Why are the leaves of my corn plant turning yellow?

A cold, wet soil during the winter months makes it hard for your plant to access nutrients. This leads to the leaves turning yellow and falling off.
Why is my corn looking yellow?
Early season corn coming out of cooler spring into a warm summer can lead to temporary yellowing and wrinkled leaves as the corn grows faster than it can unroll. This may cause some twisting in the whorl, but in most cases the corn will resolve itself as crop progresses.
Why are the leaves on my corn plant turning yellow and brown?
Corn plants most commonly get brown leaf tips due to underwatering or inconsistent watering. Other common causes include water high in fluoride or chlorine, or sources of plant stress such as low humidity, excess fertilizer, excess heat and light, pests, diseases and stress due to acclimation or repotting.
How do I add nitrogen to my corn plant?
Spread the nitrogen in a line on the soil surface about 6 inches from the row of corn. Water the corn as usual to help carry the nitrogen down to the root systems.

Can I put my corn plant outside in the summer?
In summer, the corn plant can live outside, but in winter, keep it indoors in bright light where you can maintain daytime temperatures between 60 and 70 F and nighttime temperatures of 50 to 60 F. Plants grown in light conditions that are too bright can develop streaks and dry patches on the foliage.

What is the best nitrogen for corn?
Nitrogen fertilizer suitable for fall sweet corn should have a mineral content specifically created to enhance the corn plant's growth. For corn, use a fertilizer labeled “16-16-8,” which describes the mineral composition in the fertilizer: 16% nitrogen, 16% phosphate and 8% potassium (following an N-P-K formula).
Can you over fertilize corn?
Fertilizer makes plants grow fast; but too much fertilizer results in weaker plants, not stronger ones. Sweet corn (Zea mays), for example, requires nitrogen and phosphorous to thrive, but too much nitrogen produces stalks so weak that they fall over like felled trees.
Is Triple 13 good for corn?
“Corn loves fertilizer as much as a pig loves to eat corn,” said AgCenter program assistant Bobby Williams. When preparing a garden for corn, apply 4-6 pounds of 13-13-13 fertilizer per 100 feet of row one to three weeks prior to planting.
