Watering corn

Young sweet corn plants have a rather coarse shallow root system, but as the plants mature the roots become more fibrous and can penetrate to a depth of 3 feet or more in the taller varieties. The soil should be well irrigated prior to planting. After germination, start regular irrigation using drip or furrow irrigation when the plants get 3 to 6 inches high. Weekly irrigation may be required depending upon the soil type and the temperature up until harvest. On hot days the corn leaves may roll up for an hour or so without harm. However, irrigation is needed if the leaves remain rolled up in the early morning.

Place a hose or drip tape between rows of plants
