This month the Polly Hill Arboretum abounds with mature overgrown hollies. When untamed, hollies scrape against buildings, interfere with other plantings and block doorways. Homeowners have this plant problem, too.

If you are looking to tame these beasts back into beauties then the Holly Hat Racking Demo is for you. The demonstration begins at 10 a.m. on Saturday, March 15, and runs until noon. It’s free and open to the public.
