Newly planted trees require frequent watering initially to keep their root balls moist and support root establishment. Here is a recommended watering schedule based on expert guidance:

• First 1-2 weeks after planting: Water daily to thoroughly moisten the root ball and surrounding soil. This frequent watering helps the tree cope with transplant shock and supports root growth

• Weeks 3 to 12 after planting: Gradually reduce watering frequency to every 2 to 3 days. This period encourages roots to extend into the surrounding soil while still ensuring adequate moisture

• After 12 weeks (3 months) and until roots are established: Water about once a week, providing a thorough soaking when the soil begins to dry out. This weekly watering typically continues through the first growing season or two, depending on tree size and weather conditions

• During hot, dry weather or summer: Water more frequently if soil dries out quickly. For example, some recommend watering every other day with about 20 liters (2 buckets) during peak summer heat

• Long-term care: Small trees usually need regular watering for 1-2 growing seasons; larger trees may require occasional watering for 3-5 years until fully established

Additional tips:

• Water slowly and deeply at the base of the tree to ensure moisture penetrates the entire root ball and surrounding soil

• Use mulch around the base to retain moisture and reduce evaporation

• Check soil moisture by digging 4-6 inches deep; water when soil feels dry but not soggy

In summary, start with daily watering for the first week or two, then taper to every 2-3 days for the next several weeks, and finally reduce to weekly watering as the tree establishes, adjusting frequency based on weather and soil moisture
