Welcome to the world of growing corn in Saskatchewan! As an experienced gardener, I understand the importance of timing when it comes to planting this beloved crop. Saskatchewan, with its unique climate and growing conditions, requires careful consideration when deciding on the best time to plant corn.

In this article, we will delve into the factors that determine the ideal planting window, including frost dates, for growing corn in Saskatchewan. Whether you are a seasoned farmer or a novice gardener, this comprehensive guide will equip you with the knowledge you need to ensure a successful corn harvest in the beautiful province of Saskatchewan.

Best varieties of corn to grow in Saskatchewan

In Saskatchewan, there are several good varieties of corn that can be grown successfully. Here are a few popular choices:

  1. AC Gehl: This is a short-season variety that matures in around 78-82 days. It has good yield potential and performs well in cooler climates.
  2. Pioneer 39D26: This is another short-season hybrid that matures in approximately 80-85 days. It has excellent drought tolerance and performs well in dry conditions.
  3. PRIDE G8C34: This is a mid-season hybrid that matures in around 85-90 days. It has good yield potential and performs well under stress conditions.
  4. DKC26-35RIB: This is a mid-season variety that matures in approximately 85-90 days. It has good resistance to diseases and pests and performs well in Saskatchewan’s growing conditions.
  5. 33K73: This is a mid-season hybrid that matures in around 90-95 days. It has excellent yield potential and performs well in high-density planting.

When selecting corn varieties, it is important to consider factors such as maturity length, disease resistance, yield potential, and specific growing conditions. It is always recommended to consult with local agricultural experts or seed suppliers to choose the best variety for your specific location in Saskatchewan.

When to plant Corn in Saskatchewan

In Saskatchewan, there are four main hardiness zones, which are determined by the average minimum winter temperature. These zones help gardeners determine which plants are best suited for their specific region.

  1. Zone 0a: This zone covers the northernmost parts of Saskatchewan, where the average minimum winter temperature ranges from -50°F to -45°F (-45.6°C to -42.8°C). Due to the extremely cold temperatures, it is not recommended to grow corn in this zone.
  2. Zone 0b: This zone covers the central and northern parts of Saskatchewan, where the average minimum winter temperature ranges from -45°F to -40°F (-42.8°C to -40°C). Corn cultivation is still challenging in this zone due to the short growing season and cold temperatures, but it may be possible with careful planning and the use of early-maturing corn varieties.
  3. Zone 1a: This zone covers most of central Saskatchewan, where the average minimum winter temperature ranges from -40°F to -35°F (-40°C to -37.2°C). Corn can be grown in this zone, but it is crucial to select early-maturing varieties and provide optimal growing conditions to ensure a successful harvest.
  4. Zone 1b: This zone covers the southern parts of Saskatchewan, where the average minimum winter temperature ranges from -35°F to -30°F (-37.2°C to -34.4°C). It is in this zone where corn cultivation is most suitable and successful. The longer growing season and milder winter temperatures allow for a wider range of corn varieties to be grown.

The best time to plant corn in Saskatchewan is typically in late spring or early summer, depending on the specific zone. It is important to wait until the soil temperature consistently reaches at least 50°F (10°C) before planting corn seeds. This ensures proper germination and growth. In general, the recommended planting time for corn in Saskatchewan is around late May to early June for most zones. However, for zones with shorter growing seasons (0b, 1a), it may be necessary to start with pre-germinated seeds indoors or use protective measures such as row covers to extend the growing season.

It is also essential to consider the specific variety of corn being planted, as some varieties have different maturity dates. Early-maturing corn varieties are best suited for Saskatchewan’s shorter growing season, while longer-maturing varieties may be more suitable for the southern regions with a longer growing season.

Remember to always check local weather conditions and consult with local gardening resources or extension services for the most accurate and up-to-date information on the best planting times for corn in your specific area of Saskatchewan.

When to harvest Corn in Saskatchewan

The optimal time to harvest corn in Saskatchewan typically falls in late September to early October. However, the precise timing can vary depending on factors such as the specific corn variety being grown, weather conditions, and the maturity period of the chosen variety. It is important to monitor the development of the corn closely and consider factors such as the moisture content of the kernels, the color and dryness of the husks, and the overall health of the plants. Harvesting too early can result in immature corn, while waiting too long can lead to overripe or damaged kernels.

Other considerations

When growing corn in Saskatchewan, there are several additional considerations to keep in mind:

  1. Climate: Saskatchewan has a short growing season with cool nights, so it’s important to choose corn varieties that have a shorter maturity period. Look for early-maturing or short-season varieties to ensure the corn has enough time to reach maturity before the first frost.
  2. Soil: Corn prefers well-draining soil with a pH level between 5.8 and 7.0. Conduct a soil test to determine the nutrient content and pH level of your soil. If necessary, amend the soil with organic matter, such as compost or well-rotted manure, to improve its fertility and structure.
  3. Watering: Corn requires consistent moisture throughout its growing season, especially during pollination. Adequate irrigation is crucial, especially during dry spells. Consider using soaker hoses or drip irrigation to deliver water directly to the roots and minimize evaporation.
  4. Fertilization: Apply a balanced fertilizer before planting to provide the necessary nutrients for growth. Corn is a heavy feeder and requires higher levels of nitrogen, phosphorus, and potassium. Monitor the plants throughout the season and top-dress with additional fertilizer if needed.
  5. Pest and weed control: Watch out for common pests in Saskatchewan, such as corn borers, corn earworms, and cutworms. Monitor your plants regularly and take appropriate measures if you notice any signs of infestation. Implement weed control strategies, such as mulching or using herbicides, to prevent weeds from competing with your corn plants for nutrients and water.
  6. Crop rotation: To prevent the buildup of diseases and pests, practice crop rotation by planting corn in different areas of your garden each year. Avoid planting corn in the same spot for consecutive years.
  7. Support: Depending on the variety and the prevailing winds in your area, consider providing support for your corn plants to prevent them from toppling over during storms or strong winds. Staking or bracing can help keep the plants upright.
  8. Harvesting: Harvest corn when the ears are fully mature, and the kernels are plump and milky. Check the specific variety you are growing for the recommended harvest time. To test for ripeness, peel back the husk and press a kernel with your fingernail; if a milky liquid is released, it is ready for harvest.

By considering these factors, you can increase your chances of successfully growing corn in Saskatchewan.
