How much water does corn require?

This plant requires good management in terms of watering throughout its entire growth cycle; a lack of sufficient water at this stage of its development causes the ear, when it is produced, to be scabby and tasteless. Young plants should have their surface kept moist, while older ones require their roots to be moistened to a greater depth. When these altered circumstances of adult plants become known, their most common threats are avoided.

Look for signs of water stress. Leaves that curl up in the morning are a sign that the plant is poised for dehydration. New leaves that unfurl very slowly mean not enough moisture is available for the plant. Purple stems imply drought stress on nutrient uptake. If plants are wilting in the afternoon heat, you've got a problem if they don't perk up overnight.

Make use of efficient irrigation systems. Soaker hoses soak the ground directly at the roots and have lower evaporation rates. In contrast, drip systems provide complete control, especially when growing corn in containers. For big plantings, use surge valves that offer even distribution. Remember to always water in the early-morning hours so that you avoid promoting disease.

Prevent damage from overwatering: provide effective drainage! Green thumb or not, if you drown your plants in poorly draining soil, within a couple of days their roots will rot. Yellowing lower leaves, for example, indicate that a plant is wet enough. On clay soils, lighten up dirt around the roots with compost and provide planting mounds in poorly draining areas, leaving the roots out.

Save water with mulching techniques. Spread 5cm of straw mulch to cut evaporation by 30%. Use landscape fabric for container garden beds. Plant cover crops (between rows) that improve the soil's moisture-retaining properties. These measures maintain soil at an ideal moisture content while reducing watering chores.
