Newly planted arborvitae should be watered deeply enough to keep the soil evenly moist, typically about one inch of water per week during the first growing season to support root establishment and avoid transplant shock. For newly planted arborvitae, ‘low and slow’ is the preferred method, as their soil needs to be consistently moist. Watering should be done every other day after 10 days, then every 3-4 days every week after that. Duration: Water slowly for 30–45 minutes to encourage deep root growth. After the first full growing season, arborvitaes become more drought-tolerant but still benefit from regular watering during dry periods. Water once every 10–14 days if there is no rain. Watch for early signs of stress like wilting tips or dull foliage. Newly planted Arborvitae require thorough watering to help settle soil around the roots and remove any air pockets. A weekly soaking is recommended during the first year after transplant, especially if you planted in a dry climate. During the first growing season, newly planted arborvitaes should be watered deeply once a week, with adjustments based on rainfall, temperature, and soil type. During the first few weeks after planting, the root ball should be kept continuously moist, often requiring daily watering for the first 10 to 14 days. After this initial period, frequency scales back to a deep watering two to three times per week, depending on weather and soil type. Immediately after planting, a deep, thorough watering helps settle the soil around the roots and removes air pockets. For the initial 10 days, newly planted arborvitae may require daily watering, often with a slow trickle for 2-4 hours, or until the soil is moist about 5 inches deep. Once planted, you want to first give the arborvitae a deep, thorough drink that saturates the roots and gets rid of any air pockets in the planting hole. Then, for the next two seasons, or longer for really large specimens, offer a weekly soak at minimum. You’ll want to water it weekly or twice weekly during the growing season to maintain a moist site. This frequency can change if there is natural rainfall or if the weather is cool and the dirt stays moist. Immediately after planting, the initial watering should be a deep, thorough soaking to settle the soil and eliminate air pockets. For the first week or two, new plantings may require daily deep watering, especially in warm weather, to keep the root ball consistently moist.
