Watering is the most important factor in maintaining the survival of your
newly laid grass. Do not water at night. Early morning hours are recommended
in order to reduce disease potential.
When sod is harvested, the plant's root system has been cut off. At this
time, the only way for the plant to receive water is through the leaf.
Therefore, water must be applied directly on top of the sod so the leaf
will receive the water. The plant will then take the water through the
leaf and carry it down into the plant. Once the sod reestablishes a root
system, it can then remove water from the soil. At this time, you can
reduce the amount of water being applied to the grass.
Wilt is a condition in which the leaves and stems droop and die due to
lack of moisture inside the plant. Wilt occurs when there has not been
enough water applied to the grass. It can be recognized by a blue-gray
color on the leaf of the plant. The blades will also shrivel and close
up. Water must be applied as soon as possible to prevent permanent damage
to the grass. When water is applied, the blade will start to open back
up and its green color will return.
The sod must be watered as many times a day as necessary to avoid wilt.
Generally, once in the morning and then once in the mid afternoon for
about 20-30 minutes in each area would be enough. The goal is to give
your grass enough water to keep it from wilting. Watering will vary on
a day-to-day basis. For instance, windy days might require more watering
because the plant dries out faster.
