Delta Park Orchard

Apple trees growing on a branch.

Urban Forestry planted a demonstration orchard outside of our North Portland office in 2010. The orchard includes 55 diverse fruit and nut trees, from the traditional apples, pears, and cherries to paw paws, persimmons, jujubes, mulberries, and medlars. 

Check out all the orchard trees

Learn the difference between the types of fruit tree pruning - such as open vase and central leader, discover new species that thrive in Portland, and take a taste of a few early ripening fruit!

Care Needed

What happens when you provide annual care for a tree for a decade and then none for one year? Quite a lot of overgrowth is the answer! Without having volunteers visit them in over a year, these trees have taken on some wild water sprouts and other maintenance needs that can become a hazard if left unaddressed. 

Here is what we will be doing to care for the orchard:

  • Removal of competing plant growth
  • Catalog species signs and collect damaged
  • Pruning of water sprouts and address needs of orchard trees
  • Provide mulch and soil needs

All tools and materials needed will be provided on-site.

Portland Parks & Recreation Urban Forestry's mission is to manage and ensure Portland's urban forest infrastructure for current and future generations. Portland’s urban forest consists of 236,000 street trees, 1.2 million park trees, and innumerable private property trees.

Urban Forestry is involved in managing or regulating all of these trees to differing degrees. Urban Forestry staff issue permits for planting, pruning, and removal of all public and some private trees and are on call 24/7 to respond to tree emergencies.
