Deep Water Saturation is Key
Why is deep watering my tree so important?
Newly planted/transplanted trees, with their greatly reduced root systems and the shock from being removed are in great need of frequently applied deep irrigation. Deep watering keeps moisture concentrations far below the surface, reducing transplant shock and attracting roots into the soil.
How deep is "deep enough"?
Deep watering to a depth of at least 12 inches or more is recommended. Most of the root system of a tree is located within the top 2 to 4 feet of soil. With new trees, it is also recommended that the water be applied directly over the root ball/root mass.
How can I efficiently achieve deep water saturation?
Experts suggest that the best way to efficiently ensure deep water penetration is to slowly and evenly apply a high volume of water in a single application.
