Reduce Watering Frequency to Once a Week

Compared to conventional methods, TREEGATOR® Slow Release Watering Bags can greatly reduce your watering frequency.
For most new plantings, a TREEGATOR® Bag only needs to be filled once every 5 to 7 days.

(elapsed time = 8 hrs)

Deep Water Saturation

For most new plantings, one application of water from a single TREEGATOR® Original Slow Release Watering Bag will usually provide enough moisture to last a 1" to 2" caliper new tree planting for up to 7 days.*

Typically, TREEGATOR® Bags are used during the initial 1 to 2 growing seasons (i.e. Spring through Fall) after planting. However, the bags are durable and will last for many years. Meaning that they can be used as a supplemental watering device even after establishment - especially during periods of drought.

*Proper watering frequency can vary depending on several factors (tree and soil type, weather, etc.) These recommendations 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:

How long does it take for a TREEGATOR® Bag to empty?

It typically takes approximately 5 to 9 hours* for a TREEGATOR® Bag to empty.
(*Note: Water release times may vary depending on certain factors such as: soil types, weather conditions, tree types and size, etc. - In some instances, it can take between 5 and 24 hours for single bag to completely empty.)

Why doesn't it take longer for a TREEGATOR® Bag to empty?

When watering, you want to water as deep as possible - not necesarily as long as possible. Watering slowly is the best way to get water deep below the soil - but, watering too slowly causes the majority of the water applied to evaporate before it reaches the root system. TREEGATOR® Bags are designed to provide deep water saturation with no run-off in the least amount of time necessary. You will water your trees and shrubs more efficiently and effectively than conventional methods and spend less time doing it.

Why doesn't a TREEGATOR® Bag need to be filled every day?

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.
