Question: When is it a good time to plant sweet corn?

Answer: You can plant corn from the last week in April until the last week in June. Depending upon your preferences, you can grow early corn or mid-season corn.

Early corn matures in 60 to 70 days. Stalks 5 to 6 feet tall, ears 6 to 7 inches with eight to 12 rows of kernels. Examples: Royal Crest, Early Sunglow, Early Xtra Sweet.

Midseason takes 70 to 80 days. Stalks 6 to 7 feet tall, ears 7 to 8 inches with 12 to 16 rows of kernels. Examples: Golden Beauty, Marcross, Sugar King, Morning Sun.

Late corn takes 80 to 100 days to mature. Stalks 7 to 9 feet tall, ears 7 to 9 inches with 16 to 20 rows of kernels. Examples: Golden Cross Bantam, WK199, Jubilee, Iochief, Illini Xtra Sweet.

White corn includes early (Silver Sweet), late (Silver Queen) and rowless kernel or shoe-peg kernel corn (Country Gentleman). Some authorities recognize Silver Queen as the epitome of sweet corn excellence.

Best wishes with your corn!
