Does corn need lots of water?

Water sweet corn whenever the soil surface dries out, but don’t saturate the soil. The surface should feel just moist to the touch and water should drain away from around the plants within 10 to 20 seconds. Water first thing in the morning so any moisture that gets on the leaves has time to dry during the day.
How much water does a corn plant need daily?
Daily corn water use averages between 0.15 and 0.20 inches per day (Table I). The plant’s roots are concentrated in the top 18 inches of soil if there are no soil-limiting factors such as compaction, impermeable layer, or gravel.
The simple answer is that irrigation should commence whenever soil moisture becomes limiting. We often see corn leaves start rolling or wilting the first week or more we go without rain and temperatures drastically climb into the upper 80’s, despite plentiful moisture in the soil.

Is it normal for corn leaves to yellow?
Yellowing corn leaves are most probably an indicator that the crop is deficient in some nutrient, usually nitrogen. Corn is a grass and grass thrives on nitrogen. The plant moves nitrogen up the stalk so a nitrogen deficiency manifests itself as corn leaves turning yellow at the base of the plant.

Should I mist my corn plant?
A daily misting with water can be helpful to keep your corn plant healthy.

What is whorl stage corn?
Twisted whorls sometimes develop in young corn plants early in the rapid growth phase. The cause is not well understood. The tightly twisted whorls eventually unwrap to reveal yellowish upper leaves that turn green after a few days of exposure to sunlight. Effects on yield are essentially nil.

What happens if you over fertilize corn?
