Hose. Since trees require so much water, standing there with your hose will be extremely time-consuming. In addition, watering with the hose on high pressure will shower the tree with more water than the soil can absorb, which will result in wasted water run-off. A more efficient method in using a hose is to turn it on as low as possible so water is slowly dribbling out. After 20-30 minutes, move it to a new location under the canopy. Keep repeating until the tree’s drip zone has been sufficiently watered. Depending on the size of the tree, this may take 1-2 hours — so make sure to set your timer.
Soaker Hose. An easier and efficient method is using a soaker hose that is placed under the tree’s canopy. Soaker hoses are porous and allow water to slowly seep out. This gradual release of water minimizes wasted water and maximizes water absorption. The soaker hose should be placed in a circular pattern under the canopy of the tree and turned on for an hour or more. The goal is for the water to penetrate eight inches into the ground, which can easily be determined using the screwdriver test. Push an 8-inch screwdriver into the ground. If it pushes easily all the way, the ground is moist. Easy does it!
Dripline. The easiest method to watering your tree is using a drip irrigation system. However, it is also one of the most difficult to install. But once installation is complete, the rest is a no-brainer. Just like with a soaker hose, the dripline should be set in a circle under the canopy and run for an hour or more, contingent on factors such as the tree’s size, species, and climate.
Sprinkler. Sprinklers are another common system for watering landscape. Like the drip system, installation can be time-consuming and difficult, but once completed, the work is automatically performed for you and can be adjusted according to the tree and the season. Sprinklers are great for watering lawns and any area of land that is mostly covered with landscaping, however when they are used to water trees that are not heavily surrounded by other plants, then weeds will become an issue.
Bucket. If you need an easy method to water your tree that doesn’t require much time and doesn’t require the purchase of any additional “fancy” tools, you can always use the good ol’ 5-gallon bucket that is hanging out in your garage. Drill holes on the bottom portion of the bucket and place it in the tree’s drip zone. Fill the bucket with water and let it empty out. Then move the bucket to a new location, and repeat the previous step until the tree has received a sufficient amount of water.
