day. Corn plants thrive in sunlight and require at least 6-8 hours of direct sunlight to grow and produce healthy ears of corn. Additionally, make sure the soil is well-draining to prevent waterlogging, which can lead to root rot and other diseases.
Consider incorporating a balanced fertilizer into the soil before planting to provide essential nutrients for the corn plants. A fertilizer with a ratio of 10-10-10 or similar can help promote healthy growth and development throughout the growing season.
As your Ruby Queen corn plants begin to grow, monitor them regularly for signs of pests or diseases. Common pests that may affect corn include corn earworms, cutworms, and aphids. By catching any issues early, you can take appropriate measures to protect your crop and ensure a successful harvest.
Harvesting Ruby Queen corn in Wisconsin typically occurs in late summer to early fall, around 75-85 days after planting. Look for signs of maturity such as brown silks and firm kernels when gently pressed. Enjoy the sweet and flavorful taste of freshly harvested Ruby Queen corn, whether eaten fresh off the cob or incorporated into your favorite recipes.
When to Harvest or Pick Ruby Queen Corn in Wisconsin
After patiently nurturing your Ruby Queen corn plants throughout the growing season, it’s time to reap the rewards of your efforts. The ideal time to harvest or pick Ruby Queen corn in Wisconsin is typically 18-22 days after the silks appear on the ears.
One reliable method to determine the readiness for harvest is to gently peel back the husk and examine the kernels. Ripe Ruby Queen corn should have plump and juicy kernels with a milky texture and a sweet aroma. Avoid harvesting the corn too early as the kernels may not be fully developed and may lack the desired sweetness.
When harvesting, it’s recommended to hold the stalk firmly and twist the ear downward, pulling it away from the plant. This technique helps to avoid damaging the plants and ensures that you get the entire ear of corn. Once harvested, enjoy your delicious Ruby Queen corn immediately for the best flavor and texture.
