One option is to turn the hose to a slow dribble and place it on the ground near the trunk.
Slow drip watering trees.
Instead of using a hose or sprinkler try a drip irrigation system.
Mulching trees and shrubs maximizes water uptake.
Drip systems emit a slow and steady flow of water allowing for deep penetration of the soil and stronger tree roots.
A soaker hose such as the one in our snip n drip soaker system applies water slowly so it soaks in rather than running off.
Trees are better served by watering methods that apply water slowly right at soil level.
It may take several hours to properly water a single mature tree.
Treegator original is a slow release watering bag that is perfect for newly planted or established trees from a minimum of 1 inch to a maximum of 8 inches in trunk diameter caliper with branches beginning at least 25 inches from the ground or higher.
If you provide trees with frequent shallow watering the tree develops shallow.
Make a reservoir over the root ball for watering.
It provides a slow measured flow of h2o straight to tree and shrub roots.
A single bag fits tree trunks from 1 inch to 3 inches in diameter.
After half an hour move it a couple of feet around the trunk.
Keep moving the hose from place to place until it has dribbled for an hour or even two hours for a large tree.
