Putting away your tree and decorations? For residential customers of Monterey City Disposal, trees can be placed next to your yard waste cart. Trees under 6' tall do not need to be cut. Trees over 6' must be cut in half. All decorations, stands and lights need to be removed. Trees will be collected for the first two weeks of the new year. After the first two weeks, trees must be cut and placed in the yard waste cart.
