Treebate Program Details

Every tree planted in Portland contributes to clean rivers and healthy watersheds. So, if you plant an eligible tree on a residential property between September 1 and April 30, Environmental Services will credit your city water/sewer utility bill for half the purchase price per tree up to $15 (small), $25 (medium) or $50 (large) depending on mature tree size and stormwater management potential.

Protect Your Investment

Late fall through early spring is prime tree planting season. Be sure to plant your tree correctly and give it proper care and maintenance. Newly planted trees require deep weekly watering (~10 gal.) during the dry summer season from June through September.
