Ruby Queen Corn is a popular variety of sweet corn that is well-suited for growing in Minnesota. With its delicious taste and vibrant red kernels, it is no wonder that many gardeners in the state choose to plant this variety in their gardens. In this article, we will explore everything you need to know about when to plant Ruby Queen Corn in Minnesota, as well as how to grow it successfully.
Climate & Hardiness Zones in Minnesota
Before diving into the specific details of planting and growing Ruby Queen Corn in Minnesota, it is important to understand the climate and hardiness zones in the state. Minnesota generally falls into USDA hardiness zones 3-5, with some areas in the southern part of the state reaching zone 6. This means that the state experiences cold winters and relatively short growing seasons.
Minnesota’s climate is characterized by its significant temperature variations throughout the year. Winters can be harsh, with temperatures dropping well below freezing, while summers can bring warm and humid conditions, ideal for plant growth. The state also experiences a moderate amount of rainfall, providing natural irrigation for crops like Ruby Queen Corn.
It is crucial to choose corn varieties that are suitable for the specific hardiness zone in which you are located. Ruby Queen Corn is known to thrive in zones 3-8, making it a great choice for most parts of Minnesota. Its ability to tolerate cooler temperatures makes it a reliable option for gardeners in the state.
When to Plant Ruby Queen Corn in Minnesota
Knowing the correct time to plant Ruby Queen Corn is crucial for a successful harvest. In Minnesota, it is best to plant this variety in late spring or early summer, once the soil has warmed up and the threat of frost has passed. This is typically around mid-May to early June, depending on your specific location and weather conditions.
Before planting, prepare the soil by removing weeds and loosening it with a garden fork or tiller. Corn plants require well-draining soil with a pH level between 5.8 and 7.0. Adding organic matter, such as compost, can improve the soil’s fertility and structure.
When planting Ruby Queen Corn, space the seeds about 8-12 inches apart in rows that are 30-36 inches apart. Plant the seeds at a depth of 1-1.5 inches. For better pollination and ear development, it is recommended to plant the seeds in blocks or multiple rows instead of a single long row.
It’s important to monitor the moisture levels in the soil after planting. Corn plants need consistent moisture, especially during the critical stages of tasseling and silking. Consider using a soaker hose or drip irrigation system to ensure the plants receive adequate water without wetting the foliage, which can lead to disease.
In addition to proper watering, applying a balanced fertilizer when the corn plants are knee-high can help promote healthy growth and development. Look for a fertilizer with a ratio of 10-10-10 or similar, and follow the manufacturer’s instructions for application rates. Avoid over-fertilizing, as this can result in excessive foliage growth at the expense of ear production.
As the corn plants grow, be on the lookout for common pests such as corn earworms and European corn borers. Consider using natural predators or organic pest control methods to manage infestations while minimizing the use of chemical pesticides, which can harm beneficial insects and pollinators.
How to Grow Ruby Queen Corn in Minnesota
Once you have planted your Ruby Queen Corn seeds, taking care of them properly will ensure a healthy and bountiful harvest. Here are some essential tips for growing this variety in the Minnesota climate:
- Provide Adequate Water: Corn plants require consistent moisture throughout the growing season. Water them regularly, aiming for about 1 inch of water per week. If rainfall is insufficient, consider using a drip irrigation system for efficient watering.
- Fertilize Appropriately: Corn plants are heavy feeders and will benefit from regular fertilization. Before planting, incorporate a balanced fertilizer into the soil. Additionally, side-dress the plants with nitrogen-rich fertilizer when they reach a height of 12 inches and again when they begin to tassel.
- Control Weeds: Weeds can compete with corn plants for nutrients and sunlight, so it is important to keep the garden free from weeds. Mulching can help suppress weed growth and retain soil moisture.
- Protect from Pests: Corn is susceptible to various pests, such as corn borers and earworms. Monitor your plants regularly and take appropriate measures to control pests if necessary. Using row covers or applying natural insecticides can be effective methods.
- Support the Plants: As the corn plants grow, they may become top-heavy. To prevent them from falling over during strong winds or heavy rains, provide support by gently tying the stalks to stakes using garden twine.
When it comes to growing Ruby Queen Corn in Minnesota, it’s important to understand the unique challenges that the climate can present. The state’s cold winters and relatively short growing season can make it a bit more challenging to achieve a successful harvest. However, with the right techniques and care, you can still enjoy a bountiful crop of delicious Ruby Queen Corn.
One important aspect to consider is the timing of your planting. In Minnesota, it’s best to wait until the soil has warmed up sufficiently before sowing your corn seeds. The ideal soil temperature for planting corn is around 50 to 55 degrees Fahrenheit. Planting too early can result in poor germination and stunted growth, so it’s worth waiting for the right conditions.
Another factor to keep in mind is the need for pollination. Corn plants rely on wind or insects to transfer pollen from the male flowers (tassels) to the female flowers (silks). In Minnesota, where the growing season is relatively short, it’s crucial to ensure good pollination to maximize your corn yield. To encourage pollination, consider planting your corn in blocks rather than long, single rows. This will increase the chances of pollen reaching the silks and result in more fully developed ears of corn.
When to Harvest or Pick Ruby Queen Corn in Minnesota
Harvesting Ruby Queen Corn at the right time is crucial to enjoy its peak flavor and sweetness. Generally, this variety is ready for harvest approximately 75-85 days after planting, depending on the specific weather conditions and growing practices.
One way to determine if the corn is ready to be picked is to gently peel back the husk and examine the kernels. The kernels should be plump, well-filled, and emit a milky substance when pressed. Avoid harvesting too early as the corn may not be fully developed, resulting in a less satisfying eating experience.
To harvest Ruby Queen Corn, grasp the ear firmly and snap it down and away from the stalk. Twist the ear to detach it completely from the plant. If the corn is not immediately consumed, store it in the refrigerator or blanch and freeze it to preserve its flavor.
Frequently Asked Questions
1. Can I grow Ruby Queen Corn in containers?While it is possible to grow corn in containers, Ruby Queen Corn may not be the best choice for container gardening due to its size and height. This variety can grow up to 7-8 feet tall and needs ample space for the roots to develop and support the plant’s growth.
2. How do I know if my soil has the right pH level for growing corn?Testing the pH level of the soil is a practical way to determine its suitability for growing corn. Soil testing kits are readily available at garden centers or through agricultural extension offices. Aim for a pH level between 5.8 and 7.0 for optimal corn growth.
3. Can I save the seeds from Ruby Queen Corn for next year’s planting?Yes, you can save the seeds from Ruby Queen Corn for future planting. It is essential to select fully mature ears with well-developed kernels for seed saving. Allow the ears to dry completely on the plant before harvesting the seeds. Store the seeds in a cool, dry place until the next growing season.
