The amount of water a tree needs depends on many variables and not least of all, the species. For example, a plains cottonwood can live on much less water than a white ash. To find out how much your tree needs, measure (or estimate) its diameter at four feet off the ground, then multiply that number by six. The total is approximately how many gallons of water you should use per watering. A tree with a ten inch diameter at four feet should be given 60 gallons of water per watering. This may seem like a lot of water for larger trees, but keep in mind this only needs to be done once or twice a month. Moreover, using a larger volume ensures sufficient water becomes available to the tree. Spacing the watering applications apart is also important. This allows the soil to properly aerate and gives the tree the oxygen it needs. During hot months (July/August) with little rain, water established trees twice.
Winter Watering Is Very Important
Water trees and shrubs once a month during the dormant season. This becomes critical when moisture levels drop below normal averages. Dry, windy conditions can also lead to cell damage and plant tissue death, causing the plant to lose portions of its crown or die. Winter watering can be inconvenient but is extremely important.
