What are those green bags on the newly planted trees?
Newly planted trees are under severe water stress right after transplanting, and they will remain under water stress for the first several years after planting. The city installs Treegator bags on all newly planted trees. These bags deliver a high volume of water (up to 20 gallons!) directly to the root system of a newly planted tree and slowly release this water over a 6 to 10 hour period. They are typically refilled once a week, thus reducing premature tree death and increasing establishment time.
