The Polly Hill Arboretum and t

Polly Hill Arboretum offers a way to get outdoors and explore the off season on the grounds.

A chance to clean up the grounds and then a later opportunity to check out the night sky with amateur astronomer Barbara Caseau is coming up Thursday, Oct. 24 at Polly Hill Arboretum. Grounds volunteer day is from 9 a.m. to noon and is a basic fall sprucing-up event. Bring gloves and dress for the weather.

Marlene Snecinski, also known as Mushroom Marlene, leads a fall walk foraging for wild mushrooms at Polly Hill Arboretum in West Tisbury on Saturday, Oct. 5, from 2 to 4 p.m. She will point out fun fungi facts and discuss mycophagy along the way.

Preregistration is required for this mushroom walk-and-talk so call 508-693-9426 for more information or visit pollyhillarboretum.org.

It’s all about Brooklyn at the Polly Hill Arboretum on Wednesday, Sept. 18. Chris Roddick, senior arborist at the Brooklyn Botanical Garden kicks it off with a talk about pruning techniques and tool maintenance from 1 to 3 p.m. There will be a hands-on demonstration and a chance to practice newly learned pruning prowess. Bring hand pruners if you have them. Cost for this event is $20 or $10 if you’re a member of Polly Hill.

The perfect time to plant is upon us and the Polly Hill Arboretum offers its fall plant sale from 10 a.m. to 2 p.m. on Sept. 14. Staff will be available to answer questions about the Vineyard climate and plant selection.
