Proper watering, even for drought tolerant species, is one of the most important things you can do to help your new tree establish itself after planting. The main objective is to keep the surrounding soil and roots moist but not wet to a depth of 36 inches. The best way to achieve this is to install a watering berm that circles the tree approximately 18 inches from the stem or trunk that controls where the water enters the soil and ensures it stays in close proximity to the new tree roots. When the tree is first planted, it will typically require more water than once it is established. For new trees, this means watering two to three times per week with between three and five gallons of water per application during the hot summer months and one to two times per week with between three and five gallons of water in the cooler fall, spring and winter months. While continuous monitoring of soil moisture should occur for at least the first three years, supplemental watering can frequently be tapered down to monthly and then stopped entirely by the end of the third year.
