Note that during especially dry and/or hot periods of weather, these watering schedules may need to be increased. Also, trees and shrubs planted in sandy or porous soil should be watered more frequently. Conversely, during periods of rainfall / high moisture, a Treegator® Bag should be filled less frequently*.
*Proper watering frequency can vary depending on several factors (tree and soil type, weather, etc.) This recommendation will NOT guarantee that your tree is being watered properly - Use it only as a guide. Consult a local gardening or tree care professional for more information on proper watering practices for your tree type and region.
Commonly Asked Questions
The amount of water a Treegator® Original is able to hold is dictated by the size of the tree it is used on, as well as the setup (i.e. single bag or double bag setup).
A Treegator® Original can be used to water trees with a trunk caliper of 1" (single bag setup) to 8" (double bag setup).
Taking into account all possible setup configurations, the quantity of water a single Treegator® Original bag can hold averages out to 20 gallons (75.705 liters).
A Treegator® Slow Relese Watering Bag delivers water deep below the soil surface with no run-off - every time.
This means that there is now a high concentration of moisture within the entire soil profile that your new tree or shrub can feed from - potentially for several days.
And, after a deep watering application, allowing the soil to begin to dry out will help encourages deep root growth.
Keeping the soil too moist for too long, or poor drainage at the planting site, can remove the oxygen available to the roots from within the soil and kill a tree or shrub.
