Supplemental winter watering is critical for plant survival in Colorado, especially in the event of a dry, cold winter. New plantings generally take up to two years to establish a good root system and are particularly susceptible to winter desiccation; although established plants can suffer as well. Lawns with south or west-facing slopes are also at risk of desiccation and are prone to mite damage during warm dry winter months.
Monthly or bi-monthly winter watering is generally recommended and only when air temperatures reach 40 degrees or greater, which usually translates to mid-day. The best way to water larger established trees is with a deep-root watering probe, while smaller trees, shrubs and lawn areas can be watered with a watering wand or hose-end sprinkler. Larger and established trees require about 10 gallons of water per caliper inch per month, while shrubs require about 2-5 gallons per month depending upon the size. Established xeric plants may require less. Please feel free to contact us if you have questions or require assistance with your winter watering.
