Climate & Hardiness Zones in Washington
Washington’s climate varies across the state, from the mild coastal regions to the hotter and drier eastern areas. Understanding the climate and hardiness zones in Washington is crucial for successful corn cultivation.
According to the United States Department of Agriculture (USDA), Washington is divided into USDA hardiness zones 4 through 9. Zone 4 is the coldest region, experiencing average minimum winter temperatures between -20 and -30 degrees Fahrenheit (-28 to -34 degrees Celsius), while Zone 9 is the mildest, with average minimum winter temperatures between 20 and 30 degrees Fahrenheit (-6 to -1 degrees Celsius).
It is essential to choose corn varieties that are adapted to the specific hardiness zone you are in. This ensures that the corn will be able to withstand the minimum winter temperatures and thrive in the local climate.
When to Plant Corn in Washington
The timing of planting corn in Washington depends on several factors, including the last average frost date and soil temperature.
As a general guideline, corn can be planted in Washington when the soil temperature reaches a consistent 50 degrees Fahrenheit (10 degrees Celsius) or higher. This typically occurs in late spring or early summer, after the last frost date.
For specific planting dates, consult the local agricultural extension office or reference the USDA planting zone maps. These resources provide valuable information on the recommended planting dates for various crops based on the average climate in your specific area of Washington.
When planting corn, it is important to prepare the soil by removing any weeds and incorporating organic matter like compost or well-rotted manure. This helps improve soil fertility and drainage, promoting healthy corn growth.
Here is a step-by-step guide on how to plant corn in Washington:
- Choose a sunny location with well-drained soil.
- Prepare the soil by removing weeds and incorporating organic matter.
- Plant corn seeds 1 to 2 inches deep and 8 to 12 inches apart in rows that are spaced 2 to 3 feet apart.
- Water the newly planted seeds thoroughly.
- Mulch the soil to conserve moisture and suppress weed growth.
- Monitor the soil moisture regularly and water as needed.
- Protect young corn seedlings from birds or other pests.
When to Harvest or Pick Corn in Washington
The timing of corn harvest in Washington varies depending on the corn variety and environmental conditions. Generally, corn is ready to be harvested when the ears are fully developed, the kernels are plump, and the silks have dried out.
Most sweet corn varieties in Washington are ready for harvest around 70 to 80 days after planting. However, the maturity length may vary depending on the variety and growing conditions. It is essential to refer to the specific instructions provided with the corn seed or consult local agricultural resources for more accurate information on the maturity length of different corn varieties.
To determine if corn is ready for harvest, gently peel back the husk and press a kernel with your thumbnail. If a milky substance is released, the corn is ready to be picked. If the kernels are clear or doughy, the corn needs more time to mature.
When harvesting corn, it is recommended to do so early in the morning when the temperatures are cooler. This helps preserve the corn’s sweetness and tenderness.
Here are the steps for harvesting corn in Washington:
- Check the corn for signs of maturity, such as fully developed ears and dried-out silks.
- Gently peel back the husk of a few ears and press a kernel with your thumbnail to check for milky substance.
- If the corn is mature, hold the stalk firmly and pull the ear downward with a quick, twisting motion to detach it from the plant.
- Remove the husks and silk from the harvested corn.
- Store the corn in a cool place or refrigerate immediately to maintain freshness.
