Leaf Collection

  • Compost collection includes leaf collection in the fall. Fill your compost cart first, then use paper leaf bags as needed.
  • If setting out leaf bags, you must also put out your compost cart. Compost trucks are top-loading, so the truck operator will need to place the bags in your compost cart and lift them with the truck's mechanical side arm into the top of the truck.
  • Never use plastic bags for leaf collection: they will not be collected.
  • Set out up to 10 additional lawn bags next to your full compost cart on your regular collection day. Leave at least 3 feet of space between bags and the cart.
  • If you have more than 10 bags of leaves in one week, all additional bags placed at the curb will be collected, but only 10 bags will be collected each week. When larger quantities are placed at the curb, it may take several weeks for them all to be collected.
  • During the fall, please leave your green compost cart at the curb after it is initially emptied. Often, a second truck will come to pick up bags and will need your cart to lift leaf bags into the truck.
  • There is no end date for leaf collection. All bags will be collected eventually. Please be patient and put out your compost cart each week. Leaf bags are sturdy and can withstand snow and rain.

Leaf Drop-Off Sites

There are several leaf drop-off locations at which Boise residents can deposit leaves free of charge. The locations, listed below, will have a large dumpster marked “Leaves Only”. These locations are open October 17 - December 11.

  • Only leaves and paper lawn bags in the dumpster.
  • No plastic bags.
  • Do not leave bags outside of the dumpster. If the dumpster is full or has been taken to be emptied, take bags to another site on the list below or return later.
  • Residents may drop off leaf bags at any of the sites at any time.
  • Businesses are not permitted to use the drop-off locations and should take leaves to the Ada County Landfill.

Christmas Tree Collection

Residents who participate in the compost program can compost live (not artificial) trees. First remove all lights, ornaments, tinsel and anything else that is not part of the tree. Cut or saw trees into segments  and place in your compost cart so that the lid can fully close. If you cannot fit all your tree into the cart, bundle remaining segments and set the bundles next to your compost cart on collection day.

Whole Christmas trees placed beside your cart will not be collected.

Residents who do not participate in the compost program but would still like to recycle their tree can take live trees to the Ada County Landfill at 10300 N Seamans Gulch Rd, Boise. Tree disposal is free from December 26 to January 2. Trees will be recycled through the wood waste recycling program.

Residents who are unable to compost their tree can dispose of a live tree in the trash by cutting it to fit in the trash bin. Wreaths and trees sprayed with artificial snow or flock should also be placed in the trash.
