During the winter months, landscape plants such as lawns, trees, and shrubs may appear dormant and brown but still require periodic watering to survive. Experts recommend watering these plants one to two times per month from November through April, with particular attention in March and April when new roots begin to form. It is advised to water on warm days when temperatures are above 40 degrees Fahrenheit and the soil is not frozen, ideally at midday so the water can soak in before freezing.
Recent precipitation that moistens the soil deeply can allow for a longer interval between watering sessions. The focus should be on newly planted lawns, trees, shrubs, and flowers. Established lawns and trees in sunny or exposed areas also need attention during dry periods. However, cacti, succulents, buffalo grass, blue grama, and other low-water xeriscape plants do not require winter watering.
Watering should be done using a hose-end sprinkler or watering wand since automatic systems are typically off during winter. Water slowly to ensure deep penetration into the soil. To measure effectiveness, place cups near what is being watered; continue until each cup contains about half an inch to one inch of water. Afterward, hoses should be detached from spigots to prevent freeze damage.
Homeowners are reminded that their wastewater bills are calculated based on water use from December 1 through the end of February.
A cautionary note highlights that shrubs and trees lacking sufficient moisture may send roots searching for water sources in wastewater pipes—a common cause of pipe damage. Repairs can be disruptive and costly since service lines are generally a homeowner’s responsibility. Regular pipe inspections are recommended at least once a year or more frequently in older neighborhoods with many mature trees.
