This year’s event will include the Garden Club of St. Petersburg’s annual flower show, free plant and seedling giveaways, an “Ask an Arborist” panel, gardening tool sharpening services, arts and crafts for children, and a free mulch delivery raffle for St. Pete residents.

Food trucks and local vendors will also be on site throughout the weekend.

The festival traces its origins to 1986, when the St. Petersburg Parks Department launched an Arbor Day celebration at Boyd Hill Nature Preserve.

Over the decades, the event has grown into a major community gathering with annual attendance often reaching around 30,000 visitors.

Parking for the festival will be available at Azalea Middle School, the Azalea Youth Soccer League complex, and behind the Walter Fuller Recreation Center.

A free trolley will shuttle attendees to and from the festival grounds.
