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 particular tree type and region.

Fill Once a Week

Treegator Bags are efficient and so effective. On most new plantings you'll only have to re-fill them once every 5 to 7 days.

Deep Saturation

Slow, deep applications of water on a regulated schedule are the best way to effectively and efficiently irrigate a newly planted tree or shrub.

A Treegator Bag can easily be installed and filled in less than 5 minutes with no tools. No digging, no staking, and no other parts to install or buy.

Double Up
