Notes From the Field: Missed Christmas Tree Pickup? Email 1-23-18 Uh oh, you’ve missed Christmas Tree pickup! Here’s what you need to do: If the tree is free of decorations, tinsel and stand, cut it up and place it in your green cart. If your tree has been flocked/spray painted, it cannot be composted and must be cut up and placed in your trash cart. Trees can also be taken to any San Joaquin County Landfill facility. As a reminder, Christmas trees are collected in the City of Stockton between the weeks of Dec 26 – Jan 15 each season. Read more Notes From the Field.
