The Q&A Archives: Corn

Question: I planted several rows of silver queen corn this spring. I planted the corn in furrows so I can pull dirt to them. My corn is about 6

Answer: Corn is a heavy user of nitrogen. Fertilize in the spring, again when the corn is 8 inches tall, and again when the plants are 18 inches tall. Side-dress between the rows, using one-third of a pound of complete, well-balanced fertilizer on each side of a 10-foot-long row. Hill soil around the plant roots at this time to help support the stalks.

Earworms can be discouraged by placing a single drop of mineral oil on the silks after they have turned color (which indicates the ear has been pollinated). If you put the soil on the silks too soon, it will prevent pollen from entering and will result in an ear with no kernals. It usually takes 5-7 days after the silks appear for the ears to be pollinated so watch for a color change and then apply the mineral oil.

Best wishes with your corn patch!
