In Newfoundland and Labrador, the growing season for corn is relatively short, so it is important to choose varieties that have a shorter maturity time. Here are a few varieties that are known to perform well in this region:
- Early Sunglow: This is a popular variety that matures in around 65 days. It produces sweet, yellow kernels and is well-suited for cooler climates.
- Golden Bantam: A heritage variety that has been grown for many years, Golden Bantam matures in approximately 75 days. It has a delicious, sweet flavor and is known for its tender kernels.
- Peaches and Cream: This variety is a bicolor corn that matures in around 80 days. It produces both yellow and white kernels on each cob, offering a unique and tasty combination of flavors.
- Northern Xtra-Sweet: Developed specifically for cooler climates, Northern Xtra-Sweet matures in about 70 days. It is known for its high sugar content and excellent flavor.
- Silver Queen: Although it takes longer to mature (around 90 days), Silver Queen is a popular variety that produces large, sweet kernels. It is well-suited for Newfoundland and Labrador’s cooler climate.
When selecting corn varieties, it is important to consider the maturity time, sweetness, and flavor preferences. Also, ensure that you provide the corn plants with sufficient sunlight, water, and nutrients for optimal growth.
When to plant Corn in Newfoundland and Labrador
Newfoundland and Labrador, being a province in Canada, has a range of hardiness zones due to its diverse climate and geography. The hardiness zones help gardeners determine which plants are most likely to thrive in a particular region. Here is a breakdown of the hardiness zones in Newfoundland and Labrador:
- Zone 1a: This is the coldest zone in the province, found in the northernmost parts of Labrador. Winter temperatures can drop as low as -50°F (-45°C).
- Zone 1b: Similar to Zone 1a, this zone is also found in the northern regions of Labrador, with similar extreme cold temperatures.
- Zone 2a: This zone covers much of Labrador, including central and southern parts. Winter temperatures range from -45°F to -50°F (-42°C to -45°C).
- Zone 2b: This zone is found in the southern coastal areas of Labrador, where winter temperatures range from -40°F to -45°F (-40°C to -42°C).
- Zone 3a: This zone covers most of the island of Newfoundland, including areas along the west coast. Winter temperatures range from -35°F to -40°F (-37°C to -40°C).
- Zone 3b: Found along the south coast of Newfoundland, this zone experiences slightly milder winter temperatures, ranging from -30°F to -35°F (-34°C to -37°C).
- Zone 4a: This zone covers areas along the east coast of Newfoundland, including St. John’s. Winter temperatures range from -25°F to -30°F (-32°C to -34°C).
- Zone 4b: Found in the central and western parts of Newfoundland, this zone experiences winter temperatures ranging from -20°F to -25°F (-29°C to -32°C).
Considering the hardiness zones in Newfoundland and Labrador, the best time to plant corn would be in late spring or early summer. Corn is a warm-season crop that requires soil temperatures to be consistently above 50°F (10°C) for successful germination and growth. In most regions of Newfoundland and Labrador, this temperature is typically reached in late May or early June.
It is important to note that corn is a heat-loving plant, and the growing season in Newfoundland and Labrador is relatively short. Therefore, it is recommended to choose early-maturing corn varieties that can reach maturity within the available growing season. These varieties are specifically bred to mature in cooler climates and have a shorter growing period.
Additionally, corn requires full sun and fertile, well-drained soil with good moisture retention. It is advisable to prepare the soil by adding organic matter and ensuring proper drainage before planting corn.
By considering the hardiness zones and planting at the appropriate time, along with selecting suitable corn varieties, gardeners in Newfoundland and Labrador can increase their chances of successfully growing corn crops.
When to harvest Corn in Newfoundland and Labrador
In Newfoundland and Labrador, the optimal time to harvest corn is typically in late August to early September. This is when the corn ears are fully developed and the kernels have reached their maximum size and sweetness. It’s important to monitor the corn closely and harvest it before the first frost, as cold temperatures can affect the quality of the corn.
Other considerations
When growing corn in Newfoundland and Labrador, there are a few additional considerations to keep in mind due to the region’s unique climate and growing conditions. Here are some factors to consider:
- Short growing season: Newfoundland and Labrador have relatively short growing seasons, so it’s essential to choose corn varieties with a shorter maturity period. Look for early-maturing or cold-tolerant varieties that can reach maturity within the available growing season.
- Soil preparation: Ensure that the soil is well-drained, fertile, and rich in organic matter. Work compost or well-rotted manure into the soil before planting to improve its fertility and moisture retention capacity.
- Planting time: Wait until the soil has warmed up sufficiently before planting corn seeds. Soil temperature should ideally be around 60°F (15°C) for optimal germination and growth. Consider using black plastic mulch or row covers to help warm up the soil.
- Wind protection: Newfoundland and Labrador can experience strong winds, which can damage corn plants. Consider planting corn in a location that offers some natural windbreaks, or create artificial windbreaks using fences or hedgerows to protect the plants.
- Moisture management: Adequate and consistent moisture is crucial for corn growth. Monitor soil moisture levels regularly and provide irrigation if necessary, especially during dry periods. Mulching around the plants can help retain moisture in the soil.
- Pest and disease control: Keep an eye out for common pests like corn earworms, cutworms, and aphids. Regularly inspect the plants for any signs of damage or infestation and take appropriate measures such as handpicking, applying organic insecticides, or using companion planting techniques to deter pests. Additionally, be vigilant for diseases like common rust or northern corn leaf blight and promptly treat any infections to prevent their spread.
- Fertilization: Corn is a heavy feeder, so regular fertilization is essential. Conduct a soil test to determine the nutrient levels and adjust fertilization accordingly. Apply a balanced fertilizer or organic amendments like compost or well-rotted manure throughout the growing season to ensure the plants receive adequate nutrients.
- Pollination: Corn requires proper pollination for successful seed development. To ensure good pollination, it’s recommended to plant corn in blocks rather than single rows. This allows for better wind pollination and increases the chances of successful seed set.
By considering these factors and adapting your gardening practices accordingly, you can increase your chances of successfully growing corn in Newfoundland and Labrador.
