Watering Your New Trees and Shrubs

Since Colorado’s Front Range is a semi-arid environment, all newly planted trees and shrubs will need supplemental water.

Apply as much water as the size of the pot or root ball each week during the growing season. For example, five gallons for a number five pot. For balled and burlap stock, apply 10 gallons of water for each trunk diameter inch. For example, apply 20 gallons of water for a two-inch diameter tree.

Trees may be planted with soil mounded up around the outer edge of the root ball forming a dam. This will help the tree retain water and direct it to the root ball. To water these trees, fill the well with water each week.

Regular watering from lawn sprinklers is usually enough for newly planted shrubs. Too much water will kill a new plant just as quickly as not enough water! Trees and shrubs native to semi-arid climates require less water to establish. To test if the soil is too dry, take a handful of dirt from around the plant and squeeze it in a fist. If it clumps up, there is sufficient moisture. If it crumbles, the soil is too dry. Check the root ball moisture as well as the surrounding soil.

Most importantly, enjoy your new tree or shrub! Keep in mind that growth typically happens after three years once the plant is able to establish a substantial root system. If you have any questions, we are here to help!
