While people are supposed to drink about eight glasses of water a day, a tree in Ohio with a 10’ canopy can require as much as 100 gallons a day!
There are a couple of crucial considerations when it comes to watering trees. Insufficient water can lead to poor outcomes, including killing the tree. Too much water without sufficient aeration and drainage can have the same result.
A quick, easy way to test is to use a screwdriver to get about 2 – 3 inches down into the soil. If that soil feels moist to the touch, it’s exactly how it should be. If it’s dry, then it’s time to water.
Watering a young tree (<25 years old) is a matter of watering the roots around the trunk. You don’t want to flood the tree trunk, nor do you want to water outside the root ball.
Older trees (>25 years or a trunk over 12” in diameter) require deep watering completed occasionally. You’re looking at about 10 gallons per 1” of trunk diameter per week during dry conditions.
So how do you get that water to your trees, without standing around with a hose all day?
There is a range of solutions, from slow-release water bags, bubbler hoses, and overhead irrigation systems, through to a 5-gallon bucket with holes drilled in the base.
Citygreen has shown exceptional outcomes with the healthy and fast growth of trees by combining soil vault systems, such as Stratavault, with perforated flexible piping systems around the root ball, for example, the Snorkil products.
By creating space for adequate aeration with the Stratavault, you can limit excessive soil compression, and the perforated pipes provide airflow and enable water to be piped directly into the roots.
Combining systems like these in urban areas with permeable pavements, and connecting roof water systems to tree pits helps harvest stormwater, better managing both tree watering needs and stormwater management.
