corn is a warm-season vegetable, meaning it requires warm temperatures to germinate and grow. Plant Black Aztec corn when soil temperatures are at least 55 degrees Fahrenheit after the last frost date. Full sun and well-draining, rich soil are a must for this crop. Black Aztec corn will benefit from a 2-inch layer of compost mixed into the top 6 inches of soil at the planting site. Plant seeds in groups of three spaced every nine to 12 inches along a row. Cover each seed grouping with 1 1/2 inches of soil and water thoroughly. Since this corn variety is open-pollinating, three to four short rows spaced 30 to 36 inches apart allow for adequate pollination.
Although B corn is drought tolerant, supplemental watering is important to ensure a healthy, mature crop. It will grow in dry conditions, but cobs will be small with small, hard kernels. Soil moisture is especially critical when plants produce tassels for pollination and during fruit ripening. This corn variety grows best with at least 1 inch of water per week. Water corn rows when rainfall is scarce and when the top 1 inch of soil becomes dry.
