Currently the City of Georgetown does not have a recycling program, but you may dispose of your trees the following ways:
TDS will take Christmas trees & citizens can get that mulch for free (not to be confused with the nice mulch that they sell there).
Please refer to the information on the Sanitation Information page, http://recycle.georgetown.org/
If trees or limbs are in roadways or touching utility lines, please contact Georgetown Utility Systems at (512) 930-3555 until 11:00pm. On weekends or emergencies, contact the Georgetown Police Services at (512) 930-3510.
