Parke Diem

Hoyt Arboretum Friends is excited to partner once again with the Portland Parks Foundation on Parke Diem! This event brings hundreds of volunteers to parks all over the city in an effort to raise awareness about the role of parks in our communities.

Friday 10/10 from 9am-12pm volunteers will be helping out with re-potting plants that have outgrown their current homes, trail work, and preparing ground for new plantings on Saturday.

Saturday 10/11 from 9am-12pm we'll be planting, removing ivy, hauling debris, and doing some more trail work.

To join us for this exciting day of seizing trees, days, and parks, just register here!

Kids with adults are welcome, and we'll make any accommodation we can to make this event accessible for anyone interested in participating! For more information, please contact Heather Wilkinson
